Your Options

At Network Steel, quality and compliance are our priorities. All our galvanised steel stair stringers are manufactured locally to meet Australian building regulations.

Standard Dimensions: Our standard stringers feature a rise of 175mm and a going of 250mm and come in both hot-dip galvanised and pre-galvanised finishes.

Stringer Length Options: We offer a variety of lengths, ranging from 1 tread up to 17 treads.

Wall Thickness for Strength: The wall thickness of the 100x50mm RHS material increases as the number of threads increases to ensure proper support.

Sold in Pairs or Singles: Steel stair stringers are typically sold in pairs, but we also offer them individually for extra-long treads.

Installation Flexibility: The standard design allows for casting into concrete footings at ground level, or can be custom-made for bolt-fixing to existing concrete or mid-span landings.
