The light steel keel machine is a special equipment for cold bending forming. It processes steel strips into light steel keels (U-shaped/C-shaped/L-shaped/roof and floor keels, etc.) through continuous rolling. It is suitable for scenarios such as building decoration, integrated houses, and light steel villas. It is also a popular metal forming equipment for export. It is divided into semi-automatic and fully automatic CNC models. The CNC model is the mainstream for export.
1. Core general parameters (industry standard model, suitable for export)
Category: General parameter range, Best-selling preferred parameters (export commonly used)
Raw material specifications: Steel strip thickness 0.3~1.2mm, width 20~200mm. 0.4~1.0mm, width 38~100mm (suitable for regular keels)
Forming speed: 8~22m/min. 12~18m/min (CNC speed adjustment, accuracy consideration)
Rolling die: 12~18 passes, Cr12MoV quenching (HRC58~62). 16 passes, split die (easy to replace)
Power configuration: Motor 5.5~15kW, 380V/220V selectable. 7.5~11kW, variable frequency speed regulation
Cutting system: Hydraulic cutting, no burrs at the cut (precision ±1mm)
Control system: PLC CNC/manual control. Touchscreen PLC CNC (Chinese and English interfaces, fixed-length cutting)
Overall machine size: Length 6~12m × Width 0.8~1.2m × Height 1.2~1.5m. Length 8~10m × Width 1.0m × Height 1.3m (standard model)
Equipment weight: 2~5T. 3~4T (steel structure frame, stable and not shaking)
2. Main models and application scenarios (core for export selection)
1. Fully automatic CNC light steel keel machine (export main model)
Complete line including feeding rack + leveling + rolling forming + fixed-length cutting + feeding rack. PLC touch screen fixed-length (1~6m adjustable). One person operation. Suitable for batch production. It is the mainstream model for export in Europe, Southeast Asia.
2. Semi-automatic light steel keel machine
No automatic fixed-length/feeding, manual cutting. Low price, small footprint. Suitable for small workshops, small batch processing. Suitable for low-budget markets.
3. Multi-specification change die keel machine
One set of equipment can change dies to process various keels such as U/C/L types. No need to purchase separate machines. High cost performance. Popular for export customization models.
3. Key export adaptation configurations
1. Voltage/forming system: Supports 380V/220V, 50Hz/60Hz, suitable for global power grids, standard pure copper motor.
2. Operating interface: Chinese and English dual-language touch screen, simple parameter adjustment, no need for professional technicians.
4. Core processing adaptation
– Adapted raw materials: Galvanized steel strip, cold-rolled steel strip, color steel strip (commonly used in construction);
– Processed keels: U-shaped sky and ground keels, C-shaped vertical keels, L-shaped corner keels (conventional specifications 38/50/75/100mm);
– Processing effect: Rolling without warping, cutting without burrs, size tolerance ±1mm, meeting construction standards.
5. Equipment layout & footprint Standard fully automatic model overall layout: feeding rack (1.5m) + main unit (8-10m) + receiving rack (1m). The total area is 11-13m in length × 2m in width. It can be installed on a flat concrete floor without the need for pre-buried or fixed installation.
