SECONDARY FRAMING

Purlins, Girts and Eave Struts/Purlin are secondary structural members used to support the wall and roof sheets. Purlins used on the roof, girts are used on the walls and eave struts are used at the intersection of the side wall and the roof.

SECONDARY MEMBERS HAVE TWO OTHER FUNCTIONS:

Act as struts that help in resisting part of the longitudinal loads that are applied on the building such as wind and earthquake loads.
Provide lateral bracing to the compression flanges of the main frame members thereby increasing frame capacity.

Purlins, Girts and Eave Struts/Purlin are available in 1.5 mm, 2.0 mm, 2.5 mm and 3.0 mm thickness with a pre-galvanized finish.
