Reinforced Fiberglass
In order to ensure the mechanics and durability of the grating, Shirui uses only high quality non-alkali glass fiber.
| Specification | Category | Characteristic | Applications |
|---|---|---|---|
| E-2400TEX | Alkali-free roving (E glass) | Excellent infiltration performance, firmly bonded with the resin matrix, so that the grating has excellent mechanical properties and corrosion resistance | For high strength and corrosive applications |
Filler
| Filler type | Performance | Applications |
|---|---|---|
| Aluminum hydroxide | Flame retardant, reinforced, oxygen index 28 or above | Flame retardant, smoke suppressing environment |
| Calcium carbonate | Reinforced, proper cost reduction | No fire retardant request |
| No filler, pure resin | Good transparency, corrosion resistance | No fire retardant request, high corrosion application |
Natural Concave Surface
The naturally formed crescent grooves(concave surface) give it good anti-slip properties.
Gritted Surface
The surface of the grating is gritted with quartznds, which makes the anti-slip performance even better.
Closed Covered Surface
The surface of the grating is decorated with checker or gritted plates to prevent dripping of liquid and evaporation of gas.
Smooth Surface
Surface polishing treatment makes it more delicate and beautiful.
Stair Treads
Black sanding plate at the front end is more eye-catching and safer.

Fabrication And Assembly
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.
