\nWhat Aluminum Signs Are Made Of\n<\/h2>
\n

Most aluminum signs fall into two main categories: aluminum composite and solid aluminum. The difference comes down to construction.<\/p>

Aluminum composite<\/a> uses two thin aluminum sheets bonded to a lightweight polyethylene (PE) core. This layered build keeps the panel rigid, reduces weight, and makes it easy to install. It is weather-resistant, dependable, and often the most economical option.<\/p>\n<\/div>

Solid aluminum<\/a> is a single sheet of metal, usually 2 to 4 mm thick, built for maximum toughness. It is heavier, stronger, and designed to hold up against demanding outdoor environments. This is the type of material used for traffic signs or long-term property signage.<\/p>\n<\/div>\n<\/div>
