The Gizmo Bend Curve deformer may be useful. However in this situation since it appears as if you’re just duplicating a very simple mesh, it may be easier to simply create one mesh in the proper form to begin with then duplicate it.
The regular Gizmo soft falloff feature could be used to quickly curl a mesh. If the Focal Shift value for the Transpose brush is set to values greater than -100, then the operations with the Gizmo will only partially deform a mesh. You could use this with the rotate function to curl a mesh.
A brand new tool available to ZBrush subscribers today is the new “Anchors” brush which allows you to very quickly set two simple points and deform a mesh in screen space by rotating one around the other. This could be used with a soft-edged mask to quickly curl a mesh in the viewport.
