FAQ

Round Steel Tube — Frequently Asked

What is a circular hollow section (CHS)?

CHS is round steel tube used as a structural hollow section. We supply galvanized and black CHS / round steel pipe in a wide range of diameters and wall thicknesses.

Do you offer hot-dip or pre-galvanized round tube?

Both. Hot-dip galvanizing gives a thicker zinc layer for outdoor use, while pre-galvanized suits lighter applications. Black and painted finishes are also available.

Do you offer custom OD and OEM?

Yes. Outer diameter, wall thickness, length and surface are all customizable, and OEM manufacturing is welcome.
