Door Series

Aluminium Doors

Sliding, bi-fold, casement, French and frameless corner slider door systems on a thermally-broken aluminium frame — built for a secure, weathersealed close every time.

Aluminium sliding door opening onto a garden
Door Series

An everyday door, engineered for the long run.

Fabricated from 6063-T5 aluminium alloy and powder-coated for long-term finish retention, our door range spans two- and three-panel sliding doors to concertina bi-folds and dual-sash French doors — each on a frame designed to keep working under daily use.

A polyamide thermal break and continuous weatherseal keep every door in the range wind- and water-tight without adding weight to the panel.

Why This System

Built to perform, not just look good.

Secure Locking

Concealed multi-point locking on every panel, not just the lead sash.

Structural Strength

Engineered aluminium alloy rated for high wind load, no steel reinforcement needed.

Thermally Broken

Polyamide break reduces heat and cold transfer through the frame.

Corrosion Resistant

Powder coat finish holds up to coastal and urban air.

Custom Finishes

Any RAL colour or anodized finish to match the facade.

Space-Efficient

Sliding and bi-fold formats need less clearance than a swing door.
