Common Mistakes in Aluminium Decking Installation and How to Avoid Them
Installing aluminium decking offers a durable, sleek solution for modern outdoor spaces, but without the proper know-how, costly mistakes can derail even the most well-planned projects. Below, we highlight the most common errors and how you can steer clear of them for seamless project success.
Misjudging the Substructure
One of the most frequent mistakes is failing to assess whether the substructure is suitable for aluminium decking. Incorrect levelling or uneven foundations can lead to instability and long-term issues.
Solution: Conduct a detailed site survey to ensure the substructure meets the necessary requirements.
Incorrect Fastener Use
Using the wrong type of fasteners—or installing them incorrectly—can weaken the decking system. This not only affects the structure’s durability but also compromises its aesthetic appeal.
Solution: Always follow the manufacturer’s guidelines on fasteners, ensuring you use materials specifically designed for aluminium decking.
Ignoring Thermal Expansion
Aluminium decking expands and contracts with temperature changes, so failing to allow for this movement can cause buckling or warping over time.
Solution: Leave the recommended spacing between boards to accommodate thermal expansion, ensuring your decking remains smooth and secure.
Overlooking Bimetallic Corrosion
When aluminium comes into direct contact with other metals, such as steel, it can cause bimetallic corrosion, which may damage the decking system over time. This is a common but often overlooked issue during installation.
Solution: Use appropriate isolating materials, such as separation pads or coatings, to prevent direct contact between aluminium and other metals. This will protect your decking system from corrosion and prolong its lifespan.
