Wallner Expac is a 100% employee-owned company and North America’s largest manufacturer of light gauge expanded metals for filter media backing. In 1975 we introduced expanded metal as a replacement for the more expensive welded wire used in pleated filters. This innovative solution positioned us as leader in the filtration industry.
Today, Wallner Expac continues to introduce expanded metals for many types of filtrations that are manufactured to your specifications including galvanized steel, aluminum, carbon steel, copper, bronze, titanium, and more.
