CE Certified Aluminium Crittall Doors Manufacturer & Suppliers

The Evolution of Heritage Crittall Doors: High-Precision Extruded Aluminium vs. Traditional Steel

The timeless appeal of the Crittall style—originated by Francis Henry Crittall in the late 19th century—stems from its clean geometric grids, minimal profiles, and historic industrial aesthetic. However, traditional hot-rolled mild steel frames present notable engineering liabilities in modern construction, including vulnerability to galvanic corrosion, poor thermal retention, heavy weight loading, and exorbitant bespoke fabrication costs. As a premier CE certified manufacturer, we have re-engineered this classic design using structural 6063-T6 architectural aluminium alloys.

Our aluminium Crittall door systems eliminate thermal bridging through advanced multi-chamber polyamide thermal barriers (PA66 GF25). By precision-milling slim sightlines down to 30mm, we achieve the precise visual cadence of historic steel fenestration while exceeding current European energy benchmarks (U-values below 1.2 W/m²K when combined with low-emissivity argon units). Furthermore, our electrostatic fluorocarbon powder coatings deliver superior Class 2 marine-grade protection against chalking, UV degradation, and coastal salt spray, which easily outperforms painted raw steel.
