Product Description

Corrugated Sheet Metal: The corrugations are described in terms of pitch (the distance between two crests) and depth (the height from the top of a crest to the bottom of a trough). Pitches have ranged from 25 mm (1 inch) to 125 mm (5 inches). It was once common for CGI used for vertical walls to have a shorter pitch and depth than roofing CGI. This shorter pitched material was sometimes called "rippled" instead of "corrugated". However nowadays, nearly all CGI produced has the same pitch of 3 inches (76 mm).


Version 1 of my corrugated dies had a pitch of 1.087 mm and a depth of 0.575 mm. Full-size this would be 3.7" and the depth 2". When I tested the dies using aluminum foil the metal sprang back about half the depth. These two dies .. one has a corrugation depth 1-1/2 X Version 1 of 0.863 and the other has a corrugation depth 2 X Version 1 or 1,15 ,, the purpose is to see which one produces the best scale corruaged iron sheet using aluminum foil.
