Projoint DIL NZA is a natural aluminium expansion joint consisting of two interlocking and sliding profiles. Suitable for ceramic floor coverings, this profile is the ideal solution for surfaces subject to heavy traffic with a contraction and expansion compensation up to 2 mm. NZA is caharacterised by its high resistance to loads and traffic, both pedestrian and vehicular (forklifts, pallet trucks and cars). Perforated anchorage flanges guarantee a perfect grip.
