Solar spiral pile is a foundation pile designed specifically for solar power plants, mainly used to fix and support solar panels and their support systems. Solar spiral pile is a steel pile body with spiral blades, which is buried in the soil by rotation to provide stable support.

Steel spiral pile is a type of steel pile widely used in various engineering fields, characterized by excellent strength performance, economic durability, and easy construction. It is a steel pile with a spiral shape. It is usually divided into cylindrical hollow piles and circular or polygonal solid piles. This type of pile, due to its unique spiral structure, has a smoother screwing process in soil and can provide better resistance to pulling and compression.
