4mm Correx® Board Printing offers a lightweight, durable, and cost-effective solution for indoor or outdoor signage. Weather-resistant and easy to install, these rigid boards are ideal for estate agent signs, event branding, safety notices, and short-term promotional displays. NOTE: The maximum size Correx 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.
