720 Round Composite Manhole Cover
The 720 round composite manhole cover is professionally designed for heavy-duty vehicle passage, with outstanding rustproof, anti-corrosion and anti-theft performance. As a high-quality D400 manhole cover, this composite manhole cover adopts advanced SMC material, making it widely applicable in municipal, road and industrial scenarios.
Advantages of SMC Manhole Cover & Composite Manhole Cover
① The SMC manhole cover features a smooth and attractive appearance, with multiple color options including black, gray, green, yellow and red. The surface of this 720 round manhole cover is designed with anti-slip delicate patterns and lines, and the surface of the composite manhole cover can be customized to meet different project needs. As a reliable D400 manhole cover, its appearance design combines practicality and aesthetics perfectly.
② Lightweight structure is a core advantage of the composite manhole cover. The SMC manhole cover weighs only 1/3 of cast iron or concrete manhole covers, so this 720 round manhole cover is easy for single-person installation and handling. Such a lightweight D400 manhole cover brings convenience to daily inspection and maintenance, and effectively reduces the risk of labor injuries during construction.
③ The SMC manhole cover has excellent toughness and is not easy to crack. This composite manhole cover strictly complies with EN 124-1:2015 and EN 124-5:2015 standards, and the load grade can reach A15/B125/C250/D400/E600/F900. As a standard D400 manhole cover, the 720 round manhole cover can bear heavy vehicle loads stably, ensuring long-term safe use.
④ The composite manhole cover has superior anti-corrosion and anti-aging properties, adapting to various harsh weather conditions. The SMC manhole cover supports a temperature range of -50~160℃, with strong resistance to acid, alkali, salt and organic solvents, and a low thermal expansion coefficient of 12×10⁻⁶/℃. This 720 round manhole cover maintains stable performance in complex environments, fully reflecting the advantages of a high-performance D400 manhole cover.
⑤ Compared with metal materials, the SMC manhole cover has excellent insulation and dielectric properties. The optimized formula makes this composite manhole cover meet the anti-static requirements of SJ/T11159-1998 in the electronics industry. The 720 round manhole cover is rust-free, has no recycling value and low noise, making the D400 manhole cover more suitable for special places such as industrial parks and power facilities.
⑥ The SMC manhole cover has a long service life of no less than 30 years. High-performance resin, fiberglass and professional production technology enhance the internal bonding of the composite manhole cover, giving it high fatigue strength. The 720 round manhole cover, as a durable D400 manhole cover, maintains stable load-bearing performance under long-term frequent use.
⑦ The SMC manhole cover is environmentally friendly with halogen-free and non-toxic raw materials. The reasonable structure of the composite manhole cover eliminates the noise caused by the collision between the cover and the frame. The 720 round manhole cover, as a green and safe D400 manhole cover, meets the environmental protection requirements of modern municipal engineering.
