For over 50 years, Major Metals Company has specialized in manufacturing high-quality ERW steel tubing — with core offerings in A500 structural tubing and A513 mechanical tubing. Continuous reinvestment in facilities and equipment, combined with diverse material sourcing, has driven our growth in an extremely cyclical industry.
Major Metals Company was incorporated in Ohio in October 1973 by founder Jack Mason — consolidating his trading activities in steel products and contract manufacturing into a single, family-run operation.
In the mid-1980s, Jack began stepping back from day-to-day operations. His retirement was finalized through a buyout agreement with his son, Jeff Mason, dated January 1, 1985.
Sam Mason, Jack’s grandson, joined the company in June 2014 after graduating from Xavier University with a degree in Finance. Today he serves as President and COO — the third generation of the Mason family to lead Major Metals.
Fifty years in, the formula hasn’t changed: leverage diverse material sources, reinvest relentlessly in equipment and facilities, and be the supplier a customer can call when nobody else can hit the date.
Every expansion, every mill, every new line — chosen to make the next order better than the last.

Two welded steel tube mills purchased in June. In December, an 8,000 sq ft building on Kochheiser Road in Mansfield is acquired as the new home of operations.
The 3.125″ OD Yoder tube mill is operational by August — the start of in-house ERW tube production.
12,000 sq ft expansion in 1996 followed by another 4,000 sq ft in 1998 to support growing production.
Major expansion adds finished goods storage and additional manufacturing equipment.
24,000 sq ft overhead-crane building completed. 72″ × .250″ × 60,000 lb steel coil slitter installed — closing the loop from master coil to finished tube.
2″ OD T&H Lemont tube mill operational in 2010. 15,000 sq ft slitter building expansion follows in 2011.
Sam Mason joins as President and COO after graduating from Xavier University. The same year, Major Metals acquires tubing operation assets in Kings Mountain, NC — including a fourth tube mill (3.125″ Yoder), Haven re-cut machine, and BEWO automatic tube cutter.
Free-standing expansion completed. North Carolina assets relocated to Mansfield and integrated into the main facility.
Another 48,000 sq ft expansion comes online alongside a new 3.5″ Rafter tube mill — expanding capacity into the outdoor metal building market.
32,000 sq ft expansion in 2024 paves the way for the 2025 commissioning of a new Seuthe FCF500 5SQ .250″ structural tube mill, targeting A500 HSS and solar markets.
Five active tube mills, three active re-cut machines, a full-capacity coil slitter, and a growing range of structural and mechanical tubing capabilities — all under one roof in Mansfield, Ohio.
