Hengshui Ruibin New Materials LLC is a professional manufacturer established in 2019, specializing in FRP/GRP composite products. Our Fiberglass Molding Grating FRP GRP Drainage Ditch Cover for Heavy Loads is engineered to withstand extreme traffic loads while maintaining excellent corrosion resistance and long service life. With a factory spanning 1,000–3,000 square meters and over 100 experienced employees, we deliver high-quality, customized drainage solutions for global markets. This product is ideal for industrial plants, highways, ports, and municipal drainage systems where strength and durability are non-negotiable.
Our heavy-duty FRP grating covers are manufactured using advanced compression molding technology, ensuring uniform density and consistent structural integrity. Unlike traditional metal covers, they never rust, require no painting, and provide excellent anti-slip performance even in wet conditions. The lightweight design (up to 70% lighter than steel) significantly reduces transportation and installation costs.
Key Features & Technical Specifications
Heavy Load Capacity: Designed for loads up to 1000 kN/m², suitable for airport runways, heavy truck paths, and container yards.
Corrosion & Chemical Resistance: Impervious to saltwater, acids, alkalis, and most industrial chemicals – ideal for wastewater treatment plants and chemical factories.
Anti-Slip Surface: Molded diamond or concave pattern provides superior slip resistance, meeting international safety standards.
UV & Weather Resistance: UV-stabilized resin ensures long-term outdoor performance without fading or cracking.
Fire Retardant: Optional fire-resistant grade available upon request (meets UL 94 V-0).
Lightweight & Easy Installation: Weight typically 30-40% of steel grating, reducing labor and equipment costs.
Non-Conductive & Non-Magnetic: Safe for electrical environments (e.g., substations, railways).
Low Maintenance: No need for painting, coating, or cathodic protection – zero maintenance over lifespan.

Frequently Asked Questions
Q1: What is the maximum load capacity of your FRP drainage ditch cover?
A1: Our standard heavy-duty covers can handle up to 1000 kN/m². For extra-heavy loads, we can customize the thickness and resin content to meet your requirements.
Q2: Can this product be used in corrosive environments such as chemical plants?
A2: Yes. FRP is inherently resistant to most chemicals, acids, and alkalis. We can also supply vinyl ester resin for higher chemical resistance if needed.
Q3: Do you offer custom sizes and colors?
A3: Absolutely. We can produce any size up to 2000×6000 mm and any RAL color. Minimum order quantity may apply for custom colors.
Q4: How does the price compare to steel or concrete covers?
A4: While the initial price may be slightly higher than steel, the total cost of ownership is lower due to zero maintenance, no rust, and longer lifespan. Concrete covers are heavier and more expensive to install.
Q5: Is the surface slippery when wet?
A5: No. Our molded grating has an integrated anti-slip texture (diamond or concave pattern) that provides excellent grip even in wet or oily conditions.
Q6: What certifications do you have?
A6: We are ISO9001:2015 and ISO9000 certified. Our products also meet international standards such as ASTM D3841 for grating. Additional certifications like UL or CE can be arranged upon request.
Q7: What is the lead time for a standard order?
A7: For standard sizes, lead time is 15–20 working days. Custom orders may require 25–30 working days depending on complexity.
Q8: Do you provide samples before bulk order?
A8: Yes, we offer free samples (shipping cost may apply) for you to evaluate the quality and performance. Please contact our sales team.
