I need to replace the heat shields on my Gas Grill. My grill uses
individual "tents" over each of the 3 burners. The ones I am replacing
were porcelain coated but are now beginning to rust out.
I can get 3 porcelain coated heat plates for $43 or 3 stainless steel
plates for $19 - less than half the cost of porcelain coated.
Question 1: Will porcelain coated last twice as long as plain stainless
steel? Neither choice lists the gauge of the heat shields so I can't use
that to compare the two choices.
Question 2: I've seen some opinions that a rock plate is better for heat
distribution than heat shields. That makes sense. However, I assume I
will need a grate to hold the rock plate. A quick search showed some
galvanized steel rock grates. Can I expect these to rust out just like
the heat shields? Buying a rock grate and a rock plate is going to be
more expensive than the heat shields, but if they work better and last
longer, I wouldn't mind spending the extra money.
I have a Weber Genesis grill (barbeque) and it has these "tents" formed
out of plates of stainless steel bent at a 90 degree angle, with each
arm being about 2" wide. Weber calls them "flavorizer" bars.
I just rebuilt my 30 year or so sears gas grill. it uses lava rock.
the rock holding grate and grill plates were rotting away..
replaced now with 304 staninless which should out live me.. i had my
best friend do the stainless welding.... he did much of the rebuild in
i am giving serious thought to having him make the burner out of that
stainless its non magnetic.
my grill was my moms kept around for largely sentimental reasons, but
i think it wrks far better than the cheap chinese grills sold today
I had to go to Home Depot for some stuff so I wandered down the grill aisle.
I found an adjustable width porcelain cooking grate that was the perfect
length for my grill - $15.99. I found a bag of ceramic briquettes - $6.99.
I removed the rusted heat plates, sized the grate to fit on the heat
plate brackets and placed the briquettes on the grate.
I'm going to try it a few times and if I don't like the way it cooks,
I'll order some replacement heat shields and put it back the way it was.
While I was out I picked up a chicken which will go on the rotisserie
during the football games tomorrow. SWMBO bought some Jerk seasoning
that I've been wanting to try.
SWMBO and I finished a rotisserie chicken with Jerk seasoning. It came out
I won't know if the briquettes will help even out the heat or prevent flare
ups until I grill some sausage patties or burgers, but I'm glad I cleaned
all the grease and other crap out of the grill so I didn't have any
problems while doing the chicken.
Time to carve some pumpkins.
I have put my gas grill,parts in my gas ovens high temp cleaning
cycle, they come out looking like new:)
Although I put the alunimum body lower half and top in cleaning cycle
once, it came out looking great, but tad bit melted, lid didnt shut
right.. but I solved that:)
OK, so I've found one drawback of the briquettes vs. the heat shields/
The metal heat shields kept the gas at the bottom of the grill so that
lighting any one of the 3 burners with the igniter would eventually
light any other burner that had the gas turned on.
Now, since there is nothing to capture the gas, only the burner that
is lit with the igniter starts. Since a couple of my igniters are
intermittent, I either have to fix them or use a fire stick to light
any burner that doesn't light with the igniter.
I'd go with the stainless. Well, actually, I'd probably still use the
ones in there. Rust is not really a factor in how they perform. Clean
them as best you can. Soaking in an ammonia solution will get the
crud off, but do it outside and watch for the fumes.
Rust can inhibit the performance when they're so rusted that they aren't
solid anymore and the flames are coming up through them.
One is so rusted on one end that it barely reaches the bracket that holds
it up. If it drops down on top of the burner I'm sure it won't perform very
"Galvanized" means the steel has either been electroplated with zinc or
(better) dipped in molten zinc. The zinc prevents the steel form oxidizing
(rusting). You can easily melt zinc on a kitchen stove so I would expect it
to rapidly disappear on your grill leaving plain old steel. Steel rusts.

The melting point of zinc is almost 800 degrees F. Maybe you're thinking of
lead? Then again, I have a wimpy stove. (Zinc will certainly flake off over
multiple heat cycles though.)
Yes, but to get zinc "fumes" takes over 1600 F. It's a problem in welding but I
doubt it is on a grill.
However, I can say from experience that my homemade galvanized heat plates for
our grill hardly lasted long enough to have bothered...
