cross-members

Horizontal frame pieces

Cross-members are structural components that run perpendicular to the main frame or longitudinal members of a vehicle, building, or other construction.

In automotive contexts, cross-members connect the two sides of a chassis, providing rigidity and mounting points for engines, transmissions, or suspension components: The mechanic replaced the rusted front cross-member.

In carpentry and steel framing, cross-members brace horizontal spans against twisting or collapse.
