Hot Dipped Galvanized Steel Stair Treads Grating 30-60mm Series Distance with 500-1200mm Length Options
Hot-dipped galvanized steel stair treads are engineered for industrial and commercial applications requiring durable, slip-resistant flooring solutions. These treads combine non-slip surfaces with reinforced side panels for optimal safety and longevity.
Directly welded to supporting structures for permanent installation. This method offers maximum durability and cost-effectiveness but cannot be disassembled for reuse.
Features thicker side panels with pre-drilled holes for bolt-on installation. Ideal for applications requiring periodic disassembly, maintenance, or relocation.
For optimal cost-efficiency, we recommend using standard module widths (Series 1: 125, 155, 185, 215, 245, 275mm; Series 2: 125, 165, 205, 245, 275mm) with lengths in 100mm multiples (500, 600, 700, 800, 900, 1000, 1200mm).
