Metal Sheet Roll Forming Machine
A metal sheet roll forming machine turns coated steel or aluminium coil into roof and wall panels in one pass. Coil goes in at one end, a finished panel is cut and stacked at the other, with rib height and cover width set from the drawing.
Building lines since 2005. 500+ machines in 50+ countries. ISO 9001 certified, CE compliant.
Panel firstRib profile, steel grade and cover width decide the rolls before any coil is cut.

How the line works
Coil in, stacked panel out
Every metal sheet roll forming machine runs the same five steps. What changes is coil width, station count and how much runs without an operator.
01
Decoiler
Manual or hydraulic mandrel takes 5 to 10 t coils. A coil car loads without crane time.
02
Leveler and feeder
The leveler removes coil set, then a servo feeder sets the length of each panel.
03
Punching
Fastener holes and end notches are punched inline, with scrap dropping clear.
04
Roll forming
12 to 26 driven stations form the ribs in steps. Station count follows rib height and thickness.
05
Cutoff and stacking
A shear or flying saw cuts to length. Panels leave on a runout table or an automatic stacker.
Panel types
Four panel families these lines run
The panel drawing starts every quote for a metal sheet roll forming machine. Cover width, rib height and fixing detail decide the roll set.
01 / Trapezoidal
IBR and trapezoidal sheet
Trapezoid ribs 12 to 32 mm high. The default roof and wall panel on industrial buildings, at 686 to 1,000 mm cover.
02 / Corrugated
Corrugated sheet
A round wave with no sharp corner. Cheap to run, common in Africa and South America, at 762, 840 or 900 mm cover.
03 / Standing seam
Standing seam and Klip-Lok
Concealed fixing under a raised seam that is crimped or snapped shut. Used where a low pitch has to stay watertight.
04 / Tile
Tile and shingle profiles
Step tile, glazed tile and Monterey press a tile look into steel. The roof reads as clay from the street at a fraction of the weight.
Machine range
Six metal sheet roll forming machines
Each page covers one panel family with its drawing, station count and output. All six share one frame, drive and control platform.
01 / IBR
IBR Sheet Roll Forming Machine
Inverted box rib at 686 mm cover. The default roof and wall sheet for steel buildings in Africa and the Middle East.
View IBR line →
02 / Corrugated
Corrugated Sheet Roll Forming Machine
Round wave at 762, 840 or 900 mm cover. Often run as a double layer mill with a trapezoidal profile above.
View corrugated line →
03 / Standing seam
Klip-Lok Roof Sheet Machine
Concealed clip fixing at 406 mm cover. No fastener through the sheet, so the roof stays tight down to 2 degrees.
View Klip-Lok line →
04 / Wall panel
Metal Wall Panel Machine
Shallow rib cladding with a flat pan between ribs. Panels run 0.4 to 0.8 mm and stack flat for transport.
View wall panel line →
05 / Tile
Glazed Tile Roll Forming Machine
Pressed tile relief on 0.3 to 0.6 mm sheet. Villas, schools and small commercial roofs that have to read as tile.
View glazed tile line →
06 / Box profile
Box Profile Roofing Machine
Square box ribs with a wide flat pan, the common UK and export profile. Long runs stay straight at a shallow rib.
View box profile line →Two more layouts sit outside this list. A double layer roll forming machine runs two profiles on one frame, and a Bemo sheet line covers the deep trapezoidal profiles of large span roofs.
Line configuration
What a metal sheet line is built to
Planning ranges for a metal sheet roll forming machine. The line is quoted from the panel drawing, then the steel grade and the output target.
| Coil width | 1,000, 1,220 or 1,250 mm as standard, up to 1,500 mm on request |
|---|---|
| Material thickness | 0.3 to 1.2 mm, 1.5 mm on a reinforced mill |
| Cover width | 686 to 1,000 mm, fixed by the profile drawing |
| Rib height | 12 to 32 mm on trapezoidal, 3 to 6 mm on corrugated |
| Forming stations | 12 to 26, driven through gearbox and chain |

- OptionsServo feeder, automatic stacker, packing table and remote monitoring.
Cost drivers
Four things that move the price
Two quotes for the same panel can differ by a factor of three. These four choices explain the gap, and they are the ones to settle before a metal sheet roll forming machine is ordered.
01
Station count
Every extra station adds a stand, a pair of rolls and a motor. A 14 station mill costs far less than a 24 station tile mill.
