GRISUN Stainless Steel Grill Grates for Weber Spirit 300 Series — 2-Pack 304 Stainless, 7mm Rods, Direct-Fit

These GRISUN 7639 replacement grill grates are heavy-duty 304 stainless-steel cooking grates designed to drop into compatible Weber Spirit, Genesis, and Smokefire models and restore even heat, durable searing, and long-term rust resistance.

If your original Weber cooking grates are warped, rusted, or missing, the GRISUN 7639 set offers a direct-fit stainless-steel replacement engineered for the Spirit 300 series and many other Weber models. Each rod measures 7 mm in diameter and the pair covers the same footprint as the OEM parts, so you get reliable heat distribution, clean grill marks, and a maintenance-friendly surface that resists corrosion compared with cast iron or plated steel.

Which Weber and compatible grills will these grates fit?

The GRISUN 7639 grates are built to match the dimensions and mounting points of several Weber Spirit, Genesis and selected Smokefire models. They are cross-listed as replacements for multiple Weber part numbers, so they slide into place without modification on supported grills.

• Compatible with Weber Spirit E-310/E-320/E-330 and S-310/S-320/S-330 series
• Fits older and newer Genesis models including Genesis I–IV and Genesis Silver/Gold/Platinum B/C
• Also listed as replacement for Weber part numbers 7638, 7525, 7527 and others
• Works with select Weber Smokefire EX4/EX6 pellet grills

How does 304 stainless-steel improve grilling performance?

304 stainless steel is non-magnetic, corrosion-resistant, and holds up well to repeated heating cycles. The solid 7 mm rods transfer heat efficiently for consistent searing and grill marks while resisting cracking or flaking that can shorten the life of thinner grates.

• 7 mm rod diameter for stronger, longer-lasting bars
• Even heat distribution to reduce cold spots and hot streaks
• Corrosion resistance lowers maintenance compared with bare cast iron
• Sleek surface makes cleaning easier and food release better

What are the dimensions and what comes in the package?

Each cooking grate in the pair measures 17.3 x 11.8 inches, matching the footprint used in many Spirit and Genesis cooking chambers. The set ships with two identical stainless-steel grates so you replace both halves of the primary cooking surface at once.

• Two stainless-steel cooking grates per package
• Individual grate size: 17.3 x 11.8 inches
• Solid rod construction for rigidity and longevity
• Ready to install—no trimming or adapters required on listed grills

How should I maintain these stainless-steel grates for best life?

Keep grates in top condition by preheating, scraping after use, and periodic deep cleaning. Using high-heat burn-off and a stainless-steel brush preserves the finish and prevents buildup that can affect flavor and heat transfer.

• Preheat grates to loosen residue before brushing
• Use a stainless-steel grill brush or nylon pad while warm
• For heavy buildup, soak in warm soapy water or use a dedicated cleaner
• Store in a dry place when not in use to minimize exposure to elements

Who is this for: The GRISUN 7639 304 Stainless Steel Grill Grates suit gas grill owners who want a durable, OEM-fit replacement for worn or corroded cooking grates. Ideal for backyard cooks using Weber Spirit 300 series, select Genesis models, or Smokefire pellet grills who value better heat distribution, easier cleaning, and corrosion resistance without changing the cooking dimensions of the grill.
