Hongso Stainless Steel Grill Grates for Weber Genesis 300 — 304 SS, 7mm Solid Rods, Direct-Fit Replacement

If your Weber Genesis 300-series grill needs new cooking grates, the Hongso 7528 set offers a durable 304 stainless steel upgrade designed for long life and consistent searing. Each grate measures 19 1/2" x 12 3/4" (19 1/2" x 25 1/2" total) and is built from solid 7 mm rods with rounded ends for safer handling. These grates passed SGS testing and are intended as direct-fit replacements for specified Genesis models as well as a variety of other grill brands and part numbers listed below. Note the important compatibility exception: they do not fit Genesis II (2017 and newer) or Spirit series grills.

How durable are these Hongso stainless steel grates?

Manufactured from 304 stainless steel, the grates resist corrosion and withstand frequent high-heat cooking. The rods are solid and thicker than many stock porcelain-coated grates, giving them a longer usable life and lower risk of chipping or flaking.

• Material: 304 stainless steel for rust resistance.
• Rod diameter: 7 mm solid rods for strength and heat retention.
• Weight and build: substantial feel (around 10 pounds total) for stability.
• Safety: rounded rod ends to prevent cuts and snagging.

Will these grates fit my grill model?

They are designed to fit Weber Genesis E, S and EP 300 series grills produced from 2007 through 2016, including model numbers E-310, E-320, E-330, S-310, S-320, S-330, and EP-310/320/330. They also list cross-compatibility with numerous other models and brands—check your original grate dimensions to confirm a match before ordering.

• Exact dimensions: each grate 19 1/2" x 12 3/4" (total 19 1/2" x 25 1/2").
• Weber part references: compatible with parts 7528 and 7524, and several 651xxxx series grills.
• Works with select DCS, Uniflame, Kenmore, Brinkmann, Charmglow, Nexgrill, Turbo and KitchenAid models—refer to vendor list.
• Important exclusion: NOT compatible with Genesis II (2017+), Spirit series, or unspecified models—measure first.

How do these grates affect cooking performance and maintenance?

Solid stainless rods provide good heat transfer and even searing across the surface. Food release is improved compared to worn porcelain grills, and cleaning is simpler: stainless tolerates scrubbing and high-heat burnoff without the risk of coating flaking.

• Better sear due to thicker, solid rods that hold heat evenly.
• Reduced food sticking when properly preheated and oiled.
• Easy cleaning: withstands wire brushing and high-temperature cleaning cycles.
• Longer life than porcelain-coated grates that can chip or peel.

Who is this for: the Hongso 7528 grates are ideal for owners of Weber Genesis E/S/EP 300-series grills (model years 2007–2016) seeking a robust, long-lasting stainless-steel replacement. They also suit owners of compatible DCS, Uniflame, Kenmore, Brinkmann, Charmglow, Nexgrill, Turbo, and KitchenAid models listed in the parts compatibility notes who want improved heat retention, easier maintenance, and a safer grate edge. If your grill is a Genesis II (2017 or newer) or Spirit-series, measure your existing grates before buying—these will not fit those models.
