15 m/min High-Speed PLC-Controlled Purlin Forming Machine with 5.5 kW Motor for Solar Bracket Roll Forming Machine Production

Manufactured by Howann, the 41x21 Solar Panel Mounting Bracket Roll Forming Machine is engineered to meet the demanding structural tolerances, high-volume schedules, and corrosion-resistance requirements of modern renewable energy infrastructure. Whether fabricating ground-mounted photovoltaic (PV) support frames, concrete flat-roof mounting rails, or electrical C-strut channels, this automated production line delivers consistent, high-speed profile forming with minimal manual intervention.

Constructed upon a heavy-gauge 300-450H welded steel structural base that absorbs torsional vibration during high-speed runs, the Howann profiling station integrates quenched and tempered 45# steel rollers, precision-hardened Cr12 high-grade alloy cutting blades, and a programmable PLC touch-screen control panel. Designed to handle standardized steel coils up to 400mm in feeding width, the machine achieves a continuous forming velocity of 8 to 15 meters per minute while maintaining strict profile squareness.

• Firsthand Field Expertise: Designed specifically for solar photovoltaic installation standards—delivering straight-angle strut channels with perfectly aligned pre-punched bolt holes for rapid field assembly.
• Rigid 300-450H Steel Base Chassis: Heavy structural steel framework provides exceptional torsional rigidity, preventing structural flexing under high-speed multi-stage forming loads.
• Precision Cr12 Hydraulic Shearing: Heat-treated Cr12 high-grade alloy tool steel cutting blades shear formed profiles instantly without burrs, distortion, or material waste.
• Intelligent PLC Touchscreen Interface: Programmable length counting, batch management, and inline flexible punching allow operators to switch between custom profile specifications seamlessly.
• Durable 45# Chrome-Plated Rollers: Precision-machined forming rolls undergo rigorous thermal quenching and chrome plating to ensure long-term wear resistance and protect zinc coatings on galvanized coils.

• Manual Uncoiling & Feeding: Coils are mounted on a 5-ton manual decoiler and fed smoothly into the adjustable round-wheel feeding table with minimal alignment error.
• Inline Rotary Punching: High-speed rotary punching devices create precise mounting holes before rolling, operating at maximum speeds of up to 80 m/min.
• Multi-Stage Roll Forming: Progressive forming stations gradually bend the steel strip through precise passes, transforming flat metal into rigid 41x21 C-strut channels.
• Automated Cutoff & Stacking: Rotary encoders track linear movement, signaling the PLC controller to trigger the hydraulic post-cutting mold for exact, burr-free lengths.

• Ground Photovoltaic Power Stations: Fabricating robust C-channels and mounting rails for large-scale utility solar farms.
• Concrete Flat-Roof PV Systems: Producing corrosion-resistant structural framing and ballast-compatible support brackets.
• Commercial Building Infrastructure: Manufacturing utility service channels, ceiling suspension grids, and drywall partition framing.

• Comprehensive Warranty Protection: Backed by a 2-year free warranty covering motors, gearboxes, and PLC logic modules, with replacement parts dispatched promptly.
• Transparent Quality Assurance: Every machine undergoes rigorous pre-shipment outgoing inspections, complete with testing reports and video verification.
• Export-Ready Packaging: Securely wrapped in waterproof and dustproof membranes, reinforced inside heavy export crates to withstand long-distance maritime transit.
