Porcelain coated steel is the material that many domestic use cooking grills are made of. The other materials used for making cooking grills are porcelain covered cast iron, bare cast iron or stainless steel.
Porcelain coated gas grills are rust proof and easy to clean. However their major drawback is that they have a limited lifespan as they chip easily. Bare cast iron gas grills are vulnerable to rust. They need to be kept clean and oiled regularly to prevent rust.
These two types of gas grills – porcelain covered and bare cast iron grills- have been in use for a long time. They have been popular but have also contributed to the volume of work with their maintenance needs.
The use of stainless steel in gas grills has gone away with maintenance hassles due to chipping and rust. Stainless steel gas grills are rated as the best gas grills in use nowdays.
Basic gas grills that offer an area of 600-650 square inches, with a burning capacity of 10000-12000 BTU, are quite sufficient for many families.

This kind of a grill is designed to be large but inexpensive. Careful maintenance can see it through quite a few uses for several years.

Slightly more powerful gas grills that have a cooking capacity of 15,000 BTU can be purchased in a similar price range. One just needs to look for specifications mentioned by manufacturers to locate best gas grills as per personal preferences.
If one is not very keen on taking on additional maintenance responsibilities then stainless steel gas grills are the best gas grills to buy.
