Steel coil factory inspection standard
2023-08-08
Color coated steel coil inspection standards can be from the specification size, coating, surface inspection, labeling requirements in several aspects.
01 Specification size
The tolerance of width is +-2mm, the cut is straight, the cut surface is neat, and the tolerance of thickness is +-0.03mm.
02 Coating
The coating type meets the contract requirements, the coating color is uniform, no obvious color difference, and the coating thickness meets the contract requirements.
03 Surface Inspection
The surface of the coil is smooth, no obvious concavity, convexity, warping, deformation, clean surface, no oil stains, no bubbles, shrinkage holes, leakage of coating and other defects harmful to the use of the surface, the defective part of the steel coil is not more than 5% of the total length of each coil, and there are no obvious scratches, knocks and scars.
04 Labeling requirements
Packaging pieces of paper or other material products must have the product name, specifications, manufacturers, etc., packaging mark conspicuous, firm, clear handwriting, and note the name of the supplier or supplier's trademarks, standard numbers, grades, specifications, weight, packaging mark indicates that can be traced from the steel to the smelting of the identification number, the quality certificate must indicate the name of the supplier, the contract number, the name of the product, the standard number, specifications, grades, and can be traced Identification number from steel to smelting, weight, number of pieces, date of production and shipment date, the logo must indicate the weight of the substrate plating, topcoat type, color and so on.
