Zinc Coating Thickness Quality Control of Angle Steel Tower Materials Based on Statistical Method

As an important quality index of high voltage electricity transmission tower, zinc coating thickness detection and quality control is more and more attention in recent years. The coating thickness and uniformity of tower materials provided by the suppliers are tested through the traditional method by the power department, the detection precision of this method is low efficiency and analysis results is not returned objectively to help superior evaluation. In this paper, zinc coating thickness detection and quality control system of tower materials based on statistical method are developed, through coating thickness and uniformity tested, the test results are returned to the competent department timely, the analysis of test data is completed automatically by this system. Therefore the zinc coating quality of the tower materials caused safety issues is avoided effectively and contributed to superior evaluation reasonably.
