Gi square pipe is a kind of hot dip galvanized square steel pipe.Yuantai Derun is the largest manufacturer of hot-dip galvanized square pipes in China, providing galvanized square pipes for over 6000 major projects worldwide.

2.What Material Is Gi Square Pipe?

This type of pipe is mainly made by coating a layer of zinc plating on the surface of the steel structure. That is to say, the inside of the galvanized square tube is actually a steel structure. Due to the galvanized processing on the surface of this type of pipeline, it can effectively prevent signs of corrosion or rust on the steel, thereby extending the service life of the steel structure.

3.What Are The Classifications Of Galvanized Square Tubes?

According to the amount of zinc, it can be divided into galvanized square tube and Hot dip galvanized square tube.
According to the welding process, it can be divided into seamless galvanized steel square tube and galvanized welded square pipes.

5.Physical Properties Of Galvanized Square Tubes

Due to different production processes and galvanizing methods, different galvanized square pipes have many different physical and chemical properties. Generally speaking, they have significant differences in strength, toughness, and mechanical properties. 
If you want to know more ,please contact us now!

6.Application Of Galvanized Square Tubes

Galvanized square tube is a type of square tube treated with a zinc layer, which can form a dense layer of quaternary crystals, effectively preventing corrosion factors from corroding. At the same time, zinc can also serve as sacrificial protection in the cut edges, scratches, and coating scratches, forming an insoluble oxide layer, thereby playing a barrier protection function and greatly improving the corrosion resistance of the square tube. And this corrosion resistance comes from the strong protective function of the barrier layer of zinc.

In fact, not only galvanized square pipes, but also many items, such as car parts, furniture hardware, and so on, will be coated with zinc. This is because zinc not only effectively prevents corrosion, but also has a beautifying effect. Moreover, the galvanizing process is becoming increasingly advanced and can be carried out through various methods such as electroplating and spraying, greatly improving production efficiency and quality.
