Seabreeze Aluminum Culvert Inc.

Seabreeze Aluminum Culvert Inc., a veteran-owned small business manufacturer based in Winnie, Texas, supplies aluminum culverts, water control structures, and related piping components to the federal government as a prime contractor under Total Small Business set-asides. The company operates as a for-profit Subchapter S corporation and competes entirely in the small-business set-aside space, with 100% of its 124 recent federal awards designated for small-business procurement.

Seabreeze's capability footprint is highly specialized: the company fabricates and delivers aluminum corrugated metal pipe (18-inch and 60-inch diameter), aluminum slide gates and canal gates with manual or hand-crank operators, flashboard risers, weir boxes, anti-seep collars, and slotted aluminum stoplog boards for water management and habitat restoration at wildlife refuges. Representative work includes a $74,825 purchase order from the Fish and Wildlife Service for three water control structures at Tennessee National Wildlife Refuge in New Johnsonville (awarded July 29, 2026, performance through December 31, 2026), a $46,956 order for aluminum culverts and weir boxes at Atchafalaya National Wildlife Refuge in Louisiana (March 7, 2024), and a $42,383 order for aluminum culverts at La Grande Cote National Wildlife Refuge in Louisiana (June 1, 2023). Primary NAICS coding centers on Fabricated Pipe and Pipe Fitting Manufacturing (32 awards) with secondary activity in All Other Miscellaneous Fabricated Metal Product Manufacturing (13 awards) and Fabricated Structural Metal Manufacturing (12 awards); PSC coding aligns heavily to Pipe, Tube And Rigid Tubing (60 awards).

Customer concentration is extreme and durable. The Department of the Interior Fish and Wildlife Service accounts for 61% of awards (67 of 124) across its regions, with Fish and Wildlife Service Region 4 alone holding 46 awards worth $1 million combined potential value. The top five customers account for 61% of all awards; the top four (all DOI Fish and Wildlife Service offices) hold 52% of combined potential value across $1.48 million. The Department of Agriculture Forest Service R8-Southern Region represents the only diversified customer, with 7 awards and $65 thousand combined potential value. All federal work flows through direct purchase orders with no parent vehicles or IDV structures; awards are firm fixed-price and complete within single fiscal years or within calendar year-end windows. Activity has been episodic — one award in 2021, one in 2023, three in 2024, two in 2025, and four in 2026 — with low annual throughput but consistent renewal across refuges. Three awards (combined potential value $132 thousand) face ultimate completion inside the next twenty-four months, exposing the vendor to moderate recompete pressure. The company does not subcontract and operates entirely as a prime.
