We recently finished up some Tube Steel ¾" X ¾" X .065" WALL 6063-T52 ALUM bent into a double 90° configuration to a 3¼" inside radius. These curved steel parts will be used for seat frames on small airplanes. We do a number of parts for the aviation and aerospace industries including hydraulic lines, exhaust lines, exterior structural parts and interior support elements like the seat frames pictured below.
