A shimmering geometric monolith in stainless steel, the Z2 immediately commands attention.
Mono-stringer designs such as the M1 and M2 are an ideal option for many situations with their open structure and minimalist design. However, because the structural members and support plates are exposed, they have a bias towards a functional or industrial presentation. In contrast, the structural frame of the Z2 zigzag mono-stringer is entirely concealed behind polished stainless steel zigzag plate. It essentially combines the strengths of the mono-stringer approach with a highly sophisticated and elegant finish. Thus, the Z2 is particularly suitable for modern prestige residences.
By cladding the mono-stringer support structure in a seamless stainless steel shell, the staircase gives the impression that it has been sculpted from a single solid billet of metal. This inspires a feeling of solidity and substance without diminishing the airiness of the mono-stringer design. The highly reflective surfaces in fact add to the translucent qualities of this staircase.
The Z2 combines particularly effectively with a frameless glass or face-fixed balustrade systems, enhancing transparency and emphasising the zigzag stringer feature.
The Z2 is built around two laser cut mild steel core stringers. These are bound together with short lengths of square hollow section steel to form a ladder frame. More lengths of SHS are added to each side of the frame to anchor and support the treads. The core is then clad with 3mm plate stainless steel with all welds ground flush and polished to give a seamless finish. Once the stringer is installed the steps are constructed by screwing blocks of ply between the SHS outriggers and centre sections. The dress wood veneers and nosings are then bonded to these ply cores.
