When the Government (or their architects) refuse to listen to contractors regarding materials appropriateness for the application, there is always going to be issues. It is not apolic (brand name) or aluminium composite cladding in any form, that is what it should have been, it is easy to replace, does not rust and is cost effective. What is installed is Vitreous Enamel, like your old camping mug, cannot be altered once it's made, very susceptible to damage in transit and the damage cannot be repaired, a whole panel needs to be replaced, any chips will rust. But try telling an architect. They had too put them in as there were no replacements and it had to be closed up to commence internal works.
Everything else 100% :approve:
