See how custom duct transitions solve alignment and space constraints in HVAC retrofits. Discuss drawings, materials and site needs with Metcon Steel.

Replacing HVAC equipment can leave contractors with outlets that do not match the retained ductwork. Custom duct transitions connect different sizes, shapes or centreline positions while accommodating restricted ceiling voids and plant rooms. Their suitability depends on verified measurements, appropriate geometry and coordination with the mechanical design.

When Does an HVAC Retrofit Need a Purpose-Built Transition?

A purpose-built transition is required when new equipment or duct sections cannot connect directly to an existing system. Typical applications include rectangular-to-round connections, size changes, eccentric alignments and offsets around beams, pipework, cable trays or other building services. This problem often arises when replacement equipment has different outlet dimensions or retained ducts cannot be moved without disturbing surrounding services.

The retained ductwork should be assessed for condition, cleanliness, leakage and airflow capacity before reuse. A correctly fabricated transition can resolve a physical mismatch, but it cannot correct undersized ductwork, unsuitable fan selection or an unbalanced air system. Our existing article on custom ductwork for commercial buildings provides broader context for project-specific fabrication.

Measurements and Specifications Required Before Fabrication

Accurate fabrication requires verified connection dimensions, not nominal duct sizes. Measure older ductwork at multiple points and confirm offsets, fixed faces and clearances. The access route must also be checked because a fitting may suit its final position but not pass through the available door or hatch.

Our air-conditioning component fabrication can be assessed against information including:

• Connection sizes: Record each inlet and outlet width, height or diameter, including any irregularities found during measurement.
• Transition geometry: State the available length, offset direction, installed orientation and fixed faces that must remain aligned.
• Construction details: Provide the specified material, pressure classification, reinforcement, joint, flange and sealing requirements.
• Thermal requirements: Identify internal lining, external insulation and vapour-sealing requirements at adjoining sections.
• Site access: Confirm transportable section sizes, lifting constraints and any need for sectional assembly.
• Supporting documents: Supply drawings, photographs, airflow direction and verified site measurements.

Balancing Airflow, Access and Compliance

Custom duct transitions should follow the specified airflow and available fan pressure while remaining practical to fabricate and install. Abrupt area changes, high velocities, extreme aspect ratios and closely spaced fittings can increase pressure loss, turbulence and noise. As AIRAH’s restricted ceiling-space case study demonstrates, limited depth, structural obstructions and insulation thickness can materially affect usable duct dimensions and system design.

The designer confirms airflow and performance requirements, while we fabricate to approved details. Ductwork may also need to comply with AS 4254.2 and relevant NCC requirements. Fire or smoke-control applications may also require the applicable AS 1668 provisions, making approved project documentation more authoritative than general assumptions.

Metcon Steel and Custom Duct Transitions for Retrofits

A successful retrofit needs a fitting that matches documented connections, accommodates the installation route and supports the specified system design. Through Metcon Steel, we fabricate commercial ducting and HVAC components using galvanised steel, stainless steel and mild steel for confirmed project requirements. Providing complete drawings and measurements gives us a defined basis for assessing fabrication before clients request a quote.

Send us your retrofit drawings, connection details and verified site measurements for a project-specific fabrication enquiry.

Metcon Steel explains what to include in a commercial ductwork quote request, from drawings and dimensions to materials, quantities and delivery needs.

Missing or outdated project information can turn duct pricing into a list of assumptions, exclusions and provisional allowances. A commercial ductwork quote is more useful when we receive coordinated drawings, technical requirements and clearly allocated responsibilities. For commercial builders, mechanical contractors and project managers, that preparation makes prices easier to compare and reduces avoidable clarification during procurement.

What Information Should Builders Send for Pricing?

Builders should send the latest mechanical documentation and state exactly which work they want priced. Consultant drawings may show design intent without being ready for workshop fabrication, so the request should identify who handles detailed coordination, site measurement, shop drawings and approval before manufacture. Victorian tender-documentation guidance also supports providing sufficiently detailed drawings, specifications and project-risk information.

• Current documents: Mechanical plans, elevations, sections, schematics, specifications and revision identifiers
• Measured scope: Duct schedules or bills of quantities showing dimensions, quantities and system references, including fittings, dampers and accessories
• Coordination information: Architectural, structural, reflected ceiling and fire-services drawings affecting proposed routes and available ceiling clearances
• Project controls: Site address, nominated contact, pricing stage, submission deadline, construction dates and anticipated contract-award date
• Documentation duties: Required shop drawings, approvals, models, as-built documents and file formats
• Site verification: Confirmation of who checks dimensions, assesses existing conditions and signs off later changes

Define the Technical and Commercial Scope Before Pricing

The request should identify each system as supply, return, outside air, general exhaust, kitchen exhaust or smoke-control ductwork. Provide sizes, routes, levels, air quantities, operating pressure and any leakage-testing requirement specified by the mechanical design. Nominate the material, grade, thickness, finish, insulation, acoustic lining, weather protection and fittings required for the project’s commercial ducting.

