The 1200×500 composite cable trench cover plate is designed to provide long-term protection for power cables, communication pipelines, and underground utility channels. Manufactured with high-strength SMC/FRP composite material, this trench cover delivers excellent mechanical performance, corrosion resistance, and safety.
It is widely used in urban road cable trenches, industrial plants, substations, telecom facilities, and municipal infrastructure projects.
This model features optimized weight, superior durability, and anti-theft properties, making it an ideal replacement for traditional cast-iron trench covers.
The cover plate supports heavy-duty loads (optional C250 / D400 / E600), suitable for vehicle lanes, industrial roads, and logistics areas.
Its reinforced composite structure ensures long-term stability without cracking or deformation.
Compared with cast iron, composite trench covers weigh 30–50% less, significantly reducing labor intensity and improving installation efficiency on large-scale projects.
The FRP/SMC material is resistant to rust, chemical corrosion, moisture, and UV exposure—ideal for coastal areas, chemical industries, and outdoor environments.
The composite material provides full electrical insulation, preventing sparking and improving safety in power substations and communication rooms.
Non-metallic composite plates have no recycling value, greatly reducing theft incidents and maintenance costs for municipal clients.
Thanks to its stable material properties, the product typically offers a 20-year+ service life, even in challenging environments.
