About Duct Connections

Duct Flanges
Bolt flanges to equipment to start a run of duct. They can also create secure connections between two duct ends by mounting a flange to each end and then joining the flanges.
Steel, galvanized steel, and 304 stainless steel flanges are also known as angle rings.
Galvanized steel flanges have good corrosion resistance. Aluminum flanges have good corrosion resistance in wet environments, and weigh less than steel and stainless steel flanges. 304 stainless steel flanges are more corrosion resistant than steel.
