Outdoor Metal Signs are Durable, Practical, and Look Good Everywhere


Aluminum is great for signs that are exposed to heavy traffic, rain, and heavy equipment areas. This solid metal sign type comes with a baked on enamel finish that both offers protection and beauty to the sign. Aluminum is available in three grades: standard .040" gauge, medium duty .063" gauge, and heavy duty, .080" guage.

Alumalite is a great choice for a sign that is easy to handle and easy to install. Although Alumalite may not have the thickness and panel strength of ARMOUR-Wood, it’s still an extremely reliable sign material. Alumalite is composed of corrugated plastic reinforced on both sides with rigid aluminum sign panels.

If you need a rigid, lightweight material for wall mounted signs, small post-mounted signs, or hanging signs, Dibond is great choice. Dibond is made of solid plastic reinforced on both sides with rigid aluminum panels. This combination of aluminum and plastic offers a sign material that is less rigid than Alumalite, yet substantially stiffer than a standard gauge metal sign.

ARMOUR-Wood has significantly greater panel strength over traditional sign materials because the outer, metal armor shell, is reinforced with a solid wooden core. This innovative combination of metal & wood makes Armour-Wood one of the strongest sign panels available. ARMOUR-Wood is absolutely perfect for large signage needs

What you need to Know About Outdoor Metal Signs

Is metal sign material really the best option for you?
How can you make sure you are making the right choice?
Knowing the key characteristics of metal signage will help you make the right decision.

Here are the key points to know before you make a final decision:

  • The most common type of metal used is aluminum sign material.
    Other metals available include Alumalite, Dibond, ARMOUR-Wood, steel, stainless steel, bronze, and brass.
  • Metal sign material is thin compared to thicker material like wood.
    However, you can get virtually any thickness or size metal you want.
  • Aluminum is the most lightweight sign material of all.
    When the correct thickness is matched to the overall size, it's quite sturdy.
  • Metal signage is rigid, yet flexible.
    In other words, metal can flex, as needed.
  • Steel metal signs are much stronger than aluminum.
    However, steel can rust over time — aluminum signage won't rust.
  • Standard durability is 3 years outdoors.
    The Premium option can extend the useful life to 6-10 years outdoors.
  • The metal surface is available in hundreds of different Pantone colors.
    Including brushed gold, mirror gold, brushed silver and mirror silver.
  • Metal can be lettered on one or both sides.
  • Outdoor Metal Signs are easy to install.
    (installation kits available).

Since real estate agents and contractors buy so many custom metal signs, one of the most common sizes is 18” height x 24” width. We also stock real estate sign frames which accommodate a 24” height x 18” width aluminum metal sign panel as well. Keep in mind though that metal sheeting can be easily cut to any “odd” size to meet your individual needs.

Odd size pricing just uses the next standard size up. Other popular sizes include: • 2’ height x 3’ width • 3’ height x 2’ width, and • 2’ height x 4’ width.

The sizes above can also fit into a sturdy angle iron step stake for a convenient and portable display. If you are in an area which has seasonally high winds, you should strongly consider upgrading the thickness of your custom metal signage for these larger size signs. The thicker the metal, the less likely the sign panel will buckle or be ripped from the bolts which attach the sign panel to the sign frame.

Increasing the thickness of your custom metal signs from a standard .040” to a medium duty .063” or extra heavy duty .080” gauge aluminum metal will enhance the durability of your custom metal signs. Generally, the larger the size metal sign you want, the thicker the metal material needs to be.

When buying custom metal signs to mount to a building, you can use .040" gauge aluminum for signs up to 2' x 4' in size. Technically, you can use .040" gauge aluminum for sizes all the way up to 4' x 10' provided you mount the metal flat against a wall with enough screws.

The larger the sign panel size though, the greater the tendency to bend. As a result, a large thin gauge metal sign can have a wavy or rippled appearance when installed, especially on a corrugated metal building. Therefore, when you want a bigger building sign, we recommend increasingly thicker gauges of aluminum with the optimum heavy duty thickness being .080" gauge aluminum.

The next thickness down is .063" medium duty thickness. On smaller size signs (up to 2' x 4') even a modest increase to .063" gauge aluminum substantially increases the stiffness, appearance, and rigidity of the metal sign panel.

The metal material itself will usually outlast the artwork on your sign. Our uncoated Economy Grade Signs are rated for at least 3 years outdoors while our Premium Grade Signs coated with an optically clear, UV Protective Lamination are rated for a minimum of 5-8 Years outdoors. Metal signs can last for decades indoors.

For exterior custom metal signs, you can use .040" for sizes up to 18" x 24".

Some people use this thinner .040" thickness all the way up in size to 2' x 3', but we don't recommend it. For sizes over 18" x 24", we recommend at least .063" thickness custom metal signs. And for larger hanging signs like 2' x 4', 3' x 3' or 3' x 4', .080" gauge metal works best for these heavy duty applications.

When in doubt, it’s better to go too thick than too thin because the heaviest .080" gauge metal we stock is still less than 1/8" thick.

While you can install larger aluminum metal signs (for example, 6', 8' or 10' long aluminum signs) on or between posts, you have better options to choose from:

ARMOUR-Wood is the strongest and most rigid exterior grade sign panel available with it’s dense, ½ inch thick solid wood core Alumalite (½” thickness) has almost the same sign panel strength as ARMOUR-Wood making it a popular choice for larger signs.

½” Alumalite is the 2nd strongest sign material Alumalite (¼” thickness) is still a strong, highly rigid sign background material and has the 3rd highest panel strength Dibond sign panels have 10 times more strength than .040” aluminum sheets.

Dibond is not quite as stiff as Alumalite, but is still considered a rigid sign material making it #4 in strength On a scale of 1 to 10, with “10” having the highest relative strength, here’s how each custom metal signs background material compares to one another:
