Clad truss staircase

Truss construction methods have natural application to commercial-scale staircase designs, but are still relatively uncommon.
Design

The T2 utilises a non-visual truss assembly (see the T1 brochure for an example of a visual ‘feature’ truss design), cladding the structural members in opaque material. The resulting impression is impressive in monolithic aspect. The broad expanse of material following the geometric course of the flights provides the opportunity for creating a striking feature. Clad in raw or painted steel sheet, the stark silhouette of the T2 can invade and dominate a space and provide contrast for more naturalistic surrounds. Clad in timber, the staircase remains a warmer, yet still imposing design, drawing on the natural beauty of timber and the extensive use of angles

Technical

Commercial grade mild steel truss staircase frames are constructed from 50mm SHS. It may be sheeted with pre-finished and treated 3mm sheet metal lining or with structural plywood and pre-finished recycled timber shiplap tongue and groove cladding.
