The Earth Pit Cover is typically made from durable materials such as high-grade polypropylene, HDPE (High-Density Polyethylene), concrete, FRP (Fiber Reinforced Polymer), cast iron, or galvanized iron. Polypropylene and HDPE are favored for their chemical resistance, high melting points (160-171 °C), and non-conductive properties, making them safe and weather-resistant applications.
