Product Overview

Huangang FRP fiberglass arched hood is arch curved composite sealing cover customized for environmental protection wastewater treatment equipment, produced in Henan, China adopting standard multi-layer hand lay-up fiberglass laminating molding technology. Cross layered hand laid fiber structure greatly enhances the bending compressive strength of the arched cover, capable of bearing pedestrian walking and light temporary stacking without deformation or cracking. The outer surface adopts seamless smooth gel coat treatment, compact and non-porous structure prevents sludge, industrial waste gas and sewage scale from adhering, easy to flush and maintain daily. The natural arched streamline design realizes automatic rainwater diversion, no water accumulation on the cover surface, effectively avoiding rainwater permeation into the tank and affecting wastewater treatment concentration. Our factory supports precision cutting processing according to engineering drawing dimensions, cutting the arched hood into matching width and length for on-site installation without secondary modification. The integral fiberglass resin composite formula has permanent anti-corrosion performance, long-term resistant to industrial acid-base wastewater, hydrogen sulfide corrosive gas and coastal salt fog erosion, completely solving the rust, decay and leakage problems of metal and concrete cover plates. It is widely matched with environmental protection equipment such as sewage biochemical pools, sedimentation tanks, waste liquid storage troughs, waste gas collection pipelines of chemical plants, printing and dyeing factories, electroplating workshops and municipal sewage treatment stations.

Core Product Advantages

1. Multi-Layer Hand Lay-Up Reinforced Arch Structure

   Cross laminated fiberglass hand lay-up craft ensures uniform internal fiber distribution, balanced arch bending bearing capacity, safe for daily inspection walking without breakage under long-term outdoor load.

2. Smooth Stain-Proof Gel Coat Outer Surface

   Seamless smooth gel coat prevents sludge, chemical scale and corrosive waste gas residue adhesion, simple water flushing to restore clean state, reduce daily equipment maintenance labor cost.

3. Arch Streamline Self-Draining Rainwater Design

   Natural arch radian realizes automatic rainwater outflow, no ponding on cover surface, stop rainwater infiltration into sewage tank to dilute treatment medium concentration.

4. Permanent Multi-Medium Industrial Anti-Corrosion

   FRP composite material will never rust or rot, 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 One-Stop Cutting Processing

   Professional cutting workshop processes arched hoods to exact tank span sizes before delivery, perfectly fit sewage troughs of various widths without splicing gaps and harmful gas leakage.

6. Excellent Full-Seal Waste Gas Isolation Function

   Matching arch lap edge structure forms tight sealing after installation, lock toxic and odorous waste gas inside the tank, meet environmental protection waste gas collection and emission control standards for industrial enterprises.

7. Lightweight Easy Transportation & Fast On-Site Installation

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

8. Wide Universal Environmental Equipment Matching

   Perfectly supporting biochemical pools, sedimentation tanks, regulating tanks, waste liquid troughs, waste gas absorption devices of chemical plants, municipal sewage stations, printing and dyeing workshops, electroplating factories and all industrial environmental protection equipment.
