We recently applied printed aluminium sheets to an existing hoarding in London. Printed onto hoarding grade dibond type material with a gloss laminate anti-graffiti film, this hoarding is built to last and shine for many years to come - many people stop and note down tht web address - it really is great marketing.
As you can see we prefer a step when going down a hill, rather than organically following the land which can lead to a wiggly top strip. Obvious steps in the hoarding provide clean lines and avoid a messy look.
