The Appian Name

Synonymous With
Engineering Excellence

The name Appian is synonymous with engineering excellence. Claudius Appius, the Roman official credited with constructing the Roman highway system, enabled the Romans to conquer the world. The superior quality of these roads allowed Roman generals to dispatch their legions to the outskirts of the empire quickly and efficiently — and provided easy access to trading ports throughout the world.

The slogan “All roads lead to Rome” was literally true thanks to the genius of this ancient engineer. Many of these roads still survive today after 2,300 years, and the Appian Way which bears his name is still used by travelers.

At Appian Manufacturing Corporation, we are proud to bear such an excellent name as we present excellence to the construction and industrial markets of our time.
