Carbon Steel Plate
Our versatile carbon steel sheets meet the diverse needs of industrial and infrastructure projects, encompassing a range of grades to satisfy specific load-bearing, weldability, and corrosion resistance requirements—including low-carbon steel (Q235B, A36, 1018), medium-carbon steel (Q355B, 1045, A572 Grade 50), and high-strength low-alloy steel (HSLA). Low-carbon steel grades offer excellent weldability, formability, and cost-effectiveness, making them ideal for general structural applications such as building frames and machinery bases; medium-carbon steel grades balance tensile strength (up to 600 MPa) and machinability, suitable for load-bearing components such as gears and hydraulic parts; high-strength low-alloy steel grades (e.g., Q355B) incorporate microalloying elements such as manganese and silicon, increasing yield strength without sacrificing ductility, making them ideal for heavy engineering projects.

Customizable Specifications: Thicknesses ranging from 2 mm (precision cold-rolled sheet) to 200 mm (heavy-duty hot-rolled steel sheet), with standard sizes up to 3000 × 12000 mm. Custom cutting, chamfering, and drilling services are available to improve on-site assembly efficiency.
All steel sheets undergo rigorous manufacturing processes—strumental grade sheets are hot-rolled (refining grain structure through controlled cooling), while precision sheet sheets are cold-rolled (ensuring thickness tolerances of ±0.02 mm). Optional surface treatments such as shot peening, primer, or galvanizing are available to enhance rust resistance in outdoor or humid environments.
Beyond their core advantages (cost-effectiveness, high tensile strength and toughness, and versatility in processing), these steel plates play a fundamental role in key sectors: construction (high-rise steel frame structures, bridge decks, foundation piles), machinery manufacturing (agricultural equipment housings, industrial stampings), pressure vessel manufacturing (low-pressure storage tanks, pipeline sections), automotive (truck chassis, trailer frames), and energy (coal-fired power plant boiler supports, wind turbine tower flanges).
✅
Compliance & Quality: All products comply with GB/T 700, ASTM A36, ASME SA516, and EN 10025 standards. Each batch undergoes ultrasonic testing, tensile testing, and hardness (HB/HRB) testing to ensure structural integrity.
