Cable bracing are also called tie rods. There are two types of straight tie rods and diagonal tie rods. They are the out-of-plane support points of the purlin. Therefore, the tension on the tie rod is the horizontal load that the purlin bears. It is generally made of Q235 round steel. The whole roof purlin is connected into a whole, and the oblique pull rod can be used for supporting and supporting after being sleeved on the round pipe.
