Product Description
Pre-Painted Galvalume Sheets combines both the galvanic protection of Zinc and barrier protection of Aluminium. The Zinc-rich region is locked in tiny pockets within the Aluminium-rich matrix. The Aluminium in the coating complements the corrosion resistance process by providing barrier protection, reducing the rate of dissolution of the Zinc from the Zinc-rich areas of the alloy layer. The Zinc-rich areas are important as they provide the product with galvanic protection. In service, galvanic action causes zinc compounds to automatically build up at cut edges and scratches by an electrolytic reaction when water or moisture is present. These slow the rate at which the surrounding coating is consumed around damaged areas. This effect is sometimes referred to as the “self-healing” property of coatings containing zinc. This has been tested by removing coating of similar thickness from BUILDSTARâ„¢ galvalume steel and galvanized sheet down to the steel base, using scribe marks ranging from 0.40mm to 4.0mm in width.
