Aluminum-Magnesium-Zinc coated steel is a new type of highly corrosion-resistant coated steel sheet with a coating composition consisting of zinc as the main substrate in combination with aluminum (about 11%), magnesium (about 3%) and a trace amount of silicon. Adding Al, Mg, and Si. Primary Composition: The base material is typically steel plate coated with a ternary alloy layer of zinc, aluminum, and magnesium. Although termed "zinc-aluminum-magnesium supports," their core structure relies on the properties of the coating. Density and Weight: Density approximately 2. According to the 'NB/T 10115—2018 Technical Code for PV Mounting Structure Design', the service life of PV supports should not be less than 25 years, which. This is why professionals rely on ZM Ecoprotect ® Solar: Our high-quality zinc-aluminum-magnesium-coated steels for effectively protecting high-performance stud framing from corrosion. For foreign clients seeking reliable solar mounting solutions, Zn-Mg-Al-equipped solar mounting delivers unmatched value across diverse. Among the various materials available, Zinc-Aluminum-Magnesium (Zn-Al-Mg) plates are emerging as the material of choice for PV mounting systems, thanks to their remarkable durability, strength, and versatility. Here's why Zn-Al-Mg plates are increasingly becoming an essential component in PV.
