Materials - a brief education on sign substrates

There are many substrates that are designed specifically for sign fabrication and many more that are intended for other purposes but make good materials for sign fabrication. Listed are many of the materials that we commonly use, if you do not see a material that you are specifying just ask!

HDU - High Density Urethane is one of our preferred materials because of its long life span and machineability which allows us to achieve realistic textures and shapes that mimic other materials which may not be suited for exterior use or overly expensive - you might say it's the Soy bean of sign substrates. HDU is available in several different weights, the higher densities allow for more details and impact resistance but come with a higher cost.

Metals (steel, aluminum, copper, brass, etc)- Aluminum, with a high strength to weight ratio is another fantastic choice for exterior signage. We often route, weld, and paint aluminum for custom cabinets, stands, and other displays. Steel and other alloys which are more susceptible to rust or patina can be used for exterior signage with proper coatings.

Plastics (acrylic, PVC, etc) - Acrylic is another substrate which has many great uses from push through letters to routed & painted elements. Expanded PVC products such as Sintra can be used with limitations - routed pieces and small panels but not large panels as it becomes fragile with age and cold.

Composite Materials - Another favorite material of our are composite aluminum panels such as DiBond. An aluminum skin on two sides of a polyethylene core make a very rigid yet light material. We stick with brands that have a thicker aluminum sheet and have been proven to not delaminate. Cheap brands dent easily and should be considered for temporary signage only.

Eco friendly materials -We have experience with many products that are either recycled or from a sustainable source that make great choices for LEED projects. Bamboo, Solid surface materials (Corian, Paperstone, etc) Hard and soft woods, certain acrylics (3Form), and of course metals and glass.
