20 m/min High-Speed Solar Strut Channel Roll Forming Machine with 5.5 kW PLC-Controlled Photovoltaic Support Channel Production Line for 1.2-1.5 mm Steel

Manufactured by Howann, the Solar Strut Channel Roll Forming Machine is engineered to meet the demanding structural tolerances, high-volume production schedules, and extreme load-bearing requirements of modern photovoltaic (PV) solar farms and commercial energy infrastructure. Moving beyond basic framing tools, this heavy-duty automated production line combines inline rotary punching, multi-stage cold roll forming, and automated hydraulic cut-off to deliver straight, rigid C-channels and unistrut profiles ready for immediate field installation.

Constructed upon a heavy-gauge 350H welded steel structural base weighing a substantial 4,500 kg, the Howann profiling station absorbs resonant vibrations during high-speed rolling passes. It integrates quenched and tempered 45# forged steel rollers (hard-chrome plated for superior surface preservation), precision-hardened Cr12 mold steel cutting blades, and an advanced programmable PLC touch-screen control system to deliver flawless, high-integrity photovoltaic support profiles.

• Firsthand Renewable Energy Experience: Designed based on direct feedback from solar farm developers—prioritizing precise hole-pitch alignment and wind-resistant strut geometries to streamline outdoor bolting and assembly.
• Deep Engineering Expertise: Hard-chrome plated 45# forged rollers prevent zinc-coating scraping on pre-galvanized steel coils, protecting the corrosion-resistant barrier essential for decades of outdoor weathering.
• Industry Authoritativeness: Manufactured by Zhengzhou Howann Machinery Inc. in a certified 9,700-square-meter production facility, adhering strictly to CE safety directives and ISO9001 quality management protocols.
• Uncompromised Trustworthiness: Backed by a solid 1-year warranty, transparent tiered pricing structures, and mandatory pre-shipment factory test runs with video verification reports.
• Rigid 350H Steel Base Construction: Heavy 4,500 kg chassis architecture eliminates structural flexing under high torsional loads, ensuring consistent profile straightness and slot symmetry.

• Coil Loading & Guiding: Raw structural steel strips are fed smoothly from the uncoiler through an adjustable alignment table into the punching module.
• Inline High-Speed Rotary Punching: Integrated pneumatic punching dies create exact mounting and fastening holes at speeds up to 80 meters per minute prior to rolling.
• Progressive Cold Roll Forming: Multiple forming stands gradually press the steel strip through calibrated passes, transforming flat metal into rigid solar strut channels.
• Hydraulic Post-Cutting & Stacking: Rotary encoders signal the PLC controller to trigger the Cr12 hydraulic shear, cutting finished profiles cleanly without burrs or tool changes.

• Ground-Mounted Photovoltaic Farms: Fabricating heavy-duty C-channels and support framing for utility-scale solar arrays.
• Commercial Rooftop Solar Arrays: Producing lightweight, high-strength structural mounting rails compatible with flat-roof ballasted systems.
• Electrical & Mechanical Service Supports: Manufacturing utility service channels, cable tray support brackets, and ceiling suspension grids.
