Product Description
Product Introduction
Introduction to FRP Grating Products
Molded fiberglass grating is an advanced composite structural component whose exceptional performance stems from its unique material composition and manufacturing process. This product utilizes unsaturated polyester resin as the matrix material and high-performance glass fiber as the reinforcing material. During production, these materials undergo a series of processes including precision interlacing, resin infusion, compression, and heating to form an integrated plate-shaped composite material (FRP grating).
In the final product, the resin mixture accounts for 67% of the weight, while glass fiber constitutes 33%. This specific ratio forms the foundation of the product's performance. The resin matrix provides the grating with outstanding corrosion and chemical resistance, while the high-performance glass fiber delivers unmatched structural strength and rigidity. This synergistic effect enables the final grating product to maintain lightweight properties while offering exceptional load-bearing capacity and durability [high strength, impact resistance, corrosion resistance, flame retardancy, slip resistance, and aging resistance].
Product Feature
Core Advantages and Performance Characteristics
1. Its lightweight yet high-strength properties significantly reduce installation and transportation costs while minimizing load requirements on supporting structures. Compared to steel grating of equivalent strength, it typically features lower self-weight—a critical advantage in construction scenarios involving manual handling or elevated operations.
2. Resin-molded construction provides outstanding corrosion resistance against acids, alkalis, salts, and other chemicals, making it an ideal replacement in highly corrosive environments like chemical plants, wastewater treatment facilities, and offshore platforms.
3. Cutting and drilling openings in the grating panels is extremely straightforward, achievable using handheld cutters or standard hacksaw blades. Cut edges remain intact without fraying or compromising structural integrity. This on-site customizable cutting capability significantly simplifies installation procedures and enhances construction efficiency.
4. The color of molded fiberglass grating is achieved by blending resin-compatible color pigments into the resin matrix, ensuring lasting, uniform coloration. Vibrant FRP grating can enhance your production environment, breaking the monotony of perpetually gray, corrosive settings and adding visual appeal to modern factories.
Product Specification
FRP Grating Square Shape and Application Considerations
1. Standard Square Hole Grating
This series encompasses 24 distinct specifications, representing the most common and versatile grating type. It is typically employed for general applications such as industrial platforms, walkways, and trench covers. Its regular square aperture structure delivers excellent ventilation, light transmission, and slip resistance, making it the standard choice across diverse industrial settings.
2. Micro Square Hole Grating
This series includes 13 specifications characterized by smaller grid dimensions. This design typically addresses specific safety requirements, such as preventing small tools, parts, or other fine objects from falling through the grating openings. Additionally, in commercial or residential buildings, the micro-perforated design prevents fine-heeled footwear like stilettos from becoming lodged in the grating, enhancing pedestrian safety and making it a preferred choice for commercial walkways or landscape platforms.
3. Standard Rectangular Hole Grating
This series offers 10 specifications featuring rectangular openings. This structure may be suitable for specific applications requiring directed fluid or airflow passage, or in certain structural designs where rectangular openings optimize load-bearing capacity and material efficiency better than square openings.
With over 120 molded grating dies, we produce FRP grating in heights ranging from 10mm to 60mm, available in various colors and grid sizes. This facilitates precise selection and project planning for users.

Cutting and Installation
BEIHAI® FRP Grating
BEIHAI® FRP grating is lightweight and high-strength, allowing for cutting without disintegration or alteration of its mechanical properties. Grating panels can be easily cut or perforated using handheld diamond-tipped cutters or standard steel saw blades. Drilling holes in grating is also feasible with electric drills, though turning or tapping operations are not permitted. To minimize cutting waste, conduct a thorough analysis of on-site dimensions and grating specifications prior to cutting to ensure maximum cost efficiency.
Each edge of the grating must be supported by at least 40mm of bearing surface. When grating panels serve as trench covers, no fixing clamps are required since trenches typically feature a stop edge. However, when used as structural walkways, each grating panel must employ at least four fixing clamps, and the bottom of the grating-to-grating connection must be supported by secondary beams.
Three standard clamp types are used for securing grating to frames and connecting grating panels. All clamps are available in stainless steel or hot-dip galvanized finishes.
[ M-Type Clamp ]
[ C-Type Clamp ]
[ L-Type Clamp ]
Used for positioning and securing grating to support materials, providing fixed rotational connection around the perimeter.
Used to connect two adjacent grating panels.
Used for specialized positioning connections between grating and support materials.
