What Are Joist Hangers?

Joist hangers are metal brackets used to anchor horizontal joists to vertical framing elements like beams or ledgers. They provide a load-bearing cradle that holds the joist in place and transfers weight safely into the structure.

Our forged and decorative joist hangers are ideal for:

  • Decks and porches

  • Timber frame trusses

  • Ceiling beams

  • Rustic interiors or outdoor pavilions

What You’ll Need

Before installing your joist hangers, make sure you have:

  • The correct size joist hangers for your lumber

  • Structural screws or nails (check your local code)

  • A drill or hammer

  • A level or square

  • Pencil for marking

 Basic Installation Steps

  1. Mark the Joist Location
    Use a level or framing square to mark where the joist will attach to your ledger or beam.

  2. Hold the Joist Hanger in Place
    Align it with your markings and ensure it's flush with the surface.

  3. Attach One Side
    Secure one side of the hanger with structural fasteners. Use all the pre-punched holes for maximum strength.

  4. Insert the Joist
    Slide the joist into the hanger and check for fit and level.

  5. Secure the Other Side
    Fasten the opposite side of the hanger, making sure the joist is snug and flush.

  6. Toe-Nail or Add Through-Fasteners
    For additional strength, drive nails or screws through the sides into the joist itself.

Tips for Stronger Installs

  • Always use the right fasteners—not drywall screws or random nails. Structural-rated screws or joist hanger nails are essential.

  • If using decorative joist hangers, pair them with matching lag bolts or square head fasteners for visual impact.

  • For outdoor builds, use weather-resistant finishes like black powder coat or sealed raw iron.
