What is your standard lead time on frames?
Our lead time on frames varies, but normally sits between 5-12 working days. To save disappointment, it is recommended that you confirm the lead time when placing your order for a more accurate idea of the current lead time.
Do you provide installation of door frames?
No, our core business is manufacturing. We focus on supplying you with the best quality product and technical assistance. Therefore, installation is not an area we work with. Feel free to get in touch with us for more info on our recommended installers.
Can I order a pre-backfilled door frame?
As per the Australian standards, all fire rated frames need to be backfilled. At the current point in time we are unable to pre-back fill our door frames for a couple of reasons. Firstly, backfilling the door frame makes it substantially heavier, which becomes an issue with transportation. Secondly, when the frames are transported, the backfill tends to crack up. Unloading on site is also challenging. For now, the best solution is to back fill them in situ, or as close to the installation site as possible. Click here for more info on backfilling.
Are Lift off Hinges compliant on Fire Door Sets?
No. The Australian Standards state that 3mm is the maximum clearance allowed between the top of the door and the frame. Door sets with lift off hinges require approximately 10mm gap (depending on the hinge installation instructions from the hardware manufacturer). This becomes non-compliant as the gap exceeds what is allowed according to the standards.
For Non-rated door frames, please let us know when you are using lift off hinges, as we increase the door stop on the head by 10mm, to allow for extra gap required. So instead of a 15mm stop, you will get a 25mm stop on the head only.
What are Surefab Steel Door Frames made of?
We manufacture all our frames from Zincanneal. The material gauges we offer are 1.1mm, 1.4mm and 1.9mm. We are also able to provide Galvabond frames upon request.
Can stud clips be used on fire rated door frames?
No, stud clips cannot be used on fire rated door frames as they have not been tested. Instead, we would recommend using either welded stud straps, new gen, or a partition profile frame as your fixing method which is a better quality installation method. Check out our Frame Profiles page for more info.
Do you sell Mullion frames?
Yes we do, a mullion is a section of frame running vertically from the head of the frame to the floor, and enables multiple doors or double door sets to be installed into the one frame. These are commonly used in cupboard applications, where multiple door sets are side by side. They mean that no nib wall is needed between multiple door frames, therefore saving time and money on site. We are able to make a large range of custom configurations, so contact us to discuss options. Mullions are available as a fire rated or non-fire rated frame.
Do you manufacture Four sided frames?
Yes we do. A four sided frame simply means that there is a threshold frame section welded to the bottom of the door frame. These are commonly used as access panels.
Are you able to supply Transom frames?
Yes, we can offer both fire rated and non-fire rated transom frames to suit any custom size requirements. A transom is a length of frame that is welded horizontally between the left and right hand frame stiles. Transoms usually are used where there is a standard hinged door at the bottom, and a glass or timber panel above.
What’s the difference between tubes and countersunk holes?
Countersunk holes are where we punch countersunk holes only (to suit an M10 dynabolt) down the face of the door frame. Tube fixing includes both the countersunk holes, and also metal tubes welded to the back of the holes. The benefits of using Tubes with countersunk holes is that it gives the frame extra stability, and prevents any warping when installing with the dynabolts. They also act as a mortar guard if the frames are to be backfilled (which is required for fire rated or acoustic frames). Bear in mind that tubes usually finish flush with the back of the frame opening (the throat), so you will be unable to have the frame wrapping around the wall if you elect to use tubes. If you would like the frame to wrap around the wall, you would need to go with the Countersunk holes only option. Visit our Frame Profiles page for more info.
