Perforated mild steel balustrade: 100 Mount Street, North Sydney

About this project

Perforated mild steel balustrade panels manufactured by Arrow Metal have helped to transform the fire stairs at North Sydney’s tallest commercial building from functional to focal point.

Unlike a typical fire escape, the stairs at 100 Mount Street, North Sydney, are a key architectural feature. Complementing the building’s cross-braced, glazed exoskeleton facade, the glass-enclosed stairwell is the main access for each office level of the 42,100 square-metre building – which means it not only had to meet all safety regulations but also achieve the architect’s aesthetic vision.

Perforated mild steel balustrade creates safe and stylish stairs

To create the balustrade for 100 Mount Street’s signature stairs, the Arrow Metal team perforated over 300 mild steel panels in pattern P246 – a classic in-stock round shape design which features 9.5mm diameter holes in a staggered pitch, with 40% open area.

Each perforated panel was individually designed and profiled by our expert team to fit its place on the stairwell. This involved careful adjustment of the pattern to ensure that the holes were always parallel to panel edges for a uniform appearance. Selected panels were also folded, for an exact pattern match and fit on site.

Panels were powder coated by our customer after delivery, creating a light and bright feature that matches the modern interior of the prestigious 35-storey boutique building.
