Hengshui Ruibin New Materials LLC, established in 2019 and located in Hengshui, Hebei, China, is a professional manufacturer specializing in FRP/GRP composite products. With a factory spanning 1,000–3,000 square meters and a dedicated team of 101–200 employees, we have been delivering high-quality fiberglass solutions to global markets. Our FRP/GRP Plastic Grating with Gritted or Concave Surface is designed to provide superior slip resistance, durability, and corrosion resistance for demanding industrial environments. Each panel is manufactured under strict quality control systems certified by ISO9001 and ISO9000, ensuring consistent performance and long service life.
This fiberglass grating is engineered from a composite of glass fiber and thermosetting resin, offering a lightweight yet robust alternative to traditional steel or wood gratings. The gritted surface option provides exceptional anti-slip properties, while the concave surface variant offers self-cleaning and drainage advantages. Whether used in chemical plants, water treatment facilities, offshore platforms, or pedestrian walkways, our grating withstands harsh chemicals, UV exposure, and heavy loads without rusting or rotting.
Key Features & Technical Specifications
Material Composition: High-quality E-glass fiber with polyester or vinyl ester resin, ensuring excellent mechanical strength and chemical resistance.
Surface Options: Gritted (silica sand embedded) for maximum slip resistance; Concave (grooved) for efficient liquid drainage and self-cleaning.
Load Capacity: Available in light, medium, and heavy duty grades to suit different load requirements, from pedestrian traffic to heavy machinery.
Corrosion Resistance: Non-corrosive, non-conductive, and resistant to a wide range of acids, alkalis, and solvents, making it ideal for harsh industrial environments.
Lightweight & Easy Installation: 70% lighter than steel grating, reducing structural load and installation labor costs. Can be cut and drilled on-site with standard tools.
Color Options: Standard colors include yellow, gray, and green; custom colors available upon request for safety coding or aesthetic integration.
Panel Dimensions: Standard size up to 1220mm x 3660mm, with custom sizes and shapes available to meet specific project requirements.
Certifications: Manufactured under ISO9001:2015 and ISO9000 certified quality management systems.

Benefits to Your Business
Lower Maintenance Costs: Unlike steel grating, FRP/GRP does not rust, rot, or require painting. Minimal upkeep saves you time and money over the product's lifespan.
Enhanced Safety: The gritted surface provides a high coefficient of friction even when wet, reducing slip-and-fall accidents in industrial environments.
Versatile Application: Suitable for walkways, platforms, trench covers, stair treads, and marine structures. Available in various mesh sizes and thicknesses to match your specific load and span requirements.
Eco-Friendly: Our composite materials are inert and do not leach chemicals into the environment. The long service life reduces waste generation.
Customizable: We offer custom panel sizes, shapes, colors, and resin systems (e.g., fire-retardant, UV-stabilized) to meet unique project specifications.

Frequently Asked Questions
Q: What is the difference between gritted and concave surface grating?
A: The gritted surface has a layer of silica sand embedded into the top, providing maximum slip resistance for wet or oily environments. The concave surface features a series of grooves that allow liquids to drain away quickly, reducing the risk of slipping while also offering a self-cleaning effect.Q: Can this grating be used outdoors in direct sunlight?
A: Yes, our standard polyester resin formulation includes UV stabilizers, and we can also supply vinyl ester resin for enhanced UV resistance if required. The material does not degrade or become brittle under prolonged sun exposure.Q: What load capacity does the grating support?
A: Load capacity depends on the thickness, mesh size, and resin type. We offer light-duty (pedestrian), medium-duty (light vehicle), and heavy-duty (industrial machinery) options. Please provide your span and load requirements, and we can recommend the appropriate grade.Q: Is the grating fire-resistant?
A: Our standard product meets Class 1 flame spread rating (ASTM E84). For applications requiring higher fire resistance, we can supply a fire-retardant resin system. Please specify your fire code requirements.Q: Can I cut the grating on-site to fit my dimensions?
A: Yes, FRP grating can be cut, drilled, and shaped easily using standard tools such as diamond saw blades or carbide-tipped blades. No special equipment is needed.Q: What colors are available, and can I get custom colors?
A: Standard colors include yellow, gray, and green. Custom colors (e.g., safety orange, blue) are available upon request with a minimum order quantity. We can also add color coding for different zones in your facility.Q: How long does the grating last?
A: Under normal industrial conditions, our FRP grating has a service life of 10–20 years, depending on the environment and load. It does not rust, rot, or require painting, which significantly reduces lifecycle costs.Q: What is the minimum order quantity?
A: For standard sizes and colors, the MOQ is 50 square meters. For custom specifications, please contact us for a quotation. We offer flexible quantities to suit both small and large projects.
