Product Applications  Building Products  Purlins and Girts


These are horizontal structural members in a roof. They support loads from the roof deck/sheathing, and are commonly used in metal building systems. Being important structural elements, they must be manufactured exactly to specification.

PURLINS are thin-gauge lightweight construction elements produced by roll forming which are mainly used as roof purlins, but also as secondary girders. Purlins can be produced in an infinite variation, ranging from the smallest to the largest possible profile type, and in different overall heights.
