Stanbroil stainless-steel cooking grates replace worn Summit 400 grates with a durable, solid-rod design that resists corrosion and improves searing.

If your Weber Summit 400-series grate is warped, rusted or simply past its prime, these Stanbroil replacement cooking grates are sized to match and built to last. Each pack contains two solid-rod stainless-steel grates sized 19.2" x 11.8" (total coverage 19.2" x 23.6") with 7mm diameter rods that create attractive sear marks and hold heat evenly. They’re an aftermarket option—designed to fit a long list of Summit models—offering a non-stick surface once seasoned, smooth rounded rod ends for safer handling, and a straightforward cleaning routine to extend service life.

How do these grates perform for searing and cleanup?

The solid stainless rods retain heat and deliver pronounced sear lines that elevate presentation and flavor development. They’re not porcelain-coated, so they’re less prone to chipping; routine seasoning and scraping after use keeps them performing like new.

• Solid rods (0.28" / 7mm) preserve heat for better searing.
• Round rod ends prevent sharp edges and make handling safer.
• Clean with a brush and warm soapy water; dry and oil to prevent surface corrosion.

Are these grates non-stick and easy to maintain?

When properly seasoned with a high smoke-point oil, the stainless-steel surface becomes effectively non-stick for most foods. Regular scraping, oiling after each cook, and storing the grates dry will extend their service life and keep them performing smoothly.

• Season before first use with peanut, grape-seed, or other high-temperature oil.
• Scrape grates after every cook and brush with oil to maintain non-stick qualities.
• Keep grill dampers open slightly to avoid condensation; cover when not in use.

What longevity and safety differences should I expect versus other grate types?

Compared with hollow-tube or porcelain-coated grates, solid-rod stainless steel offers increased durability and fewer failure points. The smooth, rounded rod ends reduce the risk of cuts during handling and make these grates friendlier for frequent deck-side maintenance.

• Solid rods resist cracking and chipping better than porcelain-covered grates.
• Stainless steel resists heat-induced deformation under regular cooking temperatures.
• Rounded ends eliminate sharp edges found on some aftermarket parts.

Who is this for? These Stanbroil grates are ideal for Summit 400 owners who want a robust aftermarket replacement that improves searing and lasts longer than porcelain alternatives. Choose them if you need exact-fit grates for a Summit-series gas grill, prefer stainless-steel durability, and are willing to follow simple seasoning and maintenance steps to maximize non-stick performance and lifespan.
