Made of high-quality steel with hot-dip galvanizing treatment, it is corrosion-resistant and acid and alkali-resistant. The large-size helical blade design significantly increases the contact area with the soil, distributing the load and reducing the screwing resistance, making it suitable for various geological conditions such as sandy soil and clay. Construction is quick, and the top can be fitted with flanges or nuts for connection, making it an efficient foundation support choice for photovoltaic power stations, wind turbine bases, communication towers, and other applications.
