Sheet metal fabrication is the art of forming metal into flat and thin pieces that can be cut and bent into various shapes.
Many heating, ventilation, and air conditioning HVAC companies use custom sheet metal fabricators to create ductwork with custom specifications. Creating everything from air ducts to plenums to brackets for HVAC systems is definitely a customized necessity since each HVAC system is different in measurements and needs.
Quality metal ductwork is essential for efficiently distributing conditioned air throughout New Jersey homes and buildings. Your indoor air quality (IAQ) and comfort depend on quality ductwork. Call Delco Air today to speak with one of our certified technicians about how custom sheet metal fabrication can be a durable, cost-effective solution for you.
Delco Air is a trusted name for providing reliable products and services to homes and businesses in Old Bridge, NJ, and the surrounding communities. Call us today for a free consultation about your next project.
Sheet Metal Fabrication Basics
Custom-fabricated sheet metal typically comes in rectangular sheets or, if they’re thin and long, rolls. Sheet metal also comes in varying degrees of thickness.
HVAC systems dictate specific industry standards of thickness for various parts of the ductwork, but the majority of dictates fall into the 6 mm range.
Sheet metal forming is a grouping of several processes, working together in a complementary manner to form the needed parts. One or more of these processes mechanically applies deformation forces changing the shape of the metal. Custom fabricators create ordered HVAC pieces by cutting and forming the flat sheet metal into various shapes, then finishing each piece.
Here are the metals commonly used in sheet metal fabrication:
Aluminum
Carbon Steel
Stainless Steel
Copper
Titanium
While carbon steel is one of the most widely used metals in sheet fabrication, our team can help you determine the best metal to complete your design requirements. Schedule your appointment today to go over your project.
Be sure to ask about our convenient financing plans tailored to your needs and budget.
Sheet Metal Processes
A custom order can begin with an engineering drawing, a hand drawing, or even a phone call with the needed measurements. All specifications, particularly the measurements, are clarified before the project goes to the cutting, forming, and assembling stages:
Cutting is the act of cutting sheet metal into smaller shapes that are used later in the fabrication process.
The drawing process relies on a mold or dies to form the sheet metal into the desired shape.
Folding bends the sheet metal to certain angles.
Sheet metal punching creates holes in the sheet metal.
Sheet metal shearing cuts sheet metal into a long straight line.
Sheet metal stamping is similar to punching but does not completely cut through the metal.
Roll forming turns sheet metal into a rounded shape.
Assembling is joining the cut and formed pieces.

EXCELLENT Based on 102 reviews Scott Forgue2025-01-24Trustindex verifies that the original source of the review is Google. We called Delco Air due to the heat not working in our student housing property on one if the coldest days. They sent a tech over within a short time and resolved the problem to get the heat working. The tech also provided a small list of items that need to be addressed to prevent future problems. The cost was more than reasonable and we recommend anyone to use them.

Karina Z2025-01-12Trustindex verifies that the original source of the review is Google. I recently had the pleasure of working with Delco Air to replace my aging furnace, and I couldn’t be more impressed with their service from start to finish. From the moment I reached out for a quote, their customer service was top-notch. The team at Delco Air was friendly, professional, and thorough in explaining the options available for a new furnace. They took the time to assess my home’s heating needs and helped me select the perfect system for both efficiency and comfort. I appreciated their transparent pricing and no-pressure approach. I was fortunate to have Ryan doing the work and he was knowledgeable, professional & efficient. The installation was seamless. The technicians arrived right on time, and they were incredibly courteous throughout the entire process. They protected my floors and furniture, removed the old furnace, and installed the new system without any issues. They even took the time to walk me through the new unit, explaining how to use it and offering maintenance tips to keep it running efficiently. Since the installation, my home has been warmer, more comfortable, and more energy-efficient. The new furnace heats the house evenly, and I’ve already noticed a decrease in my heating bills. It’s also much quieter than my old system, which was a pleasant surprise. I can’t recommend Delco Air enough! Their professionalism, expertise, and commitment to customer satisfaction are truly exceptional. If you’re considering furnace replacement, don’t hesitate to give them a call—you won’t be disappointed! Nestor Negroni2025-01-11Trustindex verifies that the original source of the review is Google.

The company I used in the past were not able to service my furnace because they did not have any parts in stock and they are a carrier repair service. I called Delco and spoke to the service manager Mark and they were able to locate the part in minutes. They sent their service tech out, Ryan and he had heat back on within 30 minutes. Thanks to the Delco team for a quick response and excellent service. I know who I will call going forward.
