ASTM A36 is a standard material specification for carbon steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes. This specification covers chemical and mechanical and other supplementary requirements for carbon steel bars, plates and other structural shapes. Boltport stocks and uses ASTM A36 bars and plates to manufacture bolts, screws, studs to ASTM A307 Grade A, F568M Class 4.6, ASTM A325/A325M Type 1, Anchor bolts and rods to ASTM F1554 Grade 36, nuts to ASTM A563/A563M Grade A and rivets to ASTM A502 Grade 1 specification.
