Profile Information
Z purlins are widely used as structural support members in steel buildings, warehouses, workshops, and roofing systems. Their offset flange design provides improved overlapping connection strength and efficient load distribution.
These profiles are commonly produced from galvanized steel or black steel coils by a Z purlin roll forming machine. Popular markets include Southeast Asia, the Middle East, Africa, South America, and Europe.
How Does The Roll Forming Machine Work?
Machine Details
Hydraulic Decoiler And Leveling Machine
The decoiler supports smooth coil feeding, while the leveler removes coil stress and improves sheet flatness through multiple rollers, helping the Z purlin roll forming machine achieve stable forming accuracy.
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 5/7/10 Ton | Expanding Range | 460-50mm |
Hydraulic Pre-Cut
The hydraulic pre cutting unit cuts the leveled steel strip before it enters the roll forming machine. This design reduces tooling costs, simplifies machine structure, and provides reliable length control. It is an economical solution for customers producing standard Z purlin profiles with consistent dimensions and stable production requirements.
Roll Forming Machine
The roll forming machine gradually shapes steel strips into Z purlins through multiple forming stations. The wall-panel structure combined with a chain driving system provides stable transmission, reliable operation, and cost-effective production for medium-thickness steel materials.
| Speed | 20m/min | Forming Station | 18 Stands |
| Motor Power | 7.5Kw | Shaft Diameter | 76mm, solid |
| Driving System | Chain | Roller Material | Gcr15,HRC58-62° |
| Frame Structure | Wall panel | Shaft Material | 40Cr heat treatment |
Hydraulic cut
This Z purlin roll forming machine uses a hydraulic stop-to-cut system after forming. During cutting, the roll forming section temporarily stops to prevent profile movement and maintain cutting accuracy. For customers requiring higher production speed, we also provide customized flying cutting solutions.
Safety Designs
Chain covers are installed to protect operators and extend chain service life. Full-machine mesh covers (slidable) provide visibility with safety. Flip-type covers ensure convenient access with enhanced protection.
Safety signs are applied to continuously alert operators.
PLC Control Cabinet & Encoder
In a cold roll forming line, the encoder works with the PLC to provide real-time feedback on material position and speed, ensuring precise feed, synchronized forming, and accurate length control for cutting and punching.
Production speed, product length, and quantity can be set on the control cabinet. The display language can be customized according to customer requirements.
Other Customization Details
The machine comes standard with a blue main color and orange accents. Other colors can be customized free of charge.
The default metal nameplate is Goalon, which can also be customized at no additional cost.
Basic Services
Professional Packing
Machines are packed in plastic film and labeled for easy identification and assembly, and secured inside the container with steel cables.
