When you’re sourcing flanges, knowing where they come from matters. At PlateFlanges.com, we supply both domestic and imported flanges, depending on your project requirements, budget, and delivery timeline.

We’re transparent about origin, quality, and certification—so you get the right product, every time.

Domestic Flanges

Made in the USA, our domestic flanges are manufactured to meet or exceed industry standards, including:

  • ASME B16.5
  • ASTM A105 / A36 / A516
  • Full traceability and mill test reports (MTRs)

Why choose domestic?

  • Shorter lead times
  • U.S.-made steel
  • Buy American-compliant (for government or infrastructure projects)
  • Easier coordination with local suppliers and fabricators

Import Flanges

Our imported flanges come from vetted, high-volume manufacturers in countries like India, South Korea, Italy, and China. We only source from mills that meet:

  • ISO quality standards
  • Relevant ASTM, ASME, and EN specifications
  • Third-party inspection (upon request)

Why choose import?

  • Lower price point
  • Large volume availability
  • Suitable for commercial/industrial use where “Buy American” isn’t required

Quality First—No Matter the Source

Whether it’s a domestic or import flange, we don’t compromise on quality. All flanges are inspected, documented, and delivered to spec. If your job requires MTRs, NDE testing, or custom stamping, we’ll make sure it’s included—regardless of origin.

Common Questions

Can I mix domestic and import flanges in the same system?
Yes, as long as they meet the same dimensional and pressure standards. We can help verify compatibility.

Are import flanges lower quality?
Not necessarily. We work only with reputable mills that deliver consistent quality. The key is using the right flange in the right application.

Do you stock both?
Yes. We maintain inventory of both domestic and import flanges in standard sizes and materials.
