We are also very proud to be manufacturing and installing highway and specialty signs throughout New York State. Phelps Guide Rail, Inc. contracts to private individuals and commercial clients, such as municipalities and corporate facilities.We can accommodate everything from a stop sign in a campground to the signs and guide rails you see on the New York State Thruway. Quality product and service are driving factors for our employees, but so is safety.
