Food for thought;
My cost for mild steel 3/4" x9 , 4'x8' is $42.00
My cost for stainless 3/4" x9 , 4'x 8' is around $160.00 ( goes up and down about $20.00, not sure why it fluctuates more than other products)
And my cost for 3/8" stainless round , in 12 ft lengths is $8.32 a piece.
The 3/8" round lets me build the grates to the exact length and depth that I want them to be, with no worries on wasting material on unusable drops, so cost wise, it's more effective than using the stainless 3/4" x 9, unless I was mass producing smokers and building all my grates the exact same size.even then, I would need to add the cost of 3/4" x 3/16" stainless steel angle to support the expanded, or weld it to mild steel angle ( no way ) .
Just food for thought,
