Insulation plates are typically used to break the electrical contact between dissimilar metals (e.g. fastening a stainless steel cleat onto a galvanised structure) and mitigate the risks of bi-metallic corrosion . Ellis offers a range of insulation plates to suit different cleat sizes. The plates are manufactured as standard in black polypropylene or black flame retardant VO zero halogen UV stabilised nylon (LSF).
