Double Layer Glazed Tile Roll Forming Machine | Dual Profile Metal Roof Tile Production Line

If you run a roofing workshop or metal panel factory and frequently receive mixed orders for classic glazed tiles and trapezoidal / corrugated roof sheets, the double layer glazed tile roll forming machine is one of the most cost-effective roll forming solutions. Instead of purchasing two separate roll forming lines, this dual-deck machine integrates two independent forming sections on one heavy-duty frame. You can switch between two roofing profiles without changing rollers, saving workshop floor space, capital investment and daily maintenance work.

Many new buyers misunderstand double-layer roll formers. It does not produce two stacked insulated panels in one pass. It has two separate roller groups: one upper deck and one lower deck. One run makes glazed step tiles, the other run makes trapezoidal roof panels or corrugated sheets. This flexibility makes it very popular for small-to-medium roofing manufacturers, prefab suppliers and local roofing contractors with diverse project orders.

Complete Line Structure

The full automatic double layer glazed tile line covers coil feeding to finished panel output, with independent forming and cutting for each layer:

• Hydraulic decoiler: 5–10 tonne load capacity, hydraulic expansion mandrel for PPGI, GI, PPGL and aluminum coils; optional double decoiler for non-stop coil change
• Entry guiding and leveling unit: Multi-roller leveler removes coil camber, twist and edge bending before forming, avoiding ripples and uneven tile ribs
• Upper & lower roll forming stations: Two independent forming decks. Rollers are GCr15 or Cr12MoV steel, quenched to HRC 58–62 and hard chrome plated to prevent scratches on pre-painted color steel surfaces
• Hydraulic cutting system: Independent hydraulic cutter for each layer, cutter blade Cr12MoV, clean burr-free cut, fixed-length cutting controlled by PLC
• Run-out table: Two separate discharge tables, support manual stacking or optional automatic stacker, protects painted coating
• PLC + HMI control cabinet: Store multiple production recipes, set length, speed and batch count on touch screen; frequency converter for stepless speed adjustment
• Safety guard & emergency stop system: Full safety fencing, interlock protection for operator safety

Core Advantages of Double Layer Glazed Tile Machine

Save workshop space and equipment budget

One machine replaces two separate roll formers. It occupies roughly half the floor space of two single-layer machines, which is a huge advantage for factories with limited workshop area. You only pay for one main frame, one decoiler and one control system, cutting your initial investment significantly.

Quick profile switching, flexible for mixed orders

Switching between glazed tile and the second profile only needs you to select the saved recipe on HMI, no heavy roller disassembly. When you receive villa glazed roof orders and warehouse trapezoidal sheet orders at the same time, you can arrange production flexibly without waiting for tooling change.

Good surface finish, stable glazed tile shape

Glazed tile has curved step ribs, which require gradual, multi-stage forming. Precision machined chrome-plated rollers distribute forming stress evenly, reducing paint cracking and tile twisting. The finished glazed tile has neat overlapping edges, good waterproof performance and consistent decorative appearance.

Low labour and maintenance cost

Normally 1–2 operators can run the whole line. Shared decoiler, leveling unit and control system mean fewer hydraulic pumps, motors and spare parts to maintain. Wear parts like cutting blades, seals and sensors are standard and easy to source.

Wide application range

Finished glazed tiles are widely used for villa roofs, church roofs, tourist pavilions, residential buildings and decorative roofing. The second profile (trapezoidal / corrugated sheet) fits warehouses, factories, poultry sheds, carports and wall cladding. One machine covers both decorative and industrial roofing demand.

What You Should Check During Machine Acceptance

Do not only test one profile; verify both layers carefully:

1. Dimensional consistency: tile rib height, effective width and overlapping edge size for both profiles
2. Length accuracy: run continuous batches and check cutting tolerance at different speeds
3. Surface quality: no roller marks, scratches or paint peeling on PPGI glazed tiles
4. Straightness & twist: check panels on flat table; glazed tiles are easy to twist if the frame or shafts are not rigid enough
5. Recipe repeatability: save two recipes, switch back and forth, confirm the profile stays stable
6. Hydraulic cutting performance: no burr, no deformation at the cut end

A common low-quality defect: one layer runs well while the other layer produces wavy panels. This comes from weak frame rigidity and misaligned roller shafts.

FAQ

Q: Can this machine run both layers at the same time?

A: No. It is dual-profile, not simultaneous dual production. You run either the glazed tile layer or the second profile layer in one batch.

Q: Can I customize the two profiles on the double layer?

A: Yes. The most popular match is glazed tile + trapezoidal IBR panel. We can design custom roll tooling for your required profile drawings.

Q: What is the difference between double layer glazed tile machine and single glazed tile machine?

A: Single-layer machine only makes glazed tile. Double layer adds a second roofing profile on the lower deck, better for factories with mixed order types. If you only produce glazed tiles all the time, a single-layer model is more economical.

Q: What spare parts should I prepare?

A: Hydraulic cutting blades, oil seals, proximity sensors, drive chains and contactors. We provide a standard spare parts package together with the machine.

Q: What after-sales support is included?

A: One-year warranty, operation manual and operation video, overseas commissioning service on request, lifelong technical guidance and spare parts supply.
