Cable trench concrete covers, made by high-temperature molding, offer aesthetic appearance, high strength, resistance to acids and alkalis, corrosion resistance, excellent fire performance, light weight, and no need for painting maintenance. 1. Corrosion resistance: No severe corrosion occurs in water or general acids and alkalis. 2. High strength: No cracks appear after hammering tests, with a strength much higher than glass fiber reinforced plastic. 3. Light weight: Due to the low density of the material, it is significantly lighter than steel bars of the same specification. 4. Good fire performance: The material is non-combustible, making it flame-retardant. 5. Aesthetics: The surface, after special treatment, features exquisite appearance and diverse designs.
