Why Choose Us

Product Advantages
Galvanized steel pipes have good structural strength and compression and impact resistance. They can adapt to various complex environments and have a wide range of applications. They can be used in fire protection, gas, water supply and drainage and other fields. They are economical, practical and reliable pipes.

Advanced production technology
The production process of galvanized welded pipes usually includes the steps of unwinding the steel strip, forming welding, and galvanizing. First, the steel strip is unrolled and rolled into a tube through a forming device, and then welded to form a welded pipe. Next, after pretreatment such as pickling and water washing, galvanizing is carried out. Hot-dip galvanizing is to immerse the welded pipe in zinc liquid, while electrogalvanizing is to deposit the zinc layer through electrolysis.

High-quality product performance
Strong corrosion resistance: After galvanizing, a zinc layer is formed on the surface of the galvanized welded pipe, which can effectively prevent the steel pipe from being corroded. Long service life: Hot-dip galvanized welded pipe has a relatively long service life due to the uniform galvanized layer and strong adhesion. Easy to adjust and size: Galvanized welded pipe can produce steel pipes of various calibers by changing the forming angle, and the length can be set at will.
