JMC Steel Group’s history of delivering successful solutions reaches back more than 130 years. Decade after decade we have remained committed to our customers and end users. This focus has helped us stay strong for more than a century, and it has helped us grow larger than any other independent pipe and tube manufacturer on the continent.
The JMC Steel Group was founded as the John Maneely Company (JMC) in 1877. It started as a distributor of pipe, values and fittings in Philadelphia, Pa. and grew into one of the largest independent steel pipe and tube distributors on the East Coast of the U.S. JMC and its subsidiaries is the most trusted and comprehensive resource for structural and application-specific tubular steel products and solutions.
Today JMC Steel Group is the largest independent manufacturer of tubular products in North America. We produce more than 2.0 million tons of tubular products a year through our 12 Manufacturing facilities. With a thorough understanding of our customer’s businesses and markets, we enable wholesalers, distributors, fabricators, original equipment manufacturers, contractors and design/build engineering companies throughout North America to manage inventory, reduce supply chain costs, and meet their customer’s needs.
As proud as we are of our heritage, we are dedicated today to delivering customer needs tomorrow. We have the financial strength to continuously improve our facilities. We have the 1,800 people of JMC determined to give our customers quality products and exemplary service in the century ahead.
