The Durasub Balliatic Door range offers a level of flexibility rarely found in fire-rated steel doors. Each doorset is purpose-built to meet exact project requirements, with tested solutions available for openings up to 5 m high and 6.8 m wide. This makes the range ideal for complex or non-standard openings where fire performance cannot be compromised. 

​

Available in single and double leaf configurations, Durasub Balliatic Doors are suitable for both internal and external applications. 

​

The doors are constructed from a high-strength composite panel of fibre-reinforced cement mechanically bonded to punched steel sheets on both outer faces. This construction delivers excellent impact resistance, durability, and long-term reliability in demanding environments. 

​

Each Durasub Ballistic Door is bespoke to the client’s exact specification and engineered to withstand projectiles up to 7.62 calibre. Specialised ballistic rated materials and hardware are selected to suit the specific threat requirements of each project, allowing virtually any size or configuration to be achieved while maintaining fire resistance of up to 4 hours. 

​

The doorsets are suitable for installation into all structural wall types. Once installed, they require minimal maintenance and deliver consistent, long-term performance in harsh or high-use environments.
