PMI Z and C Purlins

A purlin is a horizontal structural element used in roofing to support the load from the roof deck or sheathing. Designed for architectural and structural engineering applications, our purlins are supported by primary rafters, building walls, and steel beams. Z-purlins and C-purlins are commonly supported by internal walls made from cold-formed or roll-formed steel sections, which can be lapped and nested at the supports. We offer fabrication and erection services based on the detailed specifications provided by our clients.
