SMC composite manhole cover is lightweight, low in price, and aesthetically pleasing in appearance. It can be colored at will, and is easy to install and maintain. Because it has no recycling value, it completely solves the problem of anti-theft. Anti aging agents such as ultraviolet absorber are added to make it wear resistant and service life doubled. Instead of using a steel skeleton for reinforcement, it is reinforced with fiberglass composite, which has compressive, bending, and impact strength, toughness, and can reach the six load levels of national standards A15, B125, C250, D400, E600, and F900. Installing smart devices will not shield the signals of smart devices, making it the preferred equipment carrier for smart manhole covers. And it is acid and alkali resistant, corrosion resistant, wear-resistant, and resistant to vehicle rolling without noise. The unique design of DSD Composite manhole covers solves the problems of traditional manhole covers such as running, jumping, and flipping.
