9.5MM Grill Grates for Weber Spirit 300 Series - Durable 304 Stainless

In this review the 9.5MM Grill Grates are evaluated as a direct replacement for multiple Weber Spirit and Genesis models; they are best for home grill owners who want a durable, easy-to-clean upgrade that improves searing and prevents food loss. The reviewer found the 9.5MM triangular rods and 304 stainless construction deliver heavier, more stable performance than standard cast iron or thinner steel grates, while the sandblasted finish makes cleanup noticeably faster after a busy cookout.

Key Features

• Model compatibility: Fits a wide range of Spirit 300 and Spirit II 300 Series and many Genesis models, making it a flexible replacement for owners of E310/E320 series and compatible Genesis grills.
• 304 stainless steel: Heavy-duty 304 stainless resists warping and corrosion so the grates keep their shape and finish under repeated high-heat use.
• 9.5MM triangular rods: Thick triangular rods produce clear sear marks and more even contact with food for better browning.
• Precise spacing: 0.43' spacing prevents small items like shrimp or cherry tomatoes from slipping through while maintaining good heat flow.
• Sandblasted surface: Textured finish reduces sticking and shortens cleanup time - a quick scrub with soapy water removes most residue.
• Two-piece dimensions: Each grate is 17.4 in x 11.7 in, combined 17.4 in x 23.4 in, matching the original two-piece layout for easy installation.

Who It's For

These grates suit home cooks and weekend grillers who own compatible Spirit 300, Spirit II 300, or several Genesis models and want a long-lasting replacement that improves searing and reduces cleanup time. They are especially useful for people who barbecue steaks, vegetables, and small items that often slip through wider gaps.

Those who should look elsewhere include owners of incompatible Genesis Silver A models or grills with nonstandard cookbox dimensions; also customers who prefer the flavor absorption and maintenance routine of seasoned cast iron may not prefer stainless upgrades.
