SCAFFOLDING
TUBES AS PER BS : 1139
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.

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.

SQUARE
AND RECTANGULAR HOLLOW SECTIONS FOR STRUCTURAL USE
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.
