Customer Rating: Summary: Best grates available Comment: I upgraded the original porcelain grates on my Weber Silver B with these stainless steel grates about 6 years ago. I am very satisfied with these grates. Customer Rating: Summary: Great replacement part Comment: They work great, although I would have been OK with the original ceramic ones again. These look nice and bright and shiny clean until you use them the first time, and then they do not clean up to 'like new'. They are clean, but blackened sort of. The original black ceramic ones were easier to return to 'like new' after using. Customer Rating: Summary: Weber 7527 Stainless Steel Replacement Cooking Grates Comment: While use of these turns them just as black as the original manufacturer grates, they are not degrading [corroding] at all and I don't expect they will. Parts for these grills are pricey and sometimes buying new is barely a larger output of $$$. I thought these would extend the life of my current gas grill and I do like these grates very much. I would look for this feature on my next grill! Customer Rating: Summary: Weber Stainless Steel Cooking Grates Comment: They are fine. You can cook on them. As usual, Amazon did a great job in delivery. Customer Rating: Summary: Pappy Comment: The grates were shipped proptly, they arrived undamaged and are what I expected they should be.
