Greetings Michael Painter. First of all, the white scale is corrosion that has occured from the dissimilar metals reacting. Aluminum and steel will always react and corrode when put together.Even steel made in different batches can have this problem when put together. Your idea of re-fastening the mesh with stainless hardware is a good one but I would add the spray product called ECK found at www.vannay.com . ECK will isolate the different metals keep moisture out and provide zinc as a sacrificial metal preventing corrosion. Electrolysis is a very common problem when aluminum and steel are put together. Let me know if I can help you in any other way. Rich Nay
