Z-Purlins

Z-Purlins are cold-formed steel components designed to span between a building’s rigid frames, supporting both the roof and wall panels. Their unique “Z” shape allows them to overlap at joints, creating longer continuous spans that increase strength while reducing material waste.

Indaco Metals fabricates Z-Purlins to precise lengths and gauges to meet your project’s engineering requirements. Whether you’re building an agricultural barn, warehouse, or commercial facility, Z-Purlins provide the secondary framing that ties the structure together and ensures lasting stability.

Core Specifications
  • Profile: Distinctive "Z" shape, allowing for the unique ability to overlap and nest, creating continuous spans for enhanced strength over supports.
  • Primary Application: Exclusively used as secondary framing members in **roof systems** of metal buildings. They provide critical support for metal roofing panels and efficiently transfer roof loads to the primary framing.
  • Gauge Options: Available in robust steel gauges to meet diverse structural and load requirements: 14/16 gauge, 12/14/16 gauge
  • Web Depths (Height): Choose from various web depths to suit your span and structural needs: 4", 8", 10"
  • Flange Widths: Available with different flange widths for optimal attachment and stability: 2", 2.5", 3.5"
  • Custom Lengths: Fabricated to your exact required lengths to minimize waste and ensure precise fitting on site.
  • Quality Material: Made from durable, cold-formed steel for exceptional strength-to-weight ratio.
  • Applications: Roof purlins, wall girts, and bridging members

Customer Fit Snapshot

Z-Purlins are best for:

  • Contractors and builders needing strong, reliable secondary framing for large metal buildings
  • Developers constructing warehouses, manufacturing facilities, or distribution centers
  • Agricultural customers building barns or machine sheds with long roof spans

If your project requires lighter framing or smaller buildings, C-Purlins or tubing may be more appropriate. For large, engineered buildings, Z-Purlins are the trusted choice.
