ERW Pipes (Electric resistance welded) are construct from steel coil with a parallel weld seam. There is a limit to the diameter of the coil since its width matches the circumference of the pipe.As a result, roofing structures are being construct with them in place of wood. With this ASTM A213, and Astm A335 are also the two best options of pipes.
