Description

Square steel tube hollow section for heavy steel structure|colled formed|hot finished|large size
Heavy steel structure square steel pipe
Heavy steel square steel pipes refer to square steel pipes specifically used in heavy steel structures. Usually four steel pipes with equal sides. It is made of rolled and welded strip steel through process treatment. Some are also seamless steel pipes.

Classification of Steel Structures in China
Classification of Steel Structures in China
Steel structures are divided into heavy steel structures and light steel structures. Heavy steel structures are further divided into high-rise heavy steel structures, spatial steel structures, bridge steel structures, and equipment steel structures.
The editor learned that the heavy steel structure we refer to in daily life is a high-strength steel structure with good fire resistance and corrosion resistance. Due to its high strength, good rigidity, high temperature resistance, and wear resistance, it is widely used in fields such as aerospace, automotive manufacturing, and wind power generation. Heavy steel structures are mainly composed of plates, connectors, and fasteners. The steel plates are usually made of low-carbon steel or alloy steel, and the connecting materials are steel pipes or welded steel pipes; Fasteners generally use bolts, nuts, or rivets; Fasteners also include connecting rib plates, gasket plates, lock nuts, sealing washers, and so on. Due to its reasonable design, convenient installation, and low maintenance costs, the heavy steel structure has been widely welcomed in many engineering applications.
The heavy steel square hollow section steel is suitable for the main components of buildings, bridges, and other structures, as well as for situations that bear large dynamic loads. Therefore, it must meet the following properties of heavy steel structures

How much is a 4x4 square tube 6M?
A 4x4 square tube costs over 30 yuan per square meter.

The inner walls of square tubes vary in thickness and price. four × four × The price of 0.1 square tube is over 30 yuan. Standard size of square tubes: 6 meters per piece. The price of square tubes is mainly calculated by weight in the market. The price of one tube depends on its thickness. Generally, for galvanized square tubes with a thickness of 2mm, it costs about 40 yuan per piece. Of course, there may be regional price differences, and the specific price depends on the market situation of your local steel market.
