SPIDA Contributor


The SPIRAL DUCT MANUFACTURERS ASSOCIATION (SPIDA) was formed to promote the use of round duct, spiral duct (spiral pipe) and flat oval duct by informing the public of its advantages, supporting testing and research of round duct and spiral pipe, and providing manufacturers with specialized information necessary to the efficient operation of the business of the members.

Gustafson (Linx Industries, Inc.) has elected to join SPIDA as a Brad Thomas Research Contributor. As such, we support technical research and testing efforts of the organization and have a leadership role. We look forward to playing an active part in the community.
