百密得抗腐蚀紧固系统在单层轻钢屋面中的应用

Application of Bi-Metal Corrosion-resistant Fastening System in Single-layer Light Steel Roof

单层轻钢屋面系统紧固件的腐蚀,将严重影响系统的工程质量。本文探讨了紧固件腐蚀的类别后,指出重视紧固件的抗腐蚀性,对确保轻钢屋面系统的工程质量十分重要,抗腐蚀性强的百密得奥氏体不锈钢复合螺钉和百密得碳钢涂层钉,必将在单层轻钢屋面系统工程建设中获得推广应用。

The corrosion of fasteners in single-layer light steel roof system could seriously affect the construction quality. The article discusses the corrosion types of the fastener, points out that the fastener＇s corrosion resistance is a determining factor for the quality of light steel roof system. Bi-Metal austenitic stainless steel screws and Bi-Metal carbon steel coated nails have strong corrosion resistance. They will apply popularly in single-layer light steel roof system projects.
