Glass fiber reinforced plastic (GFRP) arch covers are environmentally friendly equipment made from GFRP using a unique manufacturing process. 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 have wide applications in industries, municipal, construction, and agricultural sectors, such as covering water pools, roofs, and fish ponds.

Glass fiber reinforced plastic (GFRP) arch covers offer numerous advantages. Firstly, they are lightweight yet strong, easy to install, and their density is only 1/3 to 1/4 of steel, significantly reducing transportation and installation burdens. Secondly, GFRP arch covers are corrosion-resistant and have excellent insulation properties, eliminating concerns about corrosion over long-term use and reducing maintenance costs for equipment. Moreover, they provide excellent thermal insulation, as the low thermal conductivity of glass fiber ensures good insulation without the need for additional thermal insulation structures.

The glass fiber reinforced plastic arch cover is composed of an outer layer, a structural layer, and an inner layer in structure. The outer layer is resistant to aging and ultraviolet rays, featuring an aesthetically pleasing color that meets industrial environmental requirements. The structural layer bears the load pressure. The inner layer, however, needs to be resistant to corrosion, temperature, and prevent leakage. Additionally, the cover is usually divided into smaller sections for easy disassembly and manual handling. Proper sealing connections should be made between the individual sections and between the cover and the pool's surface to prevent odor leakage.
