Star Aluminium Self Levelling Stairs

Star Aluminium self-levelling stairs are an adjustable temporary access solution designed for construction sites where ground levels vary and a single fixed stairway cannot serve multiple access points. The multi-angle design allows the stair height to be adjusted within the specified range, enabling one unit to be used across multiple locations and site stages without requiring a different stair for each application.
The self-levelling base compensates for uneven and sloped ground surfaces, a common issue on active construction sites where levels change constantly between stages of work. By eliminating the instability and access risk created by uneven ground, self-levelling stairs reduce both the time and hazard associated with setting up temporary site access. Aluminium construction keeps the unit lightweight enough for site personnel to handle and reposition without mechanical assistance.
Self-levelling stairs are used in concrete slab construction, formwork access, civil earthworks and general building sites where fast, flexible temporary access is required. The ability to adapt to varying heights and ground conditions makes them a practical alternative to purpose-sized stair units. All systems are backed by a Lifetime Structural Warranty.

Aftercare & Maintenance

All Star Aluminium products are designed and manufactured to Australian Standards for height access and industrial equipment.
Every unit is supplied with a compliance plate and engineering certification.
Our standard products comply with WHS requirements and carry a Lifetime Structural Warranty.
Every month, we recommend that you inspect every product to make sure they are safe for use.
Check the unit's surface and weld points in order to ensure there is no external damage or corrosion from weather conditions that can cause a safety issue.
If any damage is found on the equipment when checking your monthly inspection routine, please mark the equipment as "out of service" and call us so we may discuss what needs to be repaired.

Frequently Asked Questions

How do Star Aluminium self-levelling stairs adjust to uneven ground?

Star Aluminium self-levelling stairs use an adjustable base mechanism that allows each unit to compensate for uneven ground surfaces, slope variations, and changing deck heights without shimming or modification to the surrounding structure. The self-adjusting frame maintains a level stair angle across the full height range of each model, providing consistent step spacing and a stable climbing surface regardless of site conditions.

What height range and width configurations are available?

Star Aluminium self-levelling stairs are available in nine standard models covering heights from 800 mm to 4,000 mm. Width configurations are 650 mm (single-width) and 1,200 mm (double-width) to suit varying traffic volumes and operational requirements. Step configurations range from 6 to 18 steps. Optional landing platforms extend the system to provide stable elevated work areas at heights up to 4,000 mm.

What is the load rating for Star Aluminium self-levelling stairs?

Star Aluminium self-levelling stairs are rated to 2.5 kPa (uniformly distributed load) or 450 kg depending on the model and configuration. The 2.5 kPa rating applies to lighter-duty models suited to personnel access in construction and civil environments. The 450 kg rating applies to heavier-duty configurations where load transfer requirements are higher. Contact the Star Aluminium team to confirm the correct rating for your specific application.

Are optional landing platforms available for self-levelling stairs?

Yes. Star Aluminium self-levelling stairs are compatible with optional landing platforms in four standard configurations: SLS LP 1 through SLS LP 4, covering heights from 1,000 mm to 4,000 mm with platform areas from 1,000 x 1,000 mm to 1,500 x 1,000 mm. Landing platforms are fitted with safety handrails, anti-slip checker plate decking and a compliance plate. They provide stable working areas at height where transitions between stairs and elevated work zones are required.

Are Star Aluminium self-levelling stairs manufactured to Australian Standards?

Yes. All Star Aluminium self-levelling stairs are designed and manufactured to Australian Standards for industrial access equipment. Each unit is fitted with a compliance plate to support site WHS obligations. Manufacturing is covered by the ISO 9001:2015 certified quality management system. All units carry a Lifetime Structural Warranty. Integrated crane lift and rigging points and forklift pockets support efficient relocation between work areas and sites.

What industries use Star Aluminium self-levelling stairs?

Star Aluminium self-levelling stairs are supplied to construction, civil infrastructure, marine and port operations, mining, oil and gas, manufacturing, utilities and government facilities across Australia. Applications include access to elevated plant and structures on uneven ground, temporary stair access during construction where ground levels change progressively, marine vessel boarding where deck height varies with tide, and production line access where floor levels differ between operational areas.
