Nullifire FO230 Slotted Steel Angle - 50x50x1500mm

The Nullifire FO230 Slotted Angle is a purpose-built galvanised steel framing component used to construct structural surrounds for movement-capable fire seals. It provides a rigid, reliable framework to accommodate structural deflection while securing passive fire stopping materials.

• Accelerate installation times: The pre-slotted design minimises the need for time-consuming on-site drilling, allowing you to build and mount frames rapidly.
• Ensure predictable deflection: When correctly installed with guidance rods, this angle framework allows for calculated structural movement without breaking the fire seal.
• Prevent structural corrosion: Manufactured from durable galvanised steel to ensure long-term stability and compliance, even in challenging site conditions.

Designed specifically for use with Nullifire's movement systems in apertures up to 1300 x 1300mm. When constructing frames, pieces are bolted back-to-back to form continuous 'T' sections and mounted to the soffit using FS702 sealant and appropriate fixings. This precise framing is critical to achieving up to EI120 classification when housing double FB750 batts.
