There are three choices available for replacement Weber Genesis Silver grates. The grates cost between $40 and $80 depending upon which grill and which style you go with. My personal favorite grates are cast iron but I wouldn’t recommend them for everyone.
Porcelain Enameled Steel Grates
The porcelain enameled steel grates are the most affordable of the three options. The version of these grates for the Silver B and Silver C are perfectly fine. I think the version of this grate made for the Silver A is completely hideous.
The porcelain enameled steel grates for the Silver B and C are simple straight bars that let you put proper grill marks on a steak or pork chops. Compare this to what is available for the Silver A.
What in the heck were they thinking with this grate? Is it functional…yes. Can you put a diamond cross hatch on a New York strip…nope. Proper grill marks might not be important to you but to me they are an essential part of grilling.
Stainless Steel Grill Grates
You can’t go wrong with stainless steel. The design of the stainless steel grates are the same for the Silver A, B and C grills. The grate is made of straight bars of stainless steel. This grate works perfectly fine but don’t be surprised when they don’t look like the stainless steel grates on the current Genesis grills which are made of 7 mm round bars.
Cast Iron Grates
I have mixed opinions about the cast iron grates for the Genesis Silver. One thing I am certain about is that it makes me happy to know that I have cast iron in my grill. No logical reason there…I just really like the thought of cast iron.
If you properly preheat your Silver on High for at least 15 minutes then you can get some great grill marks. The problem is that most folks will only preheat for about 5 minutes and they will be disappointed with the results.
In 2000 and 2001 the cast iron grates available for the Silvers were raw cast iron that you seasoned with vegetable shortening. This is what I have on my Genesis Silver A. I can attest that maintaining these grates is a giant pain in the neck. If you currently have these grates then here are the instruction on how to keep them properly seasoned.
Weber received so many complaints about these grates rusting that in 2002 they started adding a clear porcelain enameling. The clear enameling lets the grates look exactly like seasoned cast iron while preventing the cast iron from rusting.
The cast iron grates I have linked to in the parts list are the porcelain enameled versions.
