Circular Hollow Sections (CHS) are hollow structural profiles widely used as load-bearing elements in modern architectural and structural engineering projects. Eren Boru supplies CE marked circular hollow sections to the construction sector, produced to EN 10219 (cold-formed) and EN 10210 (hot-formed) standards.
Manufactured in structural steel grades from S235 to S460 MH/NH, also covering ASTM A500 Gr A/B/C and EN 10305-3 standards, our profiles are available in outside diameters from 21.3 mm to 339.7 mm and wall thicknesses from 2.0 mm to 12.7 mm.
Supplied with plain end square cut or beveled finish, in black self-colored/uncoated surface or with protective oil/varnish coating, these profiles undergo comprehensive quality control including tensile, flattening, flaring, expanding, and impact tests.
Applications
- Steel structure load-bearing systems and columns
