Solution

We provide customized cold roll forming production lines. According to the metal profile requirements of different industries, we realize one-stop automated production from uncoiling, forming and cutting to assembly. Below are the typical applications and values in four core industries:

solution1

HVAC & Ducting Systems

Application of Our Equipment Production lines for TDC/TDF flanges, PDF3 flanges, duct manufacturing machines, corner forming lines, C/U-type duct connectors, round duct machines, etc.

Customer Pain Points Solved

- Low efficiency and poor precision of flanges produced by low-end machines → Fully automatic forming, high-speed output at 12m/min with precision of ±0.2mm

- Project rework caused by insufficient airtightness → Integrally formed flanges with gearbox transmission, completely eliminating air leakage

- High labor costs and recruitment difficulties in Europe → Only one operator required for the entire line, saving more than 60% labor cost

Typical Solution

PDF3 automatic duct production line, which processes raw coils into finished ducts in one continuous process, meeting EU Class D airtightness standard.

Storage & Shelving Systems

Applications of Our Equipment

Manufacture shelf uprights (C-type, Ω-type), rack beam forming machines, vertical rack forming machines, panel forming machines, etc.

Customer Pain Points Solved

· Wide variety of shelf profiles with long mold change time → PLC one-click profile switching, storing 50 specifications and changing within 3 minutes

· Poor straightness of long profiles leading to difficult installation → 22-station roll forming main unit + high-rigid frame to ensure full-length straightness

· Large springback during thick plate (1.5–2.5mm) forming → customized rolls + gearbox transmission to control springback and ensure accurate hole positions

Typical Solution

Heavy-duty shelf upright production line integrated with servo motor and flying saw cutting, with hole spacing error of ±0.5mm over the full length.

solution3

Fire Damper

Applications of Our Equipment

Production of fire damper blades (hollow / solid), damper frame forming machines, damper blade forming machines.

Customer Pain Points Solved

● High requirements for blade airtightness and fire resistance → hollow blades formed in one-step edge sealing with no leakage paths

● Frequent order changes in small batches and multiple specifications → quick roll change design, suitable for flexible production

● Difficulty in forming stainless steel and rapid mold wear → CR12MOV rolls with HRC62–64 hardness, service life three times longer than ordinary rolls

Typical Solution

Dual-coil hollow blade roll forming line with simultaneous feeding of two coils, doubling efficiency and ensuring consistent blade rigidity.

solution4

Building & Construction

Applications of Our Equipment

Production of light steel keels (C/U type), solar PV brackets (C/Z type), wall and ceiling frames, stud forming machines, cable trays, door and window frames, etc.

Customer Pain Points Solved

● Excessive on-site cutting and serious material waste at construction sites → online fixed-length cutting with zero waste

● High mold cost due to different profile sections for different projects → customizable rolls, one set of rolls for one section with low long-term amortized cost

● Large production volume and tight delivery schedule → 12m/min high-speed line supporting 24-hour continuous operation

Typical Solution

High-speed light steel keel production line integrating uncoiling, forming and cutting, ideal for prefabricated buildings.
