To frame each site notice, we build a specially designed sign, which is waterproof and vandal-resistant. The sign is constructed from a 3mm aluminium backing with a 6mm protective polycarbonate covering laid on top.

The site notice itself is laminated and secured between the aluminium and the polycarbonate. The unit is then fastened using security fixings which cannot be removed using conventional tools. As appropriate, the sign is secured to a metal pole or stake, drilled into a wall or attached to railings using heavy-duty metal brackets (as illustrated opposite). The end product is a site notice which is protected against the elements, vandalism and sabotage.
