Looking for a particular kind of plasticard

I'm looking for a particular kind of plasticard sheet.

It has raised, straight, thin ridges on it.  They need be quite close together.  I've looked online but can't really find anything like it but I'm sure I've seen it.  I seem to remember a brand name along the lines of "AMRI" or something similar?  They are a line for use with architectural modelling.  It has various scaled cars, people, etc., as well in their range. It isn't Plastruct.

AMRI seems to be the correct name:

Thanks, but without some better descriptions/images I fear I would choose the wrong one.  I think this bears more thought/research.

Evergreen Scale Models .040(1mm) corrugated sheets come in a variety of spacings, the
smallest has a .030(.75mm) groove spacing with .010(.25mm) width ribs.

That looks more hopeful and closer matches the description of what I need.  Thanks, Jon.

You will have more luck finding these in the model railroad section or shops than regular model shops & such.

Plastruct has several variations of corrugated plastics and scales.
