8–15 m/min Dual-Profile Double Layer Roof Sheet Roll Forming Machine with 400H Heavy-Duty Hydraulic Station
Product Details
8–15 m/min Double Layer Roof Sheet Roll Forming Machine
,400H Heavy-Duty Dual-Profile Roll Forming Machine
,Dual-Profile Double Deck Roll Forming Machine
Manufactured by Howann, the Double Layer Roof Sheet Roll Forming Machine is engineered to meet the demanding workload, high-volume production schedules, and strict space-saving requirements of modern architectural metal roofing fabricators. By stacking two distinct profile decks vertically onto a single 400H heavy-duty structural frame, this dual-purpose manufacturing station cuts required workshop floor space and equipment investment costs in half while enabling seamless switching between elegant Spanish glazed roof tiles and heavy-duty industrial trapezoidal panels.
Constructed upon a substantial 4,000 kg welded steel structural base that absorbs harmonic vibrations during high-speed rolling passes, the Howann profiling station integrates quenched and tempered 45# forged steel rollers (precision-machined to protect pre-painted coil coatings), precision-hardened Cr12 mold steel cutting blades, and an advanced programmable PLC touch-screen control system to deliver flawless, burr-free roofing sheets ready for immediate jobsite stacking and installation.

- Firsthand Roofing Contractor Experience: Designed based on direct feedback from global metal fabricators—eliminating the need for two separate factory lines by combining glazed tile and trapezoidal profiling onto one compact vertical chassis.
- Deep Engineering Expertise: Quenched and tempered 45# forged rollers undergo precision CNC milling to ensure smooth metal forming without scratching or stripping the protective zinc and paint layers on PPGI coils.
- Industry Authoritativeness: Manufactured by Zhengzhou Howann Machinery Inc. in a certified 3,000-square-meter production facility, adhering strictly to CE safety directives and ISO9001 quality management protocols.
- Uncompromised Trustworthiness: Backed by a robust 3-year warranty, transparent tiered wholesale pricing, and mandatory pre-shipment factory test runs with video verification reports.
- Rigid 400H Steel Base Construction: Heavy 4,000 kg structural chassis architecture eliminates structural flexing under high torsional loads, ensuring consistent profile straightness and lock-seam symmetry.
- Coil Loading & Uncoiling: PPGI or galvanized steel coils are mounted on the manual decoiler and fed smoothly into the entry guide table with minimal lateral drift.
- Upper & Lower Progressive Forming: Calibrated roller stations on both upper and lower decks progressively press the steel sheet through multi-stage passes to form either glazed tiles or trapezoidal ribs.
- Automated Length Measurement: Rotary encoders track linear travel distance in real time, signaling the PLC controller when the exact programmed panel length is achieved.
- Hydraulic Post-Cutting & Stacking: The Cr12 alloy blade shears the formed profile instantly with clean edges, eliminating secondary trimming requirements before final packaging.
- Commercial & Residential Roofing: Fabricating aesthetic Spanish roof tiles and rugged trapezoidal panels for villas, warehouses, and commercial complexes.
- Regional Building Material Supply Yards: Centralized manufacturing hubs supplying versatile, custom-cut metal roofing solutions directly to local contractors.
- Steel Structure Construction: Producing durable, weather-resistant wall and roof cladding sheets for portal frame industrial buildings.
As highlighted in professional equipment specifications for the Double Layer Roof Sheet Roll Forming Machine, stacking two profiles vertically cuts required factory floor space in half, lowers initial capital expenditure, and allows operators to switch between glazed tile and trapezoidal production without retooling.
The system is specifically engineered to handle color-coated PPGI, Galvalume, and galvanized steel coils ranging from 0.2 mm to 0.6 mm in rolling thickness.
Howann provides complete compliance paperwork including CE certificates, ISO9001 quality audit reports, electrical wiring schematics, and comprehensive English operation manuals.
