Tianjin galvanized square rectangular tube manufacturers, the other uses and characteristics of the tube are introduced.

Tianjin Guangxin Iron and Steel Industry and Trade Co., Ltd., as a manufacturer of galvanized rectangular tubes in Tianjin, will introduce the use and characteristics of rectangular tubes today.

We need to check the surface of the rectangular tube. If there is scarring on the surface, it means that the raw materials used in the square tube are not good and the impurity content is relatively high, which leads to scarring. This phenomenon can be found only by careful observation.

Also check the surface lines of galvanized square pipe, good product lines are more evenly distributed, there will be no cracks, if found cracks, indicating that the quality of the raw materials used is too poor, in the production process can not bear the heat, will eventually lead to cracks.

The uses of square pipes include construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation supports, steel structure engineering, power engineering, power plants, agriculture and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other high-load welded structural parts.

Tianjin galvanized square rectangular tube manufacturers, sales of square tube is a hollow square section of light thin-walled steel pipe, also known as steel cold-formed profiles. It is Q235 hot-rolled or cold-rolled strip steel or coil as the base material by cold bending forming, and then by high-frequency welding made of square cross-sectional shape of steel.
