Question from Ralph Jones
I am currently involved in a non toxic construction project and was wondering if you could give me some information on galvanised metal. Ive heard metal is a good material to use for the chemicaly sensitive in general especially stainless steel. But are galvanised metals still safe? I cant seem to find any information on the process and was wondering whether by making the metal weather proof it was made toxic in some way? Is galvised steel toxic? Or potentially harmful to the chemicaly sensitive?
Thank you so much for your time.

Galvanizing is the process of coating iron or steel with a thin layer of zinc to prevent the metal from rusting. There are two methods: “hot-dipped”, which consists of passing the continuous length of metal through a molten bath, followed by an air stream “wipe” that controls the thickness of the zinc finish; and “electro-galvanizing”, which fuses the zinc to the metal electrolytically.
I don’t see anything toxic about this.
