Fiber Reinforced Polymer (FRP) stair covers are an innovative solution designed to improve the safety, durability, and aesthetics of existing staircases. These covers are fabricated from high-strength fiberglass-reinforced polymer materials and are specifically designed to fit over worn, slippery, or damaged stairs. Offering a non-slip surface and exceptional resistance to environmental and mechanical stresses, FRP stair covers are ideal for a variety of settings, including industrial, commercial, and residential environments.

1. Material Composition

FRP stair covers are engineered using advanced composite materials to ensure long-lasting performance:

• Renfort en fibre de verre: Layers of fiberglass provide the necessary structural strength and flexibility.
• Resin Systems: Polyester, vinyl ester, or epoxy resins offer resistance to chemicals, moisture, and temperature extremes.
• Surface antidérapante: A gritted surface, often embedded with quartz, aluminum oxide, or silicon carbide, ensures excellent traction.
• UV Inhibitors: Optional additives prevent fading and degradation due to prolonged sun exposure, making them suitable for outdoor use.
• Fire Retardants: Fire-resistant formulations are available for compliance with safety regulations.

2. Design Features

FRP stair covers are designed with functionality and safety in mind, incorporating the following features:

1. Surface antidérapante:

1. Preparation:

   • Clean and dry the existing stair surface.
   • Remove loose debris, grease, or dirt to ensure proper adhesion.

2. Measurement and Cutting:

   • Measure the stair dimensions and cut the FRP covers to size using a carbide or diamond-tipped blade.

3. Positionnement:

   • Place the covers over the stairs, ensuring proper alignment with the nosing and edges.

4. Attachment:

   • Secure the covers using adhesive, screws, or clips, depending on the application.
   • Apply additional sealant along the edges for enhanced durability and appearance.

5. Finition:

   • Allow adhesives to cure before use and verify the stability of the installation.

8. Maintenance Guidelines

FRP stair covers are designed for minimal maintenance, but periodic care ensures optimal performance:

• Regular Cleaning: Use a mild detergent and water to remove dirt, grease, or stains. Avoid abrasive cleaners that may damage the gritted surface.
