Why aluminium and steel are superior materials

Aluminium and steel represent some of the finest door materials available, offering significant advantages over traditional timber and uPVC alternatives.

Both materials provide exceptional strength-to-weight ratios, enabling slim profiles that maximise natural light intake to provide a healthy home, whilst maintaining structural integrity for decades of reliable performance.

These quality materials offer superior corrosion resistance, ensuring your investment maintains its appearance and functionality throughout London’s varied weather conditions without warping, gaining rust, rotting or requiring regular maintenance like timber doors.
