Extremely Tight Tube Steel Spiral Stringers for Lakeside Campus Building Staircase

Enjoy the latest install pictures of the 20” x 8” x .625” wall tube steel which provides the base supports for a heavy weight bearing spiral staircase at the Lakeside Campus in Richardson, Texas. 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 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, but Albina was able to do it to perfection!
