详情描述
Uniform spacing, neat molding, and attractive appearance. Equipped with two grooves in the middle of the plank, which enhances the compressive strength of the steel plank. Even when subjected to pressure and bending, it can return to its original shape after the pressure is released, making the steel plank less prone to deformation. It also features anti-slip, anti-sand accumulation, fire resistance, and high reusability rate.
Common specifications for hot-dipped galvanized steel plank are 2.0m x 210mm x 45mm, 3.0m x 210mm x 45mm, and 3.0m x 240mm x 45mm. The standard thickness of the steel plank production material is 1.2mm.
Steel plank material requirements: Made from cold-rolled galvanized steel strips with thickness of 1.2-2.0mm, the material must comply with the National Standard "Technical Conditions for Ordinary Carbon Structural Steel" (gb/700-70), and the steel quality should be above Q235.
Quality requirements for steel ladder platforms:
Hot-dip galvanized steel plank dimensions: 2000mm-3000mm-4000mm in length, 240mm in width, and 45mm in height.
2. Hot-dip galvanized steel plank dimensions: length tolerance not exceeding 3.0mm, width not exceeding 2.0mm for the steel plank factory, and hole flange height tolerance not exceeding 0.5mm. Anti-slip hole diameter: 12mm x 18mm, hole spacing: 30mm x 40mm, flange height: 1.5mm.
3. The end plate and discontinuous rib are reinforced with spot welding, ensuring the weld seam remains flat.
4. Hot-dip galvanized steel plank surfaces should be flat, with surface deflection not exceeding 3.0mm.
5. Hot-dip galvanized steel plank edges must be deburred and flattened.
6. The folding angle of the hot-dip galvanized steel ladder should be maintained at 90°, with no deviation exceeding 2°.
