Processus de fabrication

FRP square tubes are produced using the pultrusion process, which ensures uniformity and high mechanical performance. The process involves pulling continuous strands of fiberglass through a resin bath and then shaping them in a heated die. This results in a consistent, high-quality composite material with superior strength and durability. Various resin systems, including polyester, vinyl ester, and epoxy, can be used to enhance properties like fire resistance, UV resistance, and chemical resistance.

Key Features and Advantages

1. Rapport résistance/poids élevé - Lighter than metals while maintaining excellent structural integrity.

2. Résistance à la corrosion - Withstands exposure to moisture, chemicals, and extreme weather conditions.

3. Electrical Insulation - Non-conductive properties make them suitable for electrical applications.

4. Faible entretien - Requires minimal upkeep compared to traditional materials.

5. Options ignifuges - Available with fire-resistant resins to meet stringent safety regulations.

6. Résistance aux UV - Designed to withstand prolonged exposure to sunlight without degradation.

7. Résistance chimique - Suitable for use in aggressive chemical environments.

8. Ease of Fabrication - Can be easily cut, drilled, and assembled using standard tools.
