Because so many of our sites are refurbishments, both frame and wall openings vary from door to door and this can cause incorrect placing of orders and installation failures. If a door is even a few milometers out, it could mean the difference between the replacement door unit fitting or not fitting. Specialised doors have very little tolerance therefore, it is imperative to get the sizing correct.
Making use of our specialised Consulting services give us the opportunity to advise you on the correct door type and ironmongery to suit your application as well as keeping in line with the regulations as set out by SANS.
Site surveys are carried out to confirm sizing, handing and ironmongery for both quoting purposes and for manufacturing. Unfortunately when we have to replace door frames, not all information can be gathered from a site survey and we are often left to quote blindly. We have no way of knowing if walls are reinforced or if the walls have been poorly constructed with no lintels above the door, this information can only be obtained once we commence with breaking out of old frames.
Fire doors cannot be hung to a standard frame as the make-up of a standard frames varies significantly to that of a fire frame and does not comply with SANS regulations, furthermore fire doors are much thicker than a non-fire rated doors and will stand proud of the frame. Stronghold manufactures ‘Insert Frames’ which in certain instances, can be welded into a standard frame to meet the regulations, saving you time, money and mess. All this will be determined when doing a site walk.
