1. The government attaches great importance to municipal greening. Greening has been a widespread project across the country. It starts from large cities, develops to small and medium cities, and finally enters the urban and rural markets. Therefore, the future development of FRP tree pit covers cannot be limited.
2. The product quality of the FRP tree pit cover can withstand the test. The long-term development of a product in the market shows that this product has been widely accepted and its quality can stand the test. Features of FRP tree pit cover:
1). Corrosion resistance: It has excellent corrosion performance in many gas and liquid media such as acid resistance, alkali resistance, organic solvent and salt resistance, and has incomparable superiority in the field of anti-corrosion. According to the requirements of actual use occasions, o-phthalic, isophthalic, and vinyl resins can be economically selected as the matrix material.
2). Lightweight, high strength, and easy to cut and install. Because it is a composite of resin and glass fiber, its density is less than 2 kilograms per cubic decimeter, which is only 1/4 of steel and 2/3 of aluminum. Its strength is 10 times that of rigid PVC, and its absolute strength exceeds that of aluminum and ordinary steel. Its light weight can greatly reduce the foundation support, thereby reducing the material cost of the project. Its cutting and installation are simple, without hot and large lifting equipment, only a small amount of labor and electric tools, so that the installation cost is also greatly reduced.
3). Aging resistance: The service life of the glass fiber reinforced plastic tree pit cover is more than 50 years.
4). Flame-retardant: The flame propagation rate of ordinary flame-retardant grille (ASTM E-84) does not exceed 25; the flame propagation rate of advanced flame-retardant vinyl grille does not exceed 10. The oxygen index is not less than 28 (GB 8924).
5). Safety: It has excellent electrical insulation, no breakdown under 10KV voltage; non-electromagnetic, can be used on magnetically sensitive equipment; the special structure of the glass fiber reinforced plastic tree pit cover also has the characteristics of anti-skid and anti-fatigue.
6). Uniform color inside and outside. And the color can be chosen arbitrarily. The color can be customized according to the customer's requirements, and the environment of the production site can be improved.
7). It has good comprehensive economic benefits.
8). The glass fiber reinforced plastic tree pit cover can be designed strongly. The size is flexible and diverse, and the size is stable.
3. The product price of FRP tree pit cover can be recognized by the public. Both urban greening and urban greening use glass fiber reinforced plastic tree pit cover, indicating that the price of glass fiber reinforced plastic tree pit cover is a price acceptable to the public, and only moderate price and high quality can be accepted at all levels.
