FRP Grating Smooth Surface
FRP grating with a smooth surface is a type of composite structural grating made from fiberglass-reinforced polymer, typically using isophthalic polyester, vinyl ester, or fire-retardant resins. Unlike gritted FRP grating, the smooth surface version has a flat, even finish without an embedded anti-slip layer.
Fiberglass Grating with Flat Surface
Fiberglass Grating with Smooth Surface – a specialized solution for applications prioritizing easy cleaning, foot comfort, or aesthetic uniformity, where maximum slip resistance is not the primary requirement:
Fiber Grating with Smooth Surface
Smooth surface of FRP grating， it is one of the most popular surface type for fiber grating，after manufacture of FRP gratings，we use FRP gridding machine to polish the surface， so make surface smoothly
Smooth Molded Fiberglass Grating
Smooth Molded Fiberglass Grating made with isophthalic polyester, vinyl ester, or fire-retardant resin etc，client can choose the right resin type when order FRP grating
Smooth Surface FRP Grating Use as Solar Walkways
Smooth surface FRP grating is often used in applications where slip resistance is not the top priority, but corrosion resistance, lightweight design, and ease of cleaning are important. it is widely use as walkway applications
FRP Grating Use as Drain Trench
FRP gratings is an excellent choice for use as a drain trench cover, especially in environments where corrosion resistance, lightweight design, and durability are important.
SPECIFICATIONS
FRP grating comes in various sizes to adapt to different application scenarios. The following are some common dimensions and specifications of FRP grating:
✅ Length and width:
Common lengths range from 1 meter to 4 meters.
Widths are mostly concentrated between 1 meter and 1.22 meters.
✅ Thickness:
Depending on the load-bearing requirements and design requirements, the thickness can range from a few millimeters to dozens of millimeters. Common thicknesses are 25mm, 30mm, 38mm, 50mm, 65mm, etc.
✅ Normal FRP Grating Panel Size:
1.22*2.44 meters
1.22*3.66 meters
1*4.04 meters
1x2 meters
✅ Normal FRP Grating Mesh size:
38*38 mm
40*40 mm
50*50 mm
12*12 mm
19*19 mm
✅ In addition, there are some specific examples as follows:
| Std. Mesh Size*Thk（mm） | Applications |
| 38*38*25mm | Suitable for environments with low load-bearing requirements, such as tree pit covers and workshop inspection channels. |
| 38*38*30mm | Suitable for workshop trench covers. |
| 38*38*38mm | Widely used in car washes, car beauty, factory platforms, aisles and other fields. |
| 50*50*50mm | Suitable for large construction sites and offshore oil platforms. |
| 50*50*65mm | Suitable for occasions with high load-bearing requirements. |
Please note that these sizes can be customized according to customer needs, so if you need a specific size or special requirements of FRP grating, it is recommended to contact us for detailed information.

SLIP RESISTANCE PERFORMANCE
Wet/Dry Conditions: Achieves >0.65 coefficient of friction (COF) under ASTM E303 (pendulum test), exceeding OSHA’s 0.5 requirement for walkways.
Oily/Chemical Exposure: Resists degradation better than rubber or epoxy coatings.
Grit Surface: Coarse mineral aggregates (typically aluminum oxide or silica) are bonded into the resin during molding, creating a permanent anti-skid layer.
Concave Advantage: The curved surface naturally directs liquids toward drainage points, reducing pooling and enhancing grip.
FRP GRATING VS. STEEL GRATING
| Item | GRP Grating | Steel Grating |
|---|---|---|
| Corrosion Resistance | ✅ Excellent | ❌/✅ Depends on type |
| Load Capacity | ❌ Moderate | ✅ High |
| Weight | ✅ Light | ❌ Heavy |
| Electrical Insulation | ✅ Yes | ❌ No |
| Fire Resistance | ❌ Limited | ✅ Good |
| Maintenance | ✅ Low | ❌ High |
| Cost (Long-term) | ✅ Lower | ❌ Higher (for carbon steel) |
Installation & Maintenance Warnings
▇ Drainage Alignment: Install concave panels with ≥1° slope toward drains to prevent liquid accumulation.
▇ Cleaning Protocol: Avoid high-pressure washing directly on grit surfaces (risk of dislodging aggregate).
▇ UV Stability: Select UV-inhibited resins if used outdoors to prevent surface resin erosion.
