Direct answer
A steel door frame making machine is a roll forming line that turns coil into finished jamb and head sections: it decoils and levels the strip, punches hinge, lock and fixing holes, forms the profile, then notches and cuts each piece to length. Corner joining, painting and fitting the door leaf are usually separate steps. Start from your jamb and head drawings and hardware layout; we configure the line to them and reply with a written quotation within 24 hours.
The steps from coil to finished frame
Use this table to agree which steps the machine does and which your workshop does.
| Step | Usually done on | What to confirm |
|---|---|---|
| Decoiling and levelling | Roll forming line | Coil weight, width and thickness range |
| Pre-punching hinge, lock and fixing holes | Roll forming line (punch dies) | Hole layout per frame size and handing (left/right) |
| Roll forming the jamb and head | Roll forming line | Rebate, stop and flange dimensions for each section |
| Notching and cutting to length | Roll forming line | Corner notch shape and cut-length list |
| Corner joining (weld, tab or miter) | Usually a separate station | Joining method and a sample corner |
| Painting or coating | Separate finishing line | Pre-painted coil or post-painting |
| Fitting door leaf and hardware | Assembly area | Trial fit with your hinges and locks |
Process sequence based on our Xiamen production base's published door and window frame line (decoiling, levelling, pre-punching, forming, notching, cutting, unloading). The stations in your line are listed in our quotation.
Roll forming line or press brake?
A dedicated door frame roll forming machine pays off when the same sections and hardware pattern repeat every day. A press brake suits small batches and changing shapes but adds handling and separate punching. The detailed comparison is in roll forming vs bending for steel door frames.
Plan the corner before you order the line
Mitred and welded corners, tab-and-slot corners and knock-down frames each need different notches at the cut-off. Decide the corner method and send a sample or drawing, so the notching dies are included from the start. The hardware and corner trial checklist shows how to test it on the first parts.

What changes the price of a door frame machine
We quote by configuration, not from a price list. These items move the price most:
- Number of frame sections (jamb only, or jamb and head) and sizes
- Punching: how many hole patterns and dies, hydraulic or servo press
- Notching and cutting dies for your corner method
- Steel thickness and coating (galvanised or pre-painted)
- Automation: servo feeding, automatic length and hole positioning
- Decoiler, leveller, outfeed table and stacking
- Control system and component brands
- Delivery terms (FOB or CIF), installation and spare dies
Watch: why the profile comes first

Questions buyers ask
What does a steel door frame making machine include?
Typically a decoiler and leveller, a punching station for hinge, lock and fixing holes, the roll forming section, and notching and cut-off. Corner joining and painting are usually separate; the quotation lists exactly which stations are included.
Can one machine make several door frame sizes?
Width changes depend on the tooling design. Some sizes can share rolls with adjustment, others need separate roll sets. Send every size you sell and we confirm in writing which share tooling.
Does the machine make the frame fire rated?
No. Fire rating belongs to the tested door set (leaf, frame, seals, hardware and installation). The machine produces the frame section to your drawing.
How much does a steel door frame machine cost?
It depends on the number of sections, punching and notching dies, automation and delivery terms. Send your drawings and we reply with a written quotation within 24 hours.
What should I send for a quotation?
Jamb and head drawings, hinge, lock and fixing hole layout, corner method, steel thickness and coating, frame sizes, daily output, voltage and destination port.
What to send for a quotation
Send jamb and head drawings (or a sample frame with measurements), the hinge, lock and fixing hole layout, the corner method, steel grade, thickness and coating, the frame sizes you sell, daily output, voltage and destination port. See reference projects from our Xiamen production base.
