KaiZM? galvanized aluminum-magnesium steel products were originally developed to replace some stainless steel use scenarios. Fujian Kaijing independently developed Aurora series of zinc, aluminum and magnesium (KaiZM?), which is a eutectic structure formed by high temperature curing of zinc, aluminum and magnesium. A dense layer of super coating is formed on the surface of the steel plate to effectively prevent corrosion. Zinc, aluminum and magnesium products are a new type of environmental protection metal materials, widely used in the field of photovoltaic support, new infrastructure, new energy and so on.
