The lid is divided into smaller sections for easy manual disassembly.2. The individual lids should be sealed together and between the lids and the pool's top surface to prevent odor leakage.3. Excellent corrosion resistance; all resins used are of high-quality, corrosion-resistant varieties.4. Insulation: Due to the low thermal conductivity of fiberglass, the additional insulation structure of this fiberglass equipment is sufficient to achieve the required insulation performance.5. Lightweight and Easy to Install: Glass fiber reinforced plastics (GRP) have a density only 1/3 to 1/4 that of steel, yet offer high strength. As a result, the transportation and installation of GRP equipment are extremely convenient.6. Low Operation and Maintenance Costs: Glass fiber products inherently possess excellent corrosion resistance, eliminating the need for regular anti-corrosion treatments and other maintenance as required for metal products. Clearly, this reduces maintenance costs during the operation of the equipment.
