Topic: Confirmation on spreader plate sizing
I think I already know the answer to this question. But to be safe. Spreader plates.
When building plinth boxes, if you bend the spreader plate so that it welds to both the floor and up the sill, all of that surface area counts correct? Meaning if my plate has 6"x3" on the floor, and then 6"x5" up the sill I have a total spreader plate area of 48sqin. Then you obviously add the rest of the material to build that into a box.
I believe this is a correct statement, but I'd hate to show up and get called out because only 18sqin counted.
