  • Any size available for the Signs

There are mainly two types of material used for the manufacturing of outdoor signs, namely:

  • Chromadek Steel which is mounted on a square tube frame
  • Reinforced PVC stretched (flexed) over a square tube frame

The popularity of the PVC option is growing fast, because it's lighter and there are no seams, as in the case of chromadek boards and billboards. The welds on bigger chromadek and billboard signs are neat. The bigger sign boards, like the signs erected next to our highways is manufactured of PVC and not chromadek board.
