Uniflasy 19.5 in Grill Grate for Weber Genesis 300 Series - Durable

In this review the Uniflasy 19.5 in grill grate is evaluated as a direct replacement for select Weber Genesis 300 series grills; it is aimed at owners who need a stronger, easier-to-clean set of grates without paying for factory parts. The single biggest reason to buy is the heavier 7mm solid rod construction combined with 304 stainless steel, which gives the grates a reassuring feel and simplified maintenance compared with thinner aftermarket options. The review focuses on fit, build quality, and everyday use on Genesis E/S/EP and S models from the specified years.

Key Features

• Compatibility: Designed for Weber Genesis 300 series models including Genesis E/EP 310 and 320 (2007-2016) and Genesis S 310 and 320, offering a close fit for supported cookers.
• Durable construction: The 7mm solid rod design and 18 parallel bars provide greater resistance to deformation than thinner grates, so they stay flatter under heavy use.
• 304 stainless steel: Material choice resists rust and corrosion better than many coated grates and makes surface cleanup straightforward after grilling.
• Complete pair: Each order includes two grates sized 19.5 x 12.9 in each, matching the split grate layout and covering the full 19.5 x 25.8 in cooking area for Genesis 300 series models.
• Weight and feel: At roughly 13.7 lb total, these grates feel solid and substantial compared with some originals, which can translate to more stable cooking and searing.

Who It's For

This set is best for owners of the compatible Weber Genesis 300 series grills who want a robust, uncoated stainless replacement that is easy to clean and holds its shape. Home chefs who value stronger rods for even contact and searing will appreciate the heavier 7mm bars and the increased bar count for more consistent grill marks.

Those who should look elsewhere include owners of Genesis II 300 or Genesis II LX 300 series grills (these do not fit), and buyers who expect a lifetime rust-proof guarantee; while the 304 stainless is resistant, some users reported rust over time, so heavy coastal exposure or lack of maintenance may warrant a different solution.

Pros & Cons

Pros

• Thicker 7mm rods and 18 bars provide strength and improved searing surface.
• 304 stainless steel construction simplifies cleaning and reduces immediate corrosion risk.
• Included pair covers the full split-grate footprint and matches common Genesis part dimensions for a snug fit.

Cons

• Not compatible with Genesis II 300 or Genesis II LX 300 series, so careful model checking is required before purchase.
• Some customers report rusting within a year in real use, so long-term corrosion resistance may vary with maintenance and environment.
