Tube Steel Spiral Stringers Provide Support for Heavy Weight Bearing Spiral Staircase

Albina recently bent tube steel 20” x 8” x .625” wall which will provide the base supports for a heavy weight bearing spiral staircase.  The tube steel was spiral bent the easy way using our induction heat source and increment bend method. The tube steel was bent down to a 7’ 7” center line (plan view) radius and all bends were to AESS standards. Albina also bent tube steel 20” x 12” x .625” wall for a different section of the spiral staircase.  The tube steel was spiral bent the easy way also using our induction heat source and increment bend method. The 20" x 12" material was bent down to a 13’ 9” center line (plan view) radius and all bends were to AESS standards. The specifications to bend to a center line radius this tight is almost unheard of! Albina was able to bend per the customers specifications and provide an exceptional quality product!
