Sheet Metal Stiffening Ribs

Apr 13 2017 sheet metal brackets with stiffening ribs.

Sheet metal stiffening ribs.

This can be fixed by adding stiffening ribs that are much stiffer and act as load paths. Design guidelines for stiffening ribs according to the association for rotational molding arm the depth of a rib should be at least four times the nominal wall thickness. Each groove bead or line will compound the strength and can also add a design to the panel. Pressing grooves ribs or designs into a piece of sheet metal will greatly increase the strength.

If the plate is compressed in plane the stiffeners will significantly increase the buckling load. A method of forming intersecting stiffener ribs in a flat sheet metal panel so as to rigidify the panel and prevent it from flexing along mutually perpendicular axes by cutting one or more slit. The stretched metal in those areas will hold tension in the panel and give it structural rigidity. Sheet metal with structural grooved seams.

The stiffening rib is added to the bracket at the bending stage by separating the bottom bend blocks and inserting a metal strip in the gap which then forms a rib at the same time as the angle bend.
