HVAC Sheet Metal Supplier

Galvanized Coil and Sheet Steel Supplier

One of the primary industries we serve is the HVAC industry.  Every HVAC system is comprised of air ducts, or duct work, which can be made with slit steel coil or steel sheets. Quality metal ductwork is essential for an efficient distribution of heated or cooled air throughout residential or commercial buildings. We can provide the slit steel coil or sheets to make the metal ductwork. 

From equipment manufacturers to small service companies, Curtis Steel has been committed to serving the HVAC industry for over 40 years.  With coil and sheet stock sizes in 36”, 48”, and 60” widths, we strive to maintain the sizes you need for immediate pick up or delivery.  In addition, spiral pipe coils, hanging strap coils, turning vane coils, and coils for automatic duct lines are kept “on the floor”. We can produce custom sizes to reduce waste, and can even supply “beaded” sheets if necessary.  Whether you need a few sheets or a few truckloads, our experienced sales team stands ready to assist you. Contact us today for your HVAC needs!

With over four decades of processing experience under our belt, our experienced, quality focused operators are ready to produce orders to your exact specifications!

Why use galvanized sheet metal for HVAC system design?

Fabricated sheet metal allows metal to bend into the desired shape. This allows individual pieces to fit together. The thick solid wall makes ducts very durable. In addition to using galvanized steel for building ducts, the materials zinc coating helps prevent corrosion and rust buildup in HVAC systems.
