M Profile Steel Roll Forming Machine – Automatic M Section Cold Forming Line for Structural Steel

The M profile steel roll forming machine​ is a continuous cold-bending production line engineered to manufacture M-shaped (M-section) steel profiles from galvanized steel, cold-rolled steel, carbon steel or high-strength coil. With progressive multi-station roller tooling, the line forms flat strip into a symmetrical M cross-section with stable geometry, high torsional resistance and repeatable tolerances—ideal for steel structure plants, purlin distributors, mining support manufacturers and prefab building exporters.

Unlike a generic purlin machine, an M section forming machine​ is tuned for the deeper flange and double-peak geometry of M steel, often integrated with punching, servo feeding and flying cutting so the finished sections come off the line ready for bolting or welding.

Why Buyers Choose an M-Shaped Steel Roll Former

Profile accuracy​ – GCr15/Cr12MoV hardened rollers, HRC 58–62, chrome plated; cross-section tolerance ±0.5 mm, length tolerance ±1 mm.

 

Flexible material range​ – 1.5–3.5 mm thickness (light gauge to heavy M purlin), coil width 180–400 mm, yield strength 235–550 MPa.

 

Automatic workflow​ – hydraulic decoiler → leveling → guide feeding → roll forming → hydraulic/servo punching → flying cut → run-out table, all controlled by Siemens/Delta/Mitsubishi PLC + HMI.

 

Fast changeover​ – single-profile M machine or quick-change C/Z/U/M combined line; mold reset within 10–30 min on multi-profile models.

 

Export-ready build​ – 380V/50Hz/3Ph standard, 415V/480V/60Hz customizable, IP54 cabinet, CE/ISO optional, English/HMI interface, spare parts kit.

Where M Profile Steel Is Used

M-section steel produced by this cold roll forming line is widely specified in:

Steel structure buildings​ – workshop purlins, roof bracket channels, wall girt supports

 

Mining & tunnel support​ – M-shaped steel arch segments, rock-bolt backing strips

 

Industrial racking & mezzanine frames​ – high-load horizontal braces

 

Prefab & modular construction​ – ceiling keel, partition top/bottom track

 

Infrastructure​ – bridge auxiliary brackets, utility gallery supports

 

If your project needs C, Z, U and M in one plant, we can configure a combined CZU+M purlin roll forming machine​ with quick-change spacers to reduce capital duplication.

 

How the M Steel Forming Process Works

Hydraulic decoiler holds 5–10 t coil, auto-centering and tension control.

 

Leveling unit flattens strip and removes coil curl before forming.

 

Servo feeder + guide locks strip position to avoid twist.

 

Multi-station roll forming bends the M shape gradually—no cracking, no springback beyond tolerance.

 

Inline punching (optional) stamps bolt holes, slots or embossing synchronized with line speed.

 

Flying shear cuts to set length without stopping the line.

 

Run-out roller table / stacker collects finished M profiles for bundling.

FAQ – M Profile Steel Roll Forming Machine

Q: Is this the same as an M purlin machine?​

A: Yes. In many markets “M purlin” and “M section steel” refer to the same double-peak cold-formed profile; we build both light purlin and heavy support versions.

Q: Can one machine make different M sizes?​

A: For a single-profile machine, width/thickness change requires roller set swap. For variable-width demand, choose an adjustable M-section former with shim/spacer adjustment.

Q: What is the delivery time?​

A: Standard line 35–50 days after deposit and profile confirmation; customized punching or 480V version adds 7–10 days.

Q: Do you supply installation abroad?​

A: Yes—engineer on-site commissioning, operator training, English manual, lifetime remote support.
