Welcome to Hengshui Ruibin New Materials LLC – your trusted manufacturer of high-performance FRP/GRP composite solutions. Since 2019, we have specialized in producing fiber-reinforced polymer water channels and drainage gratings designed for demanding industrial environments. Our products combine exceptional strength, corrosion resistance, and lightweight construction to deliver long-lasting drainage performance. With a factory spanning 1,000–3,000 square meters and a dedicated team of 101–200 employees, we ensure every grating meets rigorous quality standards.
Our FRP/GRP Fiber Resin Composite Water Channel and Drainage Grating is engineered to withstand heavy loads, chemical exposure, and harsh weather conditions. Whether you need a reliable solution for wastewater treatment plants, chemical factories, or food processing facilities, our gratings offer superior durability and safety. The anti-slip surface and customizable dimensions make them ideal for both new installations and retrofit projects.
Key Features and Benefits
Corrosion Resistance: The fiberglass composite resists acids, alkalis, salts, and other corrosive substances – perfect for chemical plants and marine environments.
High Strength-to-Weight Ratio: Up to 75% lighter than steel gratings, reducing installation costs and structural load.
Slip Resistance: Embedded silica grit provides excellent traction even when wet, ensuring worker safety.
Low Maintenance: Non-conductive, non-magnetic, and UV-stable – no painting or rust-proofing required.
Customizable Design: Available in various sizes, colors, and load ratings to match your specific application.
Easy Installation: Can be cut, drilled, and assembled on-site with standard tools.

Frequently Asked Questions
Q1: What is the difference between FRP and GRP?
A: FRP (Fiber Reinforced Polymer) and GRP (Glass Reinforced Plastic) are essentially the same material – fiberglass reinforced plastic. Both terms are used interchangeably in the industry. Our products are made from high-quality glass fiber and thermosetting resin.
Q2: Can these gratings be used in food processing areas?
A: Yes. Our standard resin is food-grade compatible and meets FDA requirements for indirect contact. We also offer a special resin formulation for applications requiring high hygiene standards. Please specify your needs when ordering.
Q3: How do I choose the correct load class for my project?
A: Load class depends on the expected traffic. For pedestrian areas, C250 (250 kN) is sufficient. For light vehicles, D400 (400 kN) is recommended. For heavy trucks or forklifts, E600 (600 kN) or higher is required. Our technical team can help you select the right class based on your site conditions.
Q4: Are the gratings resistant to UV radiation?
A: Yes, the resin includes UV stabilizers to prevent degradation from sunlight. However, for prolonged outdoor exposure, we recommend adding a UV protective gel coat for extended service life.
Q5: What is the typical lead time for custom orders?
A: For standard sizes, lead time is 7–15 days. Custom dimensions, colors, or special resin may require 15–25 days. We work closely with our logistics partners to ensure timely delivery via Tianjin or Qingdao port.
Q6: Do you provide installation instructions?
A: Absolutely. We provide detailed installation manuals and technical drawings for each order. Our support team is also available for remote guidance.
Q7: What is the warranty period?
A: We offer a standard 2-year warranty against manufacturing defects. Extended warranties are available upon request for critical projects.
Q8: Can I get a sample before placing a bulk order?
A: Yes, we provide free samples (customer pays shipping) for evaluation. Contact our sales team to request a sample of your preferred specification.
