Choosing a signboard material comes down to where the sign lives and how long it needs to last. Here is the honest comparison.
Acrylic (3mm / 5mm)
A glossy, premium plastic with vibrant colour and a substantial feel.
- ✅ Best-looking finish — great for office signs, logos and reception walls
- ✅ Pairs beautifully with standoff mounts for a floating look
- ⚠️ Indoor / sheltered use; heavier
ACP — Aluminium Composite Panel (3mm)
A rigid aluminium-and-polymer sandwich panel.
- ✅ Weatherproof and tough — the standard for outdoor and shopfront signage
- ✅ Stays flat on large sizes
- ✅ Excellent value for durability
KT Board (5mm)
A lightweight foam-core board.
- ✅ Cheapest option — ideal for events, promos and short-term indoor signs
- ✅ Very light, easy to mount
- ⚠️ Not for outdoor or long-term use
Quick recommendation
- Outdoors / shopfront → ACP 3mm
