What is galvanizing and why is it important for wrought iron?

Wrought iron means “worked iron” ie, bended and welded into shape, so the steel needs some protection after its been worked.  Hot dip galvanizing protects the steel from corrosion and is the best method of rust protection for wrought iron.

Below is the process used to prepare the steel for galvanizing:-

Metal preparation and galvanization

The steel is dipped in a bath of molten zinc which allows the zinc to permeate the surface and give a thick coating of protection and so less chance of a scratch reaching the bare metal and allowing rust to form.  It is key that the steel is cleaned and treated first as if the surface is dirty or not properly prepared it will not work, much like the paint job on a car!

The problem is that it can be hard to tell if something has been galvanized or not until the finish comes off or rusts.  All new wrought iron will look nice and shiny but only properly prepared and galvanized railings will still look good years later.  Here is an example of poorly prepared and non galvanized wrought iron:-

That is why we offer and recommend galvanizing on every wrought iron product we make Check out the video showing the actual galvanizing process on our YouTube page at https://www.youtube.com/watch?v=rIhAX_cPSXw
