Hot rolled steel plate is a fundamental industrial steel material processed under high-temperature rolling, covering mainstream grades including Q235B, Q235JR, Q355B, Q355JR and Q345B. Classic optimized models includeASTM A36 hot rolled carbon steel plate Q235B for general structural construction and S355JR low alloy high strength hot rolled steel plate for bridge and machinery manufacturing. It features good overall mechanical performance, excellent ductility, weldability and processability. With high structural stability and cost-effectiveness, it is one of the most widely used general-purpose steel plates in global manufacturing and construction industries.
- Stable Structural Bearing Capacity: The steel plate features uniform texture and reliable tensile, compressive and bending resistance. It can stably bear static and dynamic loads, providing solid structural support for various engineering and mechanical equipment.
- Excellent Secondary Processing Performance: It supports diversified processing methods including cutting, bending, stamping, drilling and welding. It is easy to form and process, adapting to customized production of various mechanical parts and structural components.
- Superior Weldability & Assembly Performance: With stable material properties, it ensures firm and crack-free welding joints, convenient for on-site splicing, assembly and construction, and meets the requirements of large-scale structural installation.
- High Cost-Effectiveness & Durability: It balances performance and price perfectly. The raw material is economical and easy for anti-corrosion treatments such as painting and galvanization, effectively extending the service life of finished products.
- Strong Environmental Adaptability: It has good temperature resistance and structural stability
under conventional working conditions, suitable for long-term use in indoor, outdoor and general industrial environments.
- Steel Structure & Construction Engineering: Adopt premium grades of ASTM A36 hot rolled carbon steel plate Q235B for general structural construction and Q235JR, widely used for factory building frames, steel platforms, stair components, guardrails, embedded parts, steel brackets, municipal engineering facilities and building load-bearing structures.
- Mechanical Equipment Manufacturing: Applied in equipment base frames, mechanical housings, chassis supports, standard and non-standard mechanical parts, conveying equipment and general industrial machinery components.
- Heavy Industry & Engineering Machinery: Apply high-strength grades including S355JR low alloy high strength hot rolled steel plate for bridge and machinery manufacturing, Q355B, Q355JR and Q345B, suitable for manufacturing engineering equipment frames, crane accessories, forklift structural parts, load-bearing connecting plates and heavy mechanical support components.
