1.Aluminum solar racking. Its main feature is light weight, which is just about one third of the weight of carbon steel. The surface is anodized, forming a dense oxide film protective layer to prevent oxidation, it is highly corrosion resistant. Moreover, aluminum alloy has a recovery rate of 65% after 25 years service life, which is environmentally friendly and recyclable. In terms of production and processing, aluminum profiles can be easily processed into various specification through cutting, punching, drilling, and other processes, making it more flexible and easy to install. Therefore, aluminum solar racking is suitable for roof with poor load-bearing or areas with severe salt damage and strong corrosion.

2.Carbon steel solar racking. Steel racking system has high strength and high bearing capacity. Usually, the surface is hot-dipped galvanized, which can ensure a 25 years service life under normal conditions, but it needs regular maintenance. Therefore, when the strength requirements are relatively high and the actual span is relatively large, it is recommended to select steel solar racking.

3.ZAM Steel solar racking. Compared with traditional hot-dipped galvanized carbon steel, it performs better corrosion resistance, property is 10-20 times better than galvanized steel, and the service life can reach more than 30 years. It also features self-healing performance, the cutting surface can be self healing without rusting, and can be welded, bending or cutting during installation, easy to process.
