Beitou and Yangmingshan area with high contents is located in the northern part of Taiwan's famous hot spring area sulfur. However local sulfur-related research, especially for Beitou and Yangmingshan area is very rare. Various construction often quoted foreign data regarding atmospheric corrosion and corrosion design. The results are ofthen less than the design life, to have the rust damage. Therefore, to control the atmospheric corrosion of the metal structures in particularly important. This research project is focused on copper, aluminum and zinc wires exposing in Beitou and Yangmingshan area for field testing, according to the ISO and CNS specifications regarding of corrosion rate monitoring to analyze the structure and chemistry of the corrosion products, While to compare the three metal corrosion rates and the related corrosion mechanisms. The environment data from Beitou and Yangmingshan area is estimated to RH> 80% almost all year round, sea salt deposition less than 10 mg/m2/day 10km away from the coastline, but the area in the vicinity of the hot spring contain significantly higher chloride ions, and the SO2 content in hot spring area should be greater than the value cited from the relevant literature 200mg/m2/day. The atmospheric corrosion test results from Beitou and Yangmingshan region show that the classification to the ISO or CNS from the year-round test of copper, aluminum and zinc corrosion rate. However, the result also indicate a tendency for increasing.
