Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
We provide hollow Pipe of an ISO 9001:2008 certified company specializing in the manufacture of MS ERW Black, Hollow pipe sections are mainly used for industrial shade, Home Fabrication, Home furniture, Home interior, Idlers, Belt Conveyors, etc. The product has recently been enhanced with the addition of API Standards pipe manufacturing facilities.

A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology.
HSS members can be circular, square, or rectangular sections, although other shapes such as elliptical are also available. HSS is only composed of structural steel per code.
HSS is sometimes mistakenly referenced as hollow structural steel. Rectangular and square HSS are also commonly called tube steel or box section. Circular HSS are sometimes mistakenly called steel pipe, although true steel pipe is actually dimension and classed differently from HSS. (HSS dimensions are based on exterior dimensions of the profile; pipes are also manufactured to an exterior tolerance, albeit to a different standard.) The corners of HSS are heavily rounded, having a radius which is approximately twice the wall thickness. The wall thickness is uniform around the section.
In the UK, or other countries which follow British construction or engineering terminology, the term HSS is not used. Rather, the three basic shapes are referenced as CHS, SHS, and RHS, being circular, square, and rectangular hollow sections. Typically, these designations will also relate to metric sizes, thus the dimensions and tolerances differ slightly from HSS.

They offer strength and are used in construction and engineering applications for their load-bearing capacity and resistance to bending and torsion force.
Circular hollow sections are used as columns and braces in portal frames structures. An example is a 114.3 x 5 CHS, which has a diameter of 114.3 mm and the wall is 5 mm thick.
Similarly to RHS and SHS sections, hot rolled CHSs are made at the mill as one piece, whereas cold formed CHSs are made of a flat sheet rolled at a radius and welded.
It is theirfore easy to note the difference, as the cold rolled CHSs has a weld all along its length.
