AST Pipes SCAFFOLDING TUBES AS PER BS : 1139
Ashtapad Overseas Ashtapad Overseas
We manufacture and export wide range of Scaffolding tubes that are characterized with high performance and provide the building industry with completely safe, economical solutions. They comply to the set industrial standards in terms of quality & safety. Generally, made of hot dipped, galvanized steel, which offers long-term corrosion resistance, it won't rot, absorb moisture, split, splinter, swell, warp or burn, thereby providing considerable life-cycle cost savings.



Scaffolding Tubes

Tubes Scaffolding are widely used for supporting man & materials, tools & tackles during construction alteration, demolition and maintenance works because of their suveral advantages over conventional type of timber/ bamboo scaffolding of an ancient time.

AST Pipes SQUARE AND RECTANGULAR HOLLOW SECTIONS FOR STRUCTURAL USE
Ashtapad Overseas Ashtapad Overseas
Hollow steel sections for structural use are the ones which are mostly used. Though hollow from the inside but still have great strength and provide good performance in many industries. They are mostly used in building construction industry. They may be used as water and sewage pipes. Round steel pipes are available in many diameters. They can be easily customized as required.
