Hongso Replacement Grill Grates & Flavorizer Bars for Weber Genesis

In this review the Hongso replacement set is evaluated as a practical parts kit for owners of the Weber Genesis 300 Series (2011-2016) with front control. The bottom line: this set is for someone who needs exact-fit replacement grill grates and flavorizer bars that restore searing performance and protect burners. The reviewer found the cast iron grates deliver consistent heat retention and the porcelain steel flavorizer bars shield the burner while promoting even cooking-making it a straightforward repair option rather than an upgrade.

Key Features

• Exact fit for Genesis 300 Series: Designed to match Weber Genesis E-310, E-320, E-330, EP-310, EP-320, EP-330, S-310 and S-330 models with front control, so installation is simple for those models.
• Cast iron grill grates: Heavy duty cast iron grates retain heat well to produce clear sear marks and help maintain steady cooking temperatures.
• Porcelain steel flavorizer bars: Five heat plates prevent food from direct flame exposure and help protect burners while promoting more even heat distribution.
• Correct dimensions provided: Grill grate dimensions (19.5 in x 12.75 in each; 19.5 in x 25.5 in total) and flavorizer bar size (17.5 in x 2.25 in x 2.375 in) are listed so buyers can confirm fit before ordering.
• Compatible with multiple Weber part numbers: Stated compatibility with many Weber model numbers gives confidence for owners of older Genesis 300 variants.

Who It's For

This kit is aimed at owners of the Weber Genesis 300 Series grills from 2011 to 2016 who need to replace worn grates and heat plates without modifying their grill. It suits backyard cooks who want the heat retention and sear of cast iron combined with the burner protection of porcelain steel flavorizer bars.

It is not intended for owners of the Genesis II series or users who expect a different material or a redesigned aftermarket upgrade; buyers should measure their existing grates and bars against the provided dimensions before purchasing to confirm compatibility.

Pros & Cons

Pros

• Durable cast iron grates deliver strong heat retention and reliable sear marks.
• Porcelain steel flavorizer bars protect burners and help distribute heat evenly across the cooking surface.

Cons
