[0002] Metal roofing has been used in China for a long time and is now widely used in various construction projects. The market has created a huge demand for high-quality roofing materials and technical systems. Prefabricated metal roofing is an excellent roofing material that can be widely used in various types of buildings. However, compared with traditional building roofs, prefabricated metal roofs have many construction joints due to the splicing process of the components. If these joints are not properly treated, they will cause seepage and leakage. Therefore, proper waterproofing is a key point for prefabricated metal roofs.
