PRODUCT DETAILS
📌 Quality inspection standards for galvanized steel coils
📌 Surface quality inspection
The surface quality of galvanized steel coils has an important impact on its appearance and service life. Common surface defect inspection standards include:
Rust spots: There are no obvious rust spots on the surface, and the galvanized layer should evenly cover the surface of the steel.
Scratches and bumps: There should be no obvious scratches, marks or other mechanical damage on the surface.
Oil stains: Ensure that there is no oil stains and other contaminants on the surface of the steel coil to avoid affecting the adhesion of the galvanized layer.
📌 Tensile performance test
Through tensile testing, the mechanical properties of galvanized steel coils, such as yield strength, tensile strength, elongation, etc., are tested to ensure that they meet the standard requirements. Common standards include:
GB/T 708: Standard for mechanical properties of steel materials.
ASTM A1008: American standard, mainly used to evaluate the mechanical properties of cold-rolled steel.
📌 Yield strength and tensile strength test
Yield strength and tensile strength are important indicators of whether galvanized steel coils can withstand tensile stress. They are usually tested by special tensile machines to ensure the safety of galvanized steel coils under different use conditions.
📌 Corrosion performance test
Use accelerated corrosion tests (such as salt spray tests) to test the corrosion resistance of galvanized steel coils and check their antioxidant capacity in harsh environments such as humidity and salt spray. Qualified galvanized steel coils should be able to resist salt spray corrosion for a certain period of time.
