What Maruichi American Corporation does

Maruichi American Corporation (MAC) is a U.S. steel tube manufacturer headquartered at 11529 Greenstone Ave, Santa Fe Springs, California. Established in 1978 and in production since 1980, the company manufactures cold-formed welded carbon steel tubing in round, square, and rectangular shapes across two core product lines: ASTM A500 structural tubing (Grades B and C) for hollow structural sections used in construction frameworks, and ASTM A513 mechanical tubing used in racks, fences, furniture, ornamental fencing, and decorative handrails. Production capacity has been expanded incrementally over time — a 1.5" mill (1985), a 2" mill (1991), and a 12" mill with #2 slitter (1998) — enabling current size ranges up to 10x10 square and 12x8 rectangular configurations.

The business is a wholly-owned subsidiary of Maruichi Steel Tube Ltd., a Tokyo Stock Exchange-listed Japanese parent whose origins in steel tube production date to 1935. MAC operates within a broader North American group that includes Leavitt Tube (acquired 2008, Illinois), Maruichi Oregon Steel Tube / MOST (2015, Portland), and MARUICHIMEX S.A. de C.V. (2012, Mexico). Revenue mechanics are simple: industrial and construction customers purchase tubing via direct sales (quote-based pricing, no public price list) from a named inside/outside sales team; a credit application process supports extended payment terms for qualified accounts. The company does not publish revenue and is privately held; ISO 9001:2015 certification (since December 2018) and an Environmental Product Declaration are the principal published credentials. Industry association memberships (MSCI, Steel Tube Institute, Committee on Pipe and Tube Imports) round out the commercial positioning.
