EPD: Metal coated steel sheets and coils, 7850 kg/m3 (SSAB (2023))
SSAB specializes in materials for demanding applications where high strength and formability are needed for weight savings and increased durability. Metal coated steels are used in several applications and by many sectors including: • Building and construction; roof, cladding, drainage, frames, load-bearing sheets, beams and sections • Domestic and electrical appliances; white, brown and gray goods • Heating, ventilation and air conditioning equipment; air ducts, housings and valves • Light engineering; frames, trays, cabinets and housings • Automotive industry • Tubes and sections industry Metal coated steels can be processed in many ways including bending, deep drawing, stretch forming, roll forming, welding, cutting and painting. A metal coating protects the steel from corrosion in two ways. It serves as a protective layer keeping oxygen and water away from the steel, but it also acts as a cathodic protection. This means that at cut edges or in case of damages through the zinc coating, the zinc will sacrifice itself and react to form protective compounds and block further corrosion processes. The zinc coating covers the steel on both sides.
