FRP Molded Gratings-FRP Grating,FRP Products,FRP Profiles-Shirui Reinforced Plastic

FRP Molded Gratings

Unsaturated polyester resin as the matrix, high-performance glass fiber as reinforcing material, through the interlocking weave of glass fibers, resin uniformly poured and heated, pressed and made of a panel composite material with many meshes . The weight ratio of the grating will be 67% of the resin mixture and 33% of the glass fiber.

POURING MIXTURES

Pouring the resin mixtures into the mold, the richer resin layer grating will have better anti corrosion performance.
LAYING THE GLASSFIBER

Lay the fiberglass roving crisscrossing into the mold according to the working operation standards, high content of fiberglass leads to high strength of grating.
PRESSING

Press the fiberglass certain times at a certain time to remove the bubbles and make glass solid, so that the fiberglass and resin are completely infiltrated, which makes the grating’s structure dense, without bubbles.

Colorful Appearance, Excellent Performance

The color of molded FRP grating is made by color pigment which is compatible to the resin, so its color is not superficial, thus keeping the gratings overall color lasting longer time.
A brightly colored FRP grating can improve your production environment, changing the constant grayness of a corrosive environment and adding color to a modern factory.
Shirui's molded FRP grating is high strength, impact resistant, corrosion resistant, fire retardant, anti-slip and anti-aging.
It meets or passes ASTM E-84 fire retardant, Anti-slip R13 (AS4586-2013), DNV, ABS, EU REACH SVHC environmental testing or certification.

Full Type Specifications

We have more than 120 molds to produce FRP gratings in different colors, mesh sizes and heights from 10mm to 60mm, of course, as specified by you.
We can also produce other grating sizes smaller than the full panel size according to your requirements.

3.The specification code 38x38x38 refers to the grating mesh size of 38mmX38mm and thickness of 38mm.

Fabrication And Assembly

SIEGRID^® grating is lightweight and strong, and can be cut as per detail request without falling apart and changing its mechanical properties.
The gratings can be easily cut or perforated with a manual cutter equipped with a diamond cutter blade or even with a regular hacksaw blade, the grating can also be drilled with a driller, but not lathed or tapped.
Certainly, in order to minimize the waste during cutting, the size of the site and the size of the grating should be statistically analyzed before cutting to ensure the maximum economic benefit.

At least 40mm wide supporting is needed each side of the grating. When the grating is used as a trench cover, it can be installed without fixing fasteners because the trench is usually left with a stop, but when it is used as an operational walking platform on the structure, at least 4 sets of fixing clips are required for each grating, and the bottom of the connection between the gratings should be supported by a secondary beam.

Three popular standard fixing clamps/clips are commonly used for fixing and connecting gratings to frames and gratings to gratings. All clamps are available in either stainless steel or hot-dipped galvanized versions.

[ M type Clamp/Clip ]

Connecting between gratings and supports, fixed position connection, fixing around.
[ C Type Clamp/Clip ]

Connecting between gratings next to each other.
[ L Type Clamp/Clip ]

Special positioning between grating and support.

Nowadays, low prices are not the only factor attracts many customers anymore. They prefer quality rather than compensate future shortcomings later at high costs.
This requirement is also very reasonable.
We are so proud to offer the best balance relationship between price and performance and are committed to improving the value of our products rather than a momentary low price.
