This commercial staircase forms part of a wider office and carpark renovation at Saint Georges Bay Road, delivering a robust and refined accessway that balances form and function.

The stair features 200 PFC steel stringers, chequer plate treads, and a 50mm flat bar balustrade and handrail, finished with a durable SPX satin black coating. The paint specification, supplied by Dulux, includes:

Sandblast SA2.5

Zinc metal spray @100 microns + sealer

Epoxy primer @75 microns

Uracryl top coat — 2 coats @50 microns each
— for a total of 275 microns of coverage, offering a 20-year warranty from Dulux for long-term protection in commercial environments.

A fin-style balustrade adds a subtle design edge while maintaining transparency. The stair connects directly to a timber deck, tying into the newly renovated carpark area.

Designed to be highly functional yet visually clean, this stair does exactly what great commercial architecture should — simple, durable, and sharp.
