Galvanized Steel Rectangular Hollow Section

Galvanized steel rectangular hollow sections or rec tubes are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. In order to form the rectangular steel section the appropriate mother tube, a round steel tube, has to be formed first. 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.

Galvanized steel rectangular hollow sections circular HSS are sometimes mistakenly called steel pipe, although true steel pipe is actually dimensioned 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.

Hollow square pipes have numerous advantages, making them an ideal choice for construction projects. They offer strength, durability, and stability, are lightweight, require minimal maintenance, and offer sustainability advantages. The versatility of hollow square pipes allows people to use them across various construction projects. Based on these advantages, it's clear that hollow square pipes are an efficient and cost-effective solution that can enhance any construction project's structural integrity.
