Glass fiber reinforced plastic (GFRP) sealed covers are covers made from GFRP. When considering all aspects, GFRP lids hold a significant position. Although they may not match the strength of some metal lids, their corrosion resistance is far superior. In terms of load-bearing capacity, they outperform wooden and plastic lids, and their design flexibility and safety performance are also superior to the aforementioned lids.
Performance:
1. Outstanding wear and slip-resistant properties: Anti-slip and wear-resistant treatments are applied during production. Its slip-resistant and wear-resistant performance far exceeds that of general metal, wood, and plastic lids.
2. Excellent sealing performance and high safety: Compared to metal lids with poor corrosion resistance and wooden lids of inferior quality, the glass fiber reinforced plastic sealing cover offers superior sealing. It also boasts a multitude of features such as non-conductivity, non-heat conductivity, and high corrosion resistance.
3. High-temperature resistance and strong flame retardancy: All glass fiber reinforced plastics (GFRP) products exhibit strong flame retardant properties, primarily due to the resin used in their manufacturing. Although there are various types of resins, high-temperature resistance is a fundamental property shared by all.
4. Excellent aging and corrosion resistance: Aging is a form of corrosion, more accurately described as chronic corrosion, such as humid air being an environment of chronic corrosion. Metal lids left in humid air for a long time will gradually corrode, commonly known as rusting.
5. Long service life and high economic benefits: Generally, the service life of glass fiber reinforced plastic covers exceeds 50 years. In contrast, metal covers have a service life of about 5 years, while wooden covers last only around 3 years.
Features:
One. Our fiberglass sewage cover plates are highly resistant to corrosion: featuring resistance to acids, alkalis, organic solvents, and various corrosive gases and liquids, they have a high application rate in the corrosion prevention field. According to the specific requirements of the actual usage environment, the glass fiber seal covers can be economically selected to use biphenyl, m-xylene, or vinyl ester resins as the base material.
Two, Lightweight and High Strength: The density of glass fiber reinforced plastic grating does not exceed 2, and the grating cover is only 1/4 the thickness of steel and 2/3 the thickness of aluminum. Its strength is 10 times that of rigid PVC, and greater than that of aluminum and ordinary steel.
Three, our glass fiber reinforced plastic grating covers are flame retardant: the flame spread rate of standard flame retardant grating (ASTM E-84) does not exceed 25; the flame spread rate of high-grade flame retardant vinyl grating is no more than 10. The oxygen index is not less than 28 (GB 8924).
Four: Aging Resistance: Lifespan of over 50 years.
Five, our fiberglass seal covers offer high safety: excellent electrical insulation, no breakdown under 10KV voltage; non-magnetic, suitable for equipment sensitive to magnetism; the unique structure of our fiberglass grid covers also features anti-slip and fatigue resistance.
