SHINESTAR Stainless Steel Cooking Grates for Weber Genesis 300 Series - 19.5 x 12.9 in, 304 SS Heavy-Duty 18-Bar Set

If your Weber Genesis E-310, E-320 or E-330 (E/S/EP-310, 320, 330) needs new grates that hold heat, avoid warping, and stop small food from falling through, these SHINESTAR grates offer an engineered upgrade. They replace Weber part #7528 and are built from solid 304 stainless steel with a dense 18-bar layout to increase durability, heat retention, and food support compared with thinner or porcelain-coated options.

Will these grates fit my Weber Genesis 300 series grill?

Yes, the grates are specifically sized for the original Genesis 300 series models manufactured between 2007 and 2016, including E/S/EP-310, E/S/EP-320 and E/S/EP-330. They match the footprint and mounting points of Weber part 7528 for a straightforward swap.

• Each grate measures 19.5" x 12.9"; set covers 19.5" x 25.8" total
• Designed for 2007–2016 Genesis 300 series only
• Not compatible with Genesis II, Genesis II LX 300 series, or Spirit series

What makes the SHINESTAR stainless steel different from stock grates?

SHINESTAR uses 100% 304 stainless steel rod construction, thicker rods, and a denser bar pattern to resist corrosion, minimize warping, and deliver better searing. The non-magnetic 304 alloy is SGS-tested for quality and offers a longer service life than standard porcelain-coated cast iron or thin stainless replacements.

• Solid 7mm-thick rods and robust crossbars for strength
• 18 parallel bars per grate for tighter spacing and better food support
• Smooth, rounded rod edges to protect hands during handling

How do these grates affect cooking performance?

Thicker 304 stainless rods and a dense bar layout enhance heat retention and promote more even heat distribution across the cooking surface. You’ll get clearer sear marks and fewer hot spots, while the tighter spacing reduces food loss into the firebox and lowers sticking.

• Improved heat flow reduces temperature variance across the grate
• Dense 18-bar pattern prevents small foods from falling through
• Rounded bars help food release, making cleanup easier

How durable and safe are these grates for long-term use?

Constructed from heavy-duty 304 stainless steel and weighing about 13.5 pounds per set, these grates are built to withstand repeated high-heat cycles without cracking or flaking. The alloy’s corrosion resistance and the solid rod design mean less long-term maintenance and reliable safety for food contact.

• Non-magnetic 304 stainless resists rust and high-heat damage
• Thick rods and solid crossbars reduce the risk of bending or warping
• SGS-tested material quality for dependable performance

Who is this for? These SHINESTAR replacement grates suit Genesis 300 series owners (2007–2016) who want a long-lasting upgrade from porcelain or thin cast-iron grates. If you need exact-fit replacements that improve searing, reduce food loss, and require less frequent replacement, this heavy-duty 304 stainless set is a practical investment for serious home grillers and weekend chefs who expect consistent results and fewer maintenance hassles.
