Fire fighting and fire protection is a major concern for building designers or architects. Duodex fire shutters are designed to provide stability and integrity for 120/240 minutes during fire. The shutter assembly comprises of four main components - curtain (slats), shutter casing , casing cover & side guides. The curtain (slats) are constructed from a minimum of 0.7mm to 1.2mm thick pre-galvanised steel slats interlocking along their entire length to form a continuous hinge.

Duodex fire shutter was tested at Warrington, United Kingdom. The fire shutters have also been successfully tested at FRIM to satisfy the requirement of MS 1073; Part 1 : 1987 (P) and BS 476 Pt 22 : 1987.
