Raw material introduction
Resin type
Code | Resin type | Flame retardancy | Recommended applications |
|---|---|---|---|
MP-5 | Phenolic type | Oxygen index up to approximately 80 | Low toxicity, high flame retardancy; fire safety is very important for such applications |
VEFR-25 | Vinyl ester type | Oxygen index 28 and above | Harsh corrosive environments such as acids and alkalis |
VEFR-10 | Vinyl ester type | Oxygen index 35 and above | Applications with high acid and alkali exposure and high flame-retardant requirements |
IFR-25 | Isophthalic type | Oxygen index 28 and above | VEFR economical type, good performance, resistant to medium-strength acids, alkalis and solvents |
IFGR-30 | Styrene-based, food grade | Oxygen index 26 | Mainly used in meat product and food processing plants |
OFR-25 | Orthophthalic type | Oxygen index 28 and above | General acid and alkali environments |
OCR | Orthophthalic type | Oxygen index below 28 | OFR-25 economical type, no flame retardant requirement |
Coarse glass fiber selection
Code | Coarse sand type | Recommended applications |
E | E-glass sand | For high strength requirements and high corrosion resistance applications |
Filler type selection
Code | Filler type | Recommended applications |
|---|---|---|
ATH | Aluminum hydroxide | Flame retardant, smoke suppression and corrosion resistance applications |
PR | No filler, pure resin type | For high corrosion resistance requirements |

Widely used in:
Greenlogy TEC FRP grating is widely used for platform (industrial) flooring, stair treads, 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 easy, fast and flexible to process and assemble.
Application Scenarios
Molded FRP grating 40*40H25 is widely used for operating platforms, stair treads, trench covers and fences in industries such as chemicals, petroleum, power and wastewater treatment. Its corrosion-resistant properties make it suitable for humid and acid/alkali corrosive environments. Contact us for more detailed application cases.
Selection Guide
Selection requires comprehensive consideration of load requirements, span, corrosive environment and fire rating. Different resin types (such as orthophthalic, isophthalic, vinyl ester and phenolic) suit different working conditions; for example, the phenolic type offers excellent flame-retardant performance. For professional selection advice, please contact our technical team for detailed specifications and quotations.
Product Advantages
Molded FRP grating offers advantages including light weight and high strength, corrosion resistance, anti-slip performance, insulation and maintenance-free operation. Its mesh structure design facilitates installation and cutting, and its long service life can reduce long-term maintenance costs. Contact us for more information on product advantages.

Operating Environment
- Designed specifically for outdoor installations such as walkways, platforms and stair treads, where molded FRP grating is directly exposed to sunlight, rain and temperature changes without the corrosion problems of steel.
- Suitable for indoor plant areas with high humidity, washdown requirements or condensation, because the unsaturated polyester resin and E-glass fiber structure will not rust or conduct heat like metal.
- Suitable for highly chemically corrosive environments—including isophthalic, vinyl ester and bisphenol resin grades that resist acids, alkalis and solvents—making it a common choice for chemical, wastewater treatment and coastal applications.
- The 40*40H25 molded mesh pattern allows air, water and light to pass through, helping to limit water accumulation, debris buildup and heat accumulation on the panel surface during use.
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.
