Welded Ductwork and Specialty Duct

From Grease Duct to Industrial Welded Duct

Welded Duct from ZEN IndustriesMost duct fabricators can deliver on the basics of rectangular and spiral duct.

When it comes to heavy duty, welded ductwork and specialty pieces made of galvanized, mild steel, cold roll, stainless steel, aluminum, and more, owners, architects, and project managers turn to experienced duct fabricators like ZEN Industries.

In addition to standard HVAC ductwork and fittings, ZEN Industries produces:

  • Heavy gauge welded ductwork
  • Welded roof curbs and exhaust ductwork
  • Grease duct
  • Stainless
  • Aluminum

You can count on ZEN to meet compliance standards too. In North America, grease ducts must be manufactured in compliance with National Fire Protection Association (NFPA), standard 96, as well as all local building and fire codes. Whatever specifications are necessary for your project, ZEN works with you to assure on time, on budget, and on spec performance.

Let’s take a look at some recent photos from our production floor.

Benefits of Stainless Steel Ductwork

Stainless steel makes an excellent choice for ductwork from several viewpoints. While it is  more expensive than galvanized or aluminum, it is increasingly requested by engineers for its unique advantages.

  • Stainless steel boasts extreme durability and corrosion resistance.
  • Greater strength than aluminum with high abrasion resistance.
  • Stainless resists condensation and moisture, giving less opportunity for mold and mildew and resulting in healthier buildings.
  • Useful for both exterior and interior duct configurations.
  • Stainless steel is 100% recyclable.

In situations where HVAC systems must move high volumes of conditioned air, the rigidity and long life of stainless-steel duct make it the superior choice. Stainless is also essential in industrial situations where oil and other fine mists are being drawn out of the air. Finally, the durability of stainless means the HVAC ductwork lasts longer without replacement, lowering lifetime building costs.

Update on Steel Prices

Last month we reported that hot-rolled steel prices showed a decline for the first time in over a year.

The change was small, but steel users seem to think a decline in steel prices is near, with 80% of executives believing hot-rolled steel prices have peaked and that cold-rolled and coated products have achieved flat or declining prices.

At ZEN Industries, we agreed. On the structural side, we have experienced a small pricing decrease, the first since Aug. 2020. The demand is lowering, scrap is lowering, pressure from imports and a consumer base that has had enough price gouging are all leading to lower pricing.

See the Carbon Steel Imports graph accompanying this article. The US has more than doubled imports since Feb 2020.

Carbon Steel Imports

Once the steel pricing went sky high, US manufacturers put in orders for imported steel once they saw that this market was going to last a long time. These orders are now being received, at a much lower price than US produced steel.

So, the competition is back (even with the tariffs, the imported steel is 20-30% less than current domestic), which will put pressure on domestic steel producers to lower costs. The domestic mills want that business that is now going to the international market due to low cost.

At ZEN Industries, we believe these competitive pressues are sure to deliver a cost reduction soon.
