No its seemed just like the original. The original one twisted/warped about 7/8ths an inch and lifted the drip pan. The replacement is warped about 1/2 inch so far after a dozen cooks or so. Now with the modified one I will see what happens
I got a new one exchanged for warranty and its has a slight warpage now, but not as bad. So I took my original one and found some SS tubing around work and brought it to my buddies shop. It is fixed now!!!!
It seems thick enough for me since a big pan or plate is sitting on it while I'm cooking, as for the corners I used a cutting wheel on my angle grinder to round the corners, cut to size and smooth all of the edges.
On my TB340, it was warped about 1 inch. I did not contact RecTeq until it warped too much and lifted the drain pan. They replaced it under warranty. The new one has a little warping also but not as bad, So I will keep an eye on it.
