Metal Frames can be single or double-rebate profiles, or purpose-made to suit the application providing test evidence is available. ASICO metal frames are manufactured in material gauges to suit the application and in-filled as required to match the insulation requirements of the door. Where frames require an infill to achieve the fire rating, thermal or acoustic function, this will be shown in the certification document.
Metal Frames are not usually a problem with steel fire doors because the basic material is non-combustible. If adequately fixed to the supporting structure, they will remain stable almost indefinitely, providing they are not subject to any additional loading.
Steel fire doors can be installed in masonry, protected steel, or stud partition walling systems. The fire door will generally behave better in steel stud partitions than comparable timber door sets, since the steel stud work and the door move in a similar manner when subjected to fire. However, it is essential that the overall arrangement be considered, not just the door set. Approval for installation in partitioning should be covered by the certification or assessment.
