Composition and Materials:

Colors and Finishes:

Standard finish is clear satin anodized. Color powder coating is also available at request.

Product Limitations:

Aluminum extrusions and components are suggested for both interior and exterior use. Aluminum components are characterized by their lightness, strength, corrosion resistance, and high durability leading to a wide range of product forms and extensive use in engineering applications. However, despite its high durability and corrosion resistance, some simple steps should be employed when handling and cleaning aluminum to avoid staining and damage. To protect against damage to the surface of aluminum, avoid scraping against hard or sharp surfaces, do not drag or throw components on their surfaces, and use soft slings when lifting heavy components. Clean regularly to remove any build up or dirt. If left for an extended period of time, grime may cause staining. Clean with plain water with mild soap/detergent or non-etching chemical cleaner.


Aluminum profiles and interlocking components have a 12 month warranty. This warranty does not cover damage due to external causes, including accident, abuse, misuse, failure to follow installation requirements and problems caused by use of parts and components not supplied by Nova Display Systems.
