Steel Bar Bending Testing Machine

The steel bar bending testing machine applies bending force to steel bars through hydraulic or mechanical transmission, causing the specimen to deform at a set angle to detect surface cracks and plastic deformation capacity. It is used on construction sites and in quality inspection institutions to verify the cold bending performance of steel bars, ensuring that the material meets structural safety standards.
Selection
When selecting, consider the maximum bending diameter and stroke range to match the specifications of the tested steel bars. Check the accuracy of the bending angle and the stability of speed control. Verify the integrity of the protective devices. Confirm the compatibility of the equipment material stiffness with long-term usage loads. Pay attention to the clarity of the operation interface and the convenience of maintenance.
