Product Overview
ASTM A36 Steel Plate is the industry-standard low-carbon steel plate for structural and general engineering applications. Manufactured to ASTM A36/A36M standards, it delivers a reliable minimum yield strength of 250 MPa (36 ksi) alongside high weldability, clean machinability, and easy forming.
Widely specified for commercial construction, bridges, heavy machinery, and equipment frames, ASTM A36 offers the market's most cost-effective balance of structural strength and practical workability.

International Equivalent Grades
To help you match local project requirements, ASTM A36 is generally equivalent to the following international standards:
Europe: S235JR / S235J0 (EN 10025)
China: Q235B / Q235C (GB/T 700)
Japan: SS400 (JIS G3101)
Key Advantages
Fully complies with ASTM A36/A36M standards, delivering a minimum yield strength of 250 MPa (36 ksi) for reliable structural load-bearing.
Keeps carbon content at or below 0.25%, ensuring excellent weldability without the need for preheating under standard conditions.
Maintains an elongation rate over 20%, offering great flexibility for cold-bending, machining, and forming without cracking.
Processed through heavy-duty roller levelers for superior flatness. This drastically reduces the risk of torch height control (THC) jamming or nozzle damage during high-speed CNC plasma or fiber laser cutting.
Custom Processing Capabilities
Precision Flame/Plasma Cutting: Custom profile cutting based on customer drawings. Cutting tolerances can be controlled according to project requirements and plate thickness.
Weld Joint Beveling: Professional preparation of welding joints (including V-groove, X-groove, and Y-groove) to save your labor and fabrication time on-site.
Drilling & Punching: Multi-hole custom drilling for base plates, connection flanges, and structural gussets.
Supply Capacity & Logistics Risk Control
Monthly Output: 15,000 Metric Tons. Standard dimensions are consistently stocked, enabling rapid dispatch within 7–14 days.
Third-Party Inspection: We fully welcome and cooperate with SGS, BV, or Intertek for on-site visual, dimensional, and lab testing prior to loading.
Sea Freight Packing: Heavy-duty steel strapping, waterproof paper wrapping, and edge-protection brackets. All plates receive an anti-corrosion coating to prevent seawater rust during transit.
