PEB Awareness

Up to 50% of the cost can be saved for PEB having larger clear spans, whereas such clear-span structure is impossible in concrete structures

Secondary Framing

Purlins, girts and eave struts are secondary structural members used to support the wall and roof panels. Purlins are used on the roof; girts are used on the walls and eave struts are used at the intersection of the sidewall 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 are available in high grade steel conforming to ASTM A 607 Grade 50 or equivalent, available in 1.5 mm, 1.75 mm. 2.0 mm, 2.25 mm, 2.5 mm and 3.0 mm thickness. pre-They come with a pre-galvanized finish, or factory painted with a minimum of 35 microns (DFT) of corrosion protection primer.

Minimum yield strength is 34.5 kN/ cm2
