About AGCP
The American Granite Curb Producers (AGCP), a non-profit organization, was formed in 1990 as an educational platform for consumers of their products in regards to the performance and costs of granite curbing vs. concrete. The members of the organization pooled their vast knowledge of granite and curb construction in order to inform their product consumers of the long-term benefits of granite curb, as well as to assist with designing better, more economical curbing products.
The AGCP work closely with architects, developers, engineers and specification writers to ensure they get quality curb on time, every time. Our members have made substantial investments in production facilities and manufacturing equipment to ensure that our customers receive a consistent product with superior quality at an affordable price.
Each of our members is committed to the highest standards of ethical business practices and to the highest quality of materials and workmanship, placing our respective and collective expertise at your service. Below is a brief description of our members:
