Cross-bracing is the addition of diagonal reinforcement applied to any form of framework.

Strips of wood, metal or other material may be used, which are crossed to form an X shape and help stiffen a frame by preventing any lateral movement.

In residential properties with timber floor joists, cross bracing can be inserted between the joists to prevent them from moving, eliminating squeaking and deflection, and increasing overall stability in the floor system.

Cross-bracing can also be added to ceiling joists, especially in larger properties. 

Cross braces in such applications is typically constructed from wood strips, although metal cross bracing ties are sometimes used, as well. Bracing strips are nailed from the top of one floor joist to the bottom of the next joist, and vice versa, forming an X.

Cross braces may be installed during the construction process or added to older homes. 

Cross-bracing may also be inserted in the roof structure to keep roof trusses in alignment.

In timber and steel-framed buildings cross-bracing is used to hold the frames square.
