Abstract
A structural member for a structural frame comprises a substantially planar wall and two opposing irregular-shaped sidewalls integral with the planar wall. Each irregular-shaped sidewall has a corrugation. The member has two free ends where the portion adjacent each free end is flattened. The corrugated sidewalls are adapted to fold upon themselves when a force is applied to an area of the member. The flattened portion is adapted to be secured by fastening means to components of the structural frame. The width of the flattened portion is substantially the same as the nominal width of the member. The structural member has a neat appearance at its flattened portion.

In a ladder frame, a structural member of malleable metal comprising a substantially planar wall and two opposing irregular-shaped sidewalls which are integral with substantially parallel edges of said substantially planar wall, each of said irregular-shaped sidewalls having a corrugation therein which extends along the length of each sidewall, said member having two free ends, said corrugation adapting each sidewall to fold upon itself when a force is applied to an area of said member to provide a flattened portion on said member, the flattened portion being adapted to be secure by fastening means to a component of said ladder frame, the width of the flattened portion being substantially the same as the nominal width of said member.
