DIYers and grill enthusiasts understand what it takes to achieve a perfectly seared steak that is grilled to perfection. Whether it’s understanding basic BBQing principles or acquiring the right equipment to take your grilling to the next level, premium grill grates manufactured from high-quality materials like stainless steel and cast iron help achieve the desired results.
For a metal to be used for a grill grate, it must display certain features that allow the proper transfer of heat from the grill to the meat. Without the correct heat transmission, the meat will either burn, not cook properly, or cook unevenly. To prevent these mistakes, your grill grate should provide the following features:
The basic material choices for grill grates include:
Of these options, cast iron and stainless steel are the most durable materials with the highest heat capacity.
When comparing grill grate materials, two clear-cut winners stand out from the rest: stainless steel and cast iron. If you are asking yourself what type of grill grate lasts the longest? Or which grill grates are easiest to clean? Both stainless steel and cast iron provide proven results. But which material of the two is the clear-cut favorite? Some of the most viable comparisons of the two materials are communicated below.
Most low-cost grill grates are made of plain or plated steel.
These won’t last long in the heat and will eventually warp, rust,
and begin to stick. Stainless steel is a much sturdier material that
resists corrosion and prevents food from sticking.
Stainless may not be as glamorous as cast iron grill grates. But the
benefits of stainless are many, especially for an outdoor appliance,
because it can better withstand the elements. The metal heats up
quickly, though it won’t hold as much heat as cast iron, so cooking
slows down once the heat source is removed. Stainless steel grates
are long-lasting, require very little maintenance, won’t rust or
corrode, and are much easier to clean than cast iron. If they darken
over time, the stain can be removed with a grill brush.
Everyone is familiar with Grandma’s well-seasoned cast iron pan,
and cast iron grill grates offer the same gourmet performance. Many
grilling purists would have nothing else. For one thing, cast iron
holds a lot of heat, producing a mouth-watering pattern of sear marks.
The oily seasoning helps prevent food from sticking and, when cared
for properly, can last a lifetime.
One drawback of cast iron
grates is the maintenance required. Like Grandma’s pan, plain cast
iron must be seasoned before use and regularly cleaned and oiled.
Keeping up with the maintenance will help prevent the cast iron from
rusting. You may want to bring it inside when it’s not going to be
used for a while.
But if you don’t want the bother, choose cast
iron coated with porcelain enamel. Just be aware that over time the
coating may develop cracks, which allow water to reach the metal
beneath, eventually leading to rust. Plus, the coating prevents those
excellent grill marks and dampens the sizzle when the meat hits the grill.
Which metal will you choose for your grill grate? It’s a tradeoff. Most casual grillers may opt for stainless steel for the less complex upkeep. However, cast iron provides a more thorough cook, providing a higher quality final product. But either way, be sure to keep it well-maintained, and it will give you years of service.
