Widely used in:
Greenlogy TEC FRP grating is widely used for platform (industrial) flooring, stairways, walkways and platforms. Using FRP grating offers many advantages: FRP grating has good weather resistance, low maintenance cost, long service life and good slip resistance. In addition, FRP grating is simple, fast and flexible to process and assemble.
Application scenarios
FRP molded grating 19*19H30 is commonly used in electroplating, wastewater treatment, chemical operating platforms, walkways and trench covers and other occasions requiring slip resistance and corrosion resistance. Its 19 mm mesh and 30 mm thickness suit areas requiring a certain load capacity and water/air permeability. Please contact us for detailed specifications and quotations.
Selection guide
When selecting, consider the corrosive media, load requirements and installation method of the service environment, and confirm whether the resin type (such as orthophthalic, isophthalic, vinyl ester or bisphenol A type) and the surface slip-resistant form match. If you have special requirements for flame retardancy or chemical resistance, please contact us for detailed specifications and quotations.
Product advantages
Molded grating is integrally formed, with fibers and resin interwoven and distributed, offering light weight, high strength, corrosion resistance, slip resistance and water/air permeability. It is easy to cut and install and has low maintenance cost. Compared with metal grating, it more easily remains stable in damp and corrosive environments. Please contact us for detailed specifications and quotations.
Inquiry guidance
To confirm the applicable resin system, color, surface treatment or packaging method for 19*19H30 molded grating, please provide your application scenario and quantity requirements. Please contact us for detailed specifications and quotations; we will recommend a suitable solution based on your operating conditions.
Service environment
- FRP molded grating 19*19H30 is designed for outdoor exposed environments: the unsaturated polyester resin system (including isophthalic and bisphenol types) resists UV degradation and weathering on walkways, platforms and stair treads.
- It is suitable for damp and wet service environments, and for drainage covers, trench covers and washdown areas where steel grating would corrode.
- The resin matrix and ATH filler enable the grating to be used in chemically corrosive environments such as industrial plants and processing areas; please confirm the specific media with us before selection.
- For the continuous service temperature range, load tables and chemical resistance data, please contact us for the complete parameter sheets applicable to your project.
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.
