Custom Duct Fabrication & Custom HVAC Ductwork

Since the 1920s, Chicago Metal Rolled Products has been providing custom duct fabrication and custom HVAC ductwork, including stainless steel ductwork, to match our customers’ unique specifications.

Ductwork angle rings and fittings have been a core part of our business since that time, as well. In fact, we’ve developed our own line of standard angle rings, with diameters from 3” to 72”. Our angle rings and fittings are key components in ductwork, ventilation, and pneumatic conveying systems.

Custom Duct Fabrication Capabilities

Chicago Metal Rolled Products (CMRP) are the proven experts in custom duct fabrication. We produce custom ductwork from galvanized steel, stainless steel, aluminum, copper, and other alloys, and have developed a line of galvanized lock-seam pipe in 20-, 22-, and 24-gauge, in 10’ lengths and with diameters from 3” to 14”.

CMRP supplies large angle rings to connect ductwork in steel mills, e.g. 4 x 4 x 3/8 angle rolled leg out to 12’ diameter with bolt holes.

Custom Duct Fabrication

CMRP can provide completely custom duct fabrication. Working from your blueprints or specifications, we can produce custom HVAC ductwork or other ductwork components that meet all your application requirements. Contact us to discuss custom duct fabrication.

Duct Fabrication: Value-Added Services

• Your custom ductwork can be fitted with an angle flange on one or both ends to connect it to other sections of ductwork or to connect to equipment like dust collectors
• Ductwork can be connected via Van Stone flanges, wherein the ductwork is flared to create a tight seal where two flanges pull the round cylinders together
• In addition to straight sections, we CMRP can also provide the following fittings and components for your custom duct fabrication: elbows, Ys, tees, reducers, squared-arounds, cones—virtually any shape needed to create a complete duct work system

Ductwork Applications 

Stainless steel ductwork is commonly used in cleanrooms, in food-processing applications, and in hospitals, among numerous other examples. Other materials are used to produce custom HVAC ductwork and custom ventilation ducts, ductwork for pneumatic conveyor systems, and for exhaust vents—along with countless other applications.

The Solo Cup Company in Chicago uses Chicago Metal Rolled Products’ galvanized ductwork to convey the plastic material they use to make their disposable cups The cups are drawn from a large sheet of plastic which is then ground up, conveyed up and across the roof of the plant, then back down to be melted again and made into new sheets.
