Although wooden shelves give out a classic and traditional look that is hard to beat, these shelves are harder to maintain compared to stainless steel ones. Wooden shelves always look sophisticated especially when they're filled with different kinds of books. They make a room seem a lot classier, but aren't necessarily built to be durable and long lasting.
Strong wooden shelves are usually made of hard wood, which could get really expensive. So, those looking for something that is low maintenance and long lasting turn to stainless steel instead.
Stainless steel shelves have a lot of different advantages. First off, these are highly durable. Although hard strikes on the surface could dent them, breaking them would be harder than breaking wood. Wood could also chip and crack through time, but stainless steel wouldn't.
Another disadvantage with wooden shelves is keeping its au naturel look. Wood often looks best when it’s showing its true colors, but time could wear this out and make it look dull. Although painting on it is easy, it's not going to be the same. Stainless steel, on the other hand, can come in different colors, and when faded or chipped off, can be easily given a new coat of paint.
Assembly is also an issue as most wooden shelves need to be put together before it arrives at your home or office. Stainless steel, however, can be taken apart and reassembled once it gets into the room where you'll be putting it in.
