Mammut Industrial Group Sandwich Panel

Sandwich panel is a combination of different materials with an intermediate layer made of polyurethane foam, rock wool or other stuff. Sandwich panel is surrounded from both sides by metal sheets (Aluzinc, galvanized …). In terms of external layer, sandwich panels are divided into several types: one side sheet one side foil / each side of foil / each side of nylon / one side sheet one side paper. Metal coating of Mammut Industrial Group sandwich panel has a high strength and corrosion resistance property. Aluzinc sheet is of carbon steel with a coating of an alloy consisting 55% aluminum, 43% zinc and 16% silicon. Aluminum increases corrosion resistance of the sheet and zinc enhances its abrasion properties.
