The connection between hemmed purlins 200 and the color-coated steel tile roof requires temporary drilling based on site conditions, without pre-drilling holes 201 (holes 201 are typically arranged in a row). This makes on-site construction inconvenient and inefficient. Furthermore, the hemming of the hemmed purlins is largely reserved for on-site adaptation, resulting in significant material waste and increased costs.
