Galvanized steel, or as professional sellers of metal products call it, galvanized , today is more in demand than ever in various sectors of the national economy and, above all, in construction. Let's briefly understand what it is and why this steel is called galvanized.
Galvanized steel production
The technology of rolling steel sheet was applied in production in the second half of the IXX century. The world was preparing for the First World War. The armies needed ships, tanks, armored vehicles. By the XX century, the mass production of thin sheet steel suitable for the manufacture of basins, buckets, troughs had been established. To protect against corrosion, steel sheets were dipped in a bath of molten zinc. So gradually galvanized steel in the form of household utensils entered every house and even covered it. The roofs of houses used to be covered with black wrought iron or copper sheets. Galvanized roofing iron has pushed the competition out. Modernization of production allowed rolling steel coils with a thickness of 0.3 mm . The zinc coating is applied by electroplating, in a thin layer.
Galvanized Steel Application
The method of large sheet corrugation has finally secured the leading position in the roofing business for galvanized steel . Corrugated sheets have longitudinal stiffness and can be overlapped. Sheets with a rectangular bend profile are used as fence sections for fencing. Traditional use in the construction of ebb tides on window sills and parapets. Rainwater pipes and sheet gutters are still popular. The beginning of the new century was marked by the massive replacement of roofing with the so-called metal-tile roof. For production, sheet galvanized steel with a thickness of 0.3 mm to 2.5 mm is used, on which a polymer coating of various colors is applied. A special stamp creates a relief pattern on the surface that resembles a tile.
