As the British winter really begins to bite, the performance of external aluminium door finishes becomes critical. Aluminium is highly robust, but still needs a certain level of protection to maintain its strength and aesthetic qualities.
The answer is in the RAL coating it is finished in. RAL colours aren’t just about good looks – they provide essential protection during the UK’s harshest months. The powder-coated finish creates a robust barrier against winter’s most damaging elements: freezing temperatures, coastal salt spray and persistent rain. This protective layer prevents oxidation and maintains the door’s structural integrity when it matters most.
What is RAL?
RAL, the European colour matching system established in 1927, represents the gold standard in colour classification. This standardised approach ensures precise colour matching across all our aluminium products, from our signature AB-60 residential doors to our premium bifold systems.
The RAL colour standard offers hundreds of options, giving specifiers unprecedented choice. Our most popular winter selections include pure white (RAL 9010), anthracite grey (RAL 7016) and jet black (RAL 9005). These classic colours provide timeless appeal, but the RAL design system extends far beyond these traditional choices. From subtle metallic colours to bold statements like RAL orange, the colour space is virtually limitless.
The durability of RAL colours
The winter months present unique challenges for door finishes. Snow and ice can be abrasive, while salt treatments on paths and driveways can cause corrosion. Our RAL colour applications are specifically engineered to resist these seasonal threats. The powder-coating process creates a surface that’s significantly more durable than conventional paint finishes, maintaining its appearance even in the most challenging conditions.
Our aluminium door range includes:
Each product benefits from the RAL design system’s versatility, available in either gloss or matt finishes. For trade professionals, it’s worth noting that our RAL products come with a comprehensive 20-year guarantee. This exceptional warranty covers colour stability and surface integrity, providing valuable reassurance for your clients during specification.
The RAL classic range remains popular for traditional projects, but we’re seeing increasing demand for contemporary colours from the extended RAL design system. These include sophisticated grey variations and modern metallic finishes that complement current architectural trends.
Matching RAL colours
Our powder-coating technology ensures colour consistency across all components, making it easier to match doors with other architectural elements. This uniformity is particularly important in winter when natural light levels are lower and colour variations become more noticeable.
