At Hengshui Ruibin New Materials LLC, we specialize in producing high-quality Pultruded Steel Reinforced Fiberglass GRP FRP Grating Profiles for structural applications. As a manufacturer with over 5 years of expertise and a dedicated team of 101-200 employees, we combine advanced pultrusion technology with stringent quality control to deliver grating profiles that offer exceptional strength, corrosion resistance, and lightweight properties. Our profiles are engineered to meet the demands of heavy-duty industrial environments, providing a reliable alternative to traditional steel grating. With an annual export value of US$2.5-5 million, we serve global markets including North America, Europe, Southeast Asia, and the Middle East, ensuring that every profile meets international standards.
Our pultruded grating profiles are manufactured using continuous fiberglass roving and thermosetting resin, reinforced with steel rods for enhanced load-bearing capacity. The pultrusion process ensures uniform cross-section, high fiber content, and excellent dimensional stability. These profiles are ideal for use in corrosive environments such as chemical plants, offshore platforms, water treatment facilities, and food processing plants where traditional metal gratings fail due to rust or chemical attack. The non-conductive and non-magnetic properties of FRP make them suitable for electrical substations and sensitive equipment areas.
Key Product Features & Technical Specifications
- High Strength-to-Weight Ratio: Our profiles are up to 70% lighter than steel while maintaining comparable strength, reducing installation costs and structural load.
- Corrosion & Chemical Resistance: Resistant to a wide range of acids, alkalis, solvents, and UV radiation, ensuring long service life in harsh environments.
- Fire Retardant Options: Available with halogen-free, fire-retardant resin formulations meeting Class 1 or ASTM E84 standards.
- Customizable Dimensions: Profile height, width, and mesh size can be tailored to your specific load requirements and span lengths.
- Slip-Resistant Surface: Gritted top surface with embedded silica sand provides excellent traction even in wet or oily conditions.
- Maintenance-Free: No need for painting, coating, or galvanizing; simple wash-down keeps the grating like new.

Frequently Asked Questions (FAQ)
- Q: What is the difference between GRP and FRP grating? A: GRP stands for Glass Reinforced Plastic and FRP for Fiber Reinforced Plastic. Both refer to the same material category; GRP is a subset of FRP using glass fibers. Our profiles are made from fiberglass reinforcement, so they are both GRP and FRP.
- Q: Can these profiles be used in outdoor environments exposed to UV? A: Yes, our standard resin includes UV inhibitors to prevent degradation. For extreme UV exposure, we recommend a vinyl ester or premium polyester resin with additional UV stabilizers.
- Q: What load capacity can your profiles support? A: Load capacity depends on profile dimensions, span, and resin type. Our standard profiles can support up to 500 kg/m² for typical walkway applications. For higher loads, we can custom design with thicker profiles or additional steel reinforcement.
- Q: Are the profiles fire resistant? A: We offer fire-retardant resin options that meet Class 1 (BS 476) or ASTM E84 standards. Please specify your fire rating requirement when ordering.
- Q: How do I install your grating profiles? A: They can be cut, drilled, and fastened using standard tools. Installation is similar to steel grating but requires less heavy equipment. We provide installation guidelines and can recommend suitable clips or fasteners.
- Q: What is the lead time for custom orders? A: For standard profiles, lead time is 15-20 days after order confirmation. Custom colors, sizes, or special resin may require 25-35 days. We work closely with you to meet your project schedule.
- Q: Do you offer samples for testing? A: Yes, we provide free samples for small sizes (up to 300x300mm). You only pay for shipping. Contact us to request a sample kit.
- Q: How do I maintain the grating? A: Simply wash with water or mild detergent. No painting or coating is needed. For heavy contamination, use a pressure washer. Avoid abrasive cleaners that may damage the surface.
