Sheet metal grain direction?
Bought a piece of 4x10-foot 20 ga. cold rolled sheet for a project. I will be cutting it up into 9-inch by 36-inch pieces and making some bends at the ends that have about a 1 1/2-inch radius to 90 degrees in some pieces and also to 180 degrees in other pieces.
I know that sheet metal can have "grain" but I can't find anything that will tell me if this 20 ga. c.r. sheet has it and if so, in what direction it runs. I presume that the grain would run lengthwise to the sheet. I also presume that that my bends would be easier if I cut the parts from the sheet so the grain ran parallel to the axis of the bend.
Any thoughts on this? Thanks!
