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.
