The glass fiber reinforced plastic (GFRP) seal cover is a type of cover made from GFRP. When considering in terms of overall performance, the GFRP cover holds a significant position. Although it may not match some metal covers in terms of strength, its corrosion resistance is far superior to that of metal covers. In terms of load-bearing capacity, it outperforms wooden and plastic covers, and its design flexibility and safety performance are also much better than those of the aforementioned covers.
Performance:
1. Outstanding wear and slip-resistant properties: Anti-slip and wear-resistant treatments are applied during the manufacturing process. Its slip and wear resistance far exceeds that of ordinary metal, wooden, 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 fiberglass sealed cover offers superior sealing. It also features non-conductive, non-conductive, and high corrosion resistance.
3. High Heat Resistance and Flame Retardancy: All fiberglass products exhibit strong flame retardant properties, primarily due to the resin used in their manufacturing. Although there are various types of resins, heat resistance is a fundamental characteristic inherent in each.
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 an extended period will gradually corrode, commonly known as rusting.
5. Long service life and high economic benefits: Generally speaking, 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 about 3 years.
Features:
One. Our glass fiber reinforced plastic (GFRP) sewage covers are highly resistant to corrosion: They possess corrosion resistance to a wide range of 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 bisphenol A, bisphenol F, or vinyl ester resins as the matrix 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 it exceeds the strength of aluminum and ordinary steel.
Three, our glass fiber reinforced plastic grating covers are flame retardant: the flame spread rate of the ordinary flame retardant grating (ASTM E-84) is no more than 25; the flame spread rate of the 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: Service life of over 50 years.
Five, our glass fiber reinforced plastic (GFRP) sealed 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 GFRP grating covers also features anti-slip and fatigue resistance.
