Alloy selection
Aluminum, 304 or 316 stainless steel, brass and copper offer different appearances and exposure considerations. For coastal or corrosive sites, confirm the alloy and protection with the factory.
Precision-cut metal letters in mirror stainless, PVD gold, baked paint, brass and cast metal — laser-cut for crisp edges and hand-finished to your exact font, size and finish.

When you buy from a trading company, you pay a middleman and wait on someone else's production line. When you buy from SignLumi, you talk directly to the factory that cuts, welds, assembles and wires your signs.
Metal letters combine typography with a material and finish that must suit the actual wall and environment. The same letter shape can look very different in mirror stainless steel, brushed aluminum, painted metal, brass or copper. Buyers should define indoor or outdoor exposure, desired reflection, maintenance expectations and mounting method before approving a finish. Lighting and service access should also be decided early when the letters will be illuminated.
Aluminum, 304 or 316 stainless steel, brass and copper offer different appearances and exposure considerations. For coastal or corrosive sites, confirm the alloy and protection with the factory.
Mirror, brushed, PVD, painted and natural patina finishes change how letters reflect light and age. Approve a physical sample or close reference against the facade rather than relying only on a digital color.
Send vector artwork with outlined text and note the finished height and width. Fine strokes and small counters should be checked at the actual size so the fabricated letter remains readable.
The return depth controls the visible edge and shadow line. It also affects mounting hardware and the space available when the letters include halo or front lighting.
Share the wall material, fixing height and whether the letters need standoffs, hidden fixings or a panel. The installation plan should protect the facade and keep letters aligned.
Halo, front-lit and non-illuminated metal letters are available. For illuminated builds, confirm LED modules, driver location, wiring protection and how components can be reached later.

| Finish | Painted, brushed, mirror, PVD or patina | Sample and facade photo |
| Artwork | Shape, stroke width and spacing | Outlined vector file |
| Mounting | Standoff, hidden or panel fixing | Wall type and dimensions |
| Lighting | Halo, front-lit or none | Night reference and power plan |
| Service | LED and driver access | Maintenance expectations |
We work in 304/316 stainless steel, aluminum, brass and copper, with mirror, brushed, PVD gold, rose gold, titanium, baked paint and natural patina finishes.
Yes — we offer halo backlit and front-lit metal letters with LED, plus non-illuminated options.
Yes. Send your logo or font file, or choose from our library. We laser-cut letters to your exact shape, size and spacing.
Yes. Stainless steel and PVD finishes are corrosion-resistant and hold up outdoors for years with minimal maintenance.
Compare the desired daytime color, reflection, maintenance and surrounding facade. Mirror, brushed, painted, PVD and natural patina finishes behave differently, so approve a sample or close project reference.
Provide outlined vector artwork, the finished letter height, overall width, spelling, spacing and intended installation location. Include a facade photo when proportions or mounting are uncertain.
Mounting options depend on letter weight, wall construction and service requirements. Hidden or standoff fixings can be discussed, but the final method must be confirmed against the wall and installation detail.
