Product Description

HOLLOW SECTION
A hollow structural section or HSS is a type of metal profile. It comes with a hollow tubular cross section. HSS can be circular, square, rectangular or elliptical sections. The sections are best suited for welding. They are corrosion-resistant and easily bendable which leads to the shaping and construction of structures without comprising on strength and durability.

SQUARE HOLLOW SECTIONS-SQUARE PIPE

They are manufactured up to a maximum size of 72x72 mm

RECTANGULAR HOLLOW SECTIONS-RECTANGULAR PIPE

They can be manufactured up to a maximum size of 96x48 mm

CIRCULAR HOLLOW SECTIONS- STEEL PIPE

They can be manufactured up to a maximum size of 80 NB

The hollow sections can be done according to the requirements of the buyer too. Each steel hollow section talks of high strength to weight ratio which results in savings in steel and costs.
