We Manufacture
Rectangular Duct & Fittings. CSM has been
serving the region
for over 30 years. We are a family owned business started by
my father Lee Vance in 1980. He began as a sheet metal
roofing and architectural metal company and began selling
ductwork after a modernization effort to keep pace with our
workload. We still do installation in our local area so we
are more familiar with the importance of quality and timely
deliveries than some manufacturing only companies. We have
the capacity to produce 15,000 lbs per day on a single shift
and would like to become an extension of your shop. To
assist us we have on site a full range of HVAC forming
equipment to include.
• Iowa Precision 5’ coil line equipped with insulating
• Plasma Table
• CNC Press Brakes
We can fabricate any gauge or pressure class with or without
liner with Pittsburgh seam or Snap Lock in Single wall or
Double wall with Custom Labeling. Delivered as L
–shaped or Full wrap around. We also weld duct
work of all metal materials.
Please call us for quotes on all your HVAC duct needs.
While we manufacture only rectangular we are able to supply
round and Oval Duct as well bought from other
manufacturers. So we can help with all or any part of
your project.
