FAQ

Commerical

Do you make Fire Rated frames?


No. Unfortunately we cannot provide fire rated doorframe as JDS Metal Door Frames cannot tag and cannot certify the frames for fire rated compliance in accordance to Australian standards. Although we do supply fire door companies the frames they are manufactured to very specific details which can only be determined by fire door specialist company. Contact our Commercial team here to learn more




Can you supply a frame to suit a 40mm door in a profile other than Modular e.g. Deluxe Frame or RegalFrame?


No. Unfortunately commercial frames can not be manufactured in the Deluxe or Regal profiles. Please see our commercial page to view our available profile range.




Can a standard residential frame have the same non-standard components as a commercial frame?


Yes. Residential frames can have components such as screw fix backing plates, dynabolt fixings, electric strikes etc. If you would like non-standard components please contact our sales team for more information.




Can I use a door that is thicker than 38mm?


Yes. Commercial doorframes can be manufactured to suit thicker doors of 40mm or more. Contact our Commercial Team here to learn more.




If I ask for backing plates on my frame instead of welded hinges are the hinges included?


No. Usually the projects that require backing plates for hinges are commercial projects that would have a Door Hardware company supply all door hardware, including hinges. However, JDS can issue a quote for hinges if required.

Can a residential frame have the same non-standard components as a commercial frame?


Yes. Residential frames can have components such as screw fix backing plates, dynabolt fixings, electric strikes etc. If you would like backing plates please let us know what thickness hinges you are using (2.5mm or 1.6mm).




What are the wall openings?


Standard split and knockdown frames require you to add 40mm to your door height and 40mm to your door width (total width NOT to each side). Example 2040 x 820 = 2080 x 860




What is the back opening?


Your back opening is your wall thickness. For example 90mm brick would be 95mm back opening. However a 90mm stud would be 114mm back opening. 110mm brick would be 114mm back opening and 70mm stud would be 95mm back opening. Please note stud back openings listed suit 10mm plaster/gyprock etc on either side of stud if you are using thicker plaster/gyprock please let us know as your wall thickness will be different to the sizing highlighted.




What are the standard door heights and associated brick coursing?


A standard door is 2040mm high which is 24 brick courses (if your brickie says 25 course they probably want 2040). The next standard door height is 2340mm which is commonly refered to as 28 brick courses. Please ask for clarification from your brickie if you are unsure.




How many hinges do I need?


2040 high doors require 2 hinges 2340 high doors require 3 hinges 920 wide doors require 3 hinges Please be aware that there are a variety of hinges that can be used on any doorframe. There are a lot of factors that can go into this selection including the type of door you are using. If you want more than 3 hinges please tell us their locations. Industry standard for 4 hinges is 2 at the top, 1 in the middle and 1 at the bottom.




What are the locations of the striker plates?


Standard striker plates come with every frame and a located at 1000mm from floor level Deadlock striker plates are an additional striker that upon request is located 1200mm from floor level Trilock striker plates take the place of the standard and deadlock strikers, located 1000mm from floor level Please note that we can put the striker plates wherever you want them and we can also prep for specialised striker plates for electric strikers etc




When do I need 2 striker plates?


Internal and external garage doors require 3 hinges and a deadlock or trilock for extra security. Some insurance companies have this as a requirement in order to insure your home.




When do I need lift off hinges?


All rooms with a toilet that is less than 1200mm from the open door require lift off hinges. The current National Construction Code requirements (2015) for construction of sanitary compartments states the following: Clause 3.8.3.3 Construction of sanitary compartments The door to a fully enclosed sanitary compartment must –
(a) open outwards; or
(b) slide; or
(c) be readily removable from the outside of the compartment, unless there is a clear space of at least 1200 m, measured in accordance with Figure 3.8.3.3, between the closet pan within the sanitary compartment and the hinge position.




What size door can I use?


Residential frames can hold any door that is less than 38mm. Standard doors tend to be 35mm




What are offset ties?


Offset ties are essentially another form of brick tie that is used in the case of a double leaf wall where the frame straddles the cavity. They are used to secure the frame within the cavity. You may also need a cavity flashing for this application




How do I know what side the hinges are on?


There are many different ways that people use to work out their handings. We request that you pull the door towards you like a fridge door and see which side the hinges are on from this. Another way to determine your door handing is to work out which side of the frame the knuckle of the hinge can be seen from




Can I use a different type of lock?


If you would like to use a mortice lock or privacy latch/lock we can make the frame to suit this we just need a sample that we can work with. You will have the sample returned to you once the frame/frames have been made.




What hinges can I use?


Standard loose pin hinges are used on all residential frames unless specified otherwise. Fixed pin hinges are commonly used for garage doors for extra security. Broad butt or 180 degree hinges are used to make doors swing right around the frame. Modular/split/ten bend frames automatically have these hinges as there is no fancy arcitrave for the door to swing around.




What meter box do I need?


Non-rebated meter boxes are used where the double leaf brickwork is 230mm Rebated meter boxes are used where the outside brickwork is 110mm and the double leaf is 250mm




When do I use knockdown or split frames?


Knockdown frames are used only for stud walls. They are installed after the stud wall has been cladded. Split frames can be used for stud walls or brick construction. They are installed after the stud wall has been cladded or after the plaster/gyprock has been put on the brick wall.
