Acrylic vs metal signs
Acrylic and metal are the two main materials for permanent signage. One is light and illuminated, the other is heavy and durable. Here is how to choose.
The quick answer
Choose acrylic for illuminated letters and modern interiors. Choose powder-coated metal for heavy-duty outdoor permanence. The two are often combined: a metal frame with an acrylic face.
Side by side
| Feature | Acrylic | Metal (aluminium, steel) |
|---|---|---|
| Weight | Light, easy to mount | Heavy, needs strong fixings |
| Durability outdoors | UV-stable cast acrylic lasts years | Powder-coated metal lasts decades |
| Illumination | Excellent (acrylic face glows with LED behind) | Possible but metal is usually the frame |
| Finish | Glossy, modern, many colours | Brushed, matte, painted, premium |
| Cost | Medium, cheaper for illuminated letters | Medium to high, higher for premium finishes |
| Maintenance | Wipe clean, no rust | Check for rust on exposed edges |
When to pick acrylic
Choose acrylic for illuminated channel letters, reception signs, lobby panels and any sign that needs to glow. Light, versatile and the standard for LED-lit signage.
When to pick metal (aluminium, steel)
Choose powder-coated metal for pylons, monuments, heavy-duty outdoor fascia and prestige building signs. Metal frames also back acrylic faces on large signs.
FAQs
Which is better outdoors?
Powder-coated metal for permanence (decades). UV-stable cast acrylic for illuminated letters (years). Both are outdoor-rated when specified correctly.
Is acrylic cheaper?
Generally yes for illuminated letters. Metal is more expensive but lasts longer for heavy-duty outdoor use.
Can you combine them?
Yes. A metal frame with an acrylic face is the standard construction for large illuminated channel letters and light boxes.
