The cable trench cover plate is made of inorganic composite materials, cement-based materials, and concrete, rpc。 Inorganic composite material cable trench covers are generally around 50 years old, depending on their density, hardness, and other parameters. The cable trench cover plates are made of iron plates and coated with anti rust coating. Because the cable trench has a metal surface and is connected to the ground for shielding purposes.

Based on the usage characteristics of cable trench cover products, a new high-end composite material widely promoted and used internationally is adopted to develop and produce reinforced thermosetting composite cable trench cover plates, completely overcoming many defects of other cover plates. Suitable for different regions, conditions, and development needs, it has the advantages of good corrosion resistance and flame retardancy, high strength, and easy installation.

Recycled resin and polymer based composites: Poor temperature resistance, brittle in winter, prone to expansion in summer, poor applicability, short service life, and higher price than steel fiber reinforced concrete.
Composite resin material, commonly referred to as BMC, mainly uses unsaturated resin, glass fiber short cut, filament, and some fillers, combined with steel reinforcement skeleton. The product has stable performance, strong temperature resistance, acid and alkali resistance, compression resistance, bending resistance, impact resistance, and flame retardancy.
