There are many instances where materials suffer from corrosion in unexpected environments. These can be propagated by a number of factors including chloride hydrolysis, bi-metallic corrosion and the unsuitability of certain natural materials in building applications. Wintech has decades of experience in the field of corrosion science and examining buildings and seeing examples where materials have failed. It is obviously imperative that where dissimilar materials are either in direct contact or electrical contact with each other these factors are taken into account. Simple mistakes can often have disastrous consequences and preventing these and understanding their initial causation is important.
