0.1mm thick aluminimum metal panels with highly realistic and robust corrugations.  Panels can be layed on to each other just like the real versions.
The corrugations are spaced 2.5mm apart, perfect for representing larger asbestos corrugated panels in OO and HO gauges.  Also perfect for corrugated metal in 1/32 scale.
Pack of 10 large panels 100mm by 200mm. 
The corrugations run parallel to the shortest side.
