Hongso 18 7/8 in SUS304 Stainless Steel Grill Grates Set - Replacement

In this review the Hongso 18 7/8 in SUS304 stainless steel grill grates are evaluated as a direct replacement for Weber Genesis II 400 series models. These grates are aimed at owners who need a durable, food-grade replacement that restores searing performance and even heat retention. The single biggest reason to buy is the solid 7mm SUS304 rods that promise improved heat retention and easy cleaning compared with cast iron; the reviewer found them a practical, affordable option for restoring cooking performance on compatible Genesis II grills.

Key Features

• Compatibility: Fits Weber Genesis II and LX 400 series (2017 and newer) models, making it simple to replace worn OEM grates without modification.
• Material: Made from solid 7mm SUS304 food-grade stainless steel rods for corrosion resistance and long-term use in the outdoor environment.
• Cooking performance: Thick stainless rods retain heat evenly and deliver clear sear marks for professional-style grilling results.
• Dimensions and set: Each grate measures 18 7/8 in x 11 1/4 in including tabs, with a total footprint of 18 7/8 in x 33 3/4 in for the set of three, matching common Genesis 400 layouts.
• Safety and finish: Smooth, non-sharp edges and SGS-tested non-toxic construction reduce handling risk and meet basic safety expectations.
• Maintenance: Stainless construction is easier to clean than cast iron and generally resists rust when cared for properly.

Who It's For

This set is best for owners of Weber Genesis II E410, S410, E415, S415, E435, S435 and corresponding LX E440/S440 models who want a like-for-like replacement using food-grade stainless steel. It suits grillers who value easier cleaning and strong searing ability without the weight and maintenance of cast iron.

Those who should look elsewhere include owners of older Genesis 300 series or pre-2016 models, since these grates are not compatible, and buyers seeking coated or porcelain options for specific aesthetic finishes rather than exposed stainless rods.
