Abstract
A hat channel, also called a furring channel, is a channel with a bottom horizontal web and two vertical flanges, as well as an outward lip that is fabricated by roll forming. When the channel is cut off at a specified length, the edge of the product will change due to the release of residual stress, and this change is generally called cut end deformation. The cut end deformation of channel steel was investigated via experiment and three-dimensional finite-element simulation. The effect of initial thickness on the cut end deformation of hat channel steel was studied. For hat channel steel, the deformations at the front end and back end increase when the sheet metal thickness increases. However, the influence of initial thickness on the cut end deformation of hat-shape channel steel is small.
