Visão geral do produto

The Sigma Purlin Roll Forming Machine is a high-performance automated system designed for producing Sigma shaped steel purlins with excellent precision and efficiency. Built for flexibility, this machine supports continuous manufacturing of structural profiles widely used as secondary support members in roofing and wall systems for modern steel buildings.

Sigma profiles are formed from cold roll-formed hot-dip galvanized steel (S450 grade), ensuring a minimum yield strength of 450 N/mm² for superior rigidity and long-term durability. The Sigma Purlin Roll Forming Machine integrates punching, forming, and cutting into one streamlined production line, enabling manufacturers to achieve accurate, consistent results with minimal manual intervention.

With its stable performance, multi-purpose capability, and reliable output quality, this machine is an ideal solution for fabricators looking to expand or upgrade their structural purlin production while maintaining high standards of strength and efficiency in steel construction projects.
