The Best Reflective Material For A Stop Sign

October 12, 2017

Stop signs weren’t always something you would see on roadways. In fact, when cars first started to make their way out on the roadways, things became quite chaotic. Between cars, bicycles and even horses on the roads you can only imagine how awful it was to drive around with no stop signs! Not to mention how many accidents there must have been without the ability to warn drivers of oncoming traffic. These days, we see stop signs everywhere. From side streets, to main streets and everywhere else in between.

But, how are stop signs made? Is there a specific material you should use for a stop sign? Or can you use or buy any material available? What materials are the best to use on stop signs and other signage?

Different types of reflective sheets are used for different kinds of road signs . For example, Engineer Grade Reflective Sheeting ASTM D4956 Type 1 is commonly used for non-critical signs such as parking signs or turning signs. This can also be used for reflective stickers as well as decals.

On the other hand High Intensity Prismatic (HIP) Sheeting are best used as a non-metallized reflective sheet for road and traffic signs, as well as barricades, cones and barrels.

But what is considered the best type of reflective material for a stop sign? According to legislative guidelines, the best material is called Diamond Grade Reflective Sheeting (DG3). This type of material meets the standards for ASTM Type XI standard. At the present time, all “critical” signs are required to use this type of reflective sheeting. Chances are in the future, all non-critical signs will be required to use this type of material as well because of how functional and efficient it is. This type of material is not only used for stop signs either but also speed limit signs. This, as well as the other two reflective materials mentioned above use a diamond grading sheet that has pressure sensitive adhesive. The adhesive is usually applied to a stop sign made from anodized or anodized aluminum and applied with either a hand roller or an applicator.

This type of stop sign was specifically created, designed and engineered with newer headlight models in mind. This type of reflective sheeting is also good for older drivers who need extra luminosity while driving, and truck drivers who need to be able to see signs from a further distance.

You can also get a premium graffiti overlay on these reflective stop signs which protects the signs from spray paint, markers, and more. The only thing you need to easily clean spray paint off is warm water and a mild cleaning product. This shows how stop signs and the way they are made have significantly changed for the better over the years.
