I do know they are regional items but that's strange just the same.
Actually, welding in the board caps came from the southern builders of trailers. it was always faster to weld something than bolt it in. They would just lay the lumber on the deck, take a big pry bar and squeeze it to one side or the other to eliminate any big gaps and drop some cut chunks of steel in to hold it snug from side to side. Then, c-clamp the angles on both ends and weld them down. zing-pop-pow.. floor done.
The bolted in floor thing started a little further north and bolting down the board end caps meant that if a plank needed replaced, you just unbolted the end caps and that plank, put a new one in, drilled, bolted and you were done.
The notched end cap was mostly an eastern us thing i think. Regardless, after about four or five years, the bolts were rusted and it was time to get the grinder out for any type of plank replacement. If anyone wants to know the REAL trick for getting a super tight floor AND using only 10" boards (which are always stronger) pop a reply here.
