Australian Standards For Stairs 2024

Complying with Australian Standards for Safe and Functional Stairs

Stairs are a vital part of many buildings, providing access between different levels. But poorly designed stairs can be a safety hazard. The Australian Standard AS 1657-2018: Fixed Stairs provides a framework to ensure stairs are safe, comfortable, and easy to use.

What does AS 1657 cover?

AS 1657 sets out requirements for various aspects of stairs, including:

• Overall dimensions:

  This includes minimum stair width, headroom clearance, and landing sizes.

• Treads and risers:

  The standard specifies the acceptable range for tread depth and riser height to ensure a comfortable and safe walking surface.

• Rise and Go Ratio:

  This refers to the mathematical relationship between a tread’s depth and a riser’s height. AS 1657 ensures this ratio promotes a natural stride length for users.

• Handrails and guardrails:

  The standard outlines specifications for handrail heights, diameters, and clearances to provide proper support and prevent falls.

• Load requirements:

  Stairs must be able to withstand a certain amount of weight, and AS 1657 specifies the minimum live and point loads for different applications.

Benefits of Complying with AS 1657

Following AS 1657 offers several advantages:

• Safety:

  Properly designed stairs minimise the risk of slips, trips, and falls, protecting users from injuries.

• Accessibility:

  The standard ensures stairs are usable for people with varying abilities, promoting inclusivity.

• Durability:

  Stairs built according to AS 1657 are more likely to be structurally sound and last longer.

• Compliance:

  Meeting AS 1657 is essential for obtaining building approvals and avoiding legal issues.

Ensuring Your Stairs Meet the Standard

If you’re planning to build new stairs or modify existing ones, it’s crucial to involve a qualified professional familiar with AS 1657. An architect, builder, or engineer can ensure your stairs comply with the standard and meet all safety requirements.
