Both our 4mm and 6mm Correx® board printing is a great option for short-term advertising that is budget friendly. We use a lightweight corrugated plastic board which can be nailed, screwed or glued. This is a very popular material for uses such as lamp post signs, estate agent boards and placards. NOTE: The maximum size board available in one piece = 1220mm x 2440mm. Sizes above this are not a problem, but will require a join when fitting. This is commonplace when fitting large signage.
