YOUFIRE Stainless Steel Cooking Grates for Weber Genesis 300 Series — 19.5" Two-Piece, 7mm Rods Rust-Resistant

YOUFIRE 19.5" stainless steel cooking grates are direct-fit replacement BBQ grids for Weber Genesis 300 Series models, delivering durable, corrosion-resistant performance and improved searing.

These replacement grates are precision-sized to match the original Weber Genesis 300 Series cooking surfaces and come as a two-piece set for full coverage. Built from thicker, food-grade SUS stainless steel with extra cross rods and parallel bars, the YOUFIRE grates aim to resist rust, retain heat evenly, and produce clean grill marks while preventing small items from falling through. They are designed as a stainless alternative to Weber 7528/7524 cast iron grates and are compatible with multiple legacy Genesis models.

Will these grates fit my Weber Genesis 300 Series grill?

Yes — these YOUFIRE grates are cut to the same dimensions as the original Weber 300 Series grates and replace the factory pieces directly on supported models. Confirm your grill model year and series to ensure compatibility, because they do not fit Genesis II 300 or Genesis II LX 300 series.

• Exact size: each grate 19.5 x 12.9 inches; two-piece combined 19.5 x 25.8 inches
• Compatible with E-310/E-320/E-330, EP-310/EP-320/EP-330, S-310/S-320/S-330 (specific years noted)
• Not compatible with Weber Genesis II 300 or Genesis II LX 300 series
• Also fits selected DCS, Uniflame, Kenmore, and Pit Boss models

How do these stainless grates perform compared with cast iron originals?

Stainless steel heats quickly, resists rust, and is easier to clean than cast iron, while still delivering bold sear marks and stable cooking. YOUFIRE uses thicker 7mm rods and additional bars for improved strength and more even heat distribution than many standard aftermarket replacements.

• Material: food-grade SUS stainless steel, non-magnetic and corrosion-resistant
• Thickness: 7mm rods (heavier and stiffer than typical 5mm grates)
• Weight: approximately 13.7 lb total for both grates, offering stability over thinner options
• Surface: smooth welded edges for safer handling and easy cleaning

Can I expect better cooking results or easier maintenance?

These grates are engineered to make grilling cleanup simpler and produce reliable sear lines while keeping small foods on the surface. The extra parallel bars reduce gaps and help prevent food from falling through, and the stainless finish needs less seasoning and rust care than cast iron.

• 18 parallel bars per grate for tighter food support and consistent sear marks
• Smooth welds prevent food from catching and simplify wiping or washing
• Stainless surface cleans with brush, soap, and water—no regular re-seasoning required
• Even heat transfer thanks to heavier construction for more predictable cooking

How durable are these grates for regular outdoor use?

Constructed from thicker, food-grade stainless steel and welded for strength, YOUFIRE grates stand up to frequent grilling and outdoor conditions better than many lightweight replacements. They are built to be corrosion-resistant and less prone to warping under typical barbecue temperatures.

• 7mm thick rods for improved rigidity and longevity
• Non-magnetic SUS stainless steel resists rust and discoloration
• Welded construction avoids loose rods and reduces fatigue over time
• Heavier overall mass helps maintain contact with heat source

Who is this for: The YOUFIRE Genesis stainless steel replacement grates suit owners of older Weber Genesis 300 Series grills who want a low-maintenance, rust-resistant alternative to cast iron or thinner aftermarket grids. Choose these grates if you need a precise drop-in fit for legacy Genesis models, want clearer sear marks and easier cleaning, and prefer a heavier, more durable stainless solution for frequent backyard grilling.
