The best one is 304 steel as it is rust free, 202 is cheaper because it may have rust after few years/months. Do not use 202 for exterior work like balcony or gate, it can be used in internal stairs railing are which is not exposed to nature. 16 gauge is the best thickness, 18 has lesser thickness, 20 is more thinner and 22 is the thinnest. So use 16 gauge if possible.

The most widely used steel is the 304 , also known as 18/8 . The second most common steel is the 316
grade, also called marine grade stainless, used primarily for its
increased resistance to corrosion..
