Stainless steel, bronze, brass and aluminum are all found under the umbrella of metal signs, but the most commonly used metal for signage is aluminum. This metal is renowned for its durability and strength, making it an ideal choice for signs. Aluminum is also abundant and relatively inexpensive compared to other metals, making it a cost-effective option. When it comes to durability, metal signs can last up to three years outdoors and even longer if they are installed indoors.
Aluminum is a great choice for this purpose as it is strong and resistant to corrosion. Dibond signs are also popular as they consist of two sheets of aluminum composite that cover a solid polyethylene core. This combination of metal and plastic makes the Dibond material both incredibly durable and visually appealing. Coroplast is another material used in signage, which is also known as Corex or Coro.
This material is ideal for temporary signage such as political signs, special sales, construction signs in workplaces, directional signs for open days and other lightweight real estate signs. The 6mm Coroplast from Custom Sign Center is perfect for double-sided garden signs as colors and graphics won't leak out. When it comes to aluminum thickness, there are five main options available. The most common thicknesses are .012, .018, and .024.
Thin and small signs such as real estate signage are usually made with .012, while tougher traffic signs such as stop signs are made with .018. The thickest and strongest caliber is .024, which is ideal for signs that need to be rock-solid and won't break, warp, arch or crack. In conclusion, aluminum is the most popular metal used for signage due to its durability, strength, abundance and affordability. It comes in five different thicknesses depending on the type of sign you need, making it a versatile option for any signage project.
