Materials
Material choice should follow the environment.
For normal outdoor use, 304 stainless steel is often a strong default. For coastal or chloride-rich exposure, use 316. Aluminium is efficient when weight and cost matter; brass is chosen primarily for appearance and premium positioning.
| Material | Best fit | Main advantage | Watch-out |
|---|---|---|---|
| Aluminium | House signs, flat panels | Lightweight and economical | Less premium feel |
| 304 Stainless | General business signage | Durable architectural finish | Not ideal for harsh marine exposure |
| 316 Stainless | Coastal / pool / marine | Higher corrosion resistance | Higher material cost |
| Brass | Professional plaques | Premium traditional appearance | Surface will age unless protected |
