Our hot rolled carbon steel plate, available in grades Q235, Q355, Q420 and Q460, is one of our best-selling structural steel products.
It is produced through strict hot rolling procedures: after continuous casting, the steel billets are heated under controlled high temperature, then rolled repeatedly by heavy rolling mills to achieve uniform thickness and flat surface. The whole production process follows national and international standards, with online dimension monitoring and mechanical property testing to guarantee consistent quality.

This series steel plate boasts balanced mechanical properties. Q235 offers excellent plasticity and easy weldability; Q355, Q420 and Q460 deliver progressively higher yield strength and great load-bearing capacity. All grades feature good cutting, bending and forming performance, convenient for further processing such as laser cutting, drilling and welding.

They are widely applied in multiple industries. For construction field, it is used for building frames, support brackets and workshop structures. For machinery industry, it serves as base plates, equipment housings and mechanical component blanks. It is also commonly used for container manufacturing, road & bridge auxiliary structures, agricultural machinery, transportation facilities and other general engineering projects.

We can provide various thicknesses, widths and lengths as your requirement. Custom cutting service is supported. Every batch will go through strict inspection before shipment, including chemical composition analysis, tensile test and impact test. With factory direct supply, competitive pricing, stable stock and flexible delivery terms, we can meet different project demands from worldwide customers.
