Application Domain

  

Our various steel plates are widely applicable in construction, bridge engineering and machinery manufacturing fields. Conventional carbon steel plates like Q235B and ASTM A36 are ideal for building steel structures, bridge components, factory frames and municipal engineering projects with stable load-bearing capacity. High-strength carbon steel plates, wear-resistant steel plates and 65Mn spring steel plates are commonly used for machine bases, equipment shells, automotive accessories and mechanical stamping parts, supporting multiple deep processing technologies such as welding, bending and stamping to meet diverse mechanical manufacturing needs.
Special functional steel plates cover more professional industrial and commercial scenarios. Stainless steel plates feature excellent corrosion resistance, suitable for petrochemical equipment, pressure vessels, food processing machinery and water treatment facilities. Galvanized steel plates are widely used for environmental protection equipment, ventilation systems and electrical cabinets for their superior rust-proof performance. Corten weathering steel plates are the preferred material for outdoor landscape sculptures, architectural curtain walls and garden decorations. In addition, professional bulletproof steel plates are specially applied to security protection equipment and special defense engineering, meeting high-standard safety protection requirements.
