Design
The P1 staircase design embraces a particularly broad range of visual styles, since it is defined by a structural PFC stringer frame entirely clad in other materials. As the photographs in this document demonstrate, architects and designers can let their imagination off the leash with respect to form and material types. High quality stone and polish timber inline cladding may be used to clad the PFC members with a sumptuous and graceful finish.
Most balustrade types are suitable for use on the P1, but certain designs style do go together naturally, and the G1 and G2 (fully and semi- framed panel balustrade, respectively) work particularly well with P1. This is because the cladding required on the top face of the stringer members naturally serves as the bottom rail of the balustrade.
Technical
The main structural work of each flight is performed by two opposed PFC members. In U or L shaped staircases, cross bracing using minor members of a lighter gauge may be employed. Plates required for fixing to structural floor or wall faces are generally inset and welded to suit the PFC profile. Where continuing stringer members are joined, mitre welds are used, but right angle joins are commonly approached via a bolted connection.
