Which component is used to align purlins and girts in a straight line?

Explanation:
Brace rods provide the diagonal tension needed to keep the roof and wall framework true as it goes up. When installed across the frame and tightened, they pull purlins (roof horizontal members) and girts (wall horizontal members) into a straight, square line, preventing bowing or skew during erection and helping the entire assembly stay aligned as the structure progresses. Sag rods aren’t used for aligning the frame, base angle serves a different structural/finish purpose at the base, and an eave strut supports the eave rather than aligning horizontal members, so brace rods are the tool that maintains that straight-line alignment of purlins and girts.
