Steel Door Roll Forming Machine

A steel door roll forming machine builds one part of a door system, not the whole door. Frames, garage panels, shutter slats and guide tracks each need their own roll set, punch pattern and cutoff, and a door plant usually runs two or three of them side by side.

How the line works

Coil in, punched frame out

A steel door roll forming machine runs the same five steps as any light gauge line. The difference sits at the press: hinge holes, lock cutouts, strike plates and corner notches are punched before the profile is closed.

01

Decoiler

A 3 to 5 t mandrel carries galvanized coil. A coil car loads it without crane time.

02

Leveler and feeder

The leveler takes coil set out, then a servo feeder measures each frame or panel length.

03

Punching

Hinge holes, lock cutouts and notches are punched inline through a die set, one pattern per door size.

04

Roll forming

14 to 24 driven stations fold the profile. A frame needs more passes than a shutter slat of the same width.

05

Cutoff and stacking

A post cutter or flying shear cuts to length. Frames leave on a runout table, slats on a stacker.

Door components

Four parts one door plant rolls

Every quote for a steel door roll forming machine starts from the section drawing. The four below cover most of the door work we build for.

01 / Frame

Door frames

Single rabbet, double rabbet or return lip, folded from 0.8 to 2.0 mm galvanized. The frame is the heaviest section on the list.

02 / Panel

Garage door panels

Panels 0.4 to 0.8 mm thick with an embossed face, a hinged joint along each edge and punched handle and hinge points.

03 / Slat

Roller shutter slats

Interlocking slats, hollow or PU foamed, that roll up over the lintel. Slat pitch and curl radius decide the coil.

04 / Track

Guide tracks and bottom bars

Curved or straight track that guides the door, plus the bottom bar that closes the last slat.

Line configuration

What a door line is built to

Planning ranges for a steel door roll forming machine. The section drawing and the punch pattern are quoted first, then the coil width and the output target.

Coil width300 to 1,250 mm, set by the developed width of the section
Material thickness0.4 to 2.0 mm galvanized, 2.0 mm only on frame lines
Door size rangeFrame 700 to 1,200 mm wide, 2,000 to 2,400 mm high
Forming stations12 to 24, driven through gearbox and chain
Line speed8 to 15 m/min on frames, 12 to 20 m/min on slats and tracks
PunchingHydraulic press with one die set per door size, or servo punching for hinge and lock patterns
CutoffPost cutter or flying shear, tolerance plus or minus 0.5 mm
ControlPLC with HMI, inverter drive, length encoder and batch counter
Electrical supply380 V 50 Hz three phase, or 415 V, 440 V and 480 V for the destination
  • DecoilerManual 3 t as standard, hydraulic 5 t with a coil car on frame lines.
  • Forming frameWelded steel frame, 55 mm shafts on slats, 75 mm on frames up to 2.0 mm.
  • RollsCr12MoV hardened to 58 to 62 HRC, ground after heat treatment, chrome on request.
  • OptionsServo feeder, embossing rolls, automatic stacker and remote monitoring.
Cost drivers

Four things that move the price

Two quotes for the same frame can differ by a factor of two. These are the four choices that explain the gap, and the ones to settle before a steel door roll forming machine is ordered.

01

Punch pattern

A hydraulic press with a fixed die is the cheapest way to punch on a steel door roll forming machine. Servo punching with changeable hinge and lock patterns adds cost and removes setup time.

02

Section thickness

A 2.0 mm frame needs 75 mm shafts, a bigger frame and a heavier decoiler. Thickness drives steel weight through the whole machine.

03

Station count

A shutter slat forms in 14 stations, a return lip frame needs 22 or more. Every stand is a pair of rolls, a shaft and a motor.

04

Automation

A servo feeder, an automatic stacker and a packing table add 15 to 30 percent and take one or two operators off the line, which on a steel door roll forming machine is usually the whole payback case.

Build and test

Every line runs before it ships

A steel door roll forming machine is judged on its punch pattern as much as its profile. Each line is assembled, wired and run in our works with the customer's coil, then measured against the door schedule before packing.

  • Punch checkHinge, lock and notch positions are measured on the first ten pieces against the door schedule.
  • Roll settingEvery stand is set to the section drawing, then checked on a 3 m sample for width, squareness and lip height.
  • Trial runThe line runs at working speed. Cut length and hole position are logged and shipped with the machine.
  • PackingRolls are greased and wrapped, die sets boxed separately, and the line loads in one 40 ft container.

Coil for a steel door roll forming machine is galvanized to EN 10346 or ASTM A653, in 0.4 to 2.0 mm. On a frame, the zinc weight decides whether the section rusts at the weld-free corners.

Questions

Steel door roll forming machine FAQ

What buyers ask before a door line is quoted, answered in plain terms.

What is a steel door roll forming machine?

A steel door roll forming machine is a line that folds galvanized coil into one door component, such as a frame, a garage panel, a shutter slat or a guide track. It punches hinge holes, lock cutouts and notches inline, then cuts each piece to length. A complete door system needs two or three of these lines, not one.

What thickness can a steel door roll forming machine form?

Frames run 0.8 to 2.0 mm, garage panels 0.4 to 0.8 mm, shutter slats 0.4 to 0.8 mm and tracks 0.8 to 1.5 mm. A steel door roll forming machine built for 2.0 mm frames uses 75 mm shafts, while a slat line of the same width uses 55 mm.

How are hinge holes and lock cutouts made?

They are punched before the profile is closed, through a die set on a hydraulic press, or by a servo punch unit that moves between positions. One die set covers one door size, so a plant that sells six sizes keeps six sets, or pays for a servo punch that changes pattern from the screen.

Can one machine make frames and shutter slats?

No. The sections are different widths, thicknesses and pass counts, so a steel door roll forming machine is built for one section family. A combined plant buys a frame line and a slat line, and shares the decoiler and the control platform between them.

How fast does a door line run?

Frames run 8 to 15 m/min because of the punching cycle, slats and tracks 12 to 20 m/min. On a frame line the press, not the rolls, sets the pace, so a servo punch is what buys speed.

How much does a steel door roll forming machine cost?

A shutter slat or track line starts near USD 30,000. A garage door panel line with embossing lands at USD 45,000 to 70,000. A frame line with servo feeding and servo punching runs USD 60,000 to 110,000, and a full PU foamed slat line with a foaming unit goes above that.

What is the lead time and how does the line ship?

Build time is 30 to 55 days after the drawing and the deposit. A slat or track line loads into one 40 ft container, a frame line with a long runout table needs a 40 ft high cube. Sea freight adds 20 to 40 days depending on the port.
