Dibond, a rigid plastic laminated on both edges with aluminium (overall 3 mm thickness) with sign edges appearing black in colour. Dibond is less heavy than aluminium and stronger/more rigid than plastic.

How to fix your 'Mind the step' hazard sign:

Vinyl signs: Simply peel off the backing material from the self adhesive vinyl plastic 'Mind the step' hazard sign, align and fix the sign along the longest side and then rub flat towards the other side taking care to ensure all air bubbles are removed. If you end up with an awkward air bubble just pop the plastic surface gently with a sharp pin and rub in a circular motion to remove the remaining air. Take your time and take care when applying the 'Mind the step' hazard sign as once the adhesive makes contact with the surface, the sign will be destroyed if it is removed.

Rigid plastic, aluminium and Dibond signs: All 'Mind the step' hazard signs made from these materials can be fixed using suitable adhesives or drilled and fixed with screws or nails.
