The problem with half inch Ply/OSB is it has limited screw holding ability, though you could also glue the Hardy Board to the OSB with polyurethane construction adhesive.How do you feel about 1/2 inch OSB with 1/4 hardy board over for grinding/welding area? Only problem is it comes in 3x5ft... Which doesn't seem to work well with 4x8 sheets for half a wall height. Other option might be sheet rock over 1/2... or just use the fire retardant paint over 3/4... decisions decisions.
Right now thinking 3/4 inch for most areas, unless 5/8 comes down significantly in price. If 5/8 were $20-25 i would go with it, but with 5/8 ag $31 and 3/4 at 34.50 a sheet, it seems like a no brainer to go with 3/4
Yeah at that price point ¾" is the way to go.
24 gauge galvanized sheet steel would make a great wall surface for a welding area. I haven't checked the prices lately but it used to be pretty reasonable.