02
Cutoff type
A hydraulic shear is the cheapest cut. A flying shear adds cost and lets the line run two to three times faster.
03
Coil width
Wider panels need a wider frame, longer shafts and a bigger decoiler. A 1,250 mm line is a heavier machine, not a stretched 1,000 mm one.
04
Automation
Servo feeding, an automatic stacker and a packing table add 15 to 30 percent and take two operators off the line.
Applications
Where these panels end up
Panel choice follows the building, not the machine. These four jobs cover most of the orders we quote, and each sets the rib and the coating.
01 / Industrial roofing
Factories, warehouses and sheds
Trapezoidal and IBR panels over steel purlins, usually 0.5 mm galvanized with a colour coat on the weather face.
Roof and wall panels for steel buildings →
02 / Wall cladding
Facades and insulated walls
Shallow rib panels clip over the girt line and hide the fixing. The same line runs the liner panel inside.
Wall cladding roll forming lines →
03 / Agriculture
Farm, poultry and storage sheds
Wide low roofs with a light load. Panels are cut to the full slope, so the shed closes without an end lap.
Agricultural roll forming applications →
04 / Cold chain
Cold rooms and food plants
Cold store walls use a shallow box panel as the outer skin with foam behind it. Flat pans matter more than rib height.
Box profile line for cold storage →Panels are rolled to EN 10169 or ASTM A792 coating standards, and lines for the EU arrive with CE documentation under the EU CE marking rules. For the UK the same line is documented to UKCA through the GOV.UK UKCA guidance.
Build and test
Every line runs before it ships
A metal sheet roll forming machine is only as good as its first coil. Each line is assembled, wired and run in our works with the customer's material, then measured against the drawing before packing.
- Roll settingEvery stand is set to the drawing, then checked on a 3 m sample for rib height, pitch and cover width.
- Trial runThe line runs the full coil width at working speed. Cut length, squareness and hole position are logged.
- Electrical checkPanel wiring and inverters are tested at the destination voltage.
- PackingRolls are greased and wrapped, shafts braced, and the line loads in one 40 ft container.
Coil for a metal sheet roll forming machine is galvanized to EN 10346 or ASTM A653 and prepainted to EN 10169, in 0.3 to 1.2 mm. On a thin panel, thickness tolerance matters more than coating weight.
Questions
Metal sheet roll forming machine FAQ
What buyers ask before a line is quoted, answered in plain terms.
What is a metal sheet roll forming machine?
A metal sheet roll forming machine is a continuous line that bends coated steel or aluminium coil into roof and wall panels. Coil is decoiled, leveled and fed through 12 to 26 driven stations, then cut to length by a shear or saw. Holes and notches are punched inline on the same pass.
What thickness can a metal sheet roll forming machine form?
Standard lines run 0.3 to 1.2 mm. Roof panels sit at 0.4 to 0.8 mm, wall panels 0.4 to 0.7 mm and tile profiles 0.3 to 0.6 mm. A metal sheet roll forming machine with 65 mm shafts reaches 1.5 mm, at a higher cost and a lower speed.
How fast does a metal sheet roll forming machine run?
10 to 15 m/min with a hydraulic shear and 25 to 35 m/min with a flying shear. Panel length sets the real limit, because a flying saw needs a run-up and run-down for every cut.
How many stations does a metal sheet roll forming machine need?
A metal sheet roll forming machine needs 12 to 16 stations for shallow corrugated or wall panels, 18 to 20 for IBR and Klip-Lok, and 20 to 26 for a tile profile. Too few stations leaves spring back in the rib, and the panel will not nest on the roof.
Can one metal sheet roll forming machine run IBR and corrugated?
Yes, two ways. A double layer machine puts one profile on the top frame and the other underneath, so the line switches by changing the feed direction. A single layer machine needs a second set of roll packs, and changeover takes two to four hours.
How much does a metal sheet roll forming machine cost?
A metal sheet roll forming machine for one corrugated or wall panel profile starts near USD 25,000. An IBR or Klip-Lok line with a hydraulic shear lands at USD 35,000 to 60,000. A tile line with 24 stations, servo feeding and a stacker runs USD 70,000 to 120,000.
How long is the lead time and how does the line ship?
Build time is 30 to 60 days after the drawing and deposit. A single profile line loads into one 40 ft container, a double layer line into a 40 ft high cube. Sea freight adds 20 to 40 days.
