Fiberglass reinforced plastic (FRP) sealed cover is a type of cover made from FRP. When considering comprehensively, FRP lids hold a significant position. Although they may not match some metal lids in terms of strength, their corrosion resistance is far superior to that of metal lids. In terms of load-bearing capacity, they outperform wooden and plastic lids, and their design flexibility and safety performance are also far superior to the aforementioned lids.
Performance:
1. Outstanding wear and slip resistance: Anti-slip and wear-resistant treatments are applied during the manufacturing process. Its slip and wear resistance far exceeds that of common metal, wooden, and plastic lids.
2. Excellent sealing performance and high safety: Compared to metal lids with poor corrosion resistance and wooden lids with inferior materials, the glass fiber reinforced plastic sealing cover offers superior sealing. It also features non-conductive, non-conductive, and high corrosion resistance.
3. High-temperature resistance and strong flame retardancy: All fiberglass products possess 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, which is an environment conducive to chronic corrosion. Metal lids left in humid air for extended periods 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 lids have a service life of about 5 years, while wooden lids have a lifespan of only about 3 years.
Features:
One. Our glass fiber reinforced plastic (GFRP) sewage covers are highly corrosion-resistant: they possess resistance to a variety of corrosive gases and liquids such as acids, alkalis, organic solvents, and salts, making them highly applicable in corrosion prevention. Depending on the specific requirements of the application, the GFRP sealing covers can economically be made with para-phenylene, meta-phenylene, or vinyl ester resins as the matrix material.
2. Lightweight and High-Strength: The density of glass fiber reinforced plastic (GFRP) grating does not exceed 2, and the GFRP cover plate is only 1/4 the thickness of steel and 2/3 that 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 ordinary 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: Resistance to aging: Life span of over 50 years.
Five, our fiberglass sealed covers offer high safety: excellent electrical insulation, no breakdown at 10KV voltage; non-magnetic, suitable for equipment sensitive to magnetism; the special structure of our fiberglass grating covers also features anti-slip and fatigue resistance.
