1. Surface quality observation points
Rib uniformity: Observe with the naked eye whether the horizontal rib spacing is consistent, without obvious missing or misalignment
Anti-corrosion treatment: The surface coating should be completely covered without missing plating or agglomeration
Flatness detection: The edge lift height should not exceed 5cm when laid flat on the ground
2. Performance verification method
Simple test:
Lightly scratch the surface with a hard object, and the high-quality coating is not easy to fall off
Bend the edge of the mesh, no cracking or coating peeling
Document verification:
Require suppliers to provide batch test reports
Focus on tensile strength and elongation data
