The explosion-proof composite load-bearing manhole cover for gas stations is made of fiberglass reinforced plastic (SMC composite material) through high-temperature and high-pressure one-time molding. This product features high strength (capable of withstanding the passage of a 250T large truck), static electricity conduction, double-layer sealing and waterproofing, flame retardancy, high hardness, light weight, wear resistance, corrosion resistance, anti-aging, beauty, anti-theft and environmental friendliness. All indicators have been tested by the national authoritative department and have met the national standards. It is the most ideal substitute for cast iron manhole covers.

Product features
1. Load-bearing capacity: This product is made of high-molecular chemical composite materials. Formed by high-temperature molding, it features high strength, with a single cover capable of withstanding a pressure of 40 tons and able to withstand the passage of a 250T large truck, leading the industry.
2. Corrosion resistance and anti-aging: The product has been tested by the National Chemical Building Materials Testing Center and has obvious acid and alkali resistance and corrosion resistance. The anti-aging index reaches level three or above, and the service life is over 30 years.
Iii. Sealing and Waterproof Performance: This product adopts a double-sealed waterproof design, which can prevent water from entering the operation well and also prevent oil and gas from overflowing, playing a role in ensuring safety.
Fourth, convenient and aesthetically pleasing. The weight of products of the same specification is only one third of that of cast iron manhole covers, which brings great convenience to installation and maintenance.
