Aluminium extrusions, particularly square aluminium extrusions, stand out for their exceptional weather resistance, enduring the elements and retaining their integrity over time. Their inherent qualities and specialised treatments enhance their durability, making them ideal for various demanding outdoor applications.

Corrosion Resistance

The naturally formed oxide layer on aluminium extrusions serves as a protective barrier against corrosion. This oxide layer effectively prevents the underlying metal from interacting with moisture, chemicals, and pollutants in the atmosphere. Moreover, the rigorous anodising process further thickens and hardens this oxide layer, rendering it impenetrable to corrosion.

UV Stability

Square aluminium extrusions exhibit exceptional UV stability, withstanding the damaging effects of sunlight. The aluminium alloy used in their construction resists fading, discolouration, or cracking caused by prolonged exposure to ultraviolet radiation. This ensures their pristine appearance and colour retention over an extended lifespan.

Temperature Extremes

Aluminium extrusions are designed to endure extreme temperatures without compromising their structural integrity. They can withstand both scorching heat and freezing cold without expanding, contracting, or warping excessively. This thermal stability minimises thermal stresses and ensures their dimensional accuracy under varying conditions.

Impact Resistance

Square aluminium extrusions possess excellent impact resistance, absorbing force without fracturing or denting. The inherent strength of aluminium alloys, coupled with the structured geometry of square extrusions, provides exceptional resistance to mechanical shocks and impacts. This attribute is critical for applications involving potential collisions or rough handling.

Chemical Resistance

Aluminium extrusions exhibit remarkable resistance to a wide range of chemicals, including solvents, acids, and alkalis. Their passive oxide layer acts as a barrier against chemical attacks, preventing degradation or leaching of materials. This resistance is particularly advantageous in harsh environments or applications involving exposure to corrosive substances.

Low Maintenance

The combination of weather-resistant properties makes square aluminium extrusions virtually maintenance-free. They require minimal upkeep, as they do not rust, corrode, or deteriorate over time. Regular cleaning with mild detergents suffices to maintain their pristine condition.


The exceptional durability of square aluminium extrusions makes them ideal for a plethora of outdoor applications, including:

РBuilding fa̤ades

– Window frames and doors

– Solar panels and mounting systems

– Architectural Cladding

– Outdoor furniture

– Marine applications

In conclusion, square aluminium extrusions offer superior weather resistance due to their inherent properties and advanced treatments. Their corrosion resistance, UV stability, temperature extremes, impact resistance, chemical resistance, and low maintenance qualities ensure long-lasting durability, making them the ideal choice for demanding outdoor applications.
