These are movable canopies that allow for the creation of new spaces to expand production departments or to serve as storage areas. 

CTZ mobile side-mounted shelters are movable canopy structures designed to create additional space—whether for expanding production areas, use as warehouses, or as a link between two existing buildings.

These structures are known as CTZ mobile tunnels. They are anchored parallel to the building, leaving existing access points unobstructed; on the side facing the main building, the structure slides along an overhead rail supported by galvanized steel pillars (spaced approximately 5,000 mm apart), while the opposite side slides along a ground-mounted rail.

The trusses—available in single- or double-pitch configurations—are joined in pairs and slide on double-ball-bearing steel wheels. The tracks are mounted on the ground (fixed to a concrete curb or anchored directly to the floor using mechanical or chemical anchors, provided the floor's slope and composition allow it) and on an overhead rail supported by pillars. Standard pillar spacing is up to 5,000 mm, though custom designs can accommodate wider spans, including beams up to 14 meters long.

These mobile tunnels are self-supporting; they are installed independently of the adjacent building to ensure no load is placed on existing structures.

Furthermore, multiple "lean-to" style tunnels can be placed side-by-side, sharing pillars to create structures capable of covering large spans.

Each CTZ mobile side-mounted tunnel can be equipped with a variety of accessories, such as different types of industrial doors (ranging from simple PVC curtains to high-speed doors), automated opening and closing systems, anti-condensation liners, and more.

A wide range of available colors allows for full customization, including the addition of company logos and advertising graphics. All structures are CE certified and manufactured in accordance with the UNI 13241-1:2001 standard, ensuring their safety and quality.
