Manual straightening

Fix the steel bar, then cover the bend of the steel bar with steel pipe and straighten it by hand.

The traditional methods of straightening steel bars at pile head, such as manual straightening and fire heating, are very inconvenient to construct and may damage the performance of steel bars, especially for large-diameter steel bars above φ28, which are extremely difficult, slow in manual straightening, low in cost and low in efficiency.

It is difficult to meet the requirements of supervision by straightening the fire wrench.

It is recommended to use a hand-held wire rod head straightener.
