AS 1657:2018 – Guardrails on Platforms: What Every Designer Should Know

When designing platforms for industrial or commercial use, safety must always come first—and that’s where AS 1657:2018 plays a critical role. This Australian Standard outlines the essential safety requirements for access systems like platforms, walkways, stairs, and ladders.

One of the most important elements of this standard? Guardrails on platforms.

At SolidDraft Design Solutions, we specialize in high-quality 2D and 3D modeling for fixed platforms, stairways, walkways, and ladders. Our designs are always tailored for compliance, innovation, and fabrication—with AS 1657:2018 at the core of every project.

What Are Guardrails and Why Do They Matter?

Guardrails are barrier systems installed on the edges of platforms to prevent falls from height. They’re not just optional add-ons—they’re essential components for protecting workers and maintaining workplace safety compliance.

According to Safe Work Australia, falls from heights are a leading cause of workplace injuries and fatalities. Installing compliant guardrails significantly reduces that risk.

AS 1657:2018 Guardrail Requirements for Platforms

Here’s what AS 1657:2018 requires when it comes to guardrails on platforms:

✅ When Are Guardrails Required?

Guardrails must be installed on any platform or walkway where there is a risk of falling from a height of more than 300 mm.

This includes:

• Raised work platforms

• Mezzanines

• Access platforms for machinery

• Roof walkways

✅ Guardrail Height Requirements

• Top Rail Height: Between 900 mm and 1100 mm above the platform level

• Mid-Rail: Must be installed halfway between the top rail and the platform

• Toe Board (Kickplate): Minimum 100 mm high, required when there’s a risk of tools or objects falling off the platform

✅ Guardrail Strength & Load Requirements

Guardrails must be capable of withstanding the following forces:

• Top rail: 0.6 kN of force applied horizontally or vertically

• Mid-rail: 0.4 kN

• Toe board: 0.15 kN

These load requirements ensure that the guardrail will hold up under pressure and usage over time.

Common Guardrail Design Mistakes to Avoid

🚫 Gaps wider than 450 mm between rails

🚫 No kickplate on elevated work areas

🚫 Guardrails that are too low or too flexible

🚫 Incorrect spacing on corners or curved sections

With SolidDraft Design Solutions, you can be confident that none of these issues will make it into your final design.
