Product Overview

Huangang hand lay-up FRP fiberglass sewage cover plate is high-performance anti-corrosion flat panel specially developed for municipal wastewater and sewage treatment facilities, manufactured in Henan, China with handmade paste molding process. The raw material is reinforced FRP/GRP fiberglass composite, which delivers far better acid, alkali and sewage erosion resistance than metal plates and plastic boards. The finished fiberglass flat sheet retains its original smooth composite surface without additional polishing or coating processing. We support full customization including panel size, thickness, cutting shape and arbitrary customized colors. Every FRP sewage cover plate undergoes strict layer compaction inspection during hand paste production to ensure uniform internal fiber distribution and stable load-bearing performance. It is widely applied as sewage tank cover, drainage trench cover, sewage pool walkway plate and manhole cover in wastewater treatment plants, chemical factories, municipal road drainage and environmental protection engineering.

Core Product Advantages

1. Mature Hand Lay-Up Paste Molding Technology

   Manual layered fiber and resin lamination ensures tight internal combination, high impact resistance and stable load bearing capacity for long-term pedestrian and equipment pressure.

2. Outstanding Sewage & Chemical Corrosion Resistance

   FRP fiberglass composite will not rust, oxidize or degrade under long-term immersion in acid, alkali, sewage and chemical wastewater, far longer service life than steel or plastic covers.

3. Full Multi-Dimensional Customization Support

   Customizable panel length, width, thickness, edge shape and surface color, match different sizes of sewage tanks, drainage ditches and manhole openings in various projects.

4. Eco-Friendly Non-Toxic Composite Material

   Low odor, no harmful heavy metal precipitation, meet environmental protection discharge standards for sewage treatment industrial facilities.

5. Natural Original Smooth Surface

   No secondary surface coating required, anti-slip flat surface can be processed with anti-skid texture on demand, self-cleaning against sewage sludge adhesion.

6. Lightweight High Load-Bearing Performance

   Much lighter than iron and steel cover plates while maintaining enough bearing strength, easy to transport, install and lift for daily sewage pool maintenance.

7. Low Long-Term Maintenance Cost

   No regular anti-rust paint or anti-corrosion coating maintenance needed, effectively reduce later operation and upkeep expenditure of sewage treatment factories.

8. Wide Environmental Engineering Compatibility

   Suitable for urban municipal sewage plants, chemical wastewater workshops, residential community drainage ditches, rural sewage treatment tanks and industrial waste liquid storage pool cover plates.
