Purlin / Structural Steel Profile for Eave Struts Making Machine
High-Precision Roll Forming Solution for Eave Struts and Structural Purlins
The Purlin / Structural Steel Profile for Eave Struts Making Machine is specially engineered to produce high-quality eave struts and structural steel purlins used in modern metal building systems. These profiles play a critical role at the transition between roof and wall structures, providing strong and reliable support at eaves and high side peaks.
Designed for efficiency, accuracy, and flexibility, this roll forming machine enables manufacturers to produce single-slope and double-slope eave struts, oriented either upward or downward, fully meeting the requirements of commercial, industrial, and agricultural steel buildings.
Are Eave Struts?
Eave struts are secondary steel framing members positioned where the roof meets the wall. They improve load transfer, enhance structural stability, and provide a secure connection between roof panels and wall systems.
Common features of eave struts include:
- Used at eaves and high side peaks
- Available in single slope and double slope
- Installed in up or down configurations
- Manufactured from galvanized or red oxide primed steel
- Cut to precise lengths for easy installation
