3D letters, also known as fabricated or channel letters, can be manufactured using a range of materials depending on the application, environment, and desired finish. We work with specialist fabricators who produce signage using materials selected to suit each project’s performance and design requirements.
Aluminium is the most commonly used material for 3D letter signage. It is lightweight, corrosion-resistant, and suitable for exterior use, with fire rating compliance options available to meet Australian council and building requirements. Aluminium also offers excellent versatility, allowing for painted, powder-coated, or anodised finishes while remaining cost-effective.
Stainless steel is often chosen for premium or architectural signage. It provides a refined appearance, particularly when brushed or polished, and performs well in coastal or high-exposure environments where durability is critical.
Acrylic is frequently used for illuminated 3D letters and channel letter signage. Available in a wide range of colours and opacity levels, acrylic allows light to pass through evenly, making it ideal for internally illuminated signage and branded lighting effects.
Each project has unique requirements. Material selection is guided by factors such as location, exposure, branding goals, budget, and lighting needs, ensuring the finished signage delivers both visual impact and long-term performance.
