Colours & Finishes
DTW aluminium aluminium sliding patio doors are available in any RAL colour to any BS/RAL specification, with powder coat applied under Qualicoat-certified conditions for consistent, durable results. Standard lead times apply to the most common specifications; bespoke or dual-colour finishes are available with extended lead times.
Slimline sliding doors are often specified with a matt or textured finish in darker tones to maximise the contrast between frame and glass.
A physical colour sample service is available on request. DTW can also match existing powder coat colours using spectrophotometer analysis where replacement or extension work requires continuity with existing frames.
