steel pipe knowledge

Square steel tube products play an essential role in modern construction and structural engineering. As a leading Chinese manufacturer, Yuantai Derun focuses on innovation, quality control, and reliable service for global customers.

When you invest in steel structures, you need lasting protection. Rust is the enemy, and it never sleeps. Selecting the right coating for your square steel tube determines your project's lifespan. We have served the steel pipe market for decades, and we understand your quality demands.

At present, water is often used as the quenching agent in the heat treatment of square rectangular pipes.

Artificial salt spray test includes neutral salt spray test, acetic acid salt spray test, copper salt accelerated acetic acid salt spray test, and alternating salt spray test.

It is difficult to define the weight of a steel pipe. In general, the reduction of wall thickness has a greater impact on the bearing capacity in compression than in tension.

With the development of steel structure technology and the application of steel frame system, the envelope no longer needs to bear the load, thus promoting the development of lightweight envelope such as glass curtain wall. Under the dual-carbon goal, the requirements for green buildings will continue to increase. As an important part of building energy conservation, the BIPV market has a broad prospect.

Square rectangular steel pipe is the main data in construction. The most important thing for us is quality. Most construction enterprises need to purchase more square tubes at one time, However, now there are many manufacturers that supply this kind of profile, and the product quality and quotation of each manufacturer are different, so how to measure its quality? How to buy high-quality products?

How much is the manufacturer's price of hot-dip galvanized square tube? How much is the wholesale price of hot-dip galvanized square tube? These two issues are very important and we must understand them.

Sharp angle square tubes are very common in practical applications, and there are many different types of sharp angle square tubes to choose from. Therefore, when selecting the sharp angle square tube, it is necessary to select the appropriate sharp angle square tube according to the actual application.

The production process of straight seam steel pipe is relatively simple. The main production processes are high-frequency welded straight seam steel pipe and submerged arc welded straight seam steel pipe. Straight seam steel pipe has high production efficiency, low cost and rapid development.
The strength of spiral steel pipe is usually higher than that of straight seam steel pipe. The main production process is submerged arc welding.
