What Are Joist Hangers And What Are They Used For

If you’re unfamiliar with certain hardware pieces, specific types of construction, woodworking, and more, you may have asked: What is a joist hanger and what are they used for? The following will be some information about the parts themselves and precisely what joist hangers are used for.

What Are Joist Hangers?

Joist hangers are used as supporting aids in the construction of residential structures to secure and support joists. They allow wooden beams and joists to be hung on other beams that are larger. To create a strong connection between a beam and joists, joist hangers are exclusively used above ceilings and underneath floors. They can also be used to support the platform of a deck, which is, in essence, a floor.

Joist hangers are used in order to avoid a specific problem: Warping and twisting can develop over time when joists directly rest on beams.

They're not allowed to deform, however, and their movement is restricted because joist hangers tightly secure the joists in place.

Joist Hangers – Installation

Over the sides and edge of a beam, joist hangers are installed. Using galvanized screws and nails, they are fixed in place.

To form a rigid connection, the attached connecting plates for these hangers are nailed into beams and joists. Joist hangers can be welded, in addition to being screwed and nailed, which would make their usage far more versatile. Over time, these are very cost-effective parts that have an easy installation process.

Joist Hangers vs. Weight

What kind of joist hangers should you install? You must take into consideration the weight and size of the joists.

  • 2 x 12 joist hangers: Minimum vertical 850-pound bearing capacity
  • 2 x 10 joist hanger: Minimum 605-pound capacity
  • 2 x 8 joist hangers: Minimum 540-pound capacity
  • 2 x 6 joist hangers: Minimum 305-pound capacity
