Hinged Fire Doors

Stronghold Fire Doors are manufactured strictly in accordance to SANS 1253:2003 edition 3 specifications for fire doors and fire shutters and will provide a rating of up to two hours.  The fire retardant slab (core) sandwiched between various types of wood, steel or laminate is constructed from a reinforced insulated material which acts as a fire retardant in a case of fire. The ironmongery fitted to a fire door is key to the integrity of your fire door and should be fire rated. Non-fire rated ironmongery could cause your door to fail in case of a fire.

How to Determine the Handing of Your Fire & Escape Doors
Handing refers to the direction of the door swing as it is opened.

Your Door Handing is always determined from the PULL side which is also the side where the Hinge Knuckles are visible.

 

Door Handing for Single Doors

If you use your Left hand to pull the door towards you – Left Hand

If you use your Right hand to pull the door towards you – Right Hand

 

Door Handing for Double Doors
Double Doors have an Active Leaf and a Passive Leaf. When ordering doors always refer to the handing of the active leaf.

If you use your Left hand to pull the active leaf towards you – Left Hand Active
If you use your Right hand to pull the active leaf towards you – Right Hand Active

 

NOTE:

It is difficult to change the handing of your door once it is hung or installed therefore, its important that we get this right.  Fire & Escape Door must always open towards the direction of escape, there are however exceptions and when doors are opening in, it will not affect how you order your doors, but it will affect how we need to install the ironmongery. Ironmongery will always be fitted for doors opening out, unless otherwise specified.

Reinforcing the core and strategically inserting various preps to take ironmongery is paramount to the longevity of our doors.

Elements

Standard fire door finishes will not stand up to harsh environments and therefore, needs to be protected to prolong the life of your door. All external doors must be cladded with Galvanised or Stainless Steel Sheeting and full surround channel to protect the edges.
