Widely used in:
Greenlogy TECFRP grating is widely used for industrial platform floors, stairs, walkways and platforms. Using FRP grating offers many advantages: 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 38*152H38 is suitable for operating platforms, walkways, trench covers and stair treads in petrochemical, power, wastewater treatment and marine engineering fields. Its corrosion resistance, light weight and high strength deliver excellent performance in humid, acid and alkali corrosive environments.
Selection Guide
Selection should consider load requirements, service environment (corrosive media, temperature) and safety needs (such as flame retardancy and anti-slip). Different resin types (such as orthophthalic, isophthalic, vinyl ester and phenolic) provide different corrosion resistance and flame retardancy, and can be selected according to specific working conditions. Contact us for detailed specifications and selection advice.
Product Advantages
FRP molded grating offers advantages such as light weight and high strength, corrosion resistance, anti-slip performance, insulation and maintenance-free operation, and colors and sizes can be customized on request. Its unique mesh structure makes installation and cutting easy, suitable for various complex applications.

Service Environment
- Molded FRP grating 38*152H38 is suitable for outdoor and indoor service environments in industrial plants, and can replace steel grating where humidity and chemical corrosion shorten service life.
- The isophthalic, vinyl ester and bisphenol A polyester resin systems specified above are suitable for continuous contact with acidic, alkaline and saline media in chemical, wastewater treatment and coastal facilities.
- The E-glass fiberglass reinforcement and ATH / PR filler contents listed in the material table give molded grating dimensional stability under humid and wet conditions, along with rot resistance and corrosion resistance.
- The phenolic resin grade (MP-5) in the raw material list is suitable for areas with low toxicity and high flame retardancy requirements, such as tunnels, offshore platforms and confined spaces where fire safety requirements are relatively high.
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.
