        Definition: direct-delivery coils are cut or recoiled after end cutting, tail cutting, edge cutting as well as multi-times straightening, leveling and other finishing line treatment processes, to form hot-rolled steel plates, level hot-rolled steel coils, longitudinally-cut strips and other products.

        Materials: Q235, 345B, etc.

        Specifications: 1.5m width, customizable length

        Packing: packing according to customer requirements

        Types & Applications:

        1>Structural steel
        Which is mainly used for producing steel structural parts, bridges, ships and vehicles

        2>Weather-resistant steel
        By adding special elements (P, Cu, C, etc.), weather-resistant steel has good corrosion resistance and atmospheric corrosion resistance, and is used for producing containers and special vehicles, and also applied to structure buildings.

        3>Automobile structure steel
        High-strength steel plates with good stamping performance and welding performance are used for producing automobile FRAME, WHEEL, etc.

        4>Hot-rolled Special Steel
        Carbon steel, alloy steel and tool steel for general mechanical structures are used for producing mechanical parts after heat treatment engineering.

        5>Cold-rolled Original Plate
        It is used for producing various cold-rolled products including CR, GI, color-coated plates, etc.

        6>Steel Plate for Steel Pipe
        It has good processability and compressive strength, and is used for producing high-pressure gas pressure vessels which have the inside volume of less than 500L and are filled with LPG, acetylene gas and various gases.

        7>Steel Plate for High-pressure Vessel
        It has good processability and compressive strength, and is used for producing high-pressure gas pressure vessels which have the inside volume of less than 500L and are filled with LPG, acetylene gas and various gases.

        8>Stainless Steel Plate
        Stainless steel has good corrosion resistance, and is mainly applied to food industry, surgical equipment, aerospace, petroleum, chemicals and other industries.
