CHS Range
Overview
Available in DuraGal, Painted, Hot-Dip Galvanized and Structural, CHS (circular hollow sections) are high-strength cold-formed hollow steel circular sections that are primer painted for protection during storage and handling. CHS is often used when strength and functionality is essential in structural and mechanical applications. DuraPrimed primer paint for tubular steel products has been developed specifically to save users time and money without compromising quality.
Steelforce’s CHS products are available in a range of heights (diameters??) and thicknesses from 17.2mm OD to 219mm OD. Our CHS products are manufactured to the Australian Standard for structural steel hollow sections AS/NZS 1163:2016 and are available in steel grades of: C350LO and C250. See Product Guide
CHS can be used for various applications, most commonly the manufacturing of frames, residential projects for gates and posts, as well as other commercial and agricultural purposes.
There are a variety of surface finishes across our range of CHS product, however, not all finishes and grades are available in all sizes.
