Carbon steel square pipe is a square section of steel pipe, mainly composed of carbon, manganese, silicon, phosphorus, sulfur and other elements. Carbon steel square pipe is a widely used pipe, according to the specific use and process requirements, its material is also different. In general, the material of carbon steel square pipe is divided into ordinary carbon steel, alloy steel and special steel three types. Carbon steel square pipe has a variety of excellent properties, including corrosion resistance, wear resistance, high strength, easy processing, etc.

Q345/S355JR/Gr.50 Carbon Steel Rectangular pipe is a kind of rectangular square tube made of carbon steel, which has high strength, good corrosion resistance and welding performance. It is widely used in construction, machinery, furniture, automotive and other industries, is an indispensable steel in the field of engineering.
The square pipe material is generally carbon steel square pipe and low alloy square pipe material. Most of the square tubes are made of steel tubes, which are formed into round tubes by unpacking, flattening, crimping and welding processes, round tubes are rolled into square tubes, and then cut into the required length, square tubes are divided into decorative square tubes, mechanical square tubes and construction square tubes, etc., square tubes are used in construction, machinery manufacturing, steel structure and other engineering use, its main components are carbon and iron, with good plasticity and mechanical properties.
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.
