Staircase handrails are one of the most critical safety features in any building, yet they're often an afterthought in the design and construction process. Whether you're working on a multi-storey office development, a retail complex, or an industrial workspace, specifying the right stair handrails is essential to a project's success.
The stakes are high: poorly specified or installed stair handrails don't just fail compliance inspections, they create genuine safety risks for everyone who uses them. Factor in Australia's strict Building Code requirements, the unique challenges of different stair configurations, and the need for durability in our climate, and it's clear why this decision deserves careful consideration.
The good news? With the right knowledge and a quality supplier, you can navigate the options confidently. In this guide, we'll break down everything you need to know about commercial stair handrails: compliance requirements under Australian Standards, material selection, design considerations for different stair types, mounting options, and what to look for in a professional installation.

Why You Can't Just "Wing It" with Handrail Standards
It's easy to see a handrail as just another part of the build. But Australian standards are incredibly specific for a good reason. It all comes down to safety for every single person who uses the building, from children to older Australians and people with disabilities.
The rules are mainly set out in the National Construction Code (NCC). This document is the foundation of building regulations across the country. Sticking to it means your project is legal, safe, and accessible for everyone, including those in aged care facilities or with a disability.
Ignoring these rules is a huge gamble. You could face fines from local councils or have to remove completed work. More importantly, a non-compliant handrail is a genuine safety hazard that can lead to serious falls and injuries in commercial buildings.
The Core Rules for Commercial Handrail for Stairs in Australia
Let's get into the specifics. While every project might have its own small differences, the fundamental rules for handrails on stairs stay the same. These guidelines come from documents like the Australian Standard AS 1428.1, which focuses on design for access and mobility.
Getting the Height Just Right
You've probably walked up stairs where the handrail felt too low or awkwardly high. The code prevents this by setting a strict height range. Your handrail must be between 865 mm and 1000 mm high.
This measurement is taken vertically from the nosing of the stair treads. The stair nosing is the front edge of the step. Keeping the height consistent along the entire flight of stairs is absolutely critical for user safety.
This specific height offers stable support for the average person. It is low enough for shorter people to reach comfortably. It is also high enough to prevent taller people from having to stoop awkwardly.
Clearances and Space: What You Need to Know
A handrail isn't useful if you can't get your hand around it properly. That's why there are rules about the space around it. You need a clear space between the handrail and the wall, which is secured by a wall bracket or a post.
This gap should be at least 50 mm. This lets a person's knuckles pass without scraping against the wall. Think of it as a comfort and safety buffer supported by sturdy handrail brackets.
You also have to think about what's above the handrail. There shouldn't be any obstructions that could stop someone's hand from sliding smoothly along the rail. This is all about giving uninterrupted support when someone needs it most.
Extensions Are a Must-Have
A handrail shouldn't just stop at the first or last step, this is a common mistake people make. Australian standards say the handrail must extend beyond the stairs at both the top and bottom. Proper handrail solutions always account for this detail.
The required extension is a minimum of 300 mm, plus the depth of one stair tread, horizontally past the last stair nosing. It gives someone a point of stability before they take their first step up or as they step off the final step. For a ramp, the extension is a simpler 300mm past the transition point.
This small detail makes a massive difference for someone who might be unsteady on their feet. It is one of the most important accessibility features of a compliant staircase, especially in aged care projects. The handrail must be continuous without a break for the entire flight of stairs.
Terminations: No Snagging Allowed
How a handrail ends is just as important as where it begins. You cannot simply have the handrail pipe end abruptly. This creates an edge that could snag clothing or a handbag strap, or even cause injury if someone falls against it.
The ends must either return to the wall, loop down to meet the post, or turn towards the floor. This is sometimes called a closure bend or a "swan neck." The goal is to create a closed, smooth finish with no dangerous projections.
This rule protects everyone from catching on the handrail, which could easily turn a small trip into a serious tumble down the stairs.
Shape and Grip
Not just any shape will do for a handrail. The profile must be easy to grab in an emergency. A person should be able to get a firm, powerful grip around it without their hand slipping.
For this reason, circular profiles are very common and highly recommended for any stair handrail. If you choose a circular handrail, its mm diameter should be between 30 mm and 50 mm. This size fits comfortably in most hands and is a common dimension for a dowel handrail.
Other shapes, like a 40 mm square profile, can be used, but they must still allow for a secure grip. Large, bulky rectangular profiles are generally not compliant because you can't wrap your fingers around them effectively. It's all about function over form for commercial applications.
Choosing the Right Materials for Your Project
The material you choose for your commercial stair handrail impacts durability, maintenance, and the overall look of the space. While style is important, your first thought should always be compliance and long-term performance. Your choice of building materials needs to stand up to daily use in a commercial environment.
