Fly brace, Cee Rafter, Tophat battens
Simple answer….Fly Braces stop Cee sections twisting – A Fly Brace is a strap, angle or bar that runs from the flange of a rafter, main column or end wall column to a roof or wall purlin/batten and therefore restrains the section laterally.
What do they do? Essentially they prevent a column or rafter from twisting or rotating when under load.
