Header Flanges

We offer the finest in CNC laser cut header flanges. While most header flanges are made from 1/4" or 5/16" material, our header flanges are precision CNC lasercut from 3/8" material. We offer our flanges in 304 stainless steel or1018 cold rolled steel. The heavier materials we use to fabricate our flangesgreatly reduce the warping problems seen in other lighter flanges. These headerflanges are U.S. made.
