• Roofing panels (PBR, R-Panel, standing seam)
• Secondary framing components

This case study highlights how a Louisiana-based fabrication company successfully implemented roofing and purlin roll forming production to supply large-scale industrial projects across:

• Baton Rouge
• Lake Charles
• New Orleans industrial zones

👉 This is a practical, real-world example of how roll forming integrates into Louisiana’s industrial supply chain.
