c purlin roll forming machine factory

C purlin roll forming machines are used to produce C and Z purlins from metal coils. Purlins are structural framing members widely used in metal buildings and roofs. They are manufactured by roll forming mills from galvanized steel, stainless steel or aluminum coils.

C purlin roll forming machine factories design, manufacture and supply such roll forming equipment along with the necessary accessories. Key suppliers are located mainly in China.

This guide provides a comprehensive overview of c purlin roll forming factories covering:

Types of C Purlin Roll Forming Machines

C purlin roll forming machines are available in different configurations and levels of automation. The main types include:

Machine TypeDescription
Manual C Purlin LinesBasic machines for small productions with manual loading/unloading
Semi-Automatic C Purlin LinesEquipped with coil cart for automatic feeding
Fully Automatic C Purlin LinesAutomated material handling and cut-off
High Speed C Purlin Roll FormersOutput of 30-40 meters/minute
Customized C Purlin Roll Forming MachinesDesigned for specific purlin sizes and production needs

Key Considerations When Selecting C Purlin Roll Former Type

The choice of manual, semi-automatic or fully automatic c purlin roll forming machine depends on factors like:

  • Production output – Automatic machines have higher output rates of 30-40m/min versus 10-15m/min for manual lines.
  • Labor costs – Automatic roll formers require less workers for material handling and offloading.
  • Product dimensions – Customized machines needed for specialized purlin sizes and profiles.
  • Budget – Initial cost is lower for manual and semi-automatic lines.
  • Space available – Fully automatic purlin roll forming machines require more space.
  • Power costs – Automated lines consume more electric power.
  • Worker safety – Automated material handling reduces manual labor and improves safety.

Careful consideration of these parameters helps select the optimal roll former type for specific production requirements and budgets.

Main Components of C Purlin Roll Lines

C purlin roll forming machines are made up of different sections assembled in line for continuous production:

ডিকয়লারHolds and rotates the steel coil
Feeding systemFeeds coil sheet into roll former
Roll forming sectionForms C or Z purlin profile progressively
Hydraulic systemPowers the rolling process
পাঞ্চিং ইউনিটPunches holes for bolts
Cut offCuts purlins to length
Stacking tableCollects cut purlins
Control panelControls speed, size changes etc.

Additional components like punching units, counters, printers etc. can be integrated as per application requirements. Correct configuration of the different sections is crucial for efficient purlin production.
