The invention provides a galvanization method of iron tower scattered components, and relates to the technical field of galvanization. The galvanization method of the iron tower scattered components comprises the following steps of S1, surface pretreatment, wherein firstly, whether the surfaces of the components are provided with paint, grease and other attachments is checked, the components are classified, the components with dirt existing on the surfaces are washed through a cleaning agent, after washing, a steel wool is used for brushing the surfaces of the components, finally, deionized water is used for washing, and then drying treatment is carried out; and S2, oxide layer treatment, wherein after the attachments on the surfaces of the components are cleaned, abrasive paper is used for grinding the surfaces, the rust on the surfaces of the components is removed, and a clean cleaning cloth is used for wiping off scrap iron remaining on the surfaces of the components. After component acid pickling, sand blasting treatment is carried out, the surfaces of the components have the good mechanical strength and attaching force, salt film layers and zinc layers on the surfaces of the components can be tightly attached to the surfaces, the component quality is greatly improved, and the service life of the components is prolonged.
