Your Mount Vernon, WA, Sheet Metal Experts.

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 Washington homes and buildings. Your indoor air quality (IAQ) and comfort depend on quality ductwork. Call Beaver Heating & 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.

Beaver Heating & Air is a trusted name for providing reliable products and services to homes and businesses in Mount Vernon, WA, 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.

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.
  • Punching creates holes in the sheet metal.
  • Shearing cuts sheet metal into a long, straight line.
  • 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.

We had Beaver Heating and Air install a new HVAC system….they were exceptionally great to work with, careful with our home, cleaned up everything after they finished and were nice to my barky little dogs, too! It was a wonderful win for us, all around. I’d HIGHLY recommend calling this company for any HVAC needs

WOW!! There are still people in the world who put service over profit! I will be recommending Mason at Beaver Heating and Air to everyone I know. My duplex was without heat, and I had several guys come out and tell me I needed a total furnace replacement totalling $6k or more. Mason came and asked, has anyone tried to figure out what's wrong with it? He figured it out in a few minutes, ordered a replacement motor, and had it installed for just a few hundred. His attitude and friendliness is so refreshing and nice to be around, and I immediately could tell that I could trust him. He said he has 9 years of experience, and it showed! I would never use anyone else but him going forward! AAA++++++++

We needed service on our water heater and found beaver heating & air through Rheem’s “find a pro” option on their website. Mason was very friendly and knowledgeable. He was able to efficiently replace a part on our Rheem water heater. We would recommended Beaver heating & air and will use them again in the future.If you are considering any HVAC upgrades or additions, consider reaching out to Beaver Heating and Air. You won’t be disappointed!