Scope boundaries matter as much as dimensions. State if the commercial ductwork quote covers fabrication only, supply and delivery, or supply and installation, then allocate responsibility for supports, penetrations, flashing, fire stopping, dampers, grilles, testing and certification. Identify the applicable NCC edition, Australian Standards and project specification instead of leaving us to assume them.

Coordinate Programme, Access and Delivery Requirements

Before pricing, confirm duct routes are coordinated with structural, electrical, hydraulic, fire and ceiling services. For retrofits, verify dimensions, access, clearances and retained services. Also identify delivery, lifting, packaging, storage and site handling requirements, as these can affect cost, sequencing and safety.

Any unresolved item should be recorded as an assumption or exclusion rather than hidden inside a lump-sum price.

• Approvals: Shop-drawing submission, review and release dates
• Production: Manufacturing release and required completion dates
• Delivery: Staged floor or zone deliveries and required arrival dates
• Access: Loading areas, truck clearances, working hours and storage space
• Handling: Hoists, cranes, unloading equipment and responsible parties
• Staging: Floor access, ceiling closure dates and coordination with other trades
• Site requirements: Inductions, permits, safety procedures and access contacts

Metcon Steel and a Clear Commercial Ductwork Quote

Clear documentation allows Metcon Steel to assess the requested fabrication, materials and delivery or installation scope against the information supplied. We recommend issuing the current document set, identifying unresolved items and checking written qualifications before comparing submissions. This creates a more transparent basis for assessing price, scope and programme while recognising that later design changes may still affect the work.

But to maintain the functionality of air conditioning systems, their overall efficiency must be retained first. Different components can be added to ensure their efficiency. The thermostat, for instance, helps them operate smartly by detecting the surrounding temperature and determining if they must turn these systems on or not. Line set covers can also be added to air conditioning systems, especially on their unit lines, pipes, or wires.

We, at Metcon Steel, offer line set covers that can be perfect for retaining the efficiency and effectiveness of your air conditioning system. Here are some advantages of obtaining line set covers from us at Metcon Steel.

Maintains Efficiency

One advantage of installing line set covers from Metcon Steel is they can maintain the efficiency of your air conditioning system. Our line set covers are fabricated from energy-efficient materials, which can help minimise heat loss in your system. Without these components, your unit lines may end up leaking the cool air outdoors, which then forces your system to produce more cool air and consume more energy until its components break down and deteriorate. You may also be surprised at how costly your energy bills would be.

Prolongs Service Life

Related to the previous advantage, installing line set covers from Metcon Steel can be advantageous for your air conditioning system as it can prolong its service life. Assuming that you always inspect, clean, and maintain the said system, you can expect its service life to extend once you install line set covers from us. Aside from preventing any leakage, our line set covers can also extend the service life of your system as they protect its cables and wires from the effects of heat, moisture, and other damaging outdoor elements.

Inhibits Pest Damage

Aside from damaging outdoor elements, the installation of line set covers from us at Metcon Steel can likewise protect your air conditioning damage from pest infestation and damage. Pests like rodents and bugs, as well as wild animals, might gradually damage the wires, cables, and pipes that may be situated outside your property. Without any covering, these components may get damaged entirely, leading to unnecessary repairs and expenses. Opting for line set covers deters them from causing damage to your system components.

Improves Appearance

One more advantage of installing line set covers from Metcon Steel is they can improve the overall appearance of your property. Pipes, cables, and wires can be commonly attached to the sides of your building. And while they are important in maintaining the functions of your air conditioning system, they can somehow ruin the overall appeal of your property. By covering them with line set covers, you can somehow conceal them uniformly by using the same materials and colours. Doing this can then improve the appeal of your property.

One of these components is the return air vents. Return air vents are system components that aim to pull out air from indoor spaces and deliver it to heating and cooling units. These vents normally do not maximise louvres, unlike supply air vents that often utilise louvres or slats, allowing property owners to direct the airflow.

The Significance of Installing Return Air Vents

The return air vents, which feature return air plates, are necessary for HVAC systems due to a lot of reasons. Some of these reasons are the following.

