Another important attribute of aluminium grating is its resistance to corrosion. Unlike steel, which can rust and deteriorate when exposed to moisture and other environmental elements, aluminium forms a protective oxide layer naturally. This makes aluminium bar grating particularly advantageous for outdoor applications or in marine environments, where exposure to saltwater can severely impact other materials. By choosing aluminium grating, businesses can reduce maintenance costs and extend the lifespan of their installations.
