ASTM 36 is an American standard carbon structural panel, which implements the standard ASTM A36/A36M-03a. This standard is suitable for riveting, bolting and welding structures for bridges and buildings, as well as structural steel quality carbon steel sections and steel plates for general purposes. And bar steel.