• Ensure Excellent Air Quality: One of the reasons why return air vents are vital for HVAC systems is they can ensure excellent air quality. Dust particles, allergens, and other contaminants can easily enter the premises of commercial or industrial buildings as some of their rooms remain open. As these elements enter, they can gradually ruin the air quality inside these properties, causing some people to get sick. The existence of return air vents ensures that the indoor air will be filtered and processed optimally.

• Maintain Optimal Air Pressure: Another reason why return air vents are necessary for HVAC systems is they can maintain the optimal air pressure of a building. As the return air vents pull in the indoor air, they subsequently help in sending it to the system. This process helps in maintaining an optimal level of air pressure inside the building, which can minimise structural damage and prevent moisture penetration and condensation.

• Minimise Energy Expenses: One more reason why return air vents must be installed alongside HVAC systems is they can minimise the energy required by the system components. The air is processed optimally once return air vents are installed properly. Of course, energy consumption is also optimised if the ductwork does not have any leaks.

Custom Fabricated Parts Offer More Benefits

The installation of return air vents can already provide tons of benefits to buildings. However, if you are currently managing a commercial or industrial building, you can attain more benefits once you go for custom fabricated return air vents and return air plates.

One advantage of maximising custom fabricated return air vents and return air plates is they can fit the spaces intended for them. Custom fabrication enables these parts to be designed based on the qualities of the building and the HVAC system. Upon obtaining the size of your space, the number of occupants, and other key factors of your property, fabricators can produce custom return air vents and return air plates that can accommodate these elements.

Another advantage of custom fabricated return air vents and return air plates is they tend to last for a long time. Custom fabrication allows you to obtain these parts made from durable materials. Unlike stock return air vents and return air plates, you have the option to pick the materials that will be used in creating them. They may be expensive, but the return on investment with these components is much higher than opting for the stock ones.

Reliable custom support is also granted with custom fabricated parts. When you need custom-fabricated return air vents and return air plates, you can contact us at Metcon Steel.

Many industries take advantage of this process as it can generate high-precision parts. Since sheet metal fabrication utilises computerised and automated machines, parts are expected to boast precise dimensions at specific tolerances the industries would need. Sheet metal fabrication can also accommodate customised designs at high capacity, providing industries with plenty of products in a short time.

Even though sheet metal fabrication guarantees tons of products with precise dimensions, custom shapes, and modern finishes, fabricators should still practice quality control.

The Principles of Quality Control

Quality control in sheet metal fabrication is carried out by performing numerous activities that would measure the products against common standards. The standards set for sheet metal fabrication aim to maintain the quality of consumer goods and manufactured parts needed by businesses in various fields and industries.

Fabricators can only provide quality products to their clients if they will always practice quality control. After all, it serves as the basis for standards compliance, cost reduction, safety, and other crucial elements of their operations and their expected products.

For consumers and clients, the existence of stringent quality control in a fabrication plant means that they can expect a better return on investment on the fabricated components.

Quality Control Main Advantages

Quality control in sheet metal fabrication can provide tons of advantages. Some advantages of quality control are as follows.

• Generate Quality Products: Since quality control covers the selection of metal materials, fabricators can conveniently opt for the best ones so they can also produce quality products. When selecting the materials, fabricators carry out numerous checks, inspections, and tests just to make sure that they choose the right ones. Upon choosing the materials, quality control practices are still maximised so that the fabricated products can boast the needed specifications and perform optimally.

• Ensure Consistency: Quality control does not only deal with material selection, but it can also cover the manufacturing process itself. And so, fabricators are set to follow a set of standards in carrying out the fabrication processes, making sure that clients can expect similar consistent products throughout their service. These standards can make every fabrication project possible, even those with complex requirements.

• Minimise Risk and Hazards: Another advantage of quality control in sheet metal fabrication is it can minimise risk and hazards for fabricators assigned to key projects. Quality control entails the regular checking and testing of the machines and tools used for the fabrication project. Once defects or issues have been detected, these equipment pieces would have to be subjected to repairs before they can be used again. Quality control also involves fabricators undergoing some training on safety practices to lessen making mistakes.

• Reduce Expenses: One more benefit of quality control in sheet metal fabrication is it can reduce expenses. The number of errors during the fabrication process is expected to lessen since quality control practices are expected to be followed. And since products are expected to boast no defects, the chances of the products getting returned to the shop are reduced significantly, which can diminish revenue loss.

These reasons are enough for metal fabrication shops to continue expanding and improving their core fabrication services. Some shops have even incorporated modern technology in converting metal sheets and plates into useful parts and products.

