At Hengshui Ruibin New Materials LLC, we are a professional manufacturer dedicated to producing high-performance fiberglass composite materials. Our Heavy-Duty Fiberglass Grating with a 38mm opening and 6mm bar width is engineered for use as industrial trench covers and heavy-load platforms. This product combines high load capacity, strong corrosion resistance and a lightweight structure, making it suitable for chemical plants, refineries, food processing facilities, water treatment stations and public infrastructure projects. Since our establishment in 2019, we have focused on delivering durable composite solutions for demanding environments.
Our grating is produced with continuous glass fiber rovings and premium resin systems, giving it excellent structural rigidity and impact resistance. The 38mm square opening supports heavy loads while allowing water and debris to pass through, preventing ponding on trench covers and industrial walkways. The 6mm bar width is optimized to create a smooth walking surface without sacrificing open area or load strength. This balance makes the grating particularly suitable for drainage covers, pit covers, walkways and support platforms in both industrial and commercial settings.
Each panel is manufactured to exacting dimensions using advanced molding technology. Surface options include a high-friction grit coating that is bonded into the resin to prevent slipping even in wet, oily or snowy conditions. The mesh pattern reduces trip hazards and provides comfortable footing for workers. In addition, the selected resin system offers fire-retardant properties that enhance safety in workplaces where sparks or flames are present.

Core Advantages
- High structural strength: The grating withstands heavy vehicle and equipment loads without permanent deformation, making it reliable for industrial trench covers and flooring.
- Corrosion resistance: It resists acids, alkalis, salts and moisture, making it suitable for chemical plants, plating lines and coastal environments.
- Anti-slip security: The grit-coated surface provides good traction in different weather conditions, reducing slip-and-fall accidents.
- Lightweight and labor-saving: FRP grating weighs much less than steel, ensuring easier handling, faster installation and lower transportation cost.
- Electrical and thermal insulation: It is non-conductive and has low thermal conductivity, adding safety in electrical substations and hot process areas.
- Low maintenance: No rusting or painting is required; the pigments are blended into the resin, so the color stays fresh for years.
- Design flexibility: Panel dimensions, openings, colors and resin formulations can be customized to meet project specifications.
Load Performance and Safety
This heavy-duty fiberglass grating is manufactured with a high-glass-content formulation that provides an excellent stiffness-to-weight ratio. It withstands high point loads and distributed loads, making it a safe, long-term alternative to steel grating in industrial trench covers. The 38mm mesh opening minimizes the risk of wheel or heel entrapment, while the 6mm bar width delivers a larger bearing surface to support loads more uniformly. For extra safety, the grit coating is fused onto the top surface and remains effective throughout the service life because it is embedded in the resin rather than painted on.
Designed for Industrial Trench Covers
This grating is particularly effective for trench covers and pit covers in industrial workshops, warehouse aisles, municipal roads and pedestrian areas. The 38mm opening allows water to drain quickly while preventing small tools or debris from falling through. In industrial roadways, these panels can be installed in a supporting steel frame, creating a flush surface that withstands forklift traffic and heavy loads. Our engineers can help you determine the correct thickness and panel layout based on the expected load and support span.
Customization and Manufacturing Capability
At our factory in Hengshui, Hebei, we have a well-equipped production line and an experienced team of 101-200 employees. We can produce grating panels in various sizes to fit your trench covers with minimal waste. We also support secondary fabrication processes such as cutting, drilling, routing and sanding. Custom prototypes can be developed based on your drawings. With an annual export value of US$2.5 million to US$5 million, we have built trusted partnerships with buyers across North America, South America, Europe, Southeast Asia, Africa, the Middle East, Oceania and many other regions.
Reliable Export and After-Sales Support
Since our founding in 2019, Hengshui Ruibin New Materials LLC has grown into a reliable manufacturer with a 1,000-3,000 square meter production facility. Our products are shipped from both Port of Tianjin and Port of Qingdao, offering flexible incoterms and efficient logistics. Every batch undergoes strict in-house inspection for dimension accuracy, surface quality and load performance. We are committed to supplying durable, cost-effective and custom-engineered trench cover solutions. Contact our team with your project requirements, and we will provide a competitive quotation and professional technical guidance.
Frequently Asked Questions
Q1: What sizes are available? We offer standard panels as well as custom dimensions. Please provide the width, length and thickness required, and we will manufacture accordingly.
Q2: Can this grating handle heavy vehicles? Yes, this heavy-duty type is designed for industrial trench covers. The load capacity depends on thickness, panel support span and resin type. Our engineers can help you choose the right specification for your expected traffic load.
Q3: Is the grating slippery when wet? No. The standard anti-slip grit surface provides good friction even in wet or oily conditions. Other anti-slip textures are also available upon request.
Q4: Can we get specific colors? Yes. Common colors include yellow, grey, green and black, and custom RAL colors can be matched for large orders.
Q5: What about chemical resistance? The grating is made of fiberglass reinforced plastic, which resists most industrial chemicals. For highly corrosive applications, we can supply a vinyl ester resin system to improve performance further.
Q6: Do you provide cutouts or fabricated parts? Yes, we can perform cutting, drilling, notching and beveling according to your drawings. This helps save installation time on site.
Q7: How do you pack the grating for sea transport? We pack panels in wooden crates or pallets with protective foam, ensuring they arrive without damage. Shipment is arranged from Tianjin or Qingdao.
Q8: What is the minimum order quantity? The MOQ depends on product specification and customization level. For standard colors and sizes, we can be flexible; please consult our sales team.
