Stirrups

Stirrups are metal components used inside concrete beams and columns to hold reinforcing bars (rebar) in position and prevent them from moving or buckling under stress. Shaped like small loops or U-shapes, they encase the main reinforcement, providing lateral support and helping the structure withstand shear forces—those that can cause sliding or cracking. By maintaining the correct spacing and positioning of the rebar, stirrups ensure the concrete element maintains its strength and durability under loads, playing a critical role in the overall stability of reinforced concrete structures.
