Stainless steel is a phrase that is a little bit confusing or should I say it is a confusing phrase. Nothing special makes stainless steel any special; it isn’t the steel or stainless. Stainless steel can discolour, can rust and can lose the lustre appearance after over some time. There are different types of stainless steel, and this also applies to steel gas grills. Therefore, you now have a hint to consider while shopping for a stainless steel barbecue. Look at the grade, thickness, among other factors.

Factors to consider when buying stainless steel BBQ


There are two major grades of stainless steel; 304 and 430. The common grade of stainless steel is 304, which amounts to about 50 per cent of the total stainless steel in the world. This grade of stainless steel is used diversely from cars, kitchenware, buildings, etc. Grade 304 steel is non-magnetic with superior corrosion resistance. Some parts of the barbecue grill parts are made from grade 304, and other parts are made from 430, which is not as resistant as 304. When you want to check the grade of stainless steel start with putting the magnet on, and if the magnet sticks on to it, it is 430, and if it does not, it is 304. The quality of a BBQ is determined by the amount of 430 or 304 available in the gas grills. The one with most of 430 is of high quality than the one with more of 304. Some manufacturers mix the gas grill plates made from 430 and those from 304 so, make sure you test all the grill plates with the magnet to avoid disappointment later.


You probably do not need a pair of calibre to determine the thickness of stainless steel. By only looking at them, you can tell the one with thicker gas grills. The thicker metals are better than thinner ones, and they will not discolour quickly as the thinner ones do. It is possible to tell the thickness of the gas grill by their weight and the hardiness of the metal. You can press the middle of the metal grills, and if they are sturdy and not bent easily, then they are thick.

Stainless finish

The entry point of the rust is on the weak spots of your metal grills. If there are imperfections on the surfaces of your steel and that is where rust is going to start their mission from. Although stainless steel may be resistant to corrosion, it doesn’t mean they are immune, at one point in time they will bow to these problems. When you are testing the finish of the grills, make sure they have a clean finish and sheen. Better stainless steel finish should feel smooth when touched by hand while a poor one feels uneven.

Parts assembly

Stainless steel should be assembled properly to make the most out of the metal’s resistance to corrosion. Spot welding shouldn’t leave vulnerable parts of the joints which may lead to corrosion. It is better to use a continuous welding rather than spot welding. The best gas grills have continuous welding, so, that is what you should be looking for when it comes to parts assembly. This is an expensive process that is why you cannot find them on the lower end grills. Another option is to assemble them using nuts and bolts instead of welding.
