Illuminated Blade Signs for Street Frontages

A flat fascia is visible only when you are almost in front of it. A blade sign solves the problem of the approach view:

• Shops and restaurants on pavements, high streets and arcades
• Clinics, dental practices and professional rooms entered from a street
• Hotels, guest houses and venues that want to be seen from either direction
• Narrow frontages with little fascia space
• Buildings set at a corner where one direction would otherwise see only a side wall

Blade signs do not replace a fascia sign; they work alongside it. They are less effective on a deep forecourt or a setback building where passing traffic is in vehicles, where a pylon is better.

Blade signs vary in shape, construction and how they are lit:

• Lightbox blades: a cabinet with a printed or cut-out face, lit evenly from inside
• Routed-face blades: metal faces with the logo cut out and backed with acrylic
• Letter blades: a shaped panel carrying built-up channel letters
• Shaped and icon blades: a silhouette that represents the trade, such as a tooth, fork or key
• Bracket styles: plain, decorative or minimal, fixed from the wall or hung from a frame

Depth and size are set by the wall, the pavement width and the landlord or municipal limits. Many frontages cap how far a sign may project, so we confirm before design.

Cabinets and brackets are usually fabricated in aluminium or stainless steel, powder-coated or painted in brand colours. Faces are opal acrylic with applied vinyl, or metal with cut-out artwork. Heritage or boutique frontages may suit brass- or copper-toned finishes on the bracket. Double-sided signs are built so both faces match in brightness and alignment. See materials and finishes.

Blade signs are typically lit with LED modules inside the cabinet, giving a bright, even face on both sides. Metal faces with cut-outs create crisp shapes that glow only where the logo is cut. Because a blade sign sits at head height or just above, brightness matters: too bright can dazzle people walking towards it, and too dim disappears behind street lighting. We usually add dimming and a timer or photocell so the sign switches on at dusk and off when you close.

Lighting for a blade sign should also take the nearby fascia into account, so the two do not look mismatched in colour or intensity.

Projecting and hanging signs cover the full family, including unlit and decorative types. Choose an illuminated blade when evening visibility matters. LED lightbox signs are usually wall-parallel and suit a main fascia, while a blade is perpendicular and aimed at foot traffic.

Shopfront signs deal with the whole frontage; a blade sign is one component. For a building rather than a shop, an illuminated monument or pylon may be more suitable for vehicle approach.

• Viewing distance and size: as a rough guide, many designers allow around 25 mm of letter height per 10 m of viewing distance. Blade signs are read at an angle and at pavement distances, so shorter distances and bold simple graphics work best.
• Contrast: choose a face colour that stands out from the building colour behind.
• Mounting surface: the wall must carry the weight and wind load of a projecting cabinet. Brick, concrete and cladding need different fixings.
• Electrical access: power has to reach the bracket, ideally through a concealed route. We note cable paths and isolation at survey.
• Light spill and glare: avoid glare into first-floor windows or neighbouring units.
• Weather exposure: cabinets need sealed joints and drainage; brackets are detailed to reduce water entry.
• Access and approvals: projecting signs over a pavement are often regulated. Structural, electrical and municipal approval matters are checked at survey and design stage and may need the landlord, body corporate or municipality; we do not promise compliance in advance.

• Size, depth and projection
• Single- or double-sided construction
• Face material and artwork complexity
• Metal choice and finish
• Number of LED modules and power supply
• Bracket design and fixing method
• Wall type and cable route
• Access equipment at installation

We provide a written quotation after the survey and design brief.

Wipe faces with mild soapy water and check seals at the top of the cabinet. Check the fixings and bracket periodically, because a projecting sign takes wind loads. Replace failed LED modules rather than leaving a patchy sign. Our signage cleaning and maintenance and LED signage repairs keep blade signs in good order.

We build in metal and acrylic and arrange surveys and installation by appointment across Gauteng. Blade signs suit pedestrian-facing retail and office frontages such as these:

• Signage in Sandton
• Signage in Johannesburg
• Signage in Pretoria
• Signage in Midrand
• Signage in Centurion
• Signage in Rosebank
