Wallner Expac

Wallner Expac designs, engineers, and manufactures expanded metal for use in air and fluid filtration, as well as other industries including architecture, construction, energy, and more.

Founded in 1959, Wallner Expac is the founder and leader in manufacturing expanded metal used in pleated filters. Since its introduction in 1975, this application replaced the need for welded wire, distinguishing Wallner Expac as an industry leader. Through continued innovation and technology, Wallner Expac introduced X-Mesh®, the patented industry standard in filter media backing for residential, commercial, and industrial applications.

Evolving from a simple shop to a state-of-the-art, world class manufacturing entity with over 100,000 square feet across four locations, Wallner Expac employs a skilled work force and a dedicated management staff dedicated to meet the evolving needs of the expanded metal landscape.
