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. After much R&D and working with our filtration customers, Wallner Expac introduced X-Mesh®. It’s a patented light-gauge expanded metal specifically developed for filter media backing that is favorable for pleating, and is the industry standard for residential, commercial, and industrial applications.
