Definition & Meaning of "joist hanger"

What is a "joist hanger"?

A joist hanger is a metal bracket used to support and secure joists, which are horizontal beams that help hold up floors or ceilings in a building. Typically made from coated steel or other durable materials, joist hangers are attached to beams or walls to provide a stable connection for the ends of joists. This helps to ensure that the joists remain properly aligned and securely in place, preventing movement or sagging. Joist hangers are commonly used in both residential and commercial construction to enhance the structural integrity and safety of flooring systems.
