It is often made of steel such as Q235 through hot-dip galvanizing treatment, and the common form is round steel screw, with diameters of φ12 and φ14, and φ16 can be used in special scenarios. Its core function is to connect adjacent purlins horizontally or obliquely, or connect purlins with columns to form a stable force-bearing structure, avoiding deformation and shaking of the bracket under natural loads. The installation form is divided into horizontal stay rods and cross diagonal stay rods, which are fixed with nuts through threads at both ends, and the tightness can be flexibly adjusted, suitable for various PV power station scenarios such as ground and roof.
