Steel Purlins & Joists

We build variable length tophat sections, short and long spans for decks, sub-floor structures, mezzanines, walk-ways and solar farms. This eliminates non-recyclable timber bearers and joists. We can also build roofing solutions using the purlins and joists.

Our Work


As a local manufacturer of cut to length steel tophats used as bearers, joists and purlins we are in a position to supply and substitute “hard to find” structural timber. Available in depths of 90mm, 150mm, 230mm and 300mm the top hats can easily replace timber joists, bearers and roofing purlins. Structural Greenspan Tophats are an ideal solution for residential or industrial flooring – single or multi story, decks and roof purlins.
