    Carbon Steel Plate

    🏗️ Low-Carbon Steel ⚙️ Medium-Carbon Steel 🔩 HSLA Steel ✅ GB/T 700 · ASTM A36 · ASME SA516 · EN 10025

    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.

    Custom Specifications Thickness: 2mm–200mm; Size up to 3000×12000mm; Custom cutting, chamfering & drilling available.
    🔬
    Precision Manufacturing Hot-rolled & cold-rolled options; thickness tolerance ±0.02mm; shot peening, primer, or galvanizing surface treatments.
    🏭
    Wide Application Range Construction, machinery, pressure vessels, automotive, energy — all key sectors covered.

    We offer fully customizable specifications to meet project drawing requirements: 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). All products comply with GB/T 700, ASTM A36, ASME SA516, and EN 10025 standards, and each batch undergoes ultrasonic testing, tensile testing, and hardness (HB/HRB) testing to ensure structural integrity. We provide volume supply, just-in-time delivery, and technical consulting services to support global infrastructure, heavy industry, and manufacturing customers, balancing performance and cost for small-batch precision parts and large-scale construction projects.
