Abstract
—Corrosion of steel pole is a serious issue as they used steel pole to support overhead power line in distribution. A lot of money and time are spent for maintenance and repair of existing steel pole. This paper presents investigation on various coating technologies of steel pole for initial corrosion activity. Five types of coating were used on steel samples; epoxy, VEF polyglass, galvanized, epoxy galvanized and polyglass galvanized. The accelerated ageing test, salt spray test and water absorption test were used to determine coating degradation and severity of corrosion process. It was found that, the corrosion rate for epoxy galvanized and VEF polyglass galvanized were higher as the samples were undergoing accelerated ageing test. While VEF polyglass steel showed higher percentage of weight loss during salt spray test. In addition, the results of water absorption behavior showed that epoxy steel gave higher average of absorption rate. The results obtained lead to low degradation of coating as the corrosion rate seem to be uniform
