How galvanized sheet metal is classified
A layer of zinc coating is applied to the surface of sheet or coil products made of carbon steel grades. Apply methods of hot, cold, galvanic or gas-thermal deposition. The method used in the manufacture is indicated in the technical passport for each batch of products. In this case, the layer can be applied both on one and on both sides of the sheet. An important parameter is the thickness of the applied zinc layer. According to GOST, there are 3 main categories:
- Highest class – galvanized on both sides with a thickness of 40 to 60 microns.
- First class - sheets are coated on both sides with a thickness of 18 to 40 microns.
- Second class - the minimum allowable coating thickness is 10 microns.
Product quality is determined visually. The surface should be flat, smooth, without chips and gaps. When bending or cutting the sheet, the zinc layer should not peel off. The manufacturer, before sending products to the consumer, covers the surface of the sheets with an oil composition, which simplifies the process of their transportation and storage.
