The Albina Co., Inc. team recently spiraled a true HSS stair stringer to a very tight configuration for a spiral staircase project in Washington. The project consisted of using an induction heat source, on our custom made bending equipment, to spiral bend tube steel 16" X 12" X .625" WALL A500 GR B the easy way to a 77” Center Line Radius. VERY TIGHT and VERY IMPRESSIVE! Great work team!
