Straightening plate

A straightening plate is a flat steel plate on which steel structures are straightened two-dimensionally in metalworking workshops . Straightening plates are available in sizes from less than 1 m² up to several 100 m².

Two-dimensional workpieces and components made of steel such as railings , steel frames or steel constructions are distorted during manufacture due to thermal or mechanical processes such as welding , forging or rolling . In order to bring warped components back into the correct shape, they are placed on the straightening plate after completion and straightened with hammer blows , pressing , by bracing or local heating.

Straightening plates have bores for receiving mandrels with which a workpiece can be clamped. To facilitate the control measurements during the straightening process, straightening plates are often provided with a cross grid of ground lines with a line spacing of 100 mm.
