Uniflasy Cast Iron Grill Grates for Weber Q300/Q320/Q3000/Q3200 — 2-Piece Replacement, Heavy-Duty Heat Retention

Uniflasy 7646/7584 cast iron replacement grates provide two heavy-duty cooking surfaces sized to fit Weber Q300/Q320 and Q3000/Q3200 grills, restoring even heat and searing performance.

These two cast iron grates (25 x 17.8 x 0.5 inches total) are made as drop-in replacements for many Weber Q series gas grills, offering stronger heat retention and a rugged cooking surface compared with thin factory bars. They suit owners who want to refresh worn, cracked or rusted grates without replacing the entire grill. Seasoning the grates before use and routine dry storage prolongs life and maintains nonstick performance.

Will these grates fit my Weber Q model?

The Uniflasy 7646/7584 pair is designed to match the cooking area of Weber models such as Q300, Q320, Q3000, Q3100 and Q3200 (including part numbers like 586002, 57060001 and 404341). Measure your current grate or compare model numbers to confirm compatibility before purchasing.

• Two-piece design covers the standard Q-series cooking surface in halves.
• Overall dimensions: 25 x 17.8 x 0.5 inches (each half fits one side).
• Check grill model or existing grate measurements for exact fit.

How do cast iron grates change cooking results?

Cast iron holds and distributes heat more evenly than thin steel bars, producing better sear marks and steady temperatures for meat, fish and vegetables. Because cast iron absorbs heat, it helps maintain consistent cooking when the lid is opened and closed.

• Improved searing and caramelization for steaks and burgers.
• More stable surface temperature across the grill area.
• Holds heat longer—useful for quick high-heat sears.

What maintenance does cast iron require?

Cast iron needs regular care to prevent rust and keep a natural nonstick finish. After each use scrape away food debris, dry the grates thoroughly, and apply a light coat of cooking oil; store in a dry place or under the grill cover when not in use.

• Scrape or brush after each cook while still warm.
• Hand-wash, dry completely, then oil lightly to protect the surface.
• Season the grates before first use for best results.

Can these grates replace damaged originals without extra tools?

Yes—Uniflasy grates are sold as a two-piece set meant for straightforward placement into compatible Weber Q grills. No special tools are required for installation; simply lift out the old grates and set the new pieces into the grate supports.

• Two halves make handling and placement easier and safer.
• Direct drop-in replacements for specified Weber Q series models.
• Ideal for replacing rusted, bent or cracked factory grates.
