Rolled Plate Creates Spiral Stair Stringers

Albina Co., Inc. recently rolled steel plate to create the spiral stair stringers for a beautiful custom curved steel staircase in California. The plate sections consisted of 1/2″ x 14″ A36 plate rolled counter clockwise to a 38′ 8″ radius and 43′ 9″ radius. For portions of the landing area, 1″ X 14″ A36 plate was rolled anywhere from a 37′ 7″ radius to a 42′ 6″ radius. Various other structural steel members were bent including 4″ X 4″ X ΒΌ” ANGLE A36 rolled legout to a 37′ 6″ radius.
