OEM/ODM project supply · Q235B / Q355B · 41×21 – 41×62 mm · Hot-dip galvanized ≥ 65 μm
Complete roll-formed steel framing for solar mounting systems — columns, beams (purlins) and rails in four standard C-channel sections, pre-punched with adjustment holes and delivered in 6 m standard lengths cut to your project dimensions. Everything bolts together on site: no welding, faster installation, and a 25-year design life backed by hot-dip galvanizing.
CNC-punched adjustment holes and fixed-length cutting at the factory — components arrive ready to bolt together.
Fully bolt-assembled design with matching clamps, Grade 8.8 bolts, nuts, washers and connectors — faster, safer installation.
41×21, 41×41, 41×52 and 41×62 mm with wall thickness 2.0 – 3.0 mm; custom sections produced on request.
Hot-dip galvanized ≥ 65 μm as standard, ≥ 85 μm for coastal environments; Mg-Al-Zn S350GD+ZM275 coating optional.
Designed for max wind speed 60 m/s and max snow load 1.4 kN/m², with a 25-year design service life.
6 m standard bars cut to custom lengths per project — mixed sizes can ship in one consolidated container.
All parameters can be customized to your project drawings or bill of quantities.
