How we make our stop signs
We make our STOP signs with the highest quality 3M reflective sheeting and 3M inks. Our 18, 24, 30 and 36-inch STOP Signs are made using .080 gauge heavy duty 5052-H38 aluminum. We then apply 3M Engineer Grade Prismatic sheeting, 3M High-Intensity Prismatic sheeting, or 3M Diamond Grade sheeting. Individuals, Property Managers and Private Businesses can now buy direct from our factory, getting the same great signs we have been selling to States and municipalities for decades!
