The K25 Punched offers a lighter alternative to our standard K25 aluminum security shutter. Utilizing a single-wall extruded aluminum slat with rectangular punch-outs, it provides a sleek design with optional glazing.

Similar to all K25 aluminum roller shutters, the K25 Punched combines lightweight construction with robust strength. Operating quietly and needing minimal maintenance, this compact roller shutter is ideal for medium-security applications, including homes, reception desks, bars, and offices.
