Product Introduction

FAQ

FRP U-shaped drainage channel, also known as U trench or SMC molded linear drain, is integrally compression-molded with SMC sheet molding compound (fiberglass reinforced plastic). It features a curved U-shaped inner cavity and matching FRP trench covers. Widely used for linear drainage in municipal, industrial and landscape projects.

1. Raw Material

FRP (Fiberglass Reinforced Plastic), composite of unsaturated polyester resin and glass fiber, one-piece molded without gaps.

2. Complete Product Specifications

(1) Standard Single Section Length: 1000mm per piece

(2) Optional Inner Width Sizes: 100mm / 150mm / 200mm / 300mm

(3) Customizable Depth: Custom depth available as project demands

(4) Load-Bearing Classification

Light-duty: Pedestrian paths, residential gardens, foot traffic only

Medium-duty: Community trolleys, electric bikes, light hand carts

Heavy-duty: Factory forklifts, trucks, fire emergency lanes

(5) Matching Cover Colors: White, Green, Custom color customization supported

(6) Supporting Accessories: End caps, tee connectors, cross connectors, inspection ports, leveling adjustment pads

3. Main Structure

(1) U-shaped Channel Body

Curved inner surface for smooth water flow without sediment accumulation. External reinforced ribs enhance compression resistance. Buckle joints on side walls allow unlimited extension by connecting multiple sections.

(2) Matching Trench Cover

Molded from the same FRP material with anti-slip long drain holes. Different load grades to match various usage scenarios.

(3) Auxiliary Fittings: End caps, tee/cross connectors, inspection ports, leveling pads.

Core Product Advantages:

1. Superior corrosion resistance & long service life

Resistant to acid, alkali, sewage and chemical wastewater. No rust or erosion. Ideal for chemical plants and wastewater treatment plants, service life over 30 years outdoors.

2. Light weight & easy installation

Only 1/5 the weight of concrete drains. Single-person handling without heavy lifting equipment, cutting construction time by 60%.

3. Smooth inner wall for high drainage efficiency

Low friction U-curve cavity prevents sludge clogging, eliminates standing water on ground with continuous linear drainage.

4. High compressive & crack resistance

Integral SMC molding delivers strong toughness, anti-settlement and anti-crushing performance. Heavy-duty versions support factory trucks and fire engines.

5. Zero water leakage

Seamless monolithic structure plus sealing strips at joints, avoiding crack leakage issues of concrete channels.

6. Maintenance-free & low long-term cost

No moss growth, no corrosion or rust repair. Integrated color will not peel off, no regular repainting required.

7. Customizable sizes & colors

Multiple inner width options. Customizable length, depth, load-bearing grades and surface colors.

Application Scenarios:

1. Industrial zones: Chemical factories, electroplating workshops, food plants, sewage treatment stations, logistics warehouses

2. Municipal works: Sidewalks, green belts, parking lots, non-motor vehicle lanes

3. Landscape projects: Parks, scenic spots, residential walkways, swimming pool perimeter rainwater collection

4. Livestock farming: Manure and washing wastewater drainage

5. Commercial buildings: Mall plazas, underground garage rainwater diversion

6. Anti-corrosion special sites: Acid pickling workshops, chemical wastewater collection ditches
