- Abstract
The black-dot defects on galvanized thick sheet surface after galvanizing line, which is the traditional construction materials with 1.5mm thickness, was studied. Characterizations of the research samples were carried out using a SEM in order to understand the causes of the defects. The results showed that the local oxidation mainly leaded to the surface defects. What's more, the bad conditions of touched rollers also results in the black-dot. The paper also discussed the terms of settlement.
