What is a beam hanger?
A beam hanger (also known as a joist hanger) is a metal connecting device used to support timber beams and connect them to other structural elements such as main beams, walls, or columns. It is one of the most widely used connectors in timber construction, providing a reliable, quick, and strong connection without the need for complex timber joinery.
Types of beam hangers
Several types of beam hangers exist, each designed for a specific application:
- Face-fix hangers: the beam is dropped in from above and rests on the bottom of the hanger profile
- Top-fix hangers: the hanger is mounted on top of the supporting member, with the beam suspended below
- Concealed hangers: recessed into the timber so they are invisible after installation, commonly used for exposed beam work
- Adjustable hangers: allow height adjustment for levelling the construction
Hangers are typically manufactured from galvanised steel and are fixed using wood screws, connector nails, or bolts.
Sizing and selection
Choosing the correct type and size of beam hanger depends on several factors:
- The dimensions of the beam (width and depth)
- The load the connection must carry (shear force)
- The timber species (softwood, hardwood, glulam)
- The direction of loading (vertical, angled)
Manufacturers provide load tables and calculation guides to assist in selecting the appropriate hanger. When in doubt, a structural engineer should be consulted.
Application
Beam hangers are widely used across construction: from house building and extensions to garden structures such as pergolas and carports. They are particularly popular in DIY projects due to their straightforward installation.
In professional timber-frame construction, beam hangers are an essential component of the structural system. They enable rapid assembly on site and ensure consistent connection quality. Building regulations typically require that hangers are installed according to manufacturer specifications, with the correct number and type of fixings.
