Maruichi Oregon Steel Tube

What Maruichi Oregon Steel Tube does

Maruichi Oregon Steel Tube, LLC (MOST) is a Portland, Oregon-based manufacturer of hollow structural sections (HSS), producing cold-formed welded and seamless carbon steel structural tubing in square and rectangular shapes. The company operates a single Portland facility (8735 N Harborgate Street) with annual production capacity of up to 150,000 tons, marketed exclusively across the Pacific Northwest region (western United States, British Columbia, and Alberta). MOST was founded in 2015 when its Japanese parent Maruichi Steel Tube Ltd. (Osaka, Japan; founded 1926, Tokyo/Osaka Stock Exchange listed since 1964) acquired the Evraz Oregon Steel Structural Tubing plant on March 5, 2015, marking the parent's entry into North American production.

The product portfolio is narrowly defined around two specification families: ASTM A500 cold-formed welded carbon steel structural tubing (Grades B and C for US markets) and CSA G40.21 structural tubing (primarily 350W grade, with capability for higher-strength 480W and corrosion-resistant AT grades for Canadian markets). Available dimensions span 2.5"-10" square, 3"x2"-12"x8" rectangular, lengths of 20'-70', and gauges from 0.120"-0.500". The business is ISO 9001 certified, which is a meaningful procurement prerequisite in the construction supply chain. End applications include structural support for buildings, bridges, highways, and industrial, transport, and agricultural equipment.

Revenue is generated through direct B2B sales of physical steel tubing products to construction contractors, steel fabricators, and industrial equipment manufacturers in the Pacific Northwest. The go-to-market relies on a small in-house sales team (Sales Manager and Inside Sales Representative) supported by regional account management and three industry association memberships (PNSFA, MSCI, STI). Pricing is quote-based and transaction-by-transaction; no public pricing, e-commerce, or volume-tier models are disclosed. The company is privately held as a wholly-owned subsidiary of Maruichi Steel Tube Ltd., with no external equity or debt funding events on record.

Scale indicators4 records

Recent moves6 records

Expansion highlights4 records

Broad incumbents

• Atlas Tube (Zekelman Industries): Atlas Tube is a leading North American producer of hollow structural sections (HSS) and steel tubing. It directly competes with MOST on ASTM A500 HSS products but operates at much broader geographic scale across the US and Canada.
• Nucor Corporation: Nucor is the largest US steel producer with a dedicated structural and tubing division producing HSS, pipe, and structural steel. It is a broad incumbent with overlapping HSS product lines but vastly larger scale and broader product portfolio than MOST.
• Gerdau Ameristeel: Gerdau operates extensive North American structural steel and rebar operations, including HSS production. It competes with MOST on structural steel products and serves Western US markets through distribution.
• Tenaris (TenarisBay City / US operations): Tenaris is a global steel pipe and tube producer with US seamless pipe operations. While focused on OCTG and line pipe, its tubular manufacturing capabilities and North American footprint make it a broad incumbent comparable to MOST.
• Vallourec Star (formerly V&M Star): Vallourec operates seamless pipe and tube production in Youngstown, Ohio and other US facilities, with some HSS overlap. It is a broad incumbent in the steel tubular products market adjacent to MOST's structural tubing category.
• Steel Dynamics (Structural & Rail Division): Steel Dynamics manufactures structural steel products including HSS through its fabrication operations. As a top-tier US steelmaker, it competes with MOST on structural steel supply to Western US construction markets.

Emerging players

• Ternium (Ternium Mexico / US operations): Ternium produces structural steel products and tubular goods for North American markets, with growing presence in US West Coast distribution. It is an emerging regional competitor overlapping MOST's structural steel product category.

Direct peers

• Maruichi Steel Tube Ltd. (Parent / Japan operations): Maruichi Steel Tube Ltd. is MOST's Japanese parent and operates the world's largest steel tube production network. Its domestic Japanese facilities directly mirror MOST's HSS manufacturing capabilities and serve as the corporate standard for product and process.
• EVRAZ North America: EVRAZ was the previous owner of MOST's Portland plant before Maruichi's 2015 acquisition and operates other North American steel tube and pipe facilities. It remains a direct comparable in product category (structural steel tubing) and customer base.
• Maruichi Leavitt Pipe & Tube: Maruichi Leavitt Pipe & Tube is a sister subsidiary under the same Maruichi group, producing steel tubing in the US Midwest. As a sibling company with shared product lines and corporate ownership, it is a direct functional peer to MOST.
