A balustrade is the complete safety system—the entire assembly including balusters (upright posts/spindles), top handrail, bottom rail/floor, and any infill (glass, cables, etc.). It’s designed as one unit to prevent falls from stairs, decks, balconies, or raised platforms over 1m high per the National Construction Code (NCC) and AS 1170.1.
Timber decks won’t be complete without handrails and balustrades. These barriers assure that your family and guests are protected from accidental falls and slips. Setting them up in your deck will greatly reduce the chances of injury.
In South East Queensland and other parts of the country, balustrades may come in different forms or sizes. In most cases, a specific balustrade system is always available to meet your needs.
When designing or renovating a deck, selecting the right type of balustrades including its handrails, is essential for both safety and aesthetics. Here are some common types, each with unique benefits:
A glass balustrade system offers a modern, sleek appearance, perfect for those who want an unobstructed view. Combined with stainless steel or timber handrails, glass balustrades provide a minimalist and elegant finish. Over the years, structural glass systems have become more affordable, making them a popular option for homeowners who want to maintain an open, airy feel while still ensuring safety. The transparency of glass makes it ideal for decks with scenic views, allowing you to enjoy the surroundings without visual barriers.
Stainless steel balustrades, including stainless steel handrails, are known for their durability and strength. Completely resistant to corrosion, they are perfect for outdoor use, especially in coastal areas where moisture is a concern. This type of system requires minimal maintenance and offers a clean, modern aesthetic. There are also hybrid systems available, where stainless steel is combined with other materials such as glass or timber, providing more design flexibility while maintaining the strength and longevity stainless steel is known for.
Timber balustrades, including timber handrails, offer a warm, classic appearance that complements natural surroundings. Wooden systems can be crafted from a variety of hardwoods, making them versatile in terms of design. While timber may require more maintenance compared to metal or glass systems, its natural charm and timeless appeal make it a popular choice for many homeowners. Wood is especially well-suited for traditional or rustic deck designs, adding an organic touch to outdoor spaces.
This glass balustrade system is perfect when you want to keep the view. These stylish panels don’t require posts at all; the glass is securely held in place from the bottom.
Modern aluminium balustrades offer sleek simplicity and timeless elegance that effortlessly elevates any deck or balcony design.
The 3kN system features stainless steel handrails with larger diameters, designed to withstand significant stress. This type of protective barrier is particularly suited for assembly buildings and public spaces where the handrails experience high usage and pressure. In addition to their strength, 3kN systems offer a polished, industrial look that complements modern architecture.
When choosing the material for your deck’s balustrades, several important considerations should be kept in mind. Each material comes with its own set of benefits and drawbacks, which will affect the overall performance, appearance, and longevity of your deck. Here are some key factors to consider:
Queensland regulations require balustrades to be at least 1 metre high when the deck is more than 1 metre above ground level. Gaps must also be no wider than 125mm to prevent children from climbing through.
Powder-coated aluminium and hardwood (Merbau or Spotted Gum) are the most popular choices. Both offer excellent durability against sun, rain, and humidity with minimal maintenance compared to untreated timber.
