FRP Chequered Plate Gratings
FRP checkered plate grating is made from fiberglass grating and FRP solid cover Plate, The top solid cover has different thickness such as 3mm or 5mm thickness. also the bottom FRP gratings can provide different mesh size,
FRP Grating Checker Plate Gritted Surface
Concave surface FRP grating is a specialized, custom-molded product used when afe walking surface needs to conform to a curved structure.
Fiberglass Grating and Solid Cover Plate
Concave surface can enhance walking safety by increasing surface friction, especially in damp or greasy environments.
FRP Grating With Chequered Plate
Grooved concave surface FRP grating is one type of FRP grating classified by surface type. It has general anti-slip performance and is suitable for various occasions.
FRP Concave Anti-Slip Surface Use as Floor
Concave FRP grating refers to a curved or inward-bent surface that is custom-manufactured to fit specific design or functional requirements. This type of design is often used when the grating needs to conform to the shape of cylindrical tanks, pipes, or other rounded structures. The concave shape can provide better surface contact, improve ergonomics, enhance aesthetic integration, and sometimes reduce the risk of slip or fall hazards on curved walkways.
FRP Stair Treads Slip Resistance Surface
Concave surface is an economical and general-purpose FRP grating panels. When producing FRP grating, it needs to be die-casted, so crescent-shaped grooves will appear on the surface. The crescent surface itself has an anti-slip effect, and the anti-slip and wear-resistant performance is average. This type of surface grating can be used as factory aisles, inspection channel walkways and other places.
SPECIFICATIONS
FRP grating comes in various sizes to adapt to different application scenarios. The following are some common dimensions and specifications of FRP grating:

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

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.
