Wrought iron gates are usually prone to rust, therefore, a variety of protective measures are provided for these gates to improve their service life and aesthetics. Here are some ways:

a) primer: This is a kind of rust inhibitor, but the protection is poor. In this method, there is an aerosol that is sprayed onto the surface using a can or paint nozzle. This results in uneven coverage, and often the metal hasn't done much to prepare it. This also requires regular maintenance, and the surface needs to be trimmed.

b) Electronic coating: This is a better way to prevent rust on wrought iron doors in Perth. In this case, a water-soluble organic fluid similar to paint is used. In this case, immerse the part in the solution. An electric charge passes through the solution, which binds the metal to the paint. However, before coating the metal, it also needs to be cleaned and prepared.

c) Hot dip galvanizing: This is a rust prevention method for heavy duty projects. This protects the metal from water, soil corrosion, and atmospheric elements. In this case, the metal is immersed in molten zinc. The zinc can then permeate the surface. However, in galvanizing, preparation is the main part of the process. It consists of caustic soda cleaning, then rinsing, then pickling. After pickling, it also needs to be rinsed and then dipped into the flux solution. After completing this preparation, it is necessary to galvanize in a molten zinc bath. It's only cooled after that. If the galvanizing effect is not good, there will be foaming or peeling of the finish layer. Sometimes blistering occurs due to rust.
