Terrazzo stair treads from Herrljunga Terrazzo are always tailored to each individual project. In new stairs (e.g. steel or concrete), treads and risers with thicknesses from 30 mm are made unarmoured for bonding to smooth, stable surfaces. (Our XQ-collections and the Starlight collection come in thicknesses from 20 mm.) The panels can be reinforced by bonding two together with an intermediate layer of glass fibre fabric. In stairs where a prefabricated solution is not possible, terrazzo treads and risers can also be cast in situ.
