GALVANIZED SHEET SHEET

galvanized Coil Sheet

After hot rolling and pickling surface cleaning processes, full hard material with suitable surface quality and thickness (0.25-2.00 mm) for the galvanizing line is produced by the cold rolling process in the reversible cold rolling (CRM).

Galvanization with Hot Dip Method (HDGL), continuous annealing in the galvanizing line and then zinc coating with zinc pot dipping method is performed. Chemical passivation and protective oil can be applied to the surface of the zinc-coated material as a preventative against corrosion. It is possible to produce in the range of 0.25-3.00 mm thickness and 800-1530 mm width in the hot-dip galvanizing line.

GENERAL INFORMATION ABOUT GALVANIZED PRODUCTS

Galvanized is 100-275 gr/m2 zinc coated sheet in accordance with EN 10143:2006 standard, galvanized in continuous lines with the hot-dip method. Galvanized coating increases the corrosion resistance of the sheet. It is resistant to impacts and wear caused by the hardness of galvanized sheet.

In summary, Galvanized Sheet; It is defined as a carbon steel sheet coated with zinc on both surfaces. With the continuous galvanizing method, the coating process of the sheet is made and it is made both smoother and corrosion resistant. Galvanized sheets are widely used in various business lines of industry.

GALVANIZED SHEET USAGE AREAS

Galvanized Coil Sheet and Galvanized Plate Sheet are used in automotive, white goods, electrical – electronics, small household appliances, heating and cooling, ventilation, construction (PVC reinforcement sheet, open structure profile) etc.
