Application

Suitable for residential and commercial applications in both low traffic and high traffic environments

Description

The BSF70 HI Folding Door System gives maximum control over the style and operation of the doors. Multiple panels can be added to accommodate the distinctive design specifications of the building, with the option to open-in or out as required. The system’s narrow profile ensures that maximum glazing is achieved, flooding spaces with natural light.


In addition to the inherent strength of aluminium, the BSF70 HI combines security hinges and locking mechanisms with a distinctive heavy-duty roller design to provide the security and reliability demanded in high traffic applications. The system also incorporates a pop out T-handle design that allows for square flush stacking panels when doors are fully open.
