A Complete Guide to Balustrading in Australia
Balustrades are a crucial architectural feature in both residential and commercial properties across Australia. Whether installed on staircases, balconies, or terraces, they serve both aesthetic and functional purposes. But what exactly is a balustrade, and why is it important? In this guide, we’ll explore the history, types, materials, and benefits of balustrades, as well as the relevant Australian standards you need to know.
What is a Balustrade?
A balustrade is a railing system that consists of a series of vertical posts, known as balusters, which support a handrail or top rail. It is commonly used to enhance safety and add a decorative element to structures such as staircases, balconies, decks, bridges, and terraces.
In Australia, balustrades must meet strict safety regulations outlined by the National Construction Code (NCC) and Australian Standards AS 1170.1, AS 1288, and AS 1657, which govern height, strength, and material requirements to ensure compliance with safety laws.
A Brief History of Balustrades
Balustrades have been used in architecture for centuries, dating back to ancient Greek and Roman civilisations. Traditionally made from stone and marble, they were seen as a symbol of luxury in palaces and public buildings. Over time, modern materials such as glass, stainless steel, and aluminium have become popular choices due to their durability and contemporary aesthetics.
Types of Balustrades in Australia
There are several types of balustrades, each suited to different environments and design preferences.
1. Glass Balustrades
✨ Sleek, modern, and elegant
🌟 Provides unobstructed views and enhances natural light
🌊 Suitable for balconies, pool fences, and staircases
Glass balustrades are highly popular in Australia, particularly in coastal and urban areas, where homeowners and businesses seek a contemporary design. Toughened safety glass (AS 1288 compliant) is required to ensure structural integrity and impact resistance.
2. Stainless Steel Balustrades
⚙️ Durable and corrosion-resistant
🧼 Low maintenance and easy to clean
🏢 Suitable for both indoor and outdoor applications
Stainless steel balustrades, particularly marine-grade 316 stainless steel, are commonly used in coastal regions due to their ability to withstand harsh weather conditions. 304 stainless steel is a cheaper alternative for indoor and mild outdoor settings, though it is less resistant to corrosion in salty or humid environments.
3. Timber Balustrades
🕰️ Classic and timeless aesthetic
🏰 Best suited for traditional and heritage-style homes
♻ Needs consistent maintenance and sealing
Timber balustrades are often seen in heritage-listed homes and verandahs, offering a natural look that complements classic Australian architecture. Today, timber is primarily used in combination with metal balustrades, with the timber most commonly serving as the handrail for a warm yet modern aesthetic.
4. Aluminium Balustrades
💪 Lightweight, durable, and corrosion-resistant
💸 Cost-effective and low maintenance
🏙️ Ideal for external staircases, balconies, and decks
Builders and homeowners across Australia widely use aluminium balustrades for outdoor applications due to their rust-proof nature and affordability. They often apply a powder coating for extra protection and to enhance aesthetic appeal.
5. Mild Steel Balustrades
🛠️ Strong and highly versatile
🎨 Designers create intricate custom designs to suit various architectural styles
🏷️ Suitable for both residential and commercial applications
Mild steel balustrades offer exceptional strength and adaptability, making them ideal for various architectural styles. Powder-coating enhances their durability and provides a range of colour options to match different design aesthetics.
6. Brass Balustrades
💎 Elegant and timeless aesthetic with a gold look
🏡 Common in heritage and luxury properties
♻ Needs regular upkeep to prevent tarnishing
Brass balustrades offer a classic and luxurious appearance, often used in high-end homes and commercial buildings. While they develop a natural patina over time, regular polishing helps maintain their luster.
7. Galvanised Steel Balustrades
⚡ Highly durable and rust-resistant
🌳 Ideal for outdoor and industrial applications
⏳ Low maintenance and long-lasting
Galvanised steel balustrades are coated with a protective zinc layer, making them exceptionally resistant to rust and corrosion. This makes them a popular choice for outdoor environments and high-traffic areas.
8. Wrought Iron Balustrades
💪 Strong and highly decorative
🖼️ Great for heritage homes and intricate designs
🔒 Requires protective coatings to prevent rust
Wrought iron balustrades add an elegant and vintage charm, making them a popular choice in Victorian-style homes and commercial buildings.
Australian Balustrade Regulations
To ensure safety, all balustrades in Australia must comply with the National Construction Code (NCC) and relevant Australian Standards:
Minimum Height Requirements:
- Staircases & Ramps: At least 865mm above the nosing of stair treads.
- Balconies, Decks & Raised Platforms: At least 1,000mm (1 metre) from the finished floor level.
Gaps Between Balusters:
- Openings in balustrades should not exceed 125mm to prevent children from slipping through.
Glass Balustrades:
- Must use toughened laminated glass in compliance with AS 1288 for safety.
Non-compliance can result in significant fines and legal liabilities, so it’s crucial to follow these guidelines.

1. Enhanced Safety
Balustrades help prevent falls and accidents, especially in elevated areas such as balconies and staircases.
2. Increased Property Value
Well-designed balustrades can boost the aesthetic appeal and market value of your property.
3. Durability & Longevity
Manufacturers design modern balustrades to withstand harsh weather conditions and resist wear over time, particularly with stainless steel and glass options.
4. Customisable Designs
Balustrades, whether featuring sleek glass designs or intricate wrought iron details, can be customised to suit any architectural style.
