ALUMINUM, 5" X 1/2" THICK, FLAT BAR,
HOMELAND SECURITY, DEPARTMENT OF.US COAST GUARD.CG-SEA-C23 · Response deadline: Mon, 26 Oct 2026
What the government is buying
The U.S. Coast Guard is procuring aluminum flat bar stock measuring 5 inches by 1/2 inch thick. This is a straightforward materials purchase under NAICS code 331318, which covers "Other Aluminum Rolling, Drawing and Extruding." This classification includes businesses that manufacture aluminum and aluminum alloy basic shapes such as sheet, plate, tube, and bar products.
The procurement falls under product service code 9530, used for metals in various forms. Aluminum flat bar in these dimensions is commonly used in marine and industrial applications—including ship repair, structural fabrication, and equipment manufacturing—consistent with Coast Guard operational needs. Coast Guard facilities at Curtis Bay, Maryland, serve as a major maintenance and logistics hub for the service's fleet in the Atlantic region.

Who can bid
This contract is reserved for small businesses certified under NAICS 331318. To qualify as small, a business must meet the size standard for this code—generally 1,000 employees for aluminum rolling, drawing, and extruding operations, though firms should verify current SBA size standards.
Bidders should be prepared to supply aluminum flat bar meeting the specified dimensional requirements. Firms do not need to be the original manufacturer to bid; distributors and traders may qualify if they meet small business size requirements and can furnish the required material. However, given the straightforward nature of this procurement and total small business set-aside, direct manufacturers and established metal suppliers with Coast Guard or federal contracting experience will be competitive.
How to put together a competitive bid
Verify material specifications. The solicitation specifies aluminum flat bar, 5" x 1/2" thick. Confirm whether the Coast Guard requires a particular aluminum alloy series (such as 6061-T6, common for structural applications, or another grade), temper, and applicable ASTM or military specifications. See the solicitation for complete specifications.
Confirm delivery requirements. Note the place of performance at Curtis Bay, Maryland. Determine whether delivery is direct to this facility, whether JIT (just-in-time) delivery applies, and what packaging and documentation standards are required for government acceptance.
Review pricing structure. Combined Synopsis/Solicitation notices typically require firm fixed pricing. Calculate material costs, freight to Curtis Bay, and any cutting or processing charges. Aluminum pricing fluctuates with LME market rates; consider whether your quote should account for price volatility over the contract period.
Ensure SAM.gov registration. Your business must be active in the System for Award Management with current representations and certifications, including small business status.
Prepare required documentation. Submit any mandatory technical data, material certifications, and past performance information requested. For metal supply contracts, mill test reports and certificates of conformance are commonly required.
