When vertical space is at a premium, you can’t roll your security door up or down. That doesn’t mean you can’t install a security door, however—it’s simply time to think horizontally with our side-folding security grilles. Alumatec’s ST-12 open-pattern grille is an excellent choice for securing any type of storefront. Side-folding doors and grilles require no headroom and have adjustable roller stems. Their openings can be curvilinear and require no floor track. The ST-12 is one of the strongest and most durable open-pattern curtains in the industry. We manufacture each side-folding security grille using a double-action hinge system and sleeved rods, ensuring that this grille will hold up to the rigors of daily use.
