FRP SMC linear drainage ditch is prefabricated modular U-shaped drainage system integrally compression-molded from SMC sheet molding compound under high temperature and pressure. It consists of ditch bodies and matching covers. Lightweight for easy on-site transportation and installation, the product is corrosion-resistant and rust-free to meet rainwater and sewage discharge demands for various outdoor and industrial sites. Featuring modular joints for sectional assembly according to site length, it is widely adopted in municipal, commercial, industrial, cultural and landscape drainage projects.
Base Material
FRP SMC composite material; integrally molded U-shaped ditch body with matching SMC covers of the same material. Covers are available with slotted wave openings, round holes and other patterns, and some are equipped with anti-slip textures.
Structural Features
U-shaped smooth inner cavity facilitates water flow and reduces debris accumulation;
Modular joint design enables quick assembly of multiple sections;
Covers fit tightly with ditch bodies for easy disassembly and internal cleaning;
Reinforced side walls improve the overall impact resistance of the ditch.
Corrosion-resistant and rust-free: Unlike metal drainage ditches, it is immune to rust and resistant to acid, alkali, salt spray and de-icing agents, suitable for chemical plants and coastal areas.
Lightweight: Lighter than concrete and cast iron alternatives, lowering hoisting costs and reducing manual installation difficulty.
Smooth drainage: Low friction on the inner wall together with multi-pattern covers allows rapid rainwater inflow and reduces surface ponding.
Weather resistance: Tolerant to UV radiation and temperature fluctuations, maintaining stable performance outdoors without rusting.
Easy maintenance: Removable covers allow convenient clearance of sediment and fallen leaves, cutting long-term maintenance workload.
Customizable: Standard sizes available, alongside non-standard dimensions, opening patterns and OEM branding to satisfy drawing requirements of different projects.
✅ Commercial plazas, pedestrian streets, park landscapes and villa courtyards;
✅ Ground drainage around swimming pools and cultural tourism parks;
✅ Floor drainage for workshops in industrial parks;
✅ Factory roads, parking lots and municipal sidewalks;
✅ Indoor and outdoor drainage areas with anti-corrosion requirements such as food and chemical workshops.
Standard sizes are kept in stock. Bulk orders are palletized and wrapped with stretch film for protection.
Bulk shipment is supported and loading can be arranged as required by projects.
OEM and ODM customization is available; lead time for custom items depends on actual production schedules.
Specifications shall be determined based on traffic load, drainage volume and chemical conditions on site.
Ditch bodies and covers of corresponding load grades must be selected for heavy traffic areas.
For environments with high acid or alkali concentration, consult our technical team in advance for compatibility evaluation.





Q1: What are the differences between FRP drainage ditches and concrete or cast iron drainage ditches?
A: FRP‑SMC material does not rust and performs well against acid, alkali and salt spray. It is lighter and faster to install. Concrete ditches are heavy with long on-site casting cycles; cast iron ones are prone to rust and theft. Each material has its applicable scenarios. Selection can be made considering project budget and service environment.
Q2: Can it withstand vehicle traffic?
A: Products are classified by load grades. Light-duty types are for pedestrian zones. Ditch bodies and covers of corresponding heavy-load grades are required for vehicle passages. Please inform us of vehicle types for proper matching. Light-duty products are not recommended for heavy traffic roads.
Q3: Is it suitable for coastal areas, roads with acid/alkali exposure and northern roads spread with de-icing agents?
A: SMC FRP has good resistance to acid, alkali, salt spray and de-icing agents for such working conditions. For highly corrosive concentrated chemical media, share site parameters with our technical team for compatibility assessment.
Q4: Can dimensions, cover opening patterns and OEM branding be customized?
A: Non-standard sizes and cover opening patterns can be adjusted, and OEM branding service is available. Custom orders may incur mould modification costs. Lead time depends on order details. Submit drawings to our sales team for quotation.
Q5: Is installation complicated? What equipment is needed?
A: These are prefabricated units requiring no on-site casting. Manual handling and joint assembly are feasible after foundation leveling, followed by backfilling. Concrete edge reinforcement in accordance with construction codes is recommended for heavy-load applications.
Q6: What is the approximate service life?
A: The theoretical service life varies with load, buried environment and maintenance and has no fixed value. A long service cycle can be achieved for regular outdoor drainage with proper foundation construction and periodic cleaning. Severe corrosion and overload will shorten its service life.
Q7: Are samples available?
A: Samples can be provided for project evaluation. Sample and freight costs are borne by the buyer. Sample terms can be negotiated for bulk orders.
Q8: What is the lead time?
A: In-stock standard items can be shipped promptly upon order confirmation. Lead time for non-standard custom products will be confirmed according to production schedules before order placement.
Q9: How to maintain it afterwards?
A: Lift the cover to clear sediment, leaves and debris inside. Avoid prolonged heavy impact from large sharp objects on covers to prevent component damage.
Q10: Can supporting documents be provided for bidding projects?
A: Technical and commercial documents including datasheets and copies of test reports are available. Contact our sales representative to obtain them.
