Structural Steel Tubes
Major Application of Structural Tubes :
Scaffolding :
Our wide range of steel scaffolding pipes are of superior quality which meet the international standard and guidelines. The pipes are made from high quality Hot Rolled Coils, making it highly erosion resistance. They are available in various specifications. The scaffolding pipes are used in the construction or repair of buildings for supporting the structure.
Thick steel scaffolding pipes are used to support heavy platforms, which hold heavy loads & withstand movements. Generally made of hot dipped galvanized steel, so as to offer long term corrosion resistance, even Black pipes are used depending upon the usage conditions.
Other Application of Structural Steel Tubes :
- Casing
- Columns
- Fence
- Handrails
- Load Bearing Structure
- Piling
- Posts
- Poles
- Railings
- Scaffolding
- Sign poles
- Skywalks
- Towers
