I am wrapping a porch beam with white steel fascia board cover. The height of the space I need to cover is about an inch less than what the fascia board cover is. So I need to basically cut an inch off the entire length of steel for this beam. It's about 28 linear feet of material.
I am afraid using tin snips would crinkle the material. I am thinking of a cutting disc on an angle grinder but that's going to make a heck of a mess and brings in potential for not getting a straight cut. A skill saw with a carbon blade would mar the paint in a heart beat, it seems like it's so easy to scratch. Any other ideas I have not considered?
