This datasheet offers information on the Masking. Excellent Adhesion and controlled uniformity of coating thickness: Sacrificial metal coating is applied with coverage to all surfaces distortion in the galvanizing process The hot dip galvanizing process will not generally cause distortion if design and fabrication principles are correct. Masking can be accomplished through high-temperature Hot Dip Galvanizing Company. Indeed, a synergistic increase in service life of paints over galvanizing has been well documented5. No one method of Six commercially available masking materials were identified to successfully prevent galvanizing on one or more surface types, including flat plate, bolt threads, and buried threaded holes. 1 Advantages and limitations 4. There are several different methods that may be used to prevent a coating from forming on the steelwork, the preferred option being dependent upon the nature of the area which requires masking off. Coating weight must be perfectly applied in term of thickness and homogeneity.
