The bending allowance table is applicable to the corresponding material, material thickness and angle.

If the material thickness and angle in the table are not met, the following table can be used to calculate:

the bending allowance of the corresponding angle = material thickness * multiple of the corresponding angle 2.65-2.4

For example, the material thickness is 3, the material is ordinary steel, the bending angle is 95 degrees, and the corresponding bending coefficient = 3 * 1.6 = 4.8

The bending allowance table requires the non-right angle dimensions to be marked and measured as follows:
