摘要

There are many advantages to roof system utilizing Z-sections topped with metal sheathing. The system is structurally efficient, easy to install, and utilizes recyclable material. Two of the greatest advantages of the Z-section is that its shape allows for nesting - which facilitates transportation and allows for lapping in multiple span systems. For the Z-sections to be lapped, the bottom flange of the Z-section is placed at the top flange of the rafter and sheathing is attached to the top flange of the Z-section. Consequently, loads applied at the sheathing elevation must be transferred over the depth of the Z-section to the rafter elevation. To limit lateral movement of the system, lateral restraints must be applied.
