Bars usually function as a security mechanism.
A fence is a structure made up of rods or bars that are intertwined in some way. It may be an instrument of security , insulation or ornamentation . For example: “We have to change the window grille: it is very rusty,” “A grille separated the sick from the visitors,” “I really like the decorative grille you installed next to the entrance door.”
Protective bars are the most popular. Built with solid materials that are difficult to break, their purpose is to prevent unauthorized people from entering or leaving an area.
Within the field of hydraulic engineering , on the other hand, bars are used to protect those installations or devices that can be damaged by certain residues present in the water . In this case, the grate acts as a filter .
Different types of bars
In some prisons , cells have bars so that inmates do not escape. In this case, the mobility of the prisoners depends exclusively on the guards, who are in charge of opening or closing the bars. It is worth mentioning that in certain more modern prisons , it is normal for the cells to be more similar to normal rooms, although with very thick doors that are resistant to any attempt to break them down.
In homes, bars often serve as an additional security mechanism. They are often installed on windows to make it impossible for an intruder to force their way into the house. They can also be installed at the entrance door so that the house has double security (whoever wants to enter must not only open the door, but also the gate).
A fence can have different ornamentations.
The sharp tips
A common characteristic of many models of fences is the presence of sharp points at the upper end , as a warning to potential intruders of the danger of injuring themselves if they slip while trying to climb and jump into the property . This can also be harmful to animals that want to get into houses without permission, although they usually have greater agility and, of course, are much smaller in size than a human being.
This design decision is very violent and unnecessary for many people, since it can also cause harm to the homeowners themselves in an emergency in which they are forced to jump to escape or enter by force, which can occur in the middle of a fire, a seismic movement or an attack by criminals who are already in the house.
Bars and security
Security is one of those controversial topics that can be approached from many different perspectives, and that do not seem to have a single solution, since they depend on various factors. One of them is the culture and social situation of each country and city; In some places in the world, insecurity in the streets is so worrying that residents are forced to pass through the doors of their homes several times before deciding to enter, to verify that there is no one watching them and waiting for the moment to enter. steal.
In a site with these characteristics, it is expected that homes will have bars on their doors and windows. On the other hand, there are still cities where robberies and attacks in the streets are not so frequent, and it is even possible to leave the doors open during the day without fearing that someone will enter by force .
A Buenos Aires city
La Reja , finally, is the name of a city located in the Province of Buenos Aires ( Argentina ), forming part of the Moreno District .
Its name derives from a grocery store that existed at the end of the 19th century near the current Sarmiento railway station, since this type of establishment always had a grill over the counter to protect the clerk from criminals.
