Decking joists are one of the components used in the construction of a deck. 


"What are decking joists?" you may be thinking. Most significantly, why are aluminium subframes becoming the decking of the future? 


What Exactly Are Decking Joists?


Deck beams are an essential part of any bridge project, providing the structural support needed to create a strong and durable deck. These horizontal beams, usually made of wood, steel or aluminium, are arranged parallel to each other and perpendicular to the planks of the tread. 


The primary purpose of decking joists is to evenly distribute the weight and load of the decking and ensure that it remains structurally stable and capable of supporting the weight of people, furniture and other items. They act as a frame on which the decking boards are mounted and provide a stable surface for walking and resting.
Proper joist placement and levelling are critical to deck integrity. The spacing between the joists determines the stability and strength of the deck, preventing ...
... it from sagging or bouncing underweight. It is important to follow the manufacturer's guidelines or consult a professional to determine the proper spacing based on the materials used and the function of the bridge.


It is also important to level the joists to get a level and even surface for the decking. Uneven ceiling joists can result in an uneven deck surface, affecting not only the aesthetics but also the safety and stability of the deck.


When it comes to the types of beams available, wood is the most commonly used material. Wood beams are readily available, relatively inexpensive, and can be easily cut and shaped to meet specific project needs. However, they are prone to problems such as rot, warping, and pest infestation, which can affect the longevity and structural integrity of your patio.


In recent years, alternatives to traditional wooden beams, including steel and aluminium, have become increasingly popular. Steel girders provide additional strength and durability, making them suitable for bridges that require longer spans or heavy loads. However, steel beams can be heavier and more expensive, and may require additional protective coatings to prevent rust and corrosion.


Aluminium beams have shown promise as an alternative to wood and steel. They are lightweight yet extremely strong, making them easy to handle and install. Aluminium joist rot, warping and pests, giving your decking a longer lifespan. Additionally, aluminium beams are often made from recycled materials, making them an environmentally friendly choice.


Traditional Wood Joists Have Issues


Traditional wooden beams have long been a popular choice due to their availability and familiarity. However, it comes with a number of common issues that can significantly affect the lifespan and performance of a decking project. Understanding these issues is key to understanding why aluminium subframes are becoming the future of decking joists.


One of the biggest challenges with traditional wooden beams is their susceptibility to rot and warping. Wood is a natural material that easily rots when exposed to moisture, especially outdoors. Over time, water can penetrate the wood fibres, causing rot and structural instability. In addition, fluctuations in temperature and humidity can cause the wooden beams to warp, resulting in an uneven and unstable decking surface.


Another limitation of wooden beams is the need for maintenance. Wood requires regular waterproofing, staining and treatment to protect it from moisture and maintain its structural integrity. This maintenance can be time-consuming and expensive as it must be performed regularly to maintain the wood's appearance and prevent deterioration. If wooden beams are not properly maintained, it can accelerate their deterioration, resulting in a shorter lifespan and the need for premature replacement.


Fortunately, these problems can be effectively solved by using aluminium subframes for decking projects. Aluminium is a very durable and weather-resistant material that is inherently resistant to rot, deformation and corrosion. Unlike wood, aluminium does not absorb moisture and is therefore rot-proof. It remains stable even in extreme weather conditions and maintains its structural integrity, which ensures a longer lifespan of the bridge structure.


In addition, the aluminium counter frames offer significant advantages in terms of maintenance. Unlike wood, they do not require regular impregnation, staining or protection from moisture damage. Aluminum's inherent resistance to corrosion and decay eliminates the need for ongoing maintenance, saving you time and money in the long run. This low-maintenance feature makes aluminium subframes an attractive option for homeowners and contractors.


The Advantages of Using Aluminium Subframes for Decking


Aluminium subframes have gained tremendous popularity in the decking world due to their many advantages over traditional wooden beams. These innovative designs effectively solve the problems commonly associated with wooden beams while offering unmatched longevity, durability, low maintenance and eco-friendly properties.

Troubleshoot Wood Beams: One of the major disadvantages of traditional wood beams is their susceptibility to decay, warping, and decay from moisture, insects, and the elements. Aluminium subframes are a great alternative as they withstand these issues very well. Aluminium does not rot, deform or degrade over time, creating a strong and durable foundation. This inherent resilience makes aluminium subframes ideal for outdoor environments where moisture and weather can have a negative impact on the wooden beams.

Durability and Durability: When it comes to durability, aluminium subframes are far superior to wooden ones. Aluminium is a durable material known for its exceptional strength-to-weight ratio and resistance to corrosion. It can handle heavy loads and foot traffic without compromising structural integrity. This durability translates into longer decking life and reduces the need for frequent replacements or repairs that are common with wooden beams. Thanks to the aluminium frames, you can enjoy a solid and durable terrace for many years.

Low Maintenance: Maintaining a deck can be time-consuming and labour-intensive, especially when it comes to maintaining wooden beams. Wood must be regularly impregnated, stained and varnished to protect it from moisture and rot. The aluminium subframes, on the other hand, are practically maintenance-free. They do not require staining, impregnation or protective treatment. A simple regular cleaning with mild soap and water is usually enough to keep them in top condition. This maintenance-friendly feature of aluminium subframes not only saves time and effort but also eliminates the cost of ongoing maintenance of wooden beams.

Green Choice: At a time when sustainability is a growing concern, choosing environmentally friendly materials for construction projects is becoming increasingly important. Aluminium subframes are an eco-friendly option for decking. Aluminium is a highly recyclable material that can be reused without sacrificing quality. By choosing aluminium subframes, you help reduce deforestation and the demand for new wood products, thereby helping to conserve forests and natural resources.

Price Comparison


Cost is an important factor to consider when choosing the right joists for your project. Traditional beams have been a popular choice for many years due to their affordability. However, it is important to weigh the investment and long-term savings associated with choosing aluminium subframes.


At first glance, traditional wooden beams appear to be a cheaper option. They are readily available and generally have a lower initial cost than aluminium subframes. However, it is important to look beyond the initial outlay and consider the long-term benefits that aluminium subframes offer.


Consider the initial investment of aluminium subframes. Even if the purchase costs are higher than for wooden beams, they offer exceptional value for money. Known for their durability and longevity, aluminium subframes far outlast traditional wooden beams. They are highly resistant to rot, warping and insect infestation, ensuring your patio will retain its structural integrity for many years to come.


In addition, aluminium frames require minimal maintenance compared to wooden beams. Wooden beams often require regular treatments, sealing, and inspections to prevent rot and decay. On the other hand, aluminium subframes are virtually maintenance free, saving you time and money in the long run. Additionally, the lower maintenance costs associated with aluminium subframes contribute to their overall cost efficiency.


When it comes to durability, the aluminium subframes are second to none.They can withstand a variety of weather conditions, including heavy rain, extreme heat and sub-zero temperatures, without warping or deteriorating.
