Description
The quality of black plastic coated wire mesh is the manufacturer's primary concern. We must consider not only the substrate performance and coating quality, but also structural precision and durability. We conduct pre-shipment inspections, and users should also inspect the products immediately upon receipt. The main inspection items include the following:
Performance testing: Wire diameter measurement, actual diameter error ≤ ±0.05mm from nominal value, zinc layer thickness meets requirements, hot-dip galvanized layer ≥ 245g/㎡, electro-galvanized layer ≥ 80g/㎡, cut a single wire and stretch it to break using a tensile testing machine, tensile strength ≥ 350MPa, elongation at break ≥ 10%, zinc layer without peeling, flaking, or cracking;
Coating quality inspection: The coating of Black Plastic Coated Wire Mesh can often serve an aesthetic purpose, but in addition to aesthetics, performance must also be up to standard. The coating thickness is 0.3~0.5mm, and 0.6~0.8mm for coatings in highly corrosive environments. The adhesion test is qualified, the coating is uniform, and it meets the requirements of the neutral salt spray test. After the test, the coating shows no blistering, rusting, or peeling.
Structural accuracy inspection: Mesh size measurement and mesh specification inspection must meet the user's requirements. Weld points are inspected by clamping the steel wires on both sides of the weld point with pliers and slightly twisting or pulling them. The weld point should not fall off or crack.
Packaging Inspection: Visually inspect the packaging appearance. It is wrapped with moisture-proof film and woven bag, and the sheet mesh is fixed with cardboard to ensure that there is no damage, moisture, or deformation. Check the outer packaging label to see if it indicates the product specifications, order number, destination, gross weight, net weight, and includes a material test report and installation instructions.
