Square steel tubing

Square tubes are incomparable in building decoration, machinery manufacturing, steel structure engineering, and glass curtain walls. Moreover, it is common in daily life. For example, the security window and the guardrail are all used in the square tube. The main reason is that the application will have unexpected effects, especially the selection of the square tube size. This is an important link. Because this means safety hazards, such as the installation of protective railings in the construction square steel tubing industry, there have been reports in the past, because the protective railings are broken, the number of casualties can be said to be countless, so the square tube square tube size can not be sloppy.

What is the square tube?

As the name implies, the square tube is a square tube type. A variety of materials can form a square tube. It is used in the medium, and what is used. Most square tubes are made of steel pipes. Flat, curled, welded to form a round tube, which is then rolled into a square tube and then cut to the required length. Generally, 50 square tubes per package are mostly in the size of 10*10*0.8-1.5~~500*500*10-25. The square tube is divided into structural square tube, decorative square tube and building square tube according to the purpose. , mechanical square tube, etc.

The square tube is a hollow square section light thin-walled steel pipe, also known as steel refrigeration curved profile. It is a section steel of square cross-section shape made by Q235 hot-rolled or cold-rolled strip or coiled steel as the base material after cold bending forming and then high-frequency welding. In addition to the thickening of the wall thickness of the hot-rolled thick-walled square pipe, the corner size and the straightness of the edge are both at or above the level of the cold-formed square tube of the resistance welding.