Material | Best For | Pros | Cons |
Stainless Steel | High-traffic indoor/outdoor areas, modern designs | Extremely durable, low maintenance, corrosion-resistant (Grade 316) | Higher initial cost, can show fingerprints |
Galvanised Steel | Industrial settings, outdoor stair, heavy duty use | Very strong, cost-effective, excellent corrosion protection | Industrial appearance, can be rough to the touch |
Timber Handrails | Offices, restaurants, residential common areas | Warm aesthetic, comfortable grip, classic look | Requires regular maintenance, can be scratched or dented |
Powder-Coated Steel/Aluminum | Projects requiring specific color schemes | Wide range of colors, durable finish, versatile | Can chip under heavy impact, requiring rust-prevention repairs |
Stainless Steel: The Modern Workhorse
You see stainless steel handrails everywhere, and for good reason. They are incredibly strong, resist damage, and are easy to clean. This makes them perfect for high-traffic areas like shopping centers, hospitals, and office buildings.
There are different grades to consider. Grade 304 is the standard for most internal applications. But if the handrail is for an outdoor stair, especially near the coast, you'll need Grade 316 for its superior resistance to corrosion from salt spray.
You can get stainless steel in a few different finishes. A brushed finish has a softer, matte look that hides fingerprints, while a polished finish offers a bright, mirror-like appearance. Both are part of the extensive range of handrail systems available.
Galvanised Steel: The Industrial Handrail Choice
For a quality industrial handrail, galvanised steel is an excellent option. This material is coated with a layer of zinc to protect it from rust and corrosion, making it ideal for industrial handrails and outdoor steps. Its durability makes it a heavy-duty choice for warehouses, factories, and external fire escapes.
The rugged, functional appearance of 50mm galvanised pipe might not fit every aesthetic, but its performs well in harsh environments. It's a cost-effective material that promises a long service life with minimal maintenance. This is the go-to for many industrial handrail projects requiring strength and longevity.
Timber: Warmth and Classic Style
A timber handrail brings a sense of warmth and natural beauty to a space. Products like a porta handrail are comfortable to the touch, making them a popular choice in professional offices and restaurants. It offers a classic look that many clients appreciate.
The downside is that wood needs more care than metal. It can be scratched more easily and may require re-staining or sealing over the years. In Australia, hardwoods like Victorian Ash or Merbau are excellent choices for their durability.
Combining a timber handrail with stainless steel posts and fittings can be a great look. It blends the classic feel of wood with the modern strength of steel. Many suppliers offer a wide range of timber options.
Powder-Coated Finishes: Color and Durability
What if you need the stair handrails to match a specific color scheme? This is where powder-coating comes in. This process applies a colored powder to a metal like stainless steel, mild steel or aluminum, which is then baked to create a tough, durable finish.
The color possibilities are almost endless. You can match brand colors, window frames, or other architectural elements perfectly. It provides a very strong finish that is much tougher than regular paint.
The only thing to watch for is chipping from a heavy impact. If this happens on a steel rail, you'll need to repair it quickly to prevent rust from forming underneath, you won't have this issue with stainless steel or aluminium. It is still a very reliable finish for most commercial uses.
Installation and Best Practices
Proper handrail installation is essential for safety and longevity. This process requires careful planning and execution from start to finish.
Before beginning, review the installation guides provided by the manufacturer. It's also helpful to look at case studies of similar projects to understand potential challenges. Taking measurements is a critical first step.
Many suppliers offer modular handrail systems designed for easy installation. These kits often come with a pre-configured base plate, posts, and handrail components for a quicker setup. For a simple, straight run, an easy install system can save significant time in manufacturing.
Professional Help vs. DIY
While some modular systems are straightforward, the responsibility for compliance is serious. For complex staircases or projects in public spaces like care facilities, engaging a professional is always recommended. Installers with a trade experience often have access to a wider range of parts and specialized knowledge.
Professionals are familiar with the specific requirements in their respective regions and can confirm that the installation will meet Australian standards. They understand how to properly secure a base plate to different surfaces and ensure every connection is solid.
A Simple Compliance Checklist
Feeling a little overwhelmed by the rules? It can be a lot to remember.
Here is a simple checklist you can run through on-site to spot-check your work or a new project to confirm you meet Australian standard guidelines.
Is the top surface of the handrail between 865 mm and 1000 mm from the stair nosing?
Is the handrail height consistent for the whole flight of stairs and over each metre length?
Is there at least 50 mm of clear space between the handrail and the adjacent wall?
Is the rail completely free from obstructions from above and on the sides?
Does the rail continue uninterrupted from the bottom to the top of the stairs?
Does the handrail extend past the top and bottom steps as required?
Is there a handrail on both sides of the stair or ramp?
Are both ends of the handrail returned to the wall, floor or have a 180 degree bend so nothing can snag on them?
Is the handrail's profile between 30 & 50 mm in diameter?
Are all handrails securely fastened and able to support significant weight?
