Steel Stair Stringers – Prefabricated

Our prefabricated steel stair stringers are hot dip galvanised for superior strength & durability – offering long-term weather resistance and a clean, professional finish. Designed and engineered locally in Brisbane, Queensland, these inclined load-bearing supports form the structural framework for internal or external staircases – securely housing and supporting the treads and risers on each side.

Whether you’re building a small set of stairs up to a deck, or a full flight of stairs to your property’s second storey – our steel stair stringers are available in sizes from 1 to 17 treads and are delivered to you ready to install.
