PRG is dedicated to excellence in roll services for North America's industrial roll users
For more than 35 years, PRG has been the North American industry's quality choice for high-accuracy grinding of
rolls, drums, cylinders and shafts of virtually all weights, sizes and compositions.
At PRG, roll grinding is our primary business. It is not a side-line service. For this reason, our exclusive
commitment to roll grinding has won the trust of progressive roll users and original equipment manufacturers.
PRG continues to grow as a result of this ongoing working trust and commitment to the pursuit of perfection in
every grinding opportunity.
PRG's four plants
Our facilities located in Allentown, Pa., Carrollton, Ga., Lewisport, Ky.; and Texarkana, Ark., were constructed
from the ground up expressly for the purpose of roll grinding. The million-pound foundations for our grinders and
lathes are built with shock-absorbing springs to provide the optimum vibration-free environment for precision roll
finishing.
PRG's grinding technology
Each plant is equipped with Waldrich-Siegen grinders, recognized as the finest in the industry. With PRG's
grinding technology, a 120-ton roll of metal or granite, or a 60-ft. ship propeller shaft can be ground to
tolerances as fine as 20 millionths of an inch — that's over 75 times finer than the width of a human
hair.
PRG's Craftspeople
Every grinding team member at PRG's plants has been the recipient of stringent training — either as an
apprentice through our apprenticeship program or as a new hire whose experience has been refined to meet our
tough internal quality standards. Continuing education courses and training programs are offered annually to
ensure that every grinding team member is familiar with the latest trends and practices, guaranteeing that we
have the most experienced and dedicated roll grinding specialists in the world.
