The Galvanized Corrugated Roofing Sheet Roll Forming Machine 380V is a fully automatic cold-roll forming production line engineered for continuous, high-precision manufacturing of corrugated metal roofing and wall panels. Designed for long-term industrial use, the machine processes galvanized steel (GI), pre-painted galvanized steel (PPGI), galvalume (GL/PPGL) and aluminum coils into consistent sinusoidal or customized corrugated profiles with excellent surface quality and dimensional accuracy.
Built on a heavy-duty 350H or 360H steel frame with high-grade 45# steel rollers (hard-chrome plated) and solid shafts (Φ70–80 mm), the line delivers stable operation, low maintenance and service life exceeding 10–15 years under normal production conditions. The standard 380V/50Hz/3-phase electrical system (customizable to local voltage) combined with Delta or Siemens PLC + touch-screen HMI ensures precise length control, automatic counting and easy parameter adjustment.

Working Process
- Manual / Hydraulic decoiler → coil loading
- Feeding & guiding device (adjustable width)
- Progressive roll forming through multiple stations
- Hydraulic length-set cutting
- Output table / run-out support
The progressive forming design minimizes material stress and spring-back, delivering uniform wave height, pitch and surface finish.
Core Advantages – Reliable Quality & Technical Solutions
- Precision & Consistency: Closed-loop PLC control and high-precision rollers keep length tolerance within ±1–2 mm and profile accuracy within 0.5 mm.
- Material Flexibility: Processes a wide range of coated steels without surface damage; ideal for both standard and high-strength (up to 550 MPa) coils.
- High Efficiency: Continuous production at 8–15 m/min with automatic cutting and counting reduces labor and increases daily output.
- Durable Construction: Heavy H-beam frame, chrome-plated rollers and quality bearings ensure stable long-term operation and low maintenance cost.
- Full Customization: Wave height, pitch, coverage width and profile drawings can be tailored to local market standards (e.g., 762, 836, 850, 1000 series).
- Safety & Compliance: CE-ready design, emergency stops, safety covers and overload protection.
- Long-Term Support: 1–2 year warranty, lifetime technical assistance, spare-parts supply and optional overseas installation & training.
Main Application Scenarios & Selection Guidance
This 380V Galvanized Corrugated Roofing Sheet Roll Forming Machine is designed for manufacturers supplying:
- Industrial warehouses and factory roofs
- Agricultural buildings and livestock shelters
- Commercial and residential metal cladding
- Temporary construction and modular buildings
Selection recommendations:
- Choose 0.4–0.5 mm thickness + 18 mm wave height for standard residential and light industrial roofs (optimal balance of weight and load capacity).
- Select 0.6–0.8 mm + higher wave height (22–25 mm) when wind or snow loads exceed local code requirements.
- For pre-painted coils, insist on polished chrome rollers to avoid coating damage.
- High-volume plants (>25 tons/day) should specify optional gear-drive and flying-cut systems to reach 20–30 m/min.
Risk note: Using coils outside the stated thickness or yield-strength range can cause roller overload, profile distortion or premature bearing failure. Always confirm coil certificate data before production.
Certification & Applicable Standards
Machines are supplied with CE marking and ISO 9001 quality system compliance. Formed sheets typically meet the dimensional and coating requirements of ASTM A653, EN 10346 and equivalent regional standards for continuous hot-dip galvanized steel. Third-party inspection (SGS / BV) is available on request. Electrical systems conform to IEC industrial safety practices for 380V three-phase equipment.
Installation & Operating Precautions
- Foundation must be level within 2 mm/m; anchor bolts should be properly tensioned after initial running-in.
- Fill hydraulic oil to 2/3 level before first start; use recommended ISO VG 46 hydraulic oil.
- Perform daily lubrication of chains, bearings and sliding surfaces.
- Never exceed rated thickness or yield strength; monitor motor current during first production runs.
- Keep safety guards in place; only trained operators should adjust roller gaps or change tooling.
- For long-term storage or relocation, protect chrome surfaces against corrosion.
Frequently Asked Technical Questions (FAQ)
What voltage and power supply does the machine require?
Standard configuration is 380V / 50 Hz / 3-phase. Full customization (220–480 V, 50/60 Hz) is available to match local grid standards.
What is the typical production capacity?
At 10–12 m/min average speed with 6 m sheets, output reaches approximately 20–30 tons per 8-hour shift depending on coil changeover frequency.
Can the machine produce different wave profiles?
Yes. Wave height, pitch and number of corrugations are customized according to customer CAD drawings. Tooling change is straightforward on multi-station designs.
What is the expected service life of the rollers?
With correct material thickness, proper lubrication and chrome-plated 45# rollers, service life typically exceeds 10 years under continuous industrial use.
Is on-site installation and training provided?
Yes. Experienced technicians can be dispatched for installation, commissioning and operator training. Remote PLC support is also available.
