Product Parameters


Flat steel is a kind of metal material, usually refers to hot rolled steel plate or a kind of steel. It is rectangular or square in cross-section, with a long strip shape, rectangular in cross-section and slightly blunt edges. The width of flat steel is generally between 12-300mm, and the thickness is between 3-60mm. After hot rolling or cold drawing, flat steel has high hardness and strength and can withstand greater pressure and load.

Crafted from premium carbon/alloy steel, our flat steel balances high strength, weldability, and formability. Covering grades like Q235B, S235JR, A36, it fits construction frameworks, mechanical parts, automotive components, and more. Available in common widths/thicknesses with optional surface treatments (galvanized, pickled, etc.). Each batch comes with MTC, complying with ASTM, DIN, GB standards.





Production begins with the selection of low-phosphorus and low-sulfur steel billets, which are uniformly heated in a walking beam furnace to ensure optimal plasticity. The heated billets are then fed into multi-stand rolling mills for continuous rolling, where automatic gauge control (AGC) systems ensure precise dimensional accuracy. After rolling, the flat steel undergoes controlled cooling to refine its metallographic structure and enhance mechanical performance. The final steps include straightening, fixed-length cutting, surface finishing (as required), and strict visual and dimensional inspection. The entire process is digitally monitored and adheres to international quality standards, guaranteeing the stability and reliability of every piece of flat steel.





In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.





Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
