Product Description
Our 【Hexagonal hollow steel pipe】 sticks strictly to ASTM A500 (for structural steel pipes) and EN 10219 (for cold-formed profiles)-the standards European and American buyers actually care about.
What's great about these 【shaped steel tubing】 is their unique hexagonal design. Compared to round steel pipes of the same weight, they're way stronger-perfect for structural jobs like scaffolding, machinery frames, or even outdoor fencing where sturdiness matters.
The hexagonal shape also makes installation easier-you don't have to worry about them rolling around while you're working. We've got sizes from 18mm (across the sides) to 60mm, wall thicknesses from 1mm to 6mm, and lengths up to 6 meters-covers most of the projects your clients will need.
Plus, they work perfectly with our other hexagonal pipe fittings, like elbows and tees. That means you can easily offer your customers a complete set of parts, no need to source fittings from somewhere else.
