Installation Instructions

STEP 9: INSTALLING HAT CHANNEL ON ROOF AND SIDES OF BUILDING
The purlins on the roof and the girts on the sides of you building are Hat Channel. Most of the hat channel that you in-
stall will be 8’ long on buildings with frame sections on 4’ centers or 10’ long for buildings on 5’ centers and 12’ long on
buildings on 6’ centers..
See the chart below for the location and dimensions for the Hat Channel on the roof and sides of the building.
You can measure and locate each hat channel as you go or mark the locations of all the channels on the front and back
frame sections and snap a chalk line the length of the building to mark the hat channel locations on all of the interior
frame sections.
