Product Description

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.
Carbon Steel Plate Processing
Carbon Steel Sheet Inventory
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.
