A double layer roll forming machine is an industrial metal forming system that produces two different panel profiles on one machine. The two forming lines are stacked vertically. They share one decoiler, one cutting system, and one PLC control system.
Instead of buying two separate machines, operators can switch between profiles in under 5 minutes via PLC selection — compared to 2–4 hours for a full roll change on a single layer machine.

BELI vs Chinese Manufacturers
| Recurso | Typical Chinese Maker | PERFILAGEM BELI |
|---|---|---|
| PLC | Domestic or unbranded | Siemens |
| Inverter | Domestic or generic | Yaskawa |
| Rolamentos | Unbranded or domestic | NSK (Japan) |
| Roller material | GCr15 or 45# steel | 42CrMo (4140) |
| Roller treatment | Chrome (variable) | CNC machined + hard chrome |
| Roller runout | ±0.05 mm or uncontrolled | ≤±0.03 mm |
| Shaft hardness | Not specified | HB220–260 |
| Cutting blade | Generic Cr12 | Cr12Mov, HRC 58–62° |
| Factory testing | None or brief | 48-hour run test |
| Codificador | Unbranded | Omron / Koyo |
| Spare parts | Usually none | Full kit included |
| Garantia | 12 months (limited) | 24 months |
| Overseas install | Usually not available | Available (5–10 days) |
| After-sales | WhatsApp only | Dedicated manager + remote support |
Bottom line: Many Chinese makers cut costs with unbranded parts, cheaper steel, and no factory testing. BELI charges more because Siemens/Yaskawa/NSK components and 48-hour testing cost more — but they last longer and break down less.
BELI vs US / European Manufacturers
| Recurso | US / European Maker | PERFILAGEM BELI |
|---|---|---|
| Machine price | USD 120,000–250,000 | USD 35,000–80,000 |
| PLC | Siemens / Allen-Bradley | Siemens |
| Rolamentos | SKF / Timken / FAG | NSK (equivalent) |
| Roller material | 4140 / D2 / tool steel | 42CrMo (4140 equivalent) |
| Lead time | 16–24 weeks | 90 working days |
| Custom profile design | $5,000–15,000 extra | Included |
| Tensão | Standard (e.g., 480V/60Hz) | Personalizável |
| After-sales response | 1–4 weeks (parts) | 3–5 days (air freight) |
| Training | Usually included | Included (up to 2 operators) |
| Spare parts cost | 2–4× higher | Standard pricing |
| 5-year total cost | USD 180,000–350,000+ | USD 55,000–110,000 |
Bottom line: US and European machines cost 3–5× more for similar specs. Same core brands (Siemens, NSK), a fraction of the price. BELI also provides overseas installation and a 24-month warranty that beats the Chinese 12-month standard.

❓Perguntas frequentes (FAQ)
It is a machine that produces two different metal profiles on one base. Common combinations: trapezoidal + corrugated, IBR + step tile, roof panel + wall panel. The two layers share one decoiler, one cutter, and one PLC. They cannot run at the same time — you switch layers on the PLC in under 5 minutes.
Starting from USD 35,000 FOB Shanghai. Price depends on profile types, material thickness, and optional equipment. Popular add-ons: coil car (1,500–3,500),autostacker(1,500–3,500),umutostumcker(8,000–20,000). Contact BELI for a confirmed quote.
Galvanized steel, color-coated steel, ZINCALUME®, COLORBOND®, aluminum, and stainless steel. Thickness: 0.25–0.8 mm. Yield strength: up to 550 MPa. Feed width: 750–1250 mm (varies by profile). Custom configs available.
A single layer machine makes one profile. To switch, you need a full roll change (2–4 hours). A double layer has two stacked forming lines sharing one base. You switch profiles in under 5 minutes via PLC. It saves ~50% floor space e 30–40% investment vs buying two machines.
