Corrugated steel panel roll forming machines are used to produce corrugated steel panels for various applications such as roofing, wall cladding, partitions, silos, sheds, and more. These machines form the corrugated shape and required profile on metal coil strips through a series of rollers. The ribbed corrugated shape provides excellent structural strength and rigidity to the steel panels.
Corrugated steel panels provide durability, customizability, cost-effectiveness, weather-resistance, fire resistance, acoustic insulation, and quick installation. They are utilized extensively in industrial, commercial, infrastructural, and residential building construction for wall cladding, roofing, interior partition, ceiling, flooring, and decking applications.
The main components of corrugated steel panel roll forming machines include an uncoiler or de-coiler, feeding mechanism, forming and cutting section with roller dies, hydraulic system, PLC control system, and the exit table. Modern corrugated panel forming lines are fully automated with high production speeds and superior precision.
This guide covers the types, working principles, components, specifications, cost factors, suppliers, applications, advantages and limitations of corrugated steel panel roll forming equipment. It aims to help machinery buyers and engineers select optimal roll former configurations and suppliers for their production needs and budget.

Working Principle of Corrugated Panel Roll Forming
Corrugated steel panel production through roll forming involves unwinding a flat metal sheet or coil strip, passing it through a series of roller dies to bend it into the ribbed corrugated shape, and cutting the panels to required length.
The working stages are:
- Decoiling – The plain galvanized steel coil is loaded on an uncoiler which unwinds and feeds the strip through the infeed guides.
- Feeding – The sheet is gripped by caterpillar feed rollers which pull the strip through the machine at a constant speed.
- Pre-forming – The strip passes through a straightening machine and initial pre-forming rollers to start bend formation.
- Forming – In the main roll forming section, the sheet passes through a series of roller dies which bend the strip incrementally to form the corrugated profile.
- Cutting – After achieving the final corrugated shape, the formed strip moves to the cutoff press which shears the panels at desired lengths.
- Counting – Panel counting sensors after the cutoff to count cut panels stacked on the exit table.
- Stacking – Formed panels are collected on the exit conveyor table for manual or automated stacking.

Design Factors for Corrugated Panel Roll Formers
- Profile shape – Sinusoidal, rounded, angular, box/dovetail type ribs
- Number of corrugations per meter/inch
- Rib height – Higher rib provides greater strength
- Metal thickness – Thicker coils allow deeper profiles
- Sheet width – Wider coils need higher forming power
- Cut length – Longer panels may need support rollers
- Type of steel – Galvanized, prepainted, stainless, aluminum
- End product application – Roofing, walls, flooring, silos etc.
The machine has to be designed specifically based on these parameters to achieve the required corrugated profile dimensions accurately.
Installation and Operation of Corrugated Steel Panel Roll Forming Equipment
|Level concrete or steel foundation with space for unwinding coils and collecting panels
|Ensure proper infeed-forming-cutoff-outfeed flow path orientation
|Connect electric supply and control cables to control panel
|Test with dummy coils, set speeds, profiles and tolerances
|Use overhead crane or forklift to load coils on decoiler
|Input control parameters like speed, length, counts etc via PLC
|Corrugated Panel Production

Q: What sheet metal thickness is suitable for corrugated panels?
A: 0.4 mm to 1 mm thick galvanized steel coils are commonly used. Up to 1.5mm sheets can be corrugated for extra strength. For aluminum, 0.7 mm to 1 mm sheets are ideal.
Q: What is the difference between box rib and trapezoidal corrugated profiles?
A: Box rib profiles have four flat sides for each rib giving higher bending strength. Trapezoidal profiles have inclined rib side walls which provide higher shear strength.
Q: How are prepainted color coated sheets formed into corrugated panels?
A: Additional UV paint curing stations are incorporated in the roll former above the final forming stands for the color coating.
Q: What are the maintenance best practices for corrugated panel machines?
A: Regular lubrication of rollers, inspection of sensors and hydraulics, monitoring belt tensions and machine alignment ensures optimal performance.
Q: How can production speed be increased in roll forming lines?
A: Use higher power AC vector drives, minimize roller friction, reduce number of passes, use high strength and thin sheets to increase corrugated panel production speed.
Q: How to reduce noise levels in corrugated roll forming machines?
A: Use noise damping materials on covers, reduce panel vibration, use resilent rubber rollers, minimize friction, and lubricate moving parts regularly.
