Chromodek signs are probably the most common outdoor billboard sign.
One big advantage of Chromodek sign above flex-face signs (where we make use of reinforced PVC banner material, which isspanned across a steel frame) is that chromodek signs are more hard-wearing and will withstand the elements for longer. In some cases, for example where new development are advertised, and the signs don't have to be up for more than a year, people will rather make use of the flexface signs.
Chromodek signs are standard 1.225 meters wide an infinte in length. Thus it is important to know that if your sign is wider than 1.2 metres, that two panels will be pop riveted to each other. if your need is a sign of approximately 1.5 metres in width, it will be wise to rather restrict it to 1.225 metres and to accomodate and change your design to rather increase the length than the width.
