Hongso 17.5ft SUS304 Stainless Steel Grill Grates - Durable

In this review the Hongso 17.5' SUS304 stainless steel grill grates are examined as a direct replacement for multiple Weber Spirit and Genesis gas grills; the bottom line is simple: if you want heavier, rust-resistant cooking grates that match original fitment for older Weber models, these deliver. The review focuses on fit, build quality and everyday performance; the heavy 7mm SUS304 rods and the fact they are sold as a set of two make them an attractive upgrade for owners of Spirit 300 series, Spirit II/GS4 300 series and many Genesis models seeking long-term value and easier cleaning.

Key Features

• Material: Constructed from 7mm thick SUS304 food-grade stainless steel rods for improved rust resistance and durability compared with thinner or porcelain-coated grates.
• Fitment: Designed to fit Weber Spirit 300 series and Spirit II/GS4 300 series grills as well as a wide range of Genesis models, making replacements straightforward for many older grills.
• Rod layout: Each section contains 16 rods at 1/4 spacing for even heat contact and grill marks while reducing food sticking compared with wider porcelain rods.
• Dimensions and set: Each cooking grate measures 17.5' x 11.9' and is sold as a set of two, matching the footprint of listed Weber replacement parts for easy swap-in installation.
• Cleaning and maintenance: Stainless construction simplifies cleaning after use and resists chipping or flaking that affects coated grates over time.

Who It's For

These grates are well suited for owners of Weber Spirit E310/E320/E330 and Spirit S310/S320/S330 models, Spirit II/GS4 300 series grills, Spirit SP320 and many Genesis Silver and Gold B/C variants who need a heavy-duty replacement that will outlast the original porcelain grate. They are ideal for grillers who value durable stainless steel quality and easier maintenance.

They are less appropriate for someone who specifically needs the original porcelain finish for aesthetic matching or for models explicitly not compatible, such as Genesis Silver A. Buyers who require custom or non-standard dimensions should confirm measurements before ordering.

Pros & Cons

Pros

• Excellent build quality and heavier rods mean the grates feel more durable than many OEM porcelain options.
• Good fit across a wide list of Spirit and Genesis models, simplifying replacement for older grills.
• Stainless surface is easier to clean and resists rust better than coated alternatives.

Cons

• Not compatible with every Weber generation, so model verification is required before purchase.
• Heavier stainless steel will transfer heat differently than porcelain, which may slightly change cooking characteristics for users expecting identical performance.
