Cast Iron Cooking Grates for Dyna-Glo DGH450CRP DGH474CRP - Reliable

In this review the reviewer looks at a set of three cast iron cooking grates designed as direct replacements for multiple Dyna-Glo and compatible grill models. The bottom line is simple: these grates are for grill owners who need a durable, heat-retaining replacement that fits from the original part number 70-01-911 and restores even heat and searing performance. Installation is straightforward and many users report the grill functions like new after swapping in these matte porcelain coated cast iron grids.

Key Features

• Exact fit: Designed to replace original part 70-01-911 so the grates sit properly in Dyna-Glo DGH450CRP and listed compatible models, avoiding alignment issues during installation.
• Durable construction: Matte porcelain coated cast iron offers solid build quality that resists rust and holds up to high temperatures for long-term use.
• Better heat retention: Cast iron material improves heat retention and promotes more even temperature distribution across the cooking surface for consistent results.
• Clear sear marks: The heavy cast iron surface leaves pronounced grill marks, which helps finish steaks, burgers, and vegetables with a grilled appearance.
• Easy to maintain: The grates clean up with soaking and a soft brush or sponge, and they respond well to routine seasoning to preserve the coating and reduce sticking.
• Value pack: The package includes three grates, covering multi-burner configurations so buyers replace all worn surfaces at once.

Who It's For

These cast iron grates are best for owners of Dyna-Glo 4- and 5-burner models and several compatible Backyard, Kenmore, and Uniflame grills who want a near-original replacement that improves heat retention and searing. Home cooks who prefer cast iron for its cooking properties and those replacing multiple worn sections will appreciate the three-pack.

They are less appropriate for buyers who need additional accessories such as igniters or who prefer lighter, nonstick coated grates that do not require seasoning. If low weight or a nonporous surface is essential, a different grate material should be considered.
