Uniformity of zinc coating is critical for ensuring consistent and reliable corrosion protection across the entire surface of steel. A uniform coating means a consistent thickness, preventing localized areas of weakness where rust could initiate and spread. Tests like the Preece test (copper sulfate dip) visually assess uniformity by revealing areas with thinner or no zinc. Uniformity guarantees predictable and extended service life for galvanized steel products, maximizing their resistance to environmental degradation. It's a key aspect of quality control and adherence to galvanizing standards, ensuring long-lasting protection in diverse applications.
