Hot-Dip Galvanized Coils

The Hot-Dip Galvanized Coils are used in the constructions industry, as material for production of the corrugated panels, steel sheets, metallic strip for fences, profiles for the gypsum-cardboard panels, ventilation systems, steel accessories. Recommended to be used both outside and inside of the buildings, the hot-dip galvanized coil is a product with a high resistance to the corrosion from the various mediums.

The resistance against corrosion is due to the covering with a protective layer of zinc from 100 to 275 gr/sqm, on the coils’ both sides.
