What material is best suited for seismic supports in solar power plants?

The construction of photovoltaic power plants involves high costs and long lead times. As the core load-bearing components, mounting structures—if corroded or structurally inadequate—can, at best, reduce power generation efficiency and, at worst, lead to collapse accidents. Many buyers struggle with material selection: should they choose standard hot-dip galvanizing or zinc-aluminum-magnesium?

Zinc-Aluminum-Magnesium Alloy: The New Benchmark for Corrosion Protection in PV Mounting Systems

Hebei Zegui Metal Products Co., Ltd. specializes in zinc-aluminum-magnesium C-channel steel, which features a ternary zinc-aluminum-magnesium alloy coating. Its corrosion resistance is 3–5 times that of traditional hot-dip galvanizing, making it particularly suitable for salt fog and high-humidity environments. Its self-healing properties at cut edges effectively extend the mounting system’s lifespan to over 25 years, perfectly aligning with the full lifecycle of a solar power plant.

Load-Bearing and Seismic Resistance: Safety Guaranteed by National Standards

Our seismic-resistant brackets are manufactured in strict accordance with the GB/T 37267 standard and have passed seismic simulator tests, with the ability to withstand seismic intensity of 8 degrees. The zinc-aluminum-magnesium alloy combines high strength with lightweight properties, reducing the load on PV arrays and lowering foundation costs.

Applications: Comprehensive Coverage from Rooftops to Mountainous Areas

Whether for distributed rooftop power plants, centralized ground-mounted power plants, or agri-solar projects, Hebei Zegui can provide customized solutions. Our products have been deployed in photovoltaic poverty alleviation projects across Hebei, Shandong, and other regions, earning consistent praise from customers.

Direct from the Factory: Source manufacturer eliminates middlemen

Hebei Zegui Metal Products Co., Ltd. operates a fully automated cold-forming production line with a daily capacity of 50 metric tons and supports non-standard customization. Manager Qiao Yukang (Phone: 15097692990) guarantees that all products undergo 100% inspection before leaving the factory and come with a warranty certificate and technical support.