We, at Metcon Steel, have been in the sheet metal and fabrication industry for more than three decades. And by integrating computer numerical control (CNC) machinery, we can easily turn numerous metal materials into products needed for various properties. Here are some metal materials that we can fabricate through CNC machinery.

1. Steel

One of the metal materials that we process with CNC machinery is steel. It is comprised of iron combined with a few amounts of carbon, helping the material attain some improvements in its strength and fracture resistance. Some notable mechanical properties of steel include low weight, dependable durability and ductility, great strength, and enhanced corrosive resistance. As for its applications, steel is highly useful for generating products for the construction, automotive, military, shipbuilding, electronics, and transportation industries.

2. Stainless Steel

Stainless steel is another metal material that our team processes. It has chromium, nickel, and other elements that make it resistant to corrosion and other damaging elements. Through the existence of chromium, stainless steel generates a firm, self-repairing film on its surfaces that makes it durable and long-lasting. Stainless steel can be used in making industrial pipes, tools, turbine blades, boiler parts, and building materials.

3. Zinc

Zinc is a metal material that can be found in the Earth’s crust. This material can be utilised to galvanise steel, protecting it from unwanted corrosion. Compared to other metal materials, zinc is known to be less durable, which deters industries from using it in load-bearing applications. It even has low toughness. One thing that makes this material useful is it has great electrochemical properties. These qualities make it helpful for primarily galvanising other metals, which can be processed to generate products for electrical and hardware industries.

4. Aluminium

Aluminium may have been discovered late compared to other materials, but it has changed the manufacturing industry thanks to its recyclability. Extracted mainly from bauxite that contains 50% alumina, aluminium is currently known to be one of the most abundant metal element in the world. With aluminium’s high thermal conductivity, excellent corrosion resistance, and great formability and machinability, machining companies can easily process it into kitchen tools and utensils, benches, packaging, vehicle chassis, and aircraft parts.

5. Copper

Copper has been around for centuries. After all, the tools and weapons used by early humans were made from this specific material. One feature of copper that makes it useful for industries is it is durable. It is also antimicrobial, which prevents its surface from getting infiltrated by germs and bacteria. This material is likewise known for its excellent electrical and thermal conductivity, ductility, versatility, corrosion resistance, and recyclability. All these qualities make copper useful for creating heating materials, pipes, wires, and cookware.

Take note, however, that not all metals being produced by metal fabrication companies boast the same properties and qualities. Some may need to possess a specific component before they can be converted into a useful part or product. Others, alternatively, have to acquire a particular thickness so that they can be processed further successfully.

The dimensions of metal can affect the outcome of a specific part or product. Without acquiring the right metal qualities, it would be difficult for the industries to attain their needed parts. Two metal types that are being maximised nowadays are metal sheets and metal plates.

Metal Sheet

A metal sheet is a type of metal fabricated into thin, flat workpieces. This metal type is often made by subjecting a hot slab of metal to a series of rough rolling stands. These tools help in making the metal sheet thin and long. Now, to make a metal sheet even thinner, it is often passed into finishing rolling stands, cooled, and ultimately rolled into coils. Usually, a metal sheet can boast a thickness of around 0.55 to 6mm.

What is great about metal sheets is they can be processed further by various metalworking processes. By bending and cutting them in various shapes and dimensions, industries can obtain their needed parts and products without any issues. Metal sheets can also be made from varying metal materials. Some materials that can be turned into sheets are aluminium, copper, brass, titanium, steel, nickel, and tin.

Some applications of metal sheets include architectural materials, electrical enclosures, holding tanks, car components, appliances, packaging materials, and decorative components.

Metal Plate

Compared to a metal sheet, a metal plate boasts a thickness of more than 6mm. As the metal plate becomes thick, it is also expected to become more durable and sturdier. Some metal materials that can be used in creating metal plates are aluminium, steel, and copper.

Metal sheets, as mentioned earlier, come from a hot slab of metal that is further processed by roughing and finishing rolling stands. The rolling process makes the metal sheets sturdy and gains additional strength. Afterwards, the metal sheets are then stacked and compressed together. The compression of these metals generates a single piece of metal plate, which can be processed further through burning or cutting.

What is great about metal plates is they can be used for parts and products in the food processing and construction industries. Metal plates can also be used in creating structural components and parts of heavy machines. The aerospace and automotive industries can likewise benefit from metal plates given their overall durability.

