Profile Information
Sigma purlin is a structural steel profile widely used for roofing systems, steel buildings, solar structures, and industrial framework applications. Its reinforced shape provides excellent load-bearing strength while reducing material consumption.
Popular in the Middle East, Southeast Asia, Africa, and South America, M purlins are commonly produced from galvanized steel or black steel coils by an M purlin roll forming machine for continuous high-efficiency manufacturing.
How Does The Roll Forming Machine Work?
Machine Details
Hydraulic Decoiler And Leveling Machine
The decoiler feeds steel coils smoothly into the leveling machine. Through multiple leveling rollers, the material stress and surface deformation are reduced, ensuring stable feeding accuracy and improving final M purlin forming quality.
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 5/7/10 Ton | Expanding Range | 460-50mm |
Roll Forming Machine
The M purlin roll forming machine uses cast-iron stands and a gearbox driving system for heavy-duty continuous production.
Multiple forming stations gradually shape the steel strip into different M purlin sizes with stable transmission, precise forming accuracy, strong rigidity, and reliable long-term operation for structural applications.
| 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
The flying hydraulic cutting unit performs continuous non-stop cutting after roll forming. During cutting, the unit synchronously moves with the M purlin roll forming machine speed, creating relative stability between the profile and cutter for accurate cutting length and smooth production efficiency.
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.
