Product Description
1. Commodity:
Square tube, other name: Square tubing, Square hollow section, SHS, Square hollow profile.
2. Definition
Square steel pipe is a kind of square pipe, which is a steel pipe with equal sides. It is rolled from a strip of steel. It is to unpack, flatten, crimp, and weld the strip to form a round tube, which is then rolled into a square tube and then cut into the required length.
Square steel can be divided into seams and seamless. Slotted square steel is welded together by steel plates to form square steel pipes. Seamless square steel is made from seamless steel tubes. Its compressive capacity is much greater than that of a square pipe.

5. Usage
Square steel pipes can be widely used in machinery manufacturing, construction, metallurgical industry, agricultural vehicles, agricultural greenhouses, automobile industry, railways, highway guardrails, container skeletons, furniture, decoration and steel structure.
6. Preservation method
1) Before the storage, the materials should be protected from rain or impurities. For materials that have been rained or soiled, use different methods to clean them. For example, high-strength steel can be used wire brushes to wipe. Steel with low hardness can be wiped with cloth, cotton, etc.
2) Always check the materials after storage. If there is rust, remove the rust layer.
3) After the surface of the general steel is removed from the net, it is not necessary to apply oil, but for high-quality steel, alloy steel sheet, thin-walled tube, alloy steel pipe, etc., and after the rust is removed, the inner and outer surfaces need to be coated with anti-rust oil before storage.
4) For steels with severe corrosion, it should not be stored for a long time after rust removal.
