YE-Series Modular Strut Channels
Single and back-to-back channels roll-formed from Q235B steel with serrated groove edges, axial stiffeners and published load tables — the backbone of every Qinyu support system.
Design Features
- Serrated groove edges — effective anti-shear, anti-slip and impact resistance for bolted connections
- Axial stiffener ribs — higher bending capacity and improved stability
- Marked graduations on the surface for fast, accurate cutting and assembly
- Material: Q235B steel to GB/T 700-2006; stainless SS304/SS316 and zinc-aluminum-magnesium on request
- Finish: pre-galvanized (275 g/m² passivated), hot-dip galvanized (HDG), epoxy-coated or stainless
