Compare the six HRB ranges for the specified bending or straightening task.
03
Review bar orientation, surrounding reinforcement and available power at the work level.
Bending and straightening must follow the project-approved requirements. A listed diameter range is not permission to rebend structural reinforcement.
Compare the listed ranges with your workpiece and installation requirements.
