We offer four main grate styles: Expanded Diamond Grates (Steel and Stainless), Stainless Free Float Round Rod Grates, and Argentine V Grates (Steel and Stainless), and Griddles (Steel and Stainless).
Steel grates are bare steel, and are cared for like a cast iron skillet. They must be seasoned with oil or animal fat for rust protection. The grease should not be cleaned completely off them each use. Alternatively, stainless grates are naturally rust resistant. If the grates are new or haven't been used in a while, oil may be needed to prevent sticking. 
Expanded Diamond Grates are a wonderful, multipurpose grate that you can use to cook pretty much anything. They are flat which makes them perfect for flipping burgers and steaks. They have small openings which also make them ideal t for cooking veggies, shrimp, and smaller items directly on the grate. They are easy to clean with a grill brush. Metal expands when it's heated, so the grate may bow slightly in the center when you're cooking. This is normal. We do not weld the expanded into the grate frame which allows you to flip the grate as needed. Expanded grates come in bare steel and stainless options. 
Stainelss Free Float Round Rod Grates are our longest lasting grate selection. They are built with a hollow tube framework in which holes are drilled to house each individual solid rod. If you ran your hand over the grate each rod would spin, making them very easy to clean. The rods are "free floating", allowing for the natural expansion and contraction of the grate as the temperatures change. Free float rod grates adapt to each temperature change, making them very warp resistant. Available in stainless (rust resistant) material.
Argentine V Grates are ideal for cooking fatty cuts of meat. If crispy, skin-on chicken is your priority then Argentine grates can't be beat. The V grooves run front to back and are slightly tilted forwards in their frame which allows the fats to be caught and rolled forward into a removable front drip pan. The drip pan slides off the front of the grate frame. The fats can be used to baste or can be discarded after use. They are available in stainless (rust resistant) material.
Griddles ("planchas") are a flat surface without perforations. They can be used to cook eggs, pancakes, chorizo, burgers, etc. Really anything you cook in a pan can be cooked on a griddle. They feature an integrated drip pan in front where drippings can pool. They are available in bare steel (steel grates must be seasoned like cast iron) and stainless (rust resistant) material.

We offer two grill grate material options, steel and stainless. Here's some specifics about each material to help you make a decision about the grate that's best for you. I've found that most people make the 'material decision' based on cost, ease of care, and longevity.

You may also mix materials by selecting steel for the unit, but add a stainless grill grate upgrade. However if you select a stainless unit, the grill grate should always be stainless as well. 

Steel grills are the more affordable option, while stainless grills are a slightly more expensive investment. 

Steel is an alloy (combination of elements) composed of Iron and Carbon. The raw material is relatively inexpensive in comparison with stainless. It's easily formed and a faster welding process. Steel grill grates cannot be coated with paint, so they must be 'seasoned' with oil to prevent oxidation. Care is very similar to cast iron. When you clean your grill after use it's important to re-season the grate as it's left outside until your next cook. Many enthusiasts love cooking on a seasoned grate and don't mind the little bit of extra care. For the budget conscious it's a great option.  

Stainless is an alloy (combination) of Chromium, Nickel, and Carbon. We use only '304 Grade' stainless. Stainless is an expensive material in comparison with steel. It takes more time and is harder to fabricate. It's more difficult to form into shape, harder to drill and cut, and a longer welding and finishing process. All of these things make a stainless grill a more expensive investment. 

The most beneficial quality of stainless for our purpose is it's natural property of corrosion/rust resistance. Under normal conditions the chromium in stainless will react with oxygen in the air and create a thin and very protective passive layer on the material. This reaction is the reason that stainless steel is such a rock star against corrosion and rust.

Overall stainless grills are our longest lasting option and require the least amount of care by you. Do the benefits outweigh the extra cost? Hopefully you have the information to make a decision that is right for you.

Exposure to certain conditions such as excessive moisture or sea/salt air will expedite the oxidation process. Stainless is the best option if that describes your living situation.
