How are these grates built and what materials are used?

Each grate is constructed from heavy-duty solid stainless steel rods for enhanced strength and corrosion resistance. The rods are thicker than many aftermarket options, which improves load capacity and helps maintain even heat across the entire cooking area.

• Material: solid stainless steel for rust and heat resistance.
• Rod diameter: 8mm solid bars to prevent bending or sagging.
• Dimensions: each grate 18-15/16" x 11-1/4"; total covered width 33-3/4" with three pieces.

Do these grates affect cooking performance and cleanup?

The 8mm solid rods promote uniform heat distribution and strong searing while being dense enough to reduce food falling through. A smooth stainless finish limits stubborn grease buildup so routine cleaning is faster and simpler than porous or flaking coatings.

• Thick rods keep steady heat for consistent searing and grill marks.
• Smooth stainless surface resists food adhesion and cleans easily.
• Split-panel design enables quick tool-free removal for cleaning or replacement.

How easy is installation and are replacement parts included?

Installation is straightforward: the three split panels slide into place without special tools, mirroring the original factory layout. The package supplies a full set of three cooking grates sized to cover the entire cooking area of compatible Genesis models.

• Package includes a 3-pack of cooking grates for full coverage.
• Tool-free, split-panel design for fast removal and replacement.
• Designed to match the mounting points and spacing of OEM grates.
