Although the film thickness is thin, it has about 20 times the corrosion resistance of molten Zn plating.
Galvalume 55 refers to a 55% Al-Zn coating that has 55% aluminum added to improve the corrosion resistance of hot-dip galvanized (zinc-coated) materials. It exhibits extremely excellent corrosion resistance. The reason for this is the high corrosion resistance of the composite corrosion products of aluminum and zinc, as well as the sacrificial corrosion protection effect of zinc, which dissolves to protect iron from rust. It has 5 to 20 times the corrosion resistance of hot-dip zinc coatings. It is optimal for fasteners in roads, civil engineering, construction, railways, power, telecommunications, and chemical plants, particularly against salt damage, de-icing agents, and acid rain.

Company information
The emphasis on corrosion prevention in industries such as steel, shipbuilding, and energy, which support our country's economy, is on the rise, and their share of GNP is significant. Shinko Aluma Co., Ltd. is dedicated to improving technological capabilities and developing human resources to meet the needs of these industries, while also actively addressing today's global challenges such as resource conservation and environmental protection, thereby contributing to the development of society. In 1953, Shinko Aluma successfully established and commercialized the molten aluminum plating method, and has continued to engage in research and improvement to this day. The molten aluminum plating method of Shinko Aluma is trademarked as "Alumer," which has now become the common name for this plating method.
