Plastic grating for walkways is manufactured using high-density polyethylene (HDPE) or other composite materials known for their resilience against weathering and rot. These gratings are designed to support heavy foot traffic without bending or breaking, ensuring that they remain stable and safe under continuous use. Furthermore, their non-slip surface provides a secure footing even in wet conditions, reducing the risk of accidents.
