FAQ

There is no "standard" profile when it comes to our doorframes. It all comes to personal preference, please see our products menu for details on each of our profiles.

If you were looking for a 'timber look' frame you would be looking to use our Regal profile. Please look at the photos of our Regal profile to confirm.

If you were looking for a 'classic' or 'rounded' frame you would be looking to use our Deluxe profile. Please look at the photos of our Deluxe profile to confirm.

If you were looking for a 'modern' or 'square' frame you would be looking to use our Modular profile. Please look at the photos of our Modular profile to confirm.

Our main 3 profiles noted above are available to be bricked in or used in studwork. They are only available to suit;

Brickwork: 90mm or 110mm

Studwork: 70mm stud + 10mm liners either side or 90mm stud + 10mm liners either side

If your walls are a different size please contact our team who will be able to assist you in selecting the frame you require; sales@jdsmetaldoorframes.com.au

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).

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

Door Width 820 x Door Height 2040 = Stud Opening Width 860 x Stud Opening Height 2080

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.

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.

When you are creating your stud opening for our Concealed Frame please be aware that the hinges you intend to use can alter the required opening.

If you are using Hirline Hinges your stud opening will need to be your Door Height + 33mm and your Door Width + 25mm.

Example: Door Height 2040 + 33mm = 2073mm & Door Width 820 + 25mm = 845mm

If you are using Concealed Hinges your stud opening will need to be your Door Height + 33mm and your Door Width + 40mm

Example: Door Height 2040 + 33mm = 2073mm & Door Width 820 + 40mm = 860mm

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.

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

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.

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.

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

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

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

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.

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 architrave for the door to swing around.

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

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.

Brickwork is either 90mm or 110mm = 95B/O or 114B/O

Stud walls can be varying sizes so we offer a wider range of back openings in our standard Ten Bend and Regal profiles = 89B/O, 95B/O, 102B/O or 114B/O

Deluxe knockdowns are only available in 95B/O or 114B/O

Split frames are more versatile and offer wider ranges in back openings = 70-85B/O, 85-125B/O, 125-150B/O or 150-200B/O

Negative Rebate frames in residential are only available in a 92B/O

Cavity Slider frames in residential are only available in the 114B/O

If you require a back opening different to the above please contact our Commercial team.

Our cavity slider frames come with the steel cavity unit in either knockdown form (stud work) or fully welded form (bricked in), the frame architrave (Ten Bend, Regal or Deluxe), as well as our high quality track and roller kit.

The kit also includes door stops so you can choose to have your door sitting flush with the wall or sitting out.

The rebated closing stile comes with a blank striker which can be replaced by your builder if you want locking door hardware.

Below is the formula that we use to determine your required stud opening for Cavity Sliders.

Single doors = door width x 2 + 30mm

Double doors = door width x 4 - 25mm

Door height (single and double) = door height + 75mm

Our standard lead time for Residential frames is 2-4 working days depending on what frame you require. We do keep some frames in stock, please contact us to find out which frames we have. Please be aware that even for stock frames we may require payment to hold the stock for you.

Our meter boxes are a stock item and are always available for pick up during our pick up hours.

We also have standard striker plates, deadlock striker plates, standard hinges, lift off hinges, standard striker boxes, deadlock striker boxes, and rubber buffers available from our office during opening hours.

Unfortunately we do not supply the doors themselves only the steel frames

No, unfortunately we don't.

If the striker plate you wish to use matches our dimensions and the hole locations you can swap out our striker plate with your own. Alternatively you can provide us with a sample and we can make the striker plate cutout in the frame to suit your striker plate.

If you wish to use alternate hinges to those we usually weld to our frames you just need to let us know and possibly supply a sample. We can weld a backing plate to the frame in the hinge locations which will allow you to screw your own hinges to the frame.
