"Square tube" is a generic term for square pipes. Plastic pipes and steel pipes are the most commonly used in daily life. Nowadays, many household water supplies have already used plastic pipes made of PC or PV materials. The development of plastic pipes has greatly impacted the market for many traditional steel pipes. However, there are differences in length and length, and everything in the world has two sides, although many materials can form square tubes, However, its material determines what it is used for and where it can be used, such as steel square tubes, because their bending and torsion resistance properties are widely used in the manufacture of mechanical parts and engineering structures. Most of the square tubes we use in daily life refer to steel square tubes. There are many types of square tubes, including those classified by material, production process, and shape. In short, there are thousands of square tubes in total.

"Square tubes, as the name implies, are tubes that are released. According to the production method, they can be divided into integrated molding and post processing. Integrated molding refers to the direct processing of molten steel into square tubes by steel mills, which has the best effect. However, few steel mills do this. The most common thing we see is post processed square tubes. For example, our New Era Special Steel uses advanced cold rolling forming technology.", Unlike cold rolling forming, there are also hot rolling extrusion and welded square tubes. Due to different production processes, these types of square tubes are applicable in different fields. It is better for everyone to understand them in detail before making plans.

As we all know, there are different types of steel, which results in a variety of materials for square tubes. We can generally be divided into plain carbon steel square tubes and low alloy square tubes, which are commonly referred to as Q195, Q215, Q235, SS400, 20 # steel, 45 # steel, and so on; Low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.

In this era of individuality, square tubes are also unconventional operations and have been made into various shapes. Such square tubes are called special-shaped tubes. According to the simple cross-sectional shapes, we can divide them into square tubes and rectangular tubes. For some complex cross sections, we can divide them into flower shaped square tubes, open shaped square tubes, corrugated square tubes, and so on. In the market, we often classify square tubes according to their treatment methods, such as the commonly used galvanized square tubes and oiled square tubes.

Due to the various factors mentioned above, the use of square tubes is diverse, such as the square tubes for decoration closest to us, as well as the square tubes for highly specialized machine tools and equipment, the square tubes for mechanical industry, chemical industry, steel structure, shipbuilding, automobile, steel beams and columns, and special purposes. Finally, there are a special type of square tubes with thick wall thickness and thin wall, There are also ultra thick square tubes in the middle.
