Square hollow section

Square hollow section comes in different sizes, specifications and wall thicknesses.

· Rectangular/ Square hollow section process

· The cause of rectangular tube welding

· How to improve rectangular welding technology

· Rectangular Hollow Section uses

· Large diameter square tube defects

· Hot dip galvanized square tube

· HSS (Hollow Structural Steel)

Its uniformity makes it predictable to use and visually appealing.

It has a high weight-to-strength ratio. It’s easy to bend, and because square steel tubing is inexpensive, it’s cost-effective- even for large projects.

Square Hollow Section, SHS, Square Box, Painted, Galvenised, ERW, Black, Mild Steel

· Steel Grade: Q235, Q345, S235JR, S275JR, SS4007

· Surface Finish: hot dipped galvanized, Pre-galvanized

· SHS (Square Hollow Section) Size range Table 2. 

Steel tube is easily recyclable. Many projects take advantage of square steel tubing, including all types of buildings, highway guardrails and signage, support columns, trusses, bridges, heavy equipment, storage systems, and exercise equipment.

A wide range of dimensions, when combined with the appropriate steel grade, ensure that the functionality and cost-efficiency of your structure can be optimised.
