We supply high-quality carbon steel bars in various specifications including round, square, hexagonal and flat shapes (diameter 5mm-300mm). Manufactured from premium low, medium and high carbon steel grades (Q235, 1045, 4140, etc.), our products feature excellent machinability and weldability, making them ideal for construction, machinery manufacturing, automotive industry and other applications.

Our bars are produced through precision hot-rolling and cold-drawing processes, equipped with automated temperature control systems and online dimensional inspection (±0.1mm tolerance), with an annual production capacity exceeding 100,000 tons. We implement rigorous quality testing procedures including chemical composition analysis (C, Mn, Si content), mechanical property testing (tensile strength 400-850MPa), surface quality inspection and dimensional accuracy verification. All products comply with international standards such as ASTM A29 and EN 10025, and come with complete quality certification documents.

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.
