Galvalume Steel

Alliance Metal Products offers the highest quality galvalume steel products.

GALVALUME sheet steel is a 55% Al- 45%Zn coated sheet steel product that is ideally suited for most types of roofing and siding applications. Other industries include unexposed automotive parts, appliances and miscellaneous applications like furniture, outdoor cabinetry, computer cases, gutters, pipe, etc. Even in the most aggressive acid rain environments, the 55 % Al-Zn coating continues to provide protection long after the corrosion protection of ordinary zinc coatings has been exhausted. This means that the 55% Al-Zn coating will provide a minimum of twice the expected life as hot-dip galvanized coatings of the same coating thickness. Based on 30-year atmospheric test results, it is estimated that Galvalume sheet will outlast G90 galvanized by two to four times in marine, industrial and rural atmospheres. When compared to aluminum coated sheet steel, Galvalume sheet has superior corrosion resistance at sheared edges.

Salt Spray Corrosion Resistance: With cut edges protected, the coating on Galvalume sheet steel lasts five to ten times longer than the coating on G90 galvanized. In salt spray tests conducted with bare cut edges exposed, the corrosion resistance is typically three to four times that of G90 galvanized.

Paintability

Prepainted Galvalume sheet is an ideal product for many applications where the aesthetic appearance of a painted product is desired along with excellent atmospheric corrosion resistance. Such applications include pre-engineered metal buildings, architectural panels, roofing and siding, and other building components.
