Perforated paper is easy to tear. Perforated side-folding security doors are another story. The PFS perforated side-folding door from Alumatec stands apart thanks to its perforated aluminum panels. Its advanced design uses perforations to provide protection against reach-through theft and vandalism while maintaining a clear view of your products and merchandising. In addition to surpassing competitors in both strength and durability, we manufacture each PFS using adjustable roller bearings and stems to aid with uneven surfaces and to help maintain clearances after installation. Accommodating any interior or exterior application, this accordion-style perforated side-folding door promises sophisticated security and performance.
