In many industries, construction, medicine, and everyday life galvanized sheet is used, obtained from rolled steel. Fences, roofing, gutters, gutters are made of it. Not a single production producing household appliances is complete without this material. This also applies to automotive, aviation and many other mechanical engineering industries.
For the production of galvanized sheet metal is used of the highest quality that meets the requirements of GOST. Therefore, it is lightweight, durable, resistant to moisture and other negative environmental influences. Another major advantage of this material is its durability, which makes it very popular. This type of rolled metal can have a smooth, corrugated, corrugated, painted surface, which is determined by the processing method.
Production of galvanized sheet from hot-rolled steel begins with descaling and rolled metal strip to the required thickness. Then, degreasing, pickling and rinsing of the steel surface are carried out.
After annealing, the sheet is galvanized in a special bath, during which a very thin layer of zinc is applied from 0.01 to 0.06 mm. This gives it a smooth surface, shine and increases corrosion resistance. After cooling, the sheet from the rolls is cut into strips according to a specific size specified by the customer. In addition, the material is often sold in rolls, which are 1250 mm wide.
Steel sheet made of cold-rolled metal has even higher anti-corrosion properties and strength. To make the appearance of the sheet more attractive, it is painted or aluminum and lead are added during the galvanizing process. A high-quality sheet should not contain torn edges, cracks, dark marks and specks. There may be minor defects, but they are precisely established by GOST. The material obtained after galvanizing can be easily processed: cut, drill, bend. It does not require special maintenance and repair, therefore, it allows you to significantly save money.
Often, galvanized sheet is used to obtain products using different processing methods: stamping, bending, rolling, drawing. Excellent performance properties, affordable price, ease of installation make this material attractive to buyers.
