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.
📐 Fully Customizable Specifications: Thicknesses from 2 mm (cold-rolled) to 200 mm (heavy-duty hot-rolled), standard sizes up to 3000 × 12000 mm. Custom cutting, chamfering, and drilling available. Thickness tolerance: ±0.02 mm for precision cold-rolled sheets.
Optional surface treatments — shot peening, primer, or galvanizing — are available to enhance rust resistance in outdoor or humid environments.
Carbon steel plate is a popular choice for various industrial applications due to its strength, durability, and cost-effectiveness. It is made by rolling a block of carbon steel into sheets of different thicknesses, resulting in a material that can withstand heavy loads and extreme temperatures. The carbon content in these plates ranges from 0.05% to 0.3%, making them ideal for welding, bending, cutting, and other fabrication processes. They are available in multiple grades and sizes, allowing you to select the right one for your specific requirements. Whether you need it for construction, automotive, shipbuilding, or any other industry, carbon steel plate is a reliable option that offers excellent value for money.
Beyond their core advantages — cost-effectiveness, high tensile strength and toughness, and versatility in processing — these steel plates play a fundamental role across key sectors.
