If the DFT is reduced to less than specified, the area shall be abraded as described above and an additional layerofcoating shall be applied until sufficient thickness is achieved.
Also need the final inspection process, color galvanized steel layerthickness can be used to determine the thickness of the coating device, the method is simple.
还得需求最后的查验过程,彩钢板镀锌层厚度查验可采用涂层测厚仪,办法对比简洁。

It is an inevitable tendency to reduce the thicknessof tin coating and alloy layer of tinplate.
