Three FD30 steel fire door systems
All of our fire doors are made from steel, certified to BS 476 Part 22 for a minimum of 30 minutes of fire integrity, and supplied with a certificate of conformity for building control. Intumescent seals in the frame expand in heat to close the gap, and the glass is certified fire-rated glass. You choose the system by the frame you want to see: a heavier traditional section, a slim one, or the slimmest we make.
