Application of M Purlins
M-type purlins are widely used in roof structures.Sleeves are used to connect shorter lengths or assemble double-span staggered purlins
Maintain a gap of approximately 15 mm between the purlin and the truss
Eaves beams feature an angled top flange, eliminating the need for separate profiles at roof-to-wall junctions
Note: Details for fully automatic C/U/M purlin lines will be provided in the next article. For inquiries, please contact us anytime.
Frequently Asked Questions
1. Q: What experience do you have in manufacturing C/Z purlin roll forming machines?
A: We’ve successfully delivered C/Z purlin lines to clients in India, Serbia, the UK, Peru, Argentina, Chile, Honduras, Bolivia, Egypt, Poland, Russia, Spain, Romania, and more. It remains one of the most sought-after machines in our portfolio.
2. Q: How many profiles can this equipment produce?
A: It supports production of C, Z, U, and Sigma purlins. For each profile, multiple sizes are available—widths from 80 to 300 mm and heights from 50 to 100 mm. Material thickness can range from 1.5 mm to 3 mm, making this a versatile and cost-effective solution.
3. Q: What is the production speed?
A: The standard forming speed is approximately 20 m/min for 1.5 mm thickness with flying cut. For 3 mm thickness, the speed reduces to around 15 m/min.
