Howann Dual-Profile Glazed Tile & Trapezoidal Cr 12 Double Layer Roll Forming Machine | 2-in-1 Roof Sheet Production Line
Engineered by Howann, this high-efficiency Double Layer Glazed Tile & Trapezoidal Roll Forming Machine provides a versatile, space-saving manufacturing solution for building material suppliers. Designed to produce both classic step-pressed glazed roof tiles and modern structural trapezoidal cladding panels on a single chassis, this dual-level line allows factory owners to double their product offering while cutting plant space requirements in half.
The Howann double-deck system handles pre-painted galvanized steel (PPGI), galvanized iron (GI), and aluminum coils from 0.2 mm to 0.8 mm in thickness. Running smoothly at flexible production speeds between 8 and 15 meters per minute, the machine is driven by a heavy-duty power setup (3 kW / 4 kW / 5.5 kW depending on profile configuration). Governed by an intelligent PLC touchscreen control panel, operators can easily switch profile deck modes, program step-pressing intervals, and execute precise post-shear cutting.
2-in-1 Compact Footprint: Integrates glazed tile step-forming rollers and trapezoidal panel passes vertically on one heavy frame, saving 50% factory floor space.
Independent Clutch Drive: Simple mechanical clutch selector allows operators to direct power exclusively to either the upper or lower deck without component wear.
Precision Hydraulic Step Pressing: Creates sharp, uniform tile steps on the upper deck to achieve authentic architectural glazed tile aesthetics.
Hard Chrome Anti-Abrasion Rollers: Precision-turned steel rollers are finished with hard chrome plating to prevent surface scratching on decorative color steel coils.
Coil Uncoiling & Guided Entry: Raw sheet steel feeds from the uncoiler through adjustable side-guiding rollers into the chosen upper or lower deck pass.
Progressive Roll Forming & Step Pressing: Flat strip is gradually shaped into trapezoidal ribs or pressed with hydraulic step dies to form glazed roof tiles.
PLC Optical Length Measurement: High-resolution encoder monitors feed length, signaling the hydraulic shear at exact programmed dimensions.
Residential Roof Renovation: Decorative color-coated glazed tiles for residential villas, cottage roofs, and pavilion structures.
Commercial Building Cladding: Heavy-duty trapezoidal roof and wall panels for commercial warehouses, industrial plants, and logistics parks.
Agricultural Sheds & Barns: Weather-resistant galvanized metal roofing for grain storage, livestock shelters, and equipment sheds.
Modular & Prefabricated Structures: Roof and side panels for container homes, site offices, and temporary shelters.
Optional Customizations
Profile Customization: Choose custom profile pairings for top and bottom decks (e.g., Glazed Tile + Corrugated, IBR + Glazed Tile).
Uncoiler System Options: 5-ton manual or hydraulic expansion decoilers with optional motorized coil loading cars.
Electrical Grid Matching: Adaptable for 220V, 380V, 415V, or 480V (3-Phase, 50/60 Hz).
Frequently Asked Questions (FAQ)
Q1: Can this double layer machine run glazed tile and trapezoidal profiles at the same time?
To optimize power distribution and ensure safe operation, the machine uses a clutch selector to run one deck level at a time, switching between profile modes in seconds.
Q2: How does the machine create the step pattern on the glazed roof tile?
The upper deck utilizes an integrated hydraulic step-pressing die controlled by the PLC, which automatically stops and presses the sheet at preset step intervals during forming.
Q3: What after-sales warranty and international certification standards are provided?
Howann equipment complies with EU CE standards and comes with a 1-year factory warranty, video outgoing inspection reports, and lifetime remote technical guidance.
