Products & Services

The standard full sizes are 1.22×2.44m, 1.22×3.66m and 1×4m.

Customization is available within the range of standard full sizes. For sizes exceeding the standard range, the grating needs to be split into multiple pieces.

Yes, it is easy. Mark the required size and cut the grating with an angle grinder. Note that different cutting methods will result in different material losses.

Standard full-size gratings come with full edge trimming. For customized sizes, edge trimming is not universal and includes three-side trimming, opposite-side trimming and adjacent-side trimming. If the customized size is exactly cut to the hole position, there will be no edge trimming. You can consult our customer service for the nearest edge-trimmed size or opt for edge sealing (edge sealing is charged separately per meter).

No, they are not the same. FRP grating panels are perforated and water-permeable, while FRP grating covers are sealed with patterned plates on the surface. Please specify your required type clearly.

The standard thickness of most grating covers is 1mm, and thickening is available upon request.

Common specifications are as follows:

    • 25mm thickness: 38×38×25mm, 25×50×25mm, 25×38×19mm (main grid: 38×38mm)
    • 30mm thickness: 38×38×30mm
    • Corresponding standard sizes: 1.22×3.66m, 1.22×4.04m, 1×4.04m

The grating models include:

    • 25mm series: 25×38×38, 25×40×40, 25×43×43, 25×50×25, 25×38×19
    • 30mm series: 30×38×38, 30×40×40, 30×50×25
    • 38mm series: 38×38×38, 38×40×40, 38×38×19
    • 50mm series: 50×50×50, 50×40×40, 50×38×38, 50×100×100
    • 65mm series: 65×52×52

For national standard grating: the upper rib width is 7mm and the lower is 5mm. For non-national standard grating: the upper rib width is 6mm and the lower is 4.5mm. A slight upper and lower deviation is normal for molded grating during demolding.

The main components are resin, yarn, color paste and stone powder. 191 resin and 7 bags of stone powder are used for conventional production.

There are various resin types available (e.g., 196 resin, 3301 resin, 901 resin). Please inform us in advance if you have special requirements such as acid and alkali resistance, corrosion resistance and high temperature resistance, and we will select the appropriate resin type for you.

FRP grating is a handcrafted product made by skilled workers with no mature mechanized production line yet. The grating is woven by crisscross yarns: excessive yarn layers will expose white yarn or small holes on the top, while fewer layers will be fully impregnated with resin. Excessive resin may cause small cracks on the top resin layer down to the yarn layer. These minor defects do not affect the service life and normal use of the grating.

The front of FRP grating is smooth and flat. The back has fiber filaments, which is not as aesthetically pleasing as the front (similar to the bottom of a car), but the product is still economical and durable.

Other

The standard full sizes are 1.22×2.44m, 1.22×3.66m and 1×4m.

FRP products generally require no maintenance. To protect customers, we offer a three-year shelf life.
