Our Commercial Grade 4″ Grey Granite Curbing is an excellent choice for any commercial or residential project that wants to raise the standard, life and look of your curbs. Concrete curbs are ugly and they don’t last very long. Granite is forever and it gives your project a look above the rest. A high end feel and it does not degrade under the tough winter conditions of the Northeast. Our Grey Granite is unphased by freeze thaw cycles and salt used for ice control. Going with 4″ Commercial Curbing is a lot more economical than you realize. We have you covered with straight, standard radius inventory. For custom orders send us your plans and we will produce the custom lengths to fit your project.
