Glass fiber reinforced plastic (GFRP) arch covers are environmentally friendly devices made by a unique manufacturing process using glass fiber reinforced plastic (GFRP) as the raw material. They are primarily used for covering sewage pools to prevent odor dispersion, ensuring that the exhaust gases in the pool are isolated from the air, and to prevent odors from spreading into the atmosphere. Additionally, GFRP arch covers find extensive applications in industries, municipal, construction, and agricultural sectors, such as covering water pools, roofs, and fish ponds.

Glass fiber reinforced plastic (GFRP) arch covers feature multiple advantages. Firstly, they are lightweight yet strong, easy to install, and weigh only 1/3 to 1/4 of steel, significantly reducing the burden of transportation and installation. Secondly, GFRP arch covers are corrosion-resistant and have excellent insulation properties, ensuring no corrosion concerns over long-term use and reducing maintenance costs for equipment. Moreover, they offer excellent thermal insulation due to the low thermal conductivity of glass fiber, achieving good insulation without additional structures.

The glass fiber reinforced plastic arch covers are composed of an outer layer, a structural layer, and an inner layer. The outer layer is resistant to aging and UV rays, with a beautiful and tasteful color, meeting the requirements of industrial environments. The structural layer bears the load pressure. The inner layer, on the other hand, needs to be resistant to corrosion, temperature, and leakage prevention. Additionally, the covers are typically divided into smaller sections for easy disassembly and manual handling. The individual sections and the connection between the covers and the pool's top surface should be sealed to prevent odor leakage.
