Fang? V-shaped steel pipe is one of all square pipes and steel pipe profiles, which generally refers to steel pipes with square or rectangular cross section. From the material point of view, square steel pipes mainly include stainless steel square steel pipes, alloy square steel pipes, carbon square steel pipes, galvanized square steel pipes, etc. From the perspective of production technology, there are mainly two categories: seamless square steel tube and welded square steel tube. Square steel tube is made of strip steel through a special process, that is, the strip steel is first processed into a round steel tube, and then the round steel tube is rolled into a square tube.
The performance of square steel tube is mainly evaluated from the aspects of plasticity, hardness, fatigue resistance, impact toughness and strength, which are also the main technical indexes that restrict the production of square steel tube. In production and life, we will choose different kinds of square steel pipes according to our needs, which is the technical index of square steel pipes in these aspects. Generally speaking, these technical indexes of square steel tubes are closely related to their materials. For example, the tensile, compressive, bending and shearing properties of low-alloy square steel tubes are better than those of ordinary square steel tubes.
Square steel tubes, like other types of pipes, have many specifications and models, and different specifications and models of square steel tubes have different uses. The following are some specifications of square steel pipes:

The application field of square steel tube is as wide as other steel tubes. Widely used in industrial production, construction industry, decoration industry and so on. For example, in industrial production, square steel pipes are used for fluid transportation, various engineering structures and mechanical parts, and the most common metal guardrail also uses square steel pipes. In some fields, the function of square steel tube is obviously better than that of round steel tube, for example, square steel tube is often used instead of round steel tube in the columns of buildings. The price of square steel tube will also be different due to its material, specification, model and other factors. The material of high-grade square steel tube must have excellent performance. When I buy, I should look for the product instructions of square steel tube, so that I can really buy square steel tube suitable for my own needs.
