Cairns T2 External stairs with perforated panels

The Cairns T2 Block A External Stairs project represents a perfect synthesis of heavy-duty structural fabrication and intricate architectural design. Marcus P. Graham Ironworks Ltd (MPGI) was tasked with detailing, fabricating, and supplying the architectural railing system for a prominent set of external concrete stairs.

To achieve the architectural vision, these heavy-gauge plates required meticulous CNC profiling to create a unique, randomized "scattered" perforation pattern before being folded at the edges for added rigidity and seamless modular joining.

Detailing this project required extreme precision. The MPGI modeling team generated precise flat-pattern drawings to ensure the perforations flowed naturally up the varying pitches of the staircases

To ensure long-term durability against the elements, all fittings, panels, and railings were fully galvanized. The final touch was a sleek RAL 7015 powder-coated finish, a dark slate grey that beautifully contrasts with the surrounding modern brickwork and concrete steps. The final installation seamlessly navigated complex interface points, including precise gap detailing between the stanchions, panels, and adjacent louvers, resulting in an incredibly clean, robust, and visually striking pedestrian access route.
