[Cook]

Any one have experiences with cuts on Hot Rolled plate vs cold rolled plate and plasma cutting . I’m interested if so .

Hot rolled or cold rolled sheet metal

Are there any recommendations I’m cutting a lot of 16 and 14 gauge sheet metal. Does anyone have a recommendation whether to use hot or cold rolled steel.

Material Choices

And I will go first. I am thinking Hot Roll Steel, 1/8 in (11 ga) for a sign that I want to age and show rust. Am I on the right path? Is Hot roll a good choice for cutting? It is significantly less expensive than CR.

Metal for projects...what do you use?

There have been some threads on metal choice…but I want to condense the information a bit. poll what about the gauge of metal most used for signs poll

that is just a start

Thanks toolboy

No matter hot or cold rolled always clean a spot for the work/ground clamp on the sheet. Do not clamp on the table or slats.

Mechanic416 is so right on that…I want to find the video or pictures of when someone posted…not here…of what happened to someone who clamped to the slats…
the slats are not always good contact with the metal due to deposits and buildup…when they clamped to the slat it created arcing between the slats and the metal…the arcing started to pit and eat away at the metal in several places.

Aluminum and Stainless are the worst for the arcing between the slats and metal if you have the work/ground clamp on the table or slats.
