Widely used in:
Greenlogy TECGrating is widely used for platform (industrial) flooring, stairs, 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 process and assemble.
Application scenarios
FRP molded grating 25*100H25 heavy-duty type is suitable for industrial platforms, walkways, trench covers and equipment operating surfaces that require high load capacity and corrosion resistance. Its 25 mm thickness and 100 mm mesh structure maintain ventilation and light transmission while suiting working conditions that bear heavier loads. For suitability to specific scenarios, please contact us for detailed specifications and a quotation.
Selection guide
When selecting, the actual load, span, support method and corrosive environment should be combined to confirm whether the resin type and grating thickness match. This product is the 25*100H25 heavy-duty type. If you are unsure of the working conditions, please contact us for detailed specifications and a quotation, and our technical staff will help confirm a suitable model.
Product advantages
FRP molded grating features light weight, high strength, corrosion resistance, slip resistance and insulation. Molded forming interweaves the mesh and load-bearing bars into one piece for good integrity. The heavy-duty type enhances load capacity while retaining the corrosion resistance advantages of FRP, making it suitable for areas with higher structural strength requirements. Please contact us for detailed specifications and a quotation.
Inquiry guidance
To learn about the resin type, color, surface treatment and supply information of FRP molded grating 25*100H25 heavy-duty type, please contact us for detailed specifications and a quotation. Please provide your working conditions and quantity requirements, and we will match a solution for you as soon as possible.
Operating environment
- Designed for indoor and outdoor industrial environments, FRP molded grating may be exposed to damp, moisture and intermittent water contact.
- Suitable for areas with chemical splashes, vapors and corrosive media, which are commonly found in process, treatment and utility units; the resin system selected for the grating must match the specific chemicals present on site.
- Suitable for outdoor installations exposed to sunlight and weather conditions, as the fiberglass-reinforced plastic structure using UV-stabilized resin and E-glass reinforcement is designed for long-term outdoor use.
- Used for heavy-duty walkways, platforms, trench covers and stair treads in industrial operating areas; actual loads, support spans, chemical exposure and working conditions must be confirmed with our technical team before ordering.
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.
