SHEILD ROCK Slotted Strut Channels (41x21 mm) are the preferred choice for support and suspension systems requiring high fastening flexibility within limited spaces. These channels feature regularly distributed longitudinal slots, allowing for quick and easy installation of nuts and accessories at any position. Due to their low profile (21 mm), they are ideal for installing cable trays, lighting systems, and small service pipes under suspended ceilings or in narrow corridors, ensuring the required structural strength through high-quality steel manufacturing in various thicknesses.
