Description

Screw Piles (also known as helical piles or ground screws) are advanced foundation systems consisting of steel shafts with helical plates that are mechanically screwed into the ground. They are widely used in construction and photovoltaic (PV) mounting systems as a fast, efficient, and environmentally friendly alternative to traditional concrete foundations.
Manufactured from high-strength steel (such as Q235 or Q355) and typically treated with hot-dip galvanizing or Zinc-Aluminum-Magnesium (Zn-Al-Mg) coatings, Screw Piles offer excellent durability and corrosion resistance for long-term outdoor use.
