Substrate Material Types

Aluminum Blanks

Aluminum sheeting meets or exceeds ASTM 5052-H38 specifications and is .081" thick. Traffic signs use this specification to meet Transportation Standards, unless otherwise stated for non-critical traffic signage or commercial applications. All aluminum blanks come with pre-drilled holes for mounting, and rounded corners.

Meets or Exceeds ASTM 5052-H38, 0.081" Thickness

Crezone (HDO) Wood

Crezone HDO (High Density Overlaid) board is extremely durable exterior type plywood with a weather-resistant resin overlay bonded to the wood by heat and pressure. This process fuses the molecules of the overlay with the fibres of the wood to form a bond as strong as the wood itself. In many instances, overlaid HDO plywood has proven a more durable sign material than metal. HDO plywood is resistant to the elements with no danger of rust or corrosion. It is typically used for larger signs, or uncommon sizes made-to-order.
