Saltwater corrodes metals five times faster than fresh water while salty, moist sea air corrodes metals ten times faster than normal humidity air. There are many similar corrosion problems in various industries that challenge steel, wood or other traditional materials. When designing walkways in such corrosive environments, FRP grating walkway is a corrosion-resistant, high-strength, lightweight and non-slip alternative to traditional the steel grating.
Molded FRP grating walkway is the most commonly used in various industries and applications because it is more durable and cheaper than the pultruded FRP grating walkway, and is bidirectional loading. Although the pultruded FRP grating walkway is only loaded in the direction of the bearing bar, it is the right choice if your walkway requires a larger surface area or a stronger grating is required to span a wider walkway.
Resin System – Molded FRP Grating Walkway
FRP grating walkway can withstand unpredictable environments. It is very resistant to corrosion, and has a low potential for sliding under wet conditions.
| Resin Selected Type | ||||
| Code | Resin Type | Flame Retardant Performance | Standard Color | Recommended Use |
| V-CF | Vinyl Resin | Oxygen Index ≥28 | Grass Green, Yellow, Gray, Orange | Acid, Alkali Solvent And Other Corrosive Environment |
| V-CR | Vinyl Resin | Oxygen Index ≥35 | Dark Gray, Black | High Flame Retardant Requirements And High Corrosion Resistance |
| I-IF | Isophthalic Resin | Oxygen Index ≥28 | Grass Green, Yellow, Gray | More Economical Than The Above Two, And Excellent Acid Resistance, Moderate Alkali Resistance And Solvent |
| I-FF | Isophthalic Resin Food Grade | Oxygen Index =26 | Yellow, Light Grey | Mainly Used In Meat And Food Processing Plants, Waterworks |
| O-AF | O-Benzene Resin | Oxygen Index ≥28 | Green, Grey, Yellow | General Acid And Alkali Resistant Environment |
