Galvanized steel coil inspection
1. Size and shape measurement items: allowable deviation of thickness, width, length, unevenness, out of square degree and sickle bend.
2. Chemical composition test items: carbon content, sulfur content, manganese content, silicon content, phosphorus content, titanium content, aluminum content, niobium content, vanadium content, etc.
3. Physical performance test items: yield strength, tensile strength, elongation after breaking, R value, N value, tensile strain mark, baking hardening value, coating adhesion, coating weight, coating surface structure, surface quality, adhesion and corrosion resistance.
4. Environmental performance evaluation test items: lead content, content, cadmium content and hexavalent chromium content.
5, galvanized sheet brand identification
Galvanized steel coil can be widely used in different applications after further processing,including:
1.Galvanized steel Coil for Construction
They are often used as roofing,interior and exterior wall panels,the surface sheet of the balcony,ceiling,partitioning walls,windows and doors,gutter,barn,sound insulation wall,etc.
2.Galvanized steel Coil for Home using
GI coil is widely applied to home appliances,such as the base of washing machines, water heaters, refrigerators, microwave ovens,etc.
3.Galvanized steel Coil in Transporation Industry
