Joist Hanging Method

In modern buildings, metal joist hangers are often used to support the joists. Joist depths, widths and designs vary, so there is a wide range of hangers available to match. It is also an option to use joist hangers when renovating an old floor as these do not require large holes in walls and are straightforward to fix. Metal lateral joist straps are used to brace joists in position. One end of the strap is attached to the exterior wall, and the other end is attached to joists (either across or in line with them), to secure their position. Lateral joist straps are mainly used in new building projects. Shown here, the joists are attached to the wall using joist hangers, and the joists are braced with lateral restraint straps and metal herringbone struts.
