Fiberglass cover plates can be used as trench cover plates, drainage cover plates, manhole covers, sewer cover plates, etc. In this article, the editor will explain why fiberglass cover plates are used as manhole covers?
Why use fiberglass cover plates as manhole covers? Because fiberglass cover plates have numerous advantages and meet the material requirements for manhole covers. Advantages of fiberglass cover plate:

1. Strong anti-theft performance: The resin composite manhole cover is made of unsaturated resin, glass fiber and other materials, and steel reinforcement skeleton through special production processes. It is formed by high-temperature grinding and pressing once, and the material has no recycling value. It is very difficult to remove the steel reinforcement (the cost of removing the steel reinforcement exceeds its value), so it has active anti-theft function.
2. High load-bearing capacity: The bottom adopts a special pot bottom structure, which increases the load-bearing area by more than ten times or even tens of times. The continuous reinforcement fiber yarn used ensures that the fiber yarn and glass fiber cloth are integrated from the material, thereby giving the product sufficient load-bearing capacity.
3. Long service life: By using high-performance resin, glass fiber, and special production process formulas, the penetration of resin into glass fiber is ensured, greatly enhancing the adhesion between the two, and preventing internal damage to the material under cyclic loading, thus ensuring the service life of the product and the same superiority as other resin composite manhole covers. Eliminating the drawback of poor adhesion.

4. Beautiful, practical, and high-end: Complex logos and personalized designs with multiple colors can be made on the same manhole cover surface according to the needs of high-end customers, making the patterns delicate and the colors bright and distinct. And various imitation stone surfaces and colors that are the same as various stone pavements can be made according to customer needs.
5. High/low temperature resistance, good insulation performance, strong corrosion resistance: The product is corrosion-resistant and free of metal additives. Can be used in complex, varied, harsh, and demanding environments. The product has been tested by relevant authoritative testing institutions, and has obvious acid and alkali resistance, corrosion resistance, and aging resistance.
6. Environmental protection, anti slip, and low noise: This product does not slip, produce harsh noise, or cause backlash after being crushed by a car. At the same time, due to the light weight of the product and the precise fastening of the cover and seat, it overcomes the problems of “jumping, tilting, ringing, and shifting” of other inspection manhole covers.
