corrugate

Form parallel grooves

To corrugate is to shape into parallel ridges and grooves, like the wavy pattern on cardboard or certain metal roofing.

The resulting texture adds strength and rigidity: corrugated steel, corrugated cardboard boxes.

A corrugated surface can also channel water or improve grip.

Brows corrugate when furrowed in concentration or worry.
