Product Introduction
The solar ground mounting structure is made of ZAM steel, which is short for Zinc Aluminum - Magnesium coated steel. This is a newly developed corrosion - resistant coated steel material. The coating layer of ZAM steel mainly consists of zinc, approximately 11% aluminum, 3% magnesium, and trace amounts of silicon. It is this particular combination of elements that imparts ZAM steel with its unique properties.

What are the advantages of using ZAM steel in solar ground mounting structures?

Superior Corrosion Resistance
Ideal for Harsh Environments: Solar ground mounting structures are often exposed to various outdoor environments. ZAM steel's unique alloy composition forms a dense and stable oxide film on the surface. This enables it to resist corrosion from factors such as moisture, salt spray, and chemical substances in the air, especially in coastal areas with high salt content or industrial areas with poor air quality.
Long-Term Protection for Cut Edges: During the installation of solar ground mounting structures, ZAM steel may be cut or processed. The magnesium in its coating reacts with oxygen in the air to form magnesium oxide, which fills the gaps and microcracks in the coating, effectively preventing corrosion from occurring at the cut edges and prolonging the service life of the structure.
High Strength and Good Formability
Ensured Structural Stability: ZAM steel has high strength and excellent toughness. It can withstand the weight of solar panels and various external forces such as wind and snow, ensuring the stability and safety of solar ground mounting structures.
Easy Installation and Processing: The good formability of ZAM steel allows it to be easily bent, punched, and welded during the manufacturing and installation of solar ground mounting structures.
Good Cost-Effectiveness
Reduced Material and Maintenance Costs: Due to its excellent corrosion resistance and high strength, ZAM steel can use a relatively thinner coating layer and steel plate thickness to achieve the same or better performance as other materials, reducing material costs. Moreover, its long service life and low corrosion rate significantly reduce maintenance and replacement costs during the use of solar ground mounting structures.
Long-Term Economic Benefits: Although the initial purchase price of ZAM steel may be slightly higher than that of some ordinary steel materials, considering the comprehensive factors of long-term use, low maintenance costs, and high reliability, using ZAM steel in solar ground mounting structures can bring better economic benefits in the long term and help reduce the overall cost of solar power generation projects.
Excellent Self-Healing Property
Automatic Repair of Coating Damage: When the coating of ZAM steel is scratched or damaged to a certain extent, the alloying elements in the coating can react with the surrounding environment to form a new protective film, which has a certain self-healing ability. This can delay the corrosion process of the steel substrate and maintain the integrity and performance of the solar ground mounting structure.
Good Compatibility with Solar Panels
Electrochemical Compatibility: ZAM steel has good electrochemical compatibility with the materials of solar panels. It can avoid electrochemical corrosion caused by different electrode potentials when in contact with solar panels, ensuring the stable operation of the entire solar power generation system and prolonging the service life of solar panels.
Environmentally Friendly
Low Carbon Emissions: The production process of ZAM steel requires relatively less energy and produces relatively fewer pollutants compared to some traditional anti-corrosion steel materials. Its use in solar ground mounting structures is in line with the development trend of the solar energy industry towards environmental protection and sustainability.
