As a professional manufacturer based in Hengshui, Hebei, China, Hengshui Ruibin New Materials LLC (established 2019) specializes in producing high-quality drainage solutions. Our Polymachine Trench Drain Cover with a self-cleaning design is engineered to deliver exceptional performance in demanding environments. With a width of 200mm, an open area of 80%, and a lamella spacing of 5mm, this cover offers superior water flow while minimizing debris accumulation. Designed for durability and low maintenance, it represents a reliable choice for architects, contractors, and facility managers worldwide.
Our factory spans 1,000–3,000 square meters and is staffed by 101–200 experienced employees, allowing us to maintain strict quality control and efficient production. We export to diverse markets including North America, South America, Europe, Southeast Asia, Africa, and Oceania, with annual export values reaching US$2.5–5 million. Every Polymachine cover is manufactured using advanced composite materials that resist corrosion, UV degradation, and heavy loads, ensuring long service life even under harsh conditions.
Product Features & Benefits
- Self-Cleaning Design – The specially angled lamella and smooth surface allow water and debris to flow through continuously, preventing clogging and reducing manual cleaning frequency. This feature is especially valuable in areas with heavy rainfall, leaves, or sediment.
- High Open Area (80%) – Compared to standard drain covers (typically 50-70% open area), our 80% open area maximizes hydraulic capacity, making it ideal for drainage of parking lots, roads, sidewalks, and industrial sites.
- Optimal Lamella Spacing (5mm) – Strikes a perfect balance between water intake and safety. The 5mm spacing prevents large objects (e.g., stones, cans) from entering the drain while still allowing rapid water passage.
- 200mm Width – A versatile size compatible with most standard trench channels. It can be used in new installations or retrofitted into existing systems.
- Durable Polymer Composite – Made from high-strength polymer concrete reinforced with fibers, the cover offers excellent impact resistance, freeze-thaw stability, and chemical resistance. It does not rust like steel or crack like brittle concrete.
- Load Class Options – Available in different load ratings (e.g., A15 for pedestrian areas, B125 for light vehicles, C250 for heavy traffic) to suit various applications. Custom load classes can be produced upon request.
- Anti-Slip Surface (Optional) – A textured top surface provides additional traction for pedestrian safety, even in wet conditions. This can be ordered as an option.
- Easy Installation – Lightweight design (typically 30-40% lighter than equivalent steel covers) simplifies handling and reduces labor costs. The cover fits securely into standard channels without special tools.
- Low Maintenance – The self-cleaning property, combined with non-porous material that resists staining and bacterial growth, minimizes long-term upkeep expenses.

Frequently Asked Questions
1. Can this trench drain cover withstand vehicle traffic?
Yes, it is available in load classes ranging from A15 (pedestrian) to D400 (heavy vehicles). Please specify your required load rating when ordering so we can produce the appropriate version.
2. How does the self-cleaning design work?
The lamella are angled and shaped to create a Venturi effect – flowing water accelerates and carries debris through the openings. The smooth non-stick surface prevents leaves, dirt, and sand from adhering, so rain or hose water naturally flushes the cover clean.
3. Is the material resistant to salt and chemicals?
Yes, the polymer composite is inherently resistant to de-icing salts, oil, gasoline, and most common chemicals. This makes it suitable for coastal areas, parking garages, and industrial facilities.
4. What is the typical installation procedure?
Our covers are designed to sit securely in standard trench channels (compatible with most brands). Simply place the cover into the channel frame or resting ledge. No special tools or locking mechanisms are required for normal use; optional locking screws can be added for security.
5. Can I get a different width or lamella spacing?
Absolutely. We offer customized widths from 100mm to 300mm and lamella spacing from 3mm to 10mm. Minimum order quantities may apply for non-standard sizes. Contact our sales team with your requirements.
6. Will the 80% open area allow small animals to enter?
The 5mm spacing is designed to prevent rodents and other small animals from entering the drain. The self-cleaning feature also reduces organic matter that could attract pests.
7. What is the warranty period?
We provide a standard 2-year warranty against manufacturing defects. Extended warranty options are available upon request. Please review our terms for specific conditions.
8. Do you offer samples before bulk order?
Yes, we provide samples at cost (refundable upon bulk purchase). Shipping is typically via express courier. Contact us to arrange sample delivery.
