Hengshui Ruibin New Materials LLC, located in the industrial hub of Hengshui, Hebei, China, is proud to introduce our Fiberglass Trench Cover Resin Composite Grating for Drainage Systems. Designed to meet the rigorous demands of modern infrastructure, this product combines exceptional strength with lightweight convenience, offering a reliable solution for drainage, trench covering, and industrial flooring. Engineered using premium fiberglass reinforced plastic (FRP) and advanced resin composite technology, our grating provides superior corrosion resistance, slip resistance, and long service life, making it an ideal choice for municipal projects, chemical plants, and commercial facilities.
Our grating is manufactured through a pultrusion process that ensures uniform fiber distribution and consistent mechanical properties. The result is a product that withstands heavy loads, extreme weather, and chemical exposure without warping or deteriorating. Whether you need a standard size or a custom configuration, we offer flexible solutions that fit your specific drainage system requirements. Below, we dive into the key features, technical specifications, and benefits that set our product apart.
Key Features & Benefits
Exceptional Corrosion Resistance: Unlike steel gratings, our FRP composite does not rust or corrode, even in harsh chemical, saline, or acidic environments. This extends the lifespan of your drainage system significantly.
Lightweight Yet Strong: With a weight approximately 75% less than steel, installation is faster and requires less labor. Despite its lightness, it offers high load-bearing capacity suitable for pedestrian and light vehicular traffic.
Anti-Slip Surface: The textured surface provides excellent grip even when wet, reducing the risk of slips and falls in industrial or public areas.
UV & Weather Resistance: The resin matrix is formulated to resist ultraviolet degradation, ensuring the grating maintains its color and structural integrity under prolonged sun exposure.
Non-Conductive & Non-Magnetic: Ideal for use in electrical substations, data centers, or areas where spark hazards exist, as FRP does not conduct electricity.
Low Maintenance: No need for painting, coating, or regular anti-corrosion treatments. A simple wash with water keeps it clean.
Customizable Dimensions: Available in various panel sizes, thicknesses, and grid configurations to match trench dimensions and load requirements.
Easy Cutting & Modification: Can be cut on-site using standard tools, allowing for quick adaptation to irregular shapes or pipe penetrations.

Why Choose Our Fiberglass Trench Cover?
Our resin composite grating is specifically designed for drainage systems, offering a combination of durability and ease of use that traditional materials cannot match. The pultrusion process ensures consistent quality, and each panel is inspected for dimensional accuracy and surface finish. Benefits for your project include:
Reduced installation time due to lightweight panels — no heavy lifting equipment required.
Long-term cost savings from zero maintenance and corrosion resistance.
Enhanced safety for workers and pedestrians with anti-slip surface.
Environmental friendly: FRP is inert and can be recycled at end of life.
Customizable to fit complex trench geometries, including curved or angled sections.
We also offer a range of complementary accessories such as locking clips, fasteners, and support frames to ensure a secure and stable installation. Our engineering team can assist in load calculations and provide recommendations based on your specific project requirements.

Frequently Asked Questions (FAQ)
Q: What is the typical load capacity of your FRP trench cover?
A: Our standard grating can handle loads up to 50 kN/m², equivalent to pedestrian and light vehicular traffic. For heavy-duty applications, we can customize the thickness, fiber content, and resin type to meet specific load requirements. Please provide your load class for a tailored solution.Q: Can the grating be cut to size on site?
A: Yes, our FRP grating can be easily cut with standard carbide-tipped saw blades, angle grinders, or jigsaws. This allows for on-site adjustments to fit irregular trench shapes or accommodate pipes. We recommend using proper PPE and following our cutting guidelines.Q: How does the corrosion resistance compare to stainless steel or galvanized steel?
A: Our resin composite grating offers superior resistance to a wide range of chemicals, including acids, alkalis, and salts. Unlike stainless steel, it will not pit or corrode in chloride environments, and unlike galvanized steel, it does not require a protective coating that can wear off. This makes it ideal for wastewater treatment plants, chemical processing, and marine applications.Q: Is the surface slippery when wet?
A: The surface is designed with an embedded anti-slip grit that provides excellent traction even in wet or oily conditions. The coefficient of friction is significantly higher than smooth metal or plastic gratings, meeting safety standards for walkways and platforms.Q: What colors are available?
A: Standard colors are gray, yellow, and green. We can match custom colors (e.g., safety orange, blue) for large orders. The color is integrated into the resin, so it will not peel or fade easily.Q: Can your product be used in fire-sensitive areas?
A: Yes, we can manufacture fire-retardant grades with a Class B1 rating (European standard) upon request. These incorporate special additives in the resin to reduce flame spread and smoke generation. Please specify your fire safety requirements when ordering.Q: What is the typical lead time for orders?
A: For standard sizes and quantities, lead time is around 15–20 working days after confirmation of order. Custom sizes or specialized resin types may require 25–30 working days. We also offer express production for urgent projects (adds a surcharge).Q: Do you provide installation instructions or technical support?
A: Absolutely. We provide detailed installation manuals, including recommended fastening methods, spacing of supports, and handling guidelines. Our technical team is available via email or video call to assist with any questions during installation.
