Fiberglass grating with a gritted surface is a durable, high-performance flooring material designed for environments where enhanced slip resistance and long-term durability are critical. Manufactured from fiberglass-reinforced plastic (FRP) and embedded with a quartz or aluminum oxide grit on the top surface, this grating provides superior traction even in wet, oily, or chemically aggressive conditions.

Descrizione del prodotto

The gritted surface on fiberglass grating consists of a bonded, abrasive top layer applied during the curing process of the molded or pultruded FRP grating. The grit is typically embedded in a corrosion-resistant resin matrix, ensuring the surface remains firmly attached and functional over years of heavy use. This type of grating is available in a range of resin types, such as isophthalic polyester, vinyl ester, or phenolic, each offering varying degrees of chemical, heat, and fire resistance.

Gritted surface fiberglass grating comes in several mesh patterns, thicknesses, and load-bearing capacities, and can be cut to size for custom applications. Common panel sizes include 1m x 4m or 4ft x 12ft, with thicknesses typically ranging from 25mm to 38mm depending on the application.

Applicazioni

The gritted surface makes this type of grating especially suitable for areas where safety and traction are critical. Common applications include:

• Impianti industriali: Chemical processing plants, refineries, and manufacturing plants where floors may be exposed to oils, chemicals, or water.
• Marine and Offshore Platforms: Docks, ships, and oil rigs benefit from corrosion resistance and anti-slip properties.
• Passerelle e piattaforme: Elevated walkways, mezzanines, and maintenance platforms in plants or warehouses.
• Lavorazione di alimenti e bevande: While flat surfaces are often used for easy cleaning, gritted grating may still be applied in less hygiene-sensitive zones where slip resistance is essential.
• Public and Commercial Spaces: Access ramps, stair treads, and utility areas in stadiums, train stations, or airports.
• Water and Wastewater Treatment Plants: High moisture environments where metal grating would corrode or become slippery.

Key Advantages

• Superior Slip Resistance: The gritted top provides excellent traction in dry, wet, or oily conditions, significantly reducing slip and fall accidents.
• Corrosion and Chemical Resistance: FRP materials resist rust, corrosion, and most industrial chemicals, making them ideal for harsh environments.
• Lightweight Yet Strong: Compared to steel, fiberglass grating is lighter, easier to handle, and reduces installation time and labor costs, yet still offers robust mechanical strength.
• Bassa manutenzione: The material does not need painting or galvanizing and is resistant to impact damage and UV degradation.
• Opzioni ignifughe: Certain resin formulations meet Class 1 flame spread ratings and offer excellent fire resistance.
• Non conduttore: Enhances safety in electrical environments, as FRP does not conduct electricity.
• Long Service Life: The embedded grit maintains performance over time, even under heavy foot traffic or light vehicle loads.
