A corrugated sheet is a metal panel with a repeating wave‑like (sinusoidal) profile. It is the most basic and widely used roofing and cladding material in the world – from rural farm buildings in Africa to industrial sheds in Southeast Asia and residential roofs in South America.
The wave pattern gives the sheet strength and rigidity while keeping material thickness low, making it an economical choice for large roof areas. Corrugated sheets can be made from galvanized steel, PPGI (pre‑painted), aluminum, or stainless steel.
A Corrugated Roll Forming Machine is a industrial machine that continuously produces corrugated metal sheets – the classic wavy (sinusoidal) roofing and cladding panels used worldwide. It is the simplest, most affordable, and most popular type of roll forming machine for basic metal roofing.
Corrugated sheets are characterized by a repeating wave pattern with a standard pitch (distance between wave peaks) of 75mm (common in Europe, Asia, Africa) or 100mm (common in Australia, Latin America). The wave height is typically 12–18mm.

18‑gauge / 20‑gauge profiles for heavier applications
A streamlined forming system with fewer moving components makes the machine easy to maintain and reliable for continuous production, helping reduce maintenance requirements and downtime.
The forming rollers are manufactured from 45# forged steel with hard chrome plating and CNC-machined for accurate profiling. The precision roller design helps maintain consistent panel shape and dimensions throughout the coil length.
The machine features a PLC touchscreen control system for easy operation and production management. An optional manual counter is also available to meet different production requirements.
The hydraulic cutting system uses heavy-duty cutting blades to produce clean, accurate cuts with minimal burrs. Properly cut panels can be stacked neatly and handled easily.
The electrical system can be customized to meet local power requirements, including 220V / 380V / 415V and 50Hz / 60Hz configurations.
The compact machine layout requires less workshop space, with machine lengths available from approximately 5 m, depending on the machine configuration. Optional casters can be provided for easier repositioning.
The streamlined machine design helps reduce initial equipment investment, maintenance requirements, and operating costs, making it suitable for both new and established metal roofing production lines.
As a direct roll forming machine manufacturer, we provide readily available spare parts, professional technical assistance, and lifetime technical support to help maintain reliable machine operation.
Standard: 75mm and 100mm. We can also make 60mm, 80mm, 125mm – just send your drawing or sample.
Yes – we design rollers based on your required effective coverage (e.g., 6 waves, 8 waves, 12 waves).
0.2mm to 0.8mm standard. Up to 1.0mm available for heavy‑duty version.
No. The machine is very simple. One person can learn in 1–2 hours. PLC version makes it even easier.
