Is CEDO doors outer coating rustproof?
Aluminum is rustproof and anti-corrosive. And CEDO uses galvanized hot dipped steel. These two metals are both pre-painted with two coats of baked polyester paint, according to door models, which add up to their resistance to rust and corrosion. Furthermore, all steel hardware components are made of G60 hot dipped galvanized steel, providing an improved protection against rust.
