SMC Composite Manhole Cover

Wet markets, supermarket outdoor walkways, city plazas, and parks usually have high foot traffic. These areas often remain wet and may contain oil residues, creating slip risks during rainy or snowy weather. Traditional covers may have smooth surfaces that are not suitable for these demanding environments. Our Dingjian SMC composite manhole cover is designed to improve walking safety in wet and high-traffic areas. The item number is 50030030, with 20mm and 30mm thickness options available. The material is SMC composite, with an A15 load rating and a 5 kN capacity. This cover is designed for crowded areas and helps provide a safer walking surface on wet and oily floors.

SMC is the base material used for this SMC composite manhole cover. SMC stands for sheet molding compound. It is pressed at high temperatures to create a strong and rigid structure. Compared with standard resin composites, SMC offers better mechanical performance, surface hardness, and wear resistance. In environments such as wet markets with frequent foot traffic and friction, SMC helps maintain surface durability. It resists surface wear and peeling during long-term use. The anti-slip particles are integrated during the molding process and bond firmly with the material, preventing them from falling off during daily operation.

Oil and chemical resistance are important features for wet markets and supermarkets. Drainage water in these areas may contain oil, food ingredients, cleaning agents, and other substances. Some materials may degrade after long-term exposure to these liquids. SMC composite materials provide excellent chemical resistance. They help prevent softening, discoloration, and strength loss caused by oil or chemical contact. The noise-reduction feature is also valuable in busy public areas. Compared with metal covers, composite materials reduce impact sounds and create a quieter walking environment.
