Aluminium is not only lighter and stronger but it’s also straighter than real wood. Externall supplies lengths of up to 6.5m ensuring every extrusion is true to form. This means building with a perfectly crafted marine grade material that is easier to install and won’t warp over time.


Externall looks better for longer. To ensure your color choice stands the test of time, all of our colors have been rigorously tested to withstand the most extreme environments. Externall advanced paint technology and powder on powder process provides a durable, baked-on paint finish that resists peeling, chipping and cracking. When maintained correctly, Externall colors and finishes will remain as true as the day you bought it.


Choosing a material with sustainability in mind is becoming more paramount. Metal is one of the most recycled materials on the planet and aluminium boasts one of the highest recycling rates of any metal. Externall is 100% recyclable, uses VOC free coatings and lead free finishes resulting in a smaller environmental footprint for us and for you.


Externall is easy to maintain and requires minimal effort to retain its appeal. Follow these simple care and maintenance instructions to keep it looking like new.


Fire resistance and resilience are important no matter where we live. This is where Externall benefits truly surpass the use wood. Externall is a non combustible product that has been manufactured to meet relevant international fire standards.


Externall is made from high quality marine grade Aluminium. Contrary to other metals, Aluminium reacts with the oxygen in the air to form an extremely thin layer of oxide. Though unnoticeable, this naturally occurring layer provides excellent corrosion protection and is self-repairing if damaged. This anodizing process naturally improves its resilience to corrosion in harsh environments.


A topcoat of specially developed, exterior grade paint is baked on to provide resistance to chipping, flaking and blistering to ensure the finish retains its look for longer. Our specialized powder on powder process permeates the entire thickness of the powder coating which means Externall finish is the industry’s leading material in hard wearing wood like products. To ensure the maximum life and appearance from your Externall product we recommend viewing our Care and Maintenance section.


One of the best known properties of aluminium is that it is light, with a density one third that of steel and a weight 50% less than wood when compared equally. The low density of aluminium accounts for it being lightweight but this does not compromise its strength. A lightweight material means low transport costs, easy installation and handling while maintaining structural integrity in all types of environments and conditions.


Externall is perfect for the outdoors. Aluminium is great in direct sunlight as it remains cooler than most other materials. It naturally absorbs heat slowly but releases it quickly. Whether it be a deck, handrail, or any other application, In the heat of the day Externall aluminium remains cool to touch.


Aluminium is impervious to insects, no need to worry about termites or ants affecting the beautiful Externall finish. In contrast to wood, Externall aluminium doesn’t require additional chemical treatments to protect them from pest attack.


Unlike most steel grades, aluminium does not become brittle at low temperatures. Instead, its strength increases. And as it doesn’t absorb water or moisture, Externall won’t warp and expand when exposed to extremely cold conditions.


Aluminium is perfect for wet, damp, shady environments. Unlike wood, Externall is non porous and will not swell, grow mould or mildew when exposed to wet conditions. As it doesn’t retain water, it’s easy to maintain as it doesn’t require regular sealing, making it a more practical solution than wood.
