Widely used in:
Greenlogy TEC FRP grating is widely used for platform (industrial) flooring, stairways, walkways and platforms. Using fiberglass reinforced plastic grating offers many advantages: FRP grating has good weather resistance, low maintenance cost, long service life and good anti-slip performance. In addition, FRP grating is simple, fast and flexible to process and assemble.
Application Scenarios
FRP molded grating 50*50H25 is commonly used for operating platforms, walkways and trench covers in corrosive environments such as chemical, electroplating and wastewater treatment, and is also suitable for marine engineering, ship decks and other applications requiring salt-spray resistance. Its 25 mm thickness balances load-bearing capacity and light weight, making it suitable for medium- and low-load pedestrian walkways or equipment supports. For selection advice for specific working conditions, please contact us.
Selection Guide
Selection should comprehensively consider the resin type (such as orthophthalic, isophthalic, vinyl ester, etc.), grating thickness, mesh size, load requirements and operating environment. Different resins emphasize different properties such as corrosion resistance and flame retardancy; for example, isophthalic resin has better water resistance, while vinyl ester resin resists strong corrosion. We recommend that you provide specific application conditions, and our technical team will assist you in choosing the right product.
Product Advantages
FRP molded grating features light weight and high strength, corrosion resistance, anti-slip, insulation and maintenance-free performance, with a long service life and convenient installation. Its mesh structure allows fluids to pass through, reducing water accumulation and debris buildup. Compared with metal grating, FRP grating is more durable in wet and corrosive environments and requires no regular painting.
Inquiry Guidance

Operating Environment
- The 50×50 mm mesh, 25 mm thick FRP molded grating is designed for indoor and outdoor use in industrial facilities, including weather-exposed walkways, platforms and stair treads.
- The isophthalic, vinyl ester and bisphenol A unsaturated polyester resin systemsmolded FRP grating can withstand the humid, wet and chemically corrosive atmospheres encountered in processing plants, water treatment and chemical handling areas.
- Its corrosion-resistant fiberglass reinforced plastic construction is suitable for locations where weak acids, weak alkalis or salts may be present, helping to extend service life compared with conventional materials.
- For detailed temperature limits, chemical resistance tables or load tables, please contact us to request the full technical data sheet.
Custom Cutting
Need panels that fit, or cut to shape? We custom cut FRP grating and profiles to your drawing: panels cut to size or to shape (corner cuts, cutouts), cut edges sealed with resin, and pre-cut and pre-drilled to drawing before shipping. See the custom cutting services.
