Howann High-Precision R Panel Roll Forming Machine with 15 m/min Speed for 0.3 – 0.8 mm Sheets and 5.5 kW Motor

Manufactured by Howann, this heavy-duty R Panel Roll Forming Machine offers an automated, high-volume production solution for fabricating standard R-Panel and PBR-Panel 5-rib trapezoidal steel roof sheets and exterior wall siding. Engineered to form color-coated steel (PPGI), galvanized steel (GI), and galvalume sheets from 0.3 mm to 0.8 mm in thickness, this equipment integrates precision decoiling, guided roller forming, automated hydraulic shearing, and output panel stacking into one seamless line.

The Howann 5-rib sheet line is built on a heavy-gauge welded steel chassis to eliminate machine frame flex during high-speed production runs up to 15 m/min. Driven by a powerful 5.5 kW main drive motor and regulated by an interactive touchscreen PLC controller, operators can easily store job orders, set sheet batch sizes, and execute exact length cutting with zero panel distortion.

• High-Rib Structural Rigidity: Produces deep 5-rib R/PBR profiles engineered for high snow load capacity, excellent water shedding, and structural span strength.
• Heavy-Duty 5.5 kW Power Drive: Delivers smooth, uninterrupted torque through precision gearboxes to form high-tensile steel coils up to 15 m/min.
• Hard Chrome-Plated Rollers: Precision-milled 45# forged steel forming rollers protect pre-painted coil coatings from scuffing or paint peeling.
• Cr12 Hydraulic Post-Shearing Cutter: High-hardness alloy steel cutter ensures clean, burr-free end cuts without deforming rib geometries.
• Programmable PLC Command System: Multilingual touchscreen controller tracks linear footage, controls optical encoder accuracy, and manages job batch queues.

• Coil Uncoiling & Entry Guidance: Heavy steel coil feeds smoothly into precision adjustable side-guiding rollers to ensure exact sheet alignment.
• Progressive 5-Rib Roll Forming: Multi-pass roller stations gradually form flat sheet metal into uniform R/PBR trapezoidal ribs without material stress cracking.
• PLC Optical Length Measurement: High-resolution encoder monitors feed distance, triggering hydraulic cutting at programmed dimensions.
• Automated Cut-Off & Stacking: Synchronized shear blade severs completed R-panels cleanly onto discharge collection racks.

• Commercial & Industrial Roofs: High-tensile 5-rib roof panels for logistics hubs, factories, commercial complexes, and clear-span warehouses.
• Steel Building Wall Siding: Durable exterior wall cladding panels for pre-engineered metal buildings (PEMB) and aircraft hangars.
• Agricultural Sheds & Barns: Corrosion-resistant galvanized R-panel roofing for grain storage, livestock barns, and farm equipment housing.
• Self-Storage & Residential Facilities: Profile panels for mini-storage facilities, workshop roofs, and residential carports.

• Custom Profile Tooling: Roller dies customized to your specific regional R-panel or PBR-panel CAD blueprints.
• Uncoiler Options: Choice of 5-ton manual or hydraulic auto-expansion decoilers with optional loading cars.
• Electrical Supply Grid: Tailored for 220V, 380V, 415V, or 480V (3-Phase, 50/60 Hz).
