Invented by Bethlehem Steel in 1972, the patented Galvalume manufacturing process is similar to galvanization but with aluminum and silicon added to zinc. As the coating dries, patches of aluminum and zinc molecules coalesce into a pattern across the surface of the sheet. The aluminum areas provide corrosion resistance, while the zinc provides galvanization protection. The small amount of silicon helps the coating adhere to the underlying metal, even when cut or rolled into the corrugated shape.
Galvanised MOC compare
Coating thicknessThe thicknesses of the Galvalume are approx 1 mil thick. Its manufacturing includes the hot-dip process, and basically, thickness difference depends on the coating.
NotesExtra corrosion resistance
Service Lifeat least TWICE the service life of traditional zinc-coatings
