[Welcome] They get cut every time it is used, The more it is used the more it will have to be replaced. If the amperage is too high then the cuts in the grating will be deeper. It is a never ending cycle and in a way the grating could be considered a consumable of the plamsa table. [Welcome]

I guess I don't know what you mean by "a problem".

When I built my table, I made it so the grate slats could first be turned over, then replaced if and when needed. I've been using my table now for about 5 years and have only had to weld one grate slat back together when I was doing some Ace/Ox cutting and got a bit carried away and sliced it in half. I usually don't do as much damage with my plasma. I have turned over my slats in the middle part of the table where I do most of the cutting.

My slats are 1/8" X 1" strap set in 1 1/2" square tubing making up a square frame with "slits" made so they drop into the cuts and can be pulled up, moved around,flipped over or replaced as needed.

With the 1" depth of the slats, I haven't had a problem of cutting through them in general.

Hope that helps.

Need more information. How far apart are the slats? Will 1/8" wide stock fit? Can you purchase the stock "by the pound" in 20 foot sections or do you have to buy the stock from a Big Box store?

Okay -- so 11 gauge is 0.125 inches which is 1/8" so 1" flat should do. You need 80 feet or 4 - 20 foot lengths. My last purchase (about 6 months ago) the cost was about $8.75 a stick. So IF you can buy in 20 foot sections (have them cut 12 feet and 8 feet not in half for hauling -- or at least in something dividable by 4 feet) and not from a Box store, it should come out around $36.00.

Hope that helps.

Bob
