Classification of Sign Boards: Complete Guide by Purpose, Material, Lighting & Application

How Sign Boards Are Classified

A single sign board can belong to multiple classifications at the same time.

For example, a hospital emergency sign may be:

• Safety signage by purpose
• Indoor signage by location
• Illuminated signage by lighting
• Acrylic signage by material
• Permanent signage by duration
• Institutional signage by industry

This multi-layer classification is useful because signage is rarely defined
by only one characteristic.

4. Decide whether illumination is required.
5. Select suitable materials.
6. Understand the installation method.
7. Check environmental exposure.
8. Identify applicable safety or government requirements.
9. Determine maintenance needs.
10. Evaluate lifecycle cost, not only initial cost.
