Is There a Grill that Does Not Rust?

There is no grill that will not rust. Take note that even high-quality and rust-resistant grills will eventually rust and corrode over time. Rusting begins when the iron is exposed to oxygen. If this happens, it forms a ferric oxide layer. Because the molecules of ferric oxide have a larger volume as compared to steel molecules, it eventually causes stress between the two molecules and the rust layer begins to separate from the steel. As a result, more of the steel is being exposed to the atmosphere which encourages the rust cycle to continue and end up damaging the steel.

Do All Grills Rust?

All grills will eventually rust. Take note that rust is common on metallic objects, especially those that are left outdoors. While it is true that some high-quality grills are immune to rust, it is only to some extend and that they require proper care and maintenance or they might get rusty as well.

Will a Stainless Steel Grill Rust?

Stainless steel is vulnerable to rust. To create stainless steel, chromium is added to the iron. Iron is the dominant metal mixture that increases its resilience to rust. On the other hand, rust is a type of corrosion that affects both iron and steel. When iron reacts with oxygen which is a process called oxidation, rust can form. Moreover, aluminum and other metals are also prone to corrosion because of oxidation. The good news is that all types of corrosion can be easily prevented by doing proper care and maintenance. The signs of corrosion include discoloration, blemishes, and tiny pits that detract from the grill. These are visible to the naked eye and should be remedied as soon as possible to prevent further damage to happen on your grill.

Materials Used for Making BBQ Grills

In the olden days, cavemen dug a hole in the ground to burn wood. This leads to the soil being the first material used for grilling. Nowadays, grills are typically made of metals which include sheet metal, cast iron, and stainless steel. Let us learn more about these materials below.

Cast Iron

These types of grills can be traced back to ancient times. It is commonly called hibachi grills in Asia. The traditional hibachis are designed to be small and rectangular. Cast iron hibachi grills have become popular in the US during the 21st century. They are commonly used by those who are living in apartments that have limited outdoor space.

Gas grills grates are usually made from stainless steel, cast iron, porcelain, or just plain steel. These materials are commonly chosen because the intense heat that comes from the grill can easily wear down metals that are thinly or poorly made. Let us learn more about each material and its quality below.

Porcelain Grates

A porcelain-coated steel grate is a popular choice. On the other hand, the coating can chip away which exposes the metal underneath to moisture. As a result, rust can settle on the surface over time. Take note that porcelain-coated grates are a good choice as long as you choose one that is of high quality. Do not get tempted by the price because cheap porcelain coatings can easily get damaged and will not be worth the money that you have paid. Moreover, do not use hard tools and metal scrapers on porcelain-coated grill grates as they can damage and chip the coating from the grate.

Steel Grates

This is considered to be the most affordable material on the list. On the other hand, plain steel can lose its temper with constant use. As a result, it starts to chip. When this happens, the surface of the grill becomes rough and uneven which makes the food stick. Moreover, stainless steel can lose its non-stick abilities when they get chipped up. Make sure to keep stainless steel grates clean and well maintained so that they last for a long time.

Cast Iron Grates
