Product Overview

Huangang molded FRP U-shaped drainage channel is integral composite drainage trough specially designed for surface water collection and discharge, produced in Henan, China via integral molding craft with glass fiber reinforced resin high polymer composite as raw material. The standard U-groove structure matches various detachable grate covers to filter debris while accelerating water flow, effectively solving accumulated water problems in warehouse, greenhouse and aquaculture sites. The product surface is smooth to reduce water flow resistance, length and overall color can be fully customized to fit site layout and aesthetic demands, with precision cutting service for on-site dimensional matching. It supports three flexible installation methods: underground buried embedment, ground surface laying and side wall vertical mounting to adapt different drainage construction plans. Inherent composite material features outstanding long-term anti-corrosion and anti-aging capability, resisting seawater, aquaculture sewage, agricultural chemical liquid and soil acid-base erosion without cracking or fading under long-term outdoor exposure. Besides lightweight easy transportation and installation, the material owns non-conductive insulation property to avoid hidden electric leakage hazards near power lines, making it a durable low-maintenance drainage liner for agricultural, industrial and aquaculture facilities.

Core Product Advantages

1. Integral Molded U Channel & Multi-Style Grate Matching

   One-piece molding eliminates leakage gaps; diversified grate covers separate solid waste and speed up drainage, select light or heavy load lids for pedestrian and vehicle passage scenarios.

2. Superior Anti-Corrosion & Long-Term Anti-Aging Performance

   FRP composite raw material withstands aquaculture brine, agricultural fertilizer liquid and outdoor UV radiation, no rust, rot or aging after years of outdoor use, far longer service life than metal and concrete drains.

3. Lightweight High Strength Easy Construction

   Much lighter weight than concrete drainage gutters, reduce hoisting and laying labor cost; thickened rib reinforcement ensures high compression resistance without collapse under heavy rolling.

4. Flexible Multi-Mode Installation & Full Customization

   Underground, ground and side three installation ways adapt flat ground, slope wall and greenhouse elevated bed layouts; arbitrary length cutting and color customization match all project specifications.

5. Safe Non-Conductive Insulation Characteristic

   Fully insulated composite material avoids electric conduction risk when drainage trough runs near cables, safe for warehouse, farm and power adjacent drainage areas.

6. Smooth Inner Surface Fast Water Discharge

   Smooth seamless inner wall reduces water friction resistance, prevent sludge adhesion and blockage, easy daily flushing and cleaning with low maintenance workload.

7. Low Whole-Life Operation Cost

   No regular anti-rust coating, anti-corrosion treatment or crack repair required after installation, one-time construction for decades of stable drainage operation.

8. Multi-Industry Universal Drainage Application

   Suitable for factory warehouse rainwater drainage, vegetable/flower greenhouse irrigation drainage, fish/shrimp aquaculture sewage discharge, livestock farm cleaning wastewater collection and landscape garden surface drainage.

Wide Application Scope

This FRP fiberglass U drainage channel with grate cover serves as anti-corrosion drainage liner for the following industrial, agricultural and aquaculture projects:

1. Industrial storage facilities: Logistics warehouse, factory workshop floor rainwater and cleaning wastewater drainage system

2. Agricultural greenhouse planting: Vegetable, fruit and flower greenhouse irrigation surplus water and rainwater collection trough

3. Aquaculture breeding farms: Fish, shrimp and crab pond sewage discharge channel, circulating water filtration drainage liner

4. Livestock breeding plants: Pig, cattle and poultry farm cleaning sewage collection and discharge gutter

5. Landscape & commercial yards: Park garden pedestrian path drainage, farm market surface water collection channel
