12-Step Aluminium Self Levelling Stair | Construction Sites

Maintenance crews and site supervisors rely on the SLS650x12 to provide stable, temporary access in demanding environments. This heavy-duty aluminium stair unit is built for Australian construction and industrial worksites where ground levels are rarely flat. It serves as a robust alternative to standard ladders when a wider, more stable footing is required for workers carrying tools or equipment to elevated above the ground.

The unit handles the challenge of uneven terrain through an adjustable design that allows the stair angle to be set between 37 to 45°. This flexibility means the user can configure the stair to suit specific access points without compromising stability. Each tread features high-visibility yellow anti-slip bull nosing, which provides clear edge awareness and increases grip during ascent and descent. With a 650 mm wide tread configuration, it is specifically suited for single-file traffic flows in space-restricted areas, reducing the risk of slips while keeping the footprint compact enough for tight workshops or plant rooms.

This model features 12 steps and an adjustable height range between 1800 mm and 2750 mm. The powder-coated yellow finish ensures the unit remains visible across busy sites. It is a fit for any operation requiring variable height access on unstable surfaces. Site managers needing adaptable temporary stairs should choose this model.
