About Our Commercial Doors

A high quality commercial door should bridge the gap between performance and appearance. At Central Window Systems, our commercial doors do exactly that. They are fully compatible with a range of manual and automatic access systems and can be customised to suit a selection of architectural designs.

Available in standard, PAS 24 and LPS1175 (SR2) options, the GT55 NI aluminium door system is one of the most secure swing doors available on the market. The AluK system has been fully tested with full glazing, no use of steel reinforced panels, as well as with semi-glazing and can be integrated with our ground floor treatment systems.

A versatile commercial door

The GT55 NI can accommodate 6mm – 28mm sealed units, allowing for superior acoustic performance.

Its wide array of hardware means it can be extensively customised, and it comes available in single colour polyester powder coating, as well as textured and anodised finishes.

The choice of pocket or bead glazed delivers easy on site glazing, while its slim 55mm frame maximises the glazed area, allowing for uninterrupted views.

Robust security performance

The GT55 NI is extremely robust, and able to stand up to the rigorous demands of modern commercial usage.

It offers an array of unique security features – incorporating secure glazing, structurally enhanced door frames, and the Adams Rite Sentinel 6 mechanical dead lock.

Both electronic and mechanical access systems can be easily integrated, making the GT55 a hugely versatile commercial door solution.
