Composite Signs Deliver Quality

Printing on hybrid plastic/aluminum composite is becoming increasingly popular as people learn more about it. Weighing about half as much as solid aluminum - but with a thicker depth - composite signs are a solid choice for long lasting, high quality outdoor displays that look great over the long haul.

Custom printed composite signs are ideal for free-standing displays that require a more professional presentation and easier maintenance than found with wood. The high dimensional stability of the plastic/aluminum composite substrate makes it absolutely ideal for flush mounting against straight outdoor walls, because even with extended exposure to direct heat and sunlight, the sign will maintain it’s shape and straightness without bowing or distorting.

The extra thickness, resistance to weather and high-end look & feel of composite material make it perfect for outdoor displays where presentation is important. State and National Parks often use composite signs for trail maps that are located throughout the park and for other wayfinding signs that need to be readable and sharp year after year. Other applications such as safety signs, building identification signs, contractor signs, street signs, storefront signs and office signs are just a few more examples of uses for composite signs.

Custom Printed Composite Signs are Often Used For:

  • P-O-P displays
  • Outdoor exhibits
  • Trade Show exhibits
  • Directional / Wayfinding Signs
  • Outdoor kiosks
  • Marquee signage
  • Large graphic pieces
