In many of those locations, you can also find valuable items, for example, large amounts of credits, palmtops with access codes or grenades. For discovering secret areas, you can receive 100-300 experience points.
The game rewards the player for checking every corner of the map. Some iron bars can be destroyed, but you must use something stronger for that (for example a grenade). The rare exception are secret entrances (for example behind a wall) and large iron gates - objects on which you don't see the durability bar. Probably the most important piece of advice for beginners in exploring inaccessible locations is that you can use brute force if you don't feel like looking for secret entrances, using (not always properly developed) hacker skills or expensive Multi-tools! If being sneaky doesn't matter to you, then choose a weapon and destroy any door, ventilation grills or hatches obstructing your way. Avoid the enemies completely, or incapacitate them, and use stun weapons. For example, if you want to sneak your way through the whole game and avoid killing other people, try to act in such a way from the beginning. Before you begin the game, think about your style of gameplay. It will offer a harder challenge, but won't cause frequent frustration thanks to the knowledge about the mechanics of the series. If you had played Human Revolution, you can choose the hard difficulty level (Give me Deus Ex). You won't have to worry about the encounters with enemies, and you will be able to handle it even if the quest doesn't go your way. If it's your first contact with the Deus Ex series, choose the normal difficulty level.
