Double-sided aluminium backing boxes provide visibility from both directions, making them ideal for suspended signage, corridor displays and free-standing installations. Their rigid profiles deliver a professional finish for LED-illuminated signs.

Single-Sided Backing Box Profiles

Single-sided aluminium backing box profiles are designed for clean, wall-mounted signage installations. These slim but rigid profiles create a flush finish against any surface while housing vinyl, ACM panels or fabricated lettering. Ideal for retail storefronts, reception areas and interior wayfinding, they offer a professional, modern edge for LED-ready signage.

The 35mm single-sided aluminium backing box profile is ideal for slim ACM panels, vinyl graphics and compact LED signage. Its shallow depth creates a clean, low-profile finish for reception areas, shopfronts and interior wall displays.

Suspended or Projecting

The Vogue 65 profile is perfectly suited for suspended or projecting signage where visibility from both directions is essential. It can be bolted to a bracket or sub-structure for added stability and is designed to carry the extra weight of LED illumination and rigid face panels.

Smart Design for Longevity and Maintenance

Backed by rigid aluminium construction, SignBox backing boxes can be fitted with ACM (Aluminium Composite Material) faces for a clean, weather-resistant finish. ACM provides a smooth surface for vinyl graphics, fabricated letters or LED signage, without visible fixings.

For installations requiring internal access, optional service doors can be added to accommodate PSUs, LED drivers and wiring. This ensures easier maintenance, better airflow and long-term reliability while keeping the exterior clean and professional.

ACM Face

Rigid ACM faces offer a durable, seamless finish for aluminium backing boxes and protect against outdoor conditions. SignBox profiles also include our unique ‘Glue Groove™’ channel to secure ACM panels cleanly without visible screws.

Service Doors

Add service doors to house power supply units and LED drivers inside the backing box. These doors improve heat dissipation, improve accessibility, and simplify maintenance for installers.

Accessories for Secure & Professional Installations

Our accessories range includes ACM faces and heavy-duty mounting brackets designed to support rigid, long-lasting aluminium backing box installations. These components ensure your signage is structurally secure, whether it’s mounted flat to a wall, suspended, or projected for increased visibility.
