A housing for an aftertreatment system, the housing comprising:
- a plurality of single-layer, rectangular, exterior walls defining a generally rectangular interior cavity configured to enclose at least one aftertreatment component, at least one of the exterior walls comprising at least one corrugated panel having alternating grooves and ridges;
- and
- a frame formed by a plurality of beams, the frame supporting the plurality of exterior walls,
- wherein each alternating ridge of the at least one corrugated panel includes a raised wall, the raised wall including one or more extension portions that extend in opposite directions from each other, each said extension portion overlapping and contacting a corresponding one of the plurality of beams,
- wherein at least one of the extension portions overlaps and contacts at least two sides of one of the beams of the plurality of beams of the frame,
- wherein said at least one extension portion includes a bent edge that wraps around and engages said one of the beams, and
- wherein the raised wall extends from one side of the exterior wall to the other side of the exterior wall opposite the one side.
