Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019, proudly presents our FRP Drain Trough with 0.5% Pre-Configured Slope and Rubber Gasket Seal. Designed specifically for underground parking lot drainage, these troughs combine superior corrosion resistance with precise hydraulic performance. Our factory spans 1,000-3,000 square meters and employs 101-200 skilled workers, ensuring rigorous quality control. With annual export value reaching US$2.5-5 million and shipments to major global markets including North America, Europe, and Oceania, our FRP drainage solutions are trusted by contractors worldwide.
Key Features & Benefits
- 0.5% Pre-Configured Slope – Factory-integrated gradient ensures optimal water flow velocity, preventing standing water and sediment buildup without on-site adjustment.
- Rubber Gasket Seal – High-quality EPDM rubber gasket pre-installed at joints guarantees watertight connections, eliminating leakage even under continuous water pressure.
- FRP Construction – Fiberglass reinforced plastic offers exceptional strength-to-weight ratio, resisting corrosion from road salts, chemicals, and UV exposure. It also provides electrical insulation and low thermal conductivity.
- Easy Installation – Lightweight modules (approx. 20-30 kg per meter) can be handled manually; interlocking design with gasket simplifies alignment and reduces labor costs.
- 5-Year Warranty – Backed by our commitment to durability; covers manufacturing defects and material failures under normal use conditions.
- Customizable Dimensions – Available in lengths from 1m to 3m, widths from 100mm to 200mm (or custom), with color options to match surrounding pavements.
- Load Capacity Options – Optional load classes A15 (pedestrian/light traffic) or B125 (car parking areas) per EN 1433 standard.

Our FRP drain troughs are extensively tested for hydraulic efficiency, structural integrity, and seal performance. The 0.5% slope aligns with industry best practices for self-cleaning channels, minimizing maintenance frequency. The rubber gasket seal withstands hydrostatic pressure up to 0.5 bar, ensuring zero leakage in continuous flow scenarios.

Frequently Asked Questions
-
Q: Can this drain trough handle heavy vehicle loads in parking garages?
A: Yes, we offer load class B125 which is suitable for parking lot traffic including passenger cars and occasional light trucks. For heavier loads, please inquire about custom reinforcement. -
Q: Is the rubber gasket replaceable?
A: The gasket is factory-installed and designed for the product's lifespan. However, if replacement is needed, we can supply matching gaskets as spare parts upon request. -
Q: What is the recommended installation procedure for underground parking?
A: Install on a compacted gravel base with concrete encasement minimum 100mm on each side. Ensure continuous slope (0.5%) along the entire run. Use our joint alignment clips for precise gasket compression. Detailed manual is included. -
Q: How does the 0.5% slope affect drainage performance?
A: The 0.5% gradient provides self-cleaning velocity (approx. 0.9 m/s at design flow) for most parking lot runoff, preventing sediment deposition and clogging. -
Q: Are there color options to match the concrete floor?
A: Yes, standard colors are gray and black. Custom colors (e.g., concrete gray, dark brown) can be produced for minimum order quantities. Please contact our sales team. -
Q: What certifications does this product have?
A: Our products are manufactured following ISO 9001 quality management principles (factory registered) and tested per EN 1433 for load and hydraulic performance. Specific certifications can be provided upon request. -
Q: How long is the delivery time for a typical order?
A: For standard sizes, lead time is approximately 15-20 working days after order confirmation. Custom sizes may require 25-30 working days depending on quantity. -
Q: Can I get free samples before placing a bulk order?
A: Yes, sample orders are available. Please contact us to discuss sample costs and shipping arrangements.
