Product Description:

The SMC manhole cover is a modern solution engineered using Sheet Molding Compound (SMC), a high-performance composite material composed of unsaturated polyester resin, fiberglass, mineral fillers, and various functional additives. Manufactured under high temperature and pressure, the cover forms a dense, one-piece structure with excellent mechanical and chemical properties.

Key Features:

1. Lightweight yet Strong:
   SMC covers are approximately 60% lighter than traditional cast iron covers, significantly reducing transportation and installation costs. Despite their low weight, they provide 4–5 times the strength of standard covers and fully comply with EN124 load classes A15, B125, C250, and D400.

2. Excellent Corrosion Resistance:
   The material resists chemical corrosion, moisture, and acidic environments, making it suitable for long-term use in harsh conditions without performance degradation.

3. Anti-Theft Design:
   Unlike metal covers, SMC manhole covers have no scrap value, effectively preventing theft and ensuring the security of public infrastructure.

4. Superior Sealing Capability:
   Optional sealing gaskets prevent leakage of toxic gases from underground systems while minimizing noise and odor pollution—ideal for residential and urban areas.

5. Weather Resistance:
   The cover withstands extreme temperatures ranging from -50°C to +160°C without warping or aging, making it suitable for use in a wide range of climates.

6. Anti-Slip Surface:
   A specially textured surface ensures a high level of slip resistance, improving pedestrian and vehicle safety.

Applications:

SMC manhole covers are widely used in municipal roads, residential complexes, industrial parks, airports, docks, and parking lots. They are ideal for covering utility access points for water supply, drainage, electricity, gas, and telecommunications systems.

Available Sizes:

Standard and custom sizes are available, including round, square, and rectangular shapes. Customization is offered based on your design and project requirements.

Installation & Maintenance:

Thanks to their lightweight design, SMC manhole covers are easy to install and require minimal labor. They need very little maintenance—just regular inspections to check the surface and seal conditions.
