Product Description
Howann High-Efficiency Double Layer Roll Forming Machine | Dual Profile Roofing Sheet Production Line
Engineered by Howann, this versatile Double Layer Roll Forming Machine offers a cost-effective 2-in-1 manufacturing solution for producing two popular roofing profiles—such as IBR trapezoidal panels, corrugated sheets, or glazed roof tiles—on a single machine frame. Ideal for metal roofing manufacturers with limited floor space, this dual-level production line handles pre-painted steel (PPGI), galvanized iron (GI), and aluminum coils from 0.2 mm to 1.0 mm in thickness.
Built upon a heavy-duty 350H H-beam structural base, the Howann double-deck system isolates upper and lower forming levels with independent clutch drives, ensuring smooth operation without gear interference. Guided by an intelligent industrial PLC control panel, operators can easily switch between profile modes, program target sheet lengths, and manage production batches with high precision.

Core Features & Engineering Highlights
- Space-Saving 2-in-1 Architecture: Integrates two independent profile forming passes vertically on one chassis, reducing plant space requirements by 50%.
- Independent Clutch Drive Switch: Simple clutch engagement allows operators to alternate power between top and bottom levels safely and efficiently.
- Rigid 350H H-Beam Base Frame: Reinforced heavy-gauge steel chassis eliminates mechanical flexing during continuous 15 m/min production runs.
- Quenched 45# Steel Shafts: Solid roller shafts undergo rigorous thermal quenching and tempering to prevent rotational deformation under heavy load.
- Programmable Touchscreen PLC System: User-friendly interface supports multilingual operation, batch counting, and precision optical length measuring.
Machine Workflow & Operation
- Coil Loading & Alignment: Raw steel coil feeds smoothly from the uncoiler through precision entry guide rollers.
- Selective Level Roller Forming: The selected upper or lower deck shapes flat strip step-by-step into uniform trapezoidal or corrugated profiles.
- Automated Hydraulic Shear Cut-off: High-precision encoder signals the Cr12 post-cut blade to sever finished panels neatly to preset program lengths.
- Finished Sheet Discharge: Formed panels exit cleanly onto support run-out tables ready for stacking and packaging.
Primary Industrial Applications
- Dual-Profile Commercial Roofing: Flexible production of IBR trapezoidal roofing and corrugated cladding sheets for commercial buildings.
- Agricultural Facilities: Weather-resistant galvanized roofing tiles for farm storage, barns, and livestock shelters.
- Residential Construction: Decorative color-coated PPGI roof panels for housing projects, villas, and carports.
- Modular & Temporary Buildings: Roof and wall panels for container houses, site offices, and temporary shelters.
Customization & Service Options
- Custom Profile Combination: Choose your preferred top and bottom profile combinations (e.g., IBR + Corrugated, Glazed Tile + Trapezoidal).
- Uncoiler Options: 5-ton or 7-ton manual or hydraulic expansion uncoilers with optional coil loading cars.
- Custom Electrical Setup: Configurable for 220V, 380V, 415V, or 480V (3-Phase, 50/60 Hz).
Frequently Asked Questions (FAQ)
Q1: Can both upper and lower forming decks operate at the same time?
To ensure maximum power efficiency and operator safety, the machine utilizes a clutch system to run one deck level at a time, allowing quick switching between the two profiles.
Q2: What profile combinations can be built on this Howann double layer machine?
Popular profile combinations include IBR trapezoidal with corrugated, glazed roof tile with IBR, or two different sizes of trapezoidal wall cladding sheets.
Q3: What after-sales service and warranty are included with Howann machinery?
Howann provides a 1-year factory warranty, CE/ISO quality certifications, video outgoing inspections, machinery test reports, and free replacement spare parts during the warranty period.
