- Zinc in relation with timber
A low or non-acid solid, natural and non treated timber deck, that is, with a pH of between 5 and 7 is compatible with zinc and can be used as a direct support.
- Zinc in relation with other metals
Contact between zinc and other metals must take into account the electro-chemical reactions caused by a difference in electrical potential between the surfaces of the metals. Therefore a certain number of contacts are acceptable whilst others must be avoided.
