A36 Carbon Steel Plate

ASTM A36 / A36M structural plate, the standard US designation

A36 Carbon Steel Plate

A36 is the most widely used structural steel in the Americas: 250 MPa minimum yield, 400–550 MPa tensile, good weldability and a composition band that leaves room for field fabrication. It is the grade most Latin American fabricators write on their drawings, and it is quoted against S235JR, SS400 and Q235B. We supply plate with the mill certificate stating A36, plus the equivalent designation if your inspector asks for it.

How to choose

A36 is the safe default for general structural plate. For higher strength use A572 Gr.50 or S355JR; for low-temperature service step to A516 Gr.70 or A350 LF2.

FAQ

Does A36 plate come with ASTM-compliant certification?
Yes. The certificate states ASTM A36/A36M with heat number, chemical composition and mechanical tests. If your project requires an independent inspection, we arrange SGS, BV or Intertek before loading.
What lengths can you supply?
Standard 6000 mm and 12000 mm, or cut to your list. Thickness 3–200 mm, width up to 3200 mm.
