When it comes to staircase safety, stair nosings play an essential but often overlooked role.

If you are new to staircase safety, you might be asking:

What is Stair Nosing? What are the different types of nosing?

Whether you’re building a new commercial space or upgrading an industrial site, choosing the right stair nosing can significantly impact safety, durability, and compliance.

In this article, we’ll go deep into how stair nosing can to prevent slips, improve visibility, and comply with Australia’s strict safety standards.

What Is Stair Nosing?

Stair nosing is the front edge of a stair tread — the part you step on most.

Nosings are designed to be integrated or installed as separate strips and are often made from materials like aluminium, fibreglass, or vinyl. While it might seem like a small detail, it’s actually a key safety feature that serves several purposes.

• Improve grip and reduce slips
• Highlight step edges for visibility
• Protect stair materials from wear and tear

Beyond ensuring safety, stair nosings also safeguard the stair material from deterioration. The edge of each step is typically the first area to exhibit damage from frequent use. Reinforcing this edge with a nosing significantly prolongs the stair tread’s lifespan, lowering maintenance expenses over time.

For property owners and facility managers, stair nosings provide reassurance. By integrating safety elements that decrease the risk of falls, you can minimize potential liability and show a dedication to workplace health and safety standards.

What Are the Types of Stair Nosing?

Depending on your environment, usage patterns, and visual design preferences, there are a couple of common stair nosing types.

At Traffic Safety Systems, we supply both Architectural and Fiberglass Stair Nosings, each suited to specific applications.

1. Architectural Stair Nosings

Architectural Stair Nosings are perfect for commercial and public settings where safety and aesthetics are equally important.

Usually crafted from aluminium, these nosings can feature anti-slip inserts, contrasting colour strips, and even photoluminescent elements to enhance visibility in low-light conditions.

Architectural Stair Nosings are highly favoured in offices, educational institutions, public facilities, and areas with heavy foot traffic.

2. Fiberglass Stair Nosings

Fiberglass Stair Nosings are designed specifically for industrial environments and “back of house” areas.

Fiberglass Stair Nosings boast high durability and resistance to chemicals, moisture, corrosion, and fire, making them ideal for outdoor stairs or facilities facing tough environmental conditions.

They are lightweight, simple to install, and provide outstanding slip resistance.

Each stair nosing type is designed to meet specific needs, but all of them help create safer, more durable stairs.

What is the purpose of Stair Nosing?

Stair nosing serves a dual purpose:

1. Safety: Reduces the risk of trips and falls, especially on high-traffic stairs or those exposed to moisture.
2. Durability: Reinforces stair edges against wear, extending the life of flooring materials like timber, vinyl, or concrete.

At Traffic Safety Systems, our Fibreglass Stair Nosings are particularly ideal for back-of-house or industrial areas due to their resistance to corrosion, chemicals, and fire.

What are the rules for Stair Nosings?

In Australia, stair nosings fall under the guidelines of Australian Standard 1428.1, which is part of the Australian Standards concerning Design for Access and Mobility.

Although the standard itself does not constitute law, it is cited in the Building Code of Australia (BCA), thereby making adherence compulsory for new constructions and significant renovations.

Below are some essential stair nosing specifications from AS 1428.1:

• Nosings must cover the entire width of the tread.
• A luminance contrast strip, measuring 50–75mm in width, is necessary at the leading edge of each step to enhance visibility.
• The contrast strip should be positioned within 15mm of where the tread meets the riser.
• To prevent visual confusion, the strip must not extend more than 10mm down the riser.
• No part of the nosing should extend beyond the face of the riser.
• The front edge should either form a sharp angle or have a radius or chamfer not exceeding 5mm.
• This guideline ensures stairways are safe and accessible for everyone, including individuals with low vision, mobility challenges, or other accessibility needs.

Can You Do Stairs Without Nosing?

Stain nosing that is purchased for private use (i.e. use on private residential properties) is not required by law but it would be a bad idea not to have it as stairs lacking nosing are harder to notice and offer less slip resistance, therefore heightening the likelihood of mishaps.

According to the NCC, stair design must comply with specific safety and accessibility standards. While it is technically possible to construct stairs without nosings, doing so may not comply with the safety regulations outlined in the NCC. The code typically requires that stair treads have a specific depth and width, and any modifications or alternatives must still meet safety requirements.

What Is a Stair Nosing Strip?

A stair nosing strip refers to the insert fitted into the stair nosing to enhance grip and visual contrast. These strips can be made from materials such as:

• Fibre-Glass
• Anodised Aluminium

These inserts are especially useful in environments with high pedestrian traffic, poor lighting, or special accessibility requirements.

At Traffic Safety Systems, architectural nosings can be supplied with pre-installed strips, or custom inserts can be added depending on your specific needs.

Choosing the Right Stair Nosing

When selecting a stair nosing, consider:

• Environment: Is it industrial, commercial, or residential?
• Foot traffic: High-volume areas need more durable materials.
• Aesthetic: Square or flush profiles for modern spaces; pencil or half-round for traditional appeal.
• Compliance: Ensure the product meets AS1428.1 and BCA requirements.

Installation and Maintenance Tips

Fitting stair nosings is a simple task, yet it demands meticulous attention to detail for optimal results. Always:

• Prepare and fix stair surfaces prior to installation
• Apply structural adhesive or screws for a secure attachment
• Cut nosings accurately to ensure they sit flush
• Adhere to building codes to prevent compliance issues

After installation, regularly clean nosings, particularly in busy areas. Routinely inspect for damage or lifting — replacing worn inserts can sustain grip and safety over time.

Final Thoughts

Investing in quality stair nosing is one of the smartest moves you can make for stair safety.

Whether you’re after compliance, aesthetics, or durability, Traffic Safety Systems offers the right solutions — including fibreglass stair nosings and architectural stair nosings designed for the toughest environments.
