HOLLOW SECTION square&rectangular steel pipe diveded into seamless and weld , Producing method: Hot rolled or cold formed, ERW Steel Pipe, Galvanized Steel Pipe, seamless square tube is made of seamless tube extrusion process can also be processed through the strip roll is made. Usage industry: Structure pipe in constructions, making machinery and shipping building , bridge building And so on
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.
