Gas grill burners come in many shapes, sizes and materials depending on your specific grill. What can be said more generally is that whatever metal your burner is made of will tell you pretty much how long it will last.
Burners range from aluminized steel at the low-end to cast brass and stainless steel on your high end grills. Low end burners will typically last about 3 years under normal circumstances.
Because the burner is inside the grill, it easily becomes coated in burnt grease and can corrode quickly. To help your burners last longer, regularly inspect and clean your burner. If your burner is damaged or too heavily corroded you will need to replace it.
