Signage Materials & Finishes | Aluminium, Acrylic, Vinyl, LED

Material choice is where a sign's lifespan is decided. Most premature failures we are called out to repair — our work or anyone's — trace back to a material specified for the drawing rather than for the exposure.

Aluminium

Our default for almost all exterior fabrication. It does not rust, it takes paint and anodising well, it can be welded and formed, and at the gauges we use it is stiff enough for large faces without excessive framing.

Cabinets use 0.090 in or 0.125 in sheet over an internal frame, seam-welded and ground. Channel letter returns are 0.040 in coil with 0.063 in backs. Where a panel is large enough to oil-can — to ripple visibly under its own stiffness — we either increase the gauge or add concealed stiffeners rather than accept the appearance.

Wrong choice for: anything requiring the mass or feel of cast metal. Cast aluminium or bronze plaques are a different product and we fabricate or source them accordingly.

Acrylic

Sign faces, push-through copy and dimensional letters. For illuminated faces we use 3/16 in sheet, either white with translucent film or coloured through the sheet. Coloured-through sheet costs more and does not fade; translucent film applied to white acrylic will shift over roughly seven to ten years of south-facing exposure.

Push-through copy — acrylic letters projecting through a routed aluminium face — gives the crispest night appearance available and is what we recommend wherever the budget reaches it.

Wrong choice for: anything at risk of impact at ground level. Acrylic is brittle; polycarbonate is far tougher and we specify it for low-level faces and vandalism-prone locations, accepting that it is less optically clear and more expensive.

Vinyl

Cut lettering, window graphics, panel graphics and vehicle work. Cast vinyl for anything curved or long-life, with a seven-year outdoor rating; calendered for flat panel work where the shorter life is acceptable and the saving is real.

Digitally printed graphics are always laminated. Unlaminated print outdoors is a two-season material and we will not supply it for exterior use.

Wrong choice for: a surface that flexes or a substrate that outgasses. Fresh paint needs to cure before vinyl goes on it, and rushing that produces bubbling nobody can fix afterwards.

LED illumination

White LED modules on regulated power supplies, specified to the depth of the cabinet so the face lights evenly instead of showing hot spots. Module spacing and cabinet depth are related; a shallow cabinet needs closer spacing or a diffuser, and getting this wrong produces a sign that looks striped at night and cannot be corrected without opening it.

We specify components with a documented replacement path rather than the cheapest available, because a power supply that cannot be sourced in year six turns a repair into a rebuild. Power supplies are mounted for access, in the raceway or through a service panel, not sealed inside a welded cabinet.

Wrong choice for: reproducing genuine neon. Where a client wants neon we say so plainly — flexible LED neon substitutes are close but not identical, and the difference is visible to anyone who cares enough to ask for neon.

Masonry and stone

Monument surrounds in brick, cut stone or manufactured stone veneer, usually matched to the building. We build these as a sign assembly with a separate masonry surround, so the sign can be serviced or replaced without touching the stonework.

Wrong choice for: any site where the sign copy is likely to change. Masonry monuments are permanent, and a tenant name cut into stone is a liability the day the tenant leaves.

Paint and anodising

Polyurethane enamel over etch primer for painted aluminium, colour matched to a physical sample. Anodised aluminium in clear, champagne, dark bronze and black where the specification calls for it — anodising is more durable than paint and cannot be touched up, which is the trade.
