Our art-deco style, slimline steel replacement sliding doors are perfect for adding the on-trend steel-look in your home. More affordable than steel, yet secure, insulated and built to last. Perfect for modern houses as well as traditional properties. 

High performance steel replacement sliding doors replace your dated patio doors or add style and elegance to your new extension. Ultra-slim frames combine with artisan glazing bars giving a multiple panel look or industrial styled door. Choose these doors in popular black or any other colour too.  They also come with matching windows or French doors. 

Technology & Design

Our steel replacement sliding doors use slimline exterior sliding doors, customised for the best aesthetics and appearance. The thin aluminium frames and sliding sashes combine with aluminium glazing bars applied to specially designed glass units. 

Two types of sliding doors come in the steel-look style.  The ultra-slim structurally bonded sliding door or the standard slim interlock model.  Both offer impressive appearance, that desirable contemporary or art-deco style and superior performance with high strenght. 

Thermally insulated aluminium profiles combine with high specification glass units for impressive thermal performance and a comfortable room all year round.  Our doors offer discreet components for a cleaner look with one of the best-engineered sliding mechanisms for a quiet and light sliding action. Even the largest door panels are effortless to slide open and shut. 

The design of your new steel replacement sliding doors allows these to be used either as a replacement for old sliding doors or incorporated within a new extension.  The frame and sashes can also completely recess into the structure giving a near frameless appearance.
