What is the recommended practice for bending rebar on-site?

The recommended practice for bending rebar on-site is to use a rebar bender. This tool is specifically designed to create precise and consistent bends in reinforcement bars while providing greater safety and efficiency. Using a rebar bender minimizes the risk of damaging the material or causing an injury, as it allows for controlled bending without excessive force.

Manual bending methods, such as using a hammer, can lead to inaccuracies in the angle and can also weaken the rebar due to the potential for over-stressing the metal. Utilizing a wrench may not provide the necessary leverage or control, resulting in imprecise bends and increased risk of injury. Heating the rebar before bending is not recommended, as it can alter the properties of the steel, reducing its strength and integrity. Thus, employing a rebar bender is the best practice for ensuring that rebar is bent safely and to the correct specifications on-site.
