Square steel tubes (or we can name it as square hollow section) come in different sizes, specifications and wall thicknesses. Its uniformity makes it predictable to use and visually appealing. It has a high weight-to-strength ratio. Compared to round steel pipe, square steel tube is more efficient, stronger and durable. It's easy to bend, and because square steel tube is inexpensive, it's cost-effective -- even for large projects. Many fields take advantage of square steel tube, including all types of buildings, constructions, highway guardrails, support columns, trucks, cranes, bridges, heavy equipment, machinery, storage systems, and exercise equipment, shipbuilding, chemical industry etc.
There are two types of square steel tube: welded and seamless.
Square steel tube/square hollow section conforms to GB/T3094-2000, GB/T6728-2002, JIS G3466, EN10219/10210, and ASTM A500 standards. Nominal tube size in mm, the outside diameter in mm, the series of pipes, the wall thickness in mm.
