    Key points about solar steel structure galvanized square steel pipes:

    Perforated galvanized square and rectangular tubes are specifically designed for the photovoltaic (PV) sector, with core advantages of high-strength structural support and long-lasting corrosion resistance. Utilizing a hot-dip galvanizing process, the zinc layer thickness reaches 70μm (in compliance with ISO 1461 standards). It has passed the ASTM B117 standard salt spray test for 1000 hours, ensuring stable performance for over 25 years in C5-level corrosive environments, such as coastal areas with high salt spray and industrial pollution.

    The square/rectangular cross-section design, combined with uniform perforation technology, provides excellent bending and torsional mechanical properties while facilitating cable threading and modular installation, significantly reducing construction costs. Compared to traditional angle steel or aluminum alloy solutions, the total lifecycle cost is reduced by over 30%. Additionally, it supports customized dimensions and enhanced galvanization, making it suitable for extreme environments such as deserts, high-altitude areas, and humid heat conditions.
