Frequently Asked Questions

What is ASTM A36 steel?
ASTM A36 is the most common mild carbon structural steel grade in North America. It has a minimum yield strength of 36,000 psi (250 MPa) and is widely used in general structural applications.
What is A36 steel equivalent to?
ASTM A36 is approximately equivalent to GB Q235B (China), EN S235JR (Europe), JIS SS400 (Japan), and AS 3678 Grade 250 (Australia). These grades have similar chemical and mechanical properties.
What thickness of A36 plate do you supply?
We supply A36 carbon steel plates from 3mm to 200mm in thickness. Widths from 1000mm to 2500mm, lengths from 2000mm to 12000mm. Custom cutting available.
What are A36 steel plates used for?
A36 plate is used in general structural steelwork, building construction, bridges, machinery manufacturing, shipbuilding, pressure vessels (non-code), storage tanks, and plate fabrication.
Can A36 steel be welded?
Yes, A36 has excellent weldability using all common welding methods (SMAW, GMAW, FCAW, SAW). Preheat is generally not required unless thickness exceeds 50mm or ambient temperature is very low.
What's the price of A36 steel plate?
A36 carbon steel plate pricing depends on thickness, size, quantity, and current market conditions. A36 is generally significantly less expensive than stainless steel. Contact us for an exact quote.
Do you supply A36 plate with Mill Test Certificate?
Yes, every shipment includes a full MTC showing chemical composition, mechanical properties (tensile, yield, elongation), and heat number for traceability.
Can you cut A36 plate to custom sizes?
Absolutely! We offer plasma cutting, flame cutting, and laser cutting services to cut A36 plate to your exact drawings and specifications. Small parts or large profiles — no problem.
