Widely used in:
Greenlogy TEC FRP grating is widely used for platform (industrial) flooring, stairways, walkways and platforms. Using FRP grating offers many advantages: good weather resistance, low maintenance cost, long service life and good slip resistance. In addition, FRP grating is simple, fast and flexible to fabricate and assemble.
Application scenarios
FRP molded grating 38*38H30 is suitable for corrosive environments such as chemical plants, wastewater treatment and marine engineering, and can also be used as platforms, walkways, trench covers and other applications requiring slip resistance and corrosion resistance. Its lightweight, high-strength characteristics make it an ideal alternative to conventional metal grating.
Selection guidance
When selecting, consider the resin type (such as orthophthalic, isophthalic and vinyl ester types) to suit different corrosion resistance requirements, and choose the appropriate grating thickness and mesh size according to load requirements. For detailed technical parameters and selection advice, please contact us for professional guidance.
Product advantages
This grating features excellent corrosion resistance, light weight and high strength, slip resistance, insulation and easy installation, along with low maintenance cost and long service life. The molded process ensures dimensional stability and a smooth surface, and colors can be customized on request.

Service environment
- This FRP molded grating is molded from unsaturated polyester resin (including orthophthalic, bisphenol and phenolic types) combined with glass fiber, and can be used for indoor and outdoor installation.
- Molded mesh structures with a specific open area are typically used in industrial plants and process areas where corrosive media, moisture and humid atmospheres are present.
- For installations exposed to specific chemicals, temperature or humidity conditions, please select a resin type that matches the actual service environment (for example, phenolic type may be chosen where low toxicity and high flame retardancy are required).
- Please contact us for the complete parameter table and to confirm the resin grade and glass fiber content suitable for your operating conditions.
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.
