Frequently Asked Questions (FAQs) About C Purlin Machines

What’s Stronger: Z or C Purlin?

Z purlins are structurally stronger and commonly used in roofing and wall framing where overlapping joints are needed for continuity. C purlins are lighter and typically used for secondary structural support in walls and floors. Their non-overlapping nature limits span length compared to Z types.

How Much Power Does a Roll Forming Machine Use?

Power consumption depends on machine size and configuration. Standard C purlin lines consume between 2.2 kW and 15 kW. Larger, fully automated systems with hydraulic punching and servo feeding may require 30–50 kW.

What Size C Purlin Is Suitable for a 6m Span?

For a 6-meter span, typical specifications include dimensions of 152 mm (depth) × 64 mm (flange) × 17 mm (lip), with a thickness of 1.9 mm and a length of 6 meters. Always consult structural engineers to verify load requirements based on local climate and building codes.

Can You Overlap C Purlins?

No, C purlins cannot be overlapped continuously due to their symmetrical profile. Unlike Z purlins, which allow lapping for longer spans, C purlins must be butt-jointed, requiring additional supports at connection points. For extended runs, Z-shaped sections are preferred.
