Description
Steep Stairs signs warn of fall hazards on staircases where gradient or step height presents injury risk. Designed to AS 1319 specifications, the yellow and black triangle format is instantly recognisable to all workers. Available in corflute, polypropylene, Colorbond steel, and vinyl in four sizes to suit stairwells from small internal stairs (225×300 mm) to large external staircases (600×900 mm). Fade-resistant inks withstand Australian weather. Reflective finishes enhance visibility in poorly lit stairwells. Trade customers benefit from bulk pricing and fast Australia-wide dispatch.
Final sign type, wording, size, placement and material depend on the site risk, project specification and applicable jurisdiction. Confirm the requirement with the relevant WHS adviser or regulator.

Frequently asked
Where exactly should I position the sign on a staircase?
Mount at eye level just above the top step or at the entrance to the stairwell. This gives users adequate notice before they commit to the descent.
What size is typical for internal office stairs?
Available sizes are 225 x 300mm (Small), 300 x 450mm (Medium), 450 x 600mm (Large), 600 x 900mm (Extra Large). Viewing-distance notes are a practical selection aid, not a substitute for checking the approach distance, lighting, mounting position, wording and site risk assessment.
Do reflective signs work in daylight?
Reflective grades provide different visibility performance. Choose the grade required by the project specification and site conditions, and confirm any road, traffic or high-risk requirement with the relevant authority before ordering.
Can I order multiple signs for a multi-level building?
Yes, and bulk orders qualify for volume discounts. Let us know the total quantity and we'll provide a tailored quote for your project.
How do I clean or maintain the sign?
Wipe with a soft, damp cloth using mild detergent. Avoid abrasive cleaners or high-pressure water on vinyl or polypropylene. Steel signs can handle more robust cleaning.
