A length of steel or iron bent at a right angle along its long dimension, used as a support or structural framework.
Floating Upper Angle Iron Shear Knife
A unique style of angle iron shear knife where the upper knife actually floats or rotates to center itself in the gullet of an angle iron section. This feature provides the benefits of minimal distortion and slug free shearing. In other words, no material is lost during the shearing operation. Some ironworker angle iron shears actually remove a "slug" from the material being sheared. This slug is waste (scrap) and thus increases operating costs.
