The anti-slip treatment process of anti-slip steel scaffold planks is implemented on the steel plank surface before anti-corrosion treatment,following a step-by-step operation flow with no enterprise-related information involved,and the core processes are classified into mechanical processing and coating processing with unified pre and post-treatment steps.
Pre-treatment:First,remove oil stains,rust,dust and oxide skin on the steel plank surface through pickling,phosphating or shot blasting to ensure the surface is clean and rough,which improves the bonding force of the anti-slip structure or coating with the steel base.Then,flatten and straighten the steel plank to avoid surface warping affecting the subsequent anti-slip processing effect.
Core Anti-slip Layer Formation
Mechanical Embossing Process:Adopt a hydraulic embossing machine to press regular anti-slip patterns(diamond,round dot,stripe)on the steel plank surface at a specific pressure;the embossed convex parts form anti-slip nodes,with the pattern depth controlled at 1.5–3mm to balance anti-slip performance and walking comfort.
Serrated Cutting Process:Use a precision cutting machine to cut continuous triangular serrations on the steel plank surface along the length direction,with the serration height of 2–4mm and spacing of 5–8mm;this process is suitable for heavy-duty scaffold planks with high anti-slip requirements.
Non-slip Coating Spraying Process:Spray a high-wear resistant anti-slip coating(epoxy resin,polyurethane with anti-slip sand)on the pre-treated steel surface,with the coating thickness of 0.5–1mm;the anti-slip sand with a particle size of 0.3–0.8mm is mixed in the coating to form a rough anti-slip surface,suitable for indoor or low-abrasion construction scenarios.
Post-treatment:After the anti-slip structure formation,conduct edge trimming to remove burrs and sharp edges on the plank surface to avoid construction scratches.Then perform hot-dip galvanizing or electro-galvanizing anti-corrosion treatment on the whole plank(mechanical processing planks)or cure the anti-slip coating at a constant temperature(coating processing planks)to enhance the durability of the anti-slip layer and the whole plank.
All processes shall comply with construction scaffold component standards,and the anti-slip surface after treatment shall have a friction coefficient≥0.6 to meet the on-site anti-slip safety requirements.
