Appearance Of Galvanized Sheet

(1) Surface condition: Due to different treatment methods in the coating process, the surface condition of galvanized sheets also varies, such as ordinary zinc flakes, fine zinc flakes, flat zinc flakes, zinc free flakes, and phosphating treated surfaces. German standards also specify surface levels.
(2) Galvanized sheets should have a good appearance and should not have defects that are harmful to the use of the product, such as lack of plating, holes, cracks, and scum, exceeding the plating thickness, scratches, chromic acid dirt, white rust, etc. Foreign standards do not have very clear regulations on specific appearance defects. When placing an order, specific defects should be listed in the contract.
