Aluminum Sign Blanks

When purchasing aluminum sign blanks, it is important to take into consideration the type of alloy being used. Some companies feature the thickness of their aluminum as a premium selling point, but without proper temperament or lower-grade of alloy the strength of the product may be compromised. Accordingly, STOP Signs and More uses 5052-H38 .063 inch thickness aluminum for signs 29 inches or under and .080-inch thick signs for aluminum 30 inches and over. Although our competitors may claim .080 thicknesses, these can be less-rigid and inferior if the quality of aluminum is lower i.e. 3003-H14 material. Read More

Why alloy is important:

To clarify, 3003 is a classification for aluminum alloy, while H14 is a measurement of hardness. 3003 is an alloy type that uses aluminum and manganese, and is one of the most common forms of aluminum alloy. This aluminum has a high degree of work-ability as it is able to be spun, deep drawn, brazed or welded. On the other hand, STOP Signs and More exclusively uses 5052 aluminum, which is the highest strength of all the forms of non-heat treatable grades of aluminum alloy. In addition to being stronger than other forms of alloy, it is also effectively resistant to corrosion from salt or water in marine environments. Applications for this form aluminum range from aircraft components and transportation parts to home appliances.
