MAC steel — the new material for solar racking
With the popularization and wide application of solar power stations, in response to more severe corrosive environments and increasingly stringent environmental protection requirements, MAC steel have emerged as a new type of solar racking material. With its multiple advantages, it can perfectly replace traditional hot-dip galvanizing steel and be used in large-scale solar ground power plants. MAC steel is formed by high-temperature curing of zinc (Zn), aluminum (Al) and magnesium (Mg). The magnesium (Mg) component in the coating is beneficial to promote the formation of a very stable and well-structured fine protective film, so that the MAC steel possesses excellent corrosion resistance. Multiple advantages of MAC a.High corrosion resistance Due to the dense protective film on the surface, MAC steel has excellent corrosion resistance, which is about 10 times than that of hot-dip galvanized steel. b. Self-healing performance The coating composition around the cutting surface will