Knowing the difference between metal sheets and metal plates can help business owners like you understand which of them can fit best with your intended applications. Of course, you must also consider the metal materials you will be using to make your project successful. To know more about these metal types, you can contact us at Metcon Steel.

Proper storage of foods and drinks is necessary as they can be sensitive to a lot of things. When stored ineffectively, they end up getting spoiled very quickly. Once they are spoiled, restaurant managers or owners do not have a choice but to replace them, which can cost them more money. A well-ventilated kitchen environment is also necessary for restaurants to ensure that their cooking processes will not negatively affect the health of employees as well as the quality of their finished products.

At Metcon Steel, we understand these restaurant needs. Hence, we offer elements necessary for the betterment of these establishments. If you want to improve the state of your restaurant, here are some elements we can offer you through our fit-out services.

Coolrooms and Freezers

Coolrooms and freezers are cold storage units that can preserve the quality of food products. What is great about our coolrooms and freezers is they are made from quality metals and other components that can prevent heat from infiltrating the interiors. As they deter heat, all raw food ingredients inside are expected to retain their nutrients, flavour, texture, and other notable qualities. Their aging process is likewise slowed down to make sure that they can still be utilised once they are up for consumption. With these cold storage units, you can minimise food wastage and expect more revenue.

Extract Canopies and Range Hoods

Your restaurant kitchen is guaranteed to be always busy even before the start of your operating hours. As your employees cook different types of meals on your menu, this place will certainly be bombarded with grease, smoke, odours, and other pollutants from the cooking processes. These things may signify that your kitchen is truly busy, but they should be removed from the air right away to prevent health effects. Fortunately, our team at Metcon Steel can design and craft extract canopies and range hoods that can effectively remove these things from your kitchen air.

Fire-Rated Stainless Steel Splashbacks

Grease does not only ruin the air quality of your kitchen. It can also stick on your walls after cooking many meals in a day. While it can be cleaned with the right cleaning tools and products, it can certainly take some time just to remove it. However, by installing splashbacks on your kitchen walls, you can conveniently remove them by wiping them with a cloth and a cleaning solution. Many materials can be utilised in making splashbacks. But at Metcon Steel, we opted for fire-rated stainless steel to ensure that they can deter grease and grime build-up and consequently resist heat and fire.

Steel Shelving and Racking Systems

Two more elements your restaurant should possess are steel shelving and racking systems. Shelving and racking systems are crucial for your restaurant operation since they can help organise and store your food ingredients, cooking tools, and even devices for cooking processes. And since we offer them in steel, you can be assured of storage solutions that are hygienic, durable, appealing, and long-lasting.

To gain access to these things, you can contact us at Metcon Steel.

Most restaurant owners already know the essence of investing in various cooking equipment pieces in their respective kitchens. Some of them, however, ignore the significance of storage and safekeeping. Without investing in proper storage equipment, their commercial kitchens end up getting cluttered and messy. The productivity and efficiency of their employees may also drop since they will not be able to access and find their needed items right away.

To prevent these things from happening, you must equip your restaurant kitchen with steel shelving. Here are some reasons why this type of shelving can be good for your business.

1. Enhanced Organisation

One reason you must add steel shelving in your restaurant kitchen is it can enhance the organisation of your kitchen items. Your restaurant kitchen may already be filled with cabinets and drawers for various kitchen tools and equipment. But sometimes, these storage spaces can get crowded, especially during busy days. By acquiring steel shelving, you can enhance the organisation of your things all the time. You can even make partitions to separate food products from tools.

2. Improved Accessibility

Another reason you should add steel shelving in your kitchen is it can improve the accessibility of your things. Some food items can already retain their freshness despite storing them at room temperatures. As you add steel shelving, you can now use it to store these kinds of foods. Not only they will be organised properly, but they can also be accessed right away by your employees. Your employees can also access cooking tools and equipment conveniently once you store them on the shelving.

3. Boosted Customisability

The main purpose of adding steel shelving to your kitchen is to gain additional storage space for your food products and kitchen tools. An additional storage space, however, might not be effective if it does not match your needs. Fortunately, steel shelving can be customised based on your preferences. If you want to protect your items from dust, you can opt for a closed steel shelving. Otherwise, you can go for an open steel shelving to display tools often utilised during your kitchen operations.

4. Guaranteed Durability

One more reason why you must add steel shelving to your kitchen is it can help your business for a long time. Steel shelving units are known for their durability, allowing heavy items to be stored without obtaining any damage. They can also withstand wear, tear, extreme temperatures, rust, oxidation, and other elements that can easily damage other types of shelving. All the strength and durability of steel shelving make it a great investment for your restaurant.
