उत्पादन वर्णन
C and Z purlins are horizontal structural members used in roofing and walls to support loads from the roof deck or sheathing. C purlins have a C-shaped cross-section with a back and two flanges, suitable for applications like wall and floor joists and shorter spans. Z purlins have a Z-shaped cross-section that allows them to overlap, providing superior strength, which makes them ideal for longer spans and heavier loads on roofs.
