The polyethylene multi-point anchoring plate is a novel engineering protective material made from high-density polyethylene (HDPE) through a special process. Its uniqueness lies in the fact that one side of the plate is a smooth surface, while the other side is evenly distributed with staggered V-shaped anchor nails. This design enables it to form a physical anchoring bond with substrates such as concrete and steel structures, creating a stable composite protective layer.
