Composite resin rain grate (also known as polymer composite / fiberglass reinforced plastic rain grate) is a core component of the drainage system in municipal roads, parks, factories, etc. It is made of unsaturated polyester resin + high-strength glass fiber + mineral fillers, with a built-in steel reinforcement framework, and is formed through a one-time high-temperature and high-pressure molding process. Compared to traditional cast iron grates, it has multiple advantages such as light weight, high strength, corrosion resistance, anti-theft, low noise, and aesthetic appeal. It is the preferred solution for modern drainage projects.
Base material combination: The main body is corrosion-resistant unsaturated resin, with three-dimensional glass fiber reinforcement, filled with heavy calcium and other mineral fillers, and a steel reinforcement framework added at the bottom to ensure a balance of strength and toughness;
Molding process: High-temperature and high-pressure molding for one-piece formation, without secondary assembly, with a dense structure, high dimensional accuracy, and extremely small joint gap between the cover and the seat;
Surface treatment: Anti-slip texture (stripes / dots), customizable in various colors such as green, gray, and black, and some can be made to resemble stone texture, suitable for different road styles. Application
Municipal roads, sidewalks, squares, parks;
Residential communities, underground garage entrances and exits;
Chemical plants, electroplating plants, coastal areas and other highly corrosive environments;
Outdoor drainage of schools, hospitals, commercial complexes.
