How to Choose the Right Signage Material for Your Environment

Not all signs are created equal. A sign that works beautifully inside a shopping centre might fall apart on a Northern Cape roadside. Choosing the right material is just as important as choosing the right design.

Common Signage Materials

PVC Board (Forex)

Lightweight, affordable, great for indoor use and temporary outdoor displays. Not ideal for long-term outdoor exposure.

Aluminium Composite (ACM/Alubond)

The gold standard for outdoor signage. Durable, weather-resistant and available in various finishes. Handles wind, rain and sun without fading.

Corrugated Plastic (Corriboard)

Cheap and cheerful. Perfect for estate agent boards, temporary promotions and short-term outdoor use.

Vinyl

Self-adhesive film for vehicle wraps, window graphics and wall murals. Available in cast (premium, long-life) and calendered (budget, shorter life) options.

Fabric

Stretchable printed fabric for lightbox faces, pull-up banners and indoor displays. Wrinkle-free and easy to transport.

How to Choose

Ask these questions:

  1. Where will the sign be? (Indoor, outdoor, roadside)
  2. How long must it last? (Weeks, months, years)
  3. What weather will it face? (Sun, wind, rain, dust)
  4. What is the budget?
  5. Does it need to be portable?

We help you match the right material to your specific situation. No guesswork required.

Frequently asked questions

Aluminium composite (ACM) with UV-protected print is the workhorse for South African weather. It shrugs off Karoo sun, coastal wind and rain for years.
