As the requirements for environmental protection and odor control continue to rise worldwide, wastewater treatment plants are increasingly adopting durable, corrosion-resistant, and fully customizable cover systems. At Hebei Leihong Fiberglass Technology Co., Ltd., we specialize in manufacturing GRP/FRP covers in various shapes, including arched panels, circular tank covers, and large-span modular structures designed specifically for sewage tanks, sludge tanks, and wastewater process basins.
Our GRP covers are made from fiberglass-reinforced composite materials that deliver long service life even in highly corrosive wastewater environments. Unlike metal covers that easily corrode or concrete covers that absorb odor, GRP offers excellent chemical resistance, lightweight structure, and stable performance under outdoor conditions. This makes it one of the most reliable solutions for wastewater treatment, odor control, and plant upgrading projects.


One of the major advantages of Leihong's product line is customization. Every wastewater tank is different in size, layout, and operational needs. To match these requirements, our arched and circular covers can be fully tailored based on diameter, height, curvature, panel width, surface finish, color, and reinforcement configuration. Whether it is a small treatment pond, a medium-sized sludge tank, or a large-scale municipal wastewater basin, our engineering team provides precise and adaptable solutions.
The circular GRP tank covers are especially suitable for round sludge tanks, anaerobic tanks, thickener tanks, and hydrolytic acidification units. Their modular design allows fast installation, reduces downtime, and provides excellent sealing to support odor control systems. Clients often pair these covers with spray towers, scrubbers, GRP pipes, and biofilters to create a complete odor management solution.
Arched GRP panels are widely used for rectangular basins, equalization tanks, and open-channel wastewater facilities. These panels can be manually installed, offer safe access when maintenance openings are required, and maintain structural stability with minimal weight. GRP materials also resist UV aging, moisture, and chemical exposure, ensuring long-term reliability.
Leihong has provided customized GRP covers for wastewater plants in Southeast Asia, the Middle East, South America, and Africa, supporting odor control initiatives and environmental upgrades. Customers choose our covers because they are lightweight, strong, corrosion-resistant, and economical over the long term. Whether for industrial wastewater, municipal sewage stations, or agricultural livestock waste tanks, GRP covers offer an efficient and sustainable solution.
For facilities looking to upgrade odor control systems, reduce emissions, protect equipment, and maintain a cleaner working environment, Leihong's arched and circular GRP covers provide a proven and customizable option.
