When properly specified, finished, and maintained, our steel windows and doors are highly resistant to rust and corrosion. Unlike traditional mild steel profiles that can be prone to mill scale and surface oxidation, the Metro M40 System uses galvanized steel cold-rolled to European standards, which provides a strong base for corrosion protection. Combined with our zinc-rich epoxy primer and two-pack paint finish, the result is a system built for long-lasting performance — even in challenging environments.
