Angle Flanges

Steel angle rings are used widely in joining ductwork together in different applications. 3" to 96" diameter flanges available. Angle rings 3"-5" are pressed and 6" and larger are rolled from structural angle iron. Rolled rings allow perfect fitment on your pipe reducing air leakage, reducing the valley for moisture to sit and leak through, and are tougher rings that can withstand more abuse. Rolled rings also make vanstoning easier, eliminate harbors for germs or debris to build up, and eliminate the need to "dress" duct to the ring by pounding with a hammer to eliminate gaps. Each ring is electronically measured and recorded to ensure proper diameter and are punched on state-of-the-art computer controlled equipment to ensure burr free holes (including holes on the easy way leg).

*Rings stocked in black iron. Custom rings in Carbon Steel (A36), Stainless Steel (304 and 316), Aluminum, Hot Dipped Galvanized with a coating specification of ASTM A123, Electro-plated rings (corrosion protection adhering to ASTM B633 type iii) available upon request with short lead times. Rolled 4" and 5" flanges available as special order items.

Plate Flanges


Cast aluminum cut-offs with galvanized steel slide gate. Cut-offs are used to balance systems, or save air, heat and power when a machine is not in use. The collar of the whole gates are tapered to allow for a tolerance on the exact diameter of the duct. Half gates are usually used in a retrofit of a system where a 180 degree section is cut out of the duct and the collar is intended to straddle the duct. All cut-offs are furnished with set screws so the blade may be firmly placed for volume control. Custom fabricated gates are available in carbon steel, stainless steel with rolled collars or angle rings.

Stocked sizes include 3" through 14" diameter (half and full). All sizes 2” to 22” diameter (half and full) we can source for you factory direct.
