Insteel Industries Inc
insteel.comInsteel Industries (NYSE: IIIN) is a U.S. steel manufacturing company that produces steel wire reinforcing products for concrete construction applications. It generates revenue by selling two product lines, prestressed concrete strand (PC strand) and welded wire reinforcement (WWR), on a transactional basis to customers in the construction industry. Insteel is the largest domestic manufacturer of steel wire reinforcing products by its own description in the FY2025 10-K filed October 23, 2025. The business is capital-intensive, relies on hot-rolled carbon steel wire rod as its primary raw material, and operates with a $100.0 million revolving credit facility. Demand is seasonal, peaking in the third and fourth fiscal quarters when construction activity is highest, and cyclical, tied to overall nonresidential and residential construction volumes. CEO H.O. Woltz III serves as President, Chief Executive Officer, and Chairman of the Board, with CFO Scot R. Jafroodi as Vice President, CFO, and Treasurer.
Products & Services
PC strand: high-strength, seven-wire strand used to reinforce precast and prestressed concrete elements including bridges, parking decks, and buildings. WWR: welded wire reinforcement used in nonresidential and residential concrete construction. Engineered structural mesh (ESM) is a developing product category within the WWR line. All products are manufactured from hot-rolled carbon steel wire rod.
Revenue Model
Transactional product sales of PC strand and WWR to construction industry customers. Selling prices reflect raw material input costs, primarily hot-rolled carbon steel wire rod, and are subject to competitive pricing pressure. No subscription or recurring-fee component is disclosed in the FY2025 10-K.
Customers & Markets
Customers operate in the concrete construction industry, spanning nonresidential and residential construction. End use applications include bridges, parking decks, buildings, and other concrete structures. Backlog is minimal due to short customer lead times, per the FY2025 10-K. No individual customer concentration percentages are disclosed in the provided excerpts.
Geographic Exposure
Operations are entirely domestic, focused on the U.S. concrete construction market. Import competition is a factor in certain PC strand and standard welded wire reinforcement segments not covered by Buy America requirements.
