Square Steel Pipes are divided into hot-dip galvanized and electro-galvanized, and welded steel pipes with electro-galvanized or hot-dip coating on the surface. Galvanizing can increase the corrosion resistance of steel pipes and extend the service life of steel pipes.


It is produced by steel strip and the main elements such as nickel, chromium and copper are of high purity and stability.

Square Steel Pipe Features: 

  • Good extension performance

  • Strong welding

  • High precision

  • flaring, shrinking, bending, taping within the standard range of processing

Square Steel Pipe

Rust removal method:

1. First clean the surface of the steel with a solvent to remove organic matter on the surface,

2. Then use tools to remove rust (wire brush) to remove loose or inclined scale, rust, welding slag, etc.

3. Use pickling method.

Square Steel Pipe Application:

  • construction, coal mines 

  • automobile industry, highways, bridges

  • containers, sports facilities

  • agricultural machinery
