Our view on alu­mi­ni­um and GRP

The choice of material plays a fundamental role in determining the quality of a vehicle’s exterior and interior. Both aluminium and glass-reinforced plastic (GRP) have unique benefits and qualities, depending on their intended use. Our comparison provides clarity when deciding on materials for the sidewalls or roofs of your vehicles. 

Aluminium and GRP in one overview

Choosing the right material not only enhances the desired look and feel of your vehicle but also influences its lifespan, aligning with your specific requirements and preferences. Drawing from our years of experience, we have conducted a thorough comparison. When it comes to the sidewalls and interior walls of a vehicle, we have assessed the performance aspects and summarised the quality, impact resistance, and processing characteristics of both aluminium and GRP in a convenient overview.

Important benefits of aluminium

Sustainability: aluminium is infinitely recyclable; recycling aluminium requires only 5% of the energy used to produce raw aluminium. When considering the full life cycle, its carbon footprint of aluminium is significantly lower than that of glass-reinforced plastic. 

Durability: aluminium is exceptionally durable, even under mechanical stress. Thanks to its elasticity and high yield strength, Euramax aluminium absorbs impacts and retains its shape, lowering the risk of dents and cracks. 

Safety: aluminium offers inherent safety through its unique material properties. When used as the metal body in vehicles, it acts as a natural Faraday cage that safely conducts electrical charges away. Non-flammable aluminium meets the highest EU fire rating (Class A) and does not burn, emit smoke, or release toxic fumes during a fire.

Style: from vibrant solid finishes to luxurious metallics, our broad range of colours and textures enables manufacturers to create a truly distinctive look for their RVs. Thanks to the excellent colour and gloss retention of Euramax coatings, these coated surfaces are protected against fading and discolouration, even after years of outdoor exposure.
