Product Overview

Huangang curved FRP fiberglass cover plate is arch arc composite sealing cover specially designed for industrial sewage tank, wastewater trough and biochemical pool odor sealing, produced in Henan, China via standard hand lay-up fiber laminating molding craft. Multi-layer cross fiberglass hand lay-up structure greatly improves the bending load bearing capacity of the curved panel, can withstand pedestrian walking and light equipment pressure without deformation or cracking. The outer layer adopts smooth gel coat surface treatment, compact and non-porous, effectively resist adhesion of sludge, industrial waste gas and sewage scale, easy to flush and clean daily. The arc curved streamline design accelerates rainwater automatic drainage, avoids water accumulation on the cover surface and prevents water seepage into the tank. Our factory provides precision fixed-length cutting processing service, can cut the curved cover into any matching width and length according to the actual size of the customer's sewage tank, no secondary modification required on construction site. The integral fiberglass resin composite formula has permanent anti-corrosion performance, long-term resistance to industrial acid-base wastewater, hydrogen sulfide corrosive gas and coastal salt fog erosion, solving the rust, rot and leakage defects of metal and concrete cover plates. Widely applied for odor sealing isolation of chemical plant sewage tanks, municipal sewage treatment biochemical pools, printing and dyeing wastewater troughs, electroplating waste liquid storage tanks and all industrial environmental protection construction projects.

Core Product Advantages

1. Stable Hand Lay-Up Multi-Layer Fiber Molding Structure

   Cross laminated fiberglass hand lay-up craft ensures uniform internal fiber distribution, balanced arc bending bearing capacity, safe to walk on without breakage under long-term outdoor load.

2. Smooth Gel Coat Stain-Resistant Surface

   Seamless smooth outer surface prevents sludge, chemical scale and waste gas residue from adhering, quick water flushing to restore clean condition, reduce daily maintenance labor cost.

3. Arch Curved Self-Drainage Streamline Design

   Natural arc radian realizes automatic rainwater outflow, no ponding on cover surface, effectively avoid rainwater infiltration into the sewage tank to dilute wastewater concentration.

4. Permanent Multi-Medium Industrial Anti-Corrosion

   FRP composite material never rust or decay, resist acid, alkali, hydrogen sulfide odor and sewage medium corrosion, far longer service life than carbon steel, stainless steel and plastic cover plates.

5. Custom Precision Cutting One-Stop Processing

   Professional cutting workshop processes curved cover plates to exact tank span dimensions before delivery, perfectly fit sewage troughs of various widths without splicing gaps and odor leakage.

6. Excellent Full-Seal Odor Isolation Function

   Matching arc lap edge design forms tight sealing after installation, lock harmful waste gas inside the tank, meet environmental protection waste gas collection and emission control standards for industrial factories.

7. Lightweight Easy Transportation & Fast On-Site Installation

   Much lighter weight than concrete and metal covers, convenient lifting and handling, simple buckle lap installation without complex fixed supports, shorten environmental engineering construction cycle.

8. Wide Universal Industrial Environmental Compatibility

   Suitable for chemical factory sewage tank sealing, municipal wastewater treatment plant biochemical pool cover, printing and dyeing plant waste water trough cover, electroplating workshop waste liquid tank odor isolation and all industrial sewage treatment supporting construction.
