Many people wonder why on earth people would place a security barrier around the perimeter of commercial property. The entire reason that you open a business is to get strangers to come to the place and buy the goods you have for sale. If you have services for hire then you want clients to come to the establishment and hire you. A security barrier seems to discourage the presence of people other than the employees and owner of the establishment.
A security barrier around an establishment that sells items that are stored outside will make sense to almost everyone. The fencing is to keep unauthorized people from coming onto the property and walking away with merchandise without paying for it. It also keeps children and pets from being able to wander onto the property unsupervised and become injured by any of the materials the establishment has stored there. Most people do not question fencing around these businesses.
A security barrier around a business that provides service for the merchandise of others should also make good sense to the majority of people. If the establishment services or repairs things like cars, large appliances, or other things that are too large to store indoors you will want to provide as much protection to the property of your customers as you can. This will make people feel better about leaving their belongings in your care and it will make your liability insurance rates be cheaper. Theft deterrents like fire safety equipment can lower the amount you pay for insurance.
When you see a security barrier in place around a business that does not have things outside then these fences may not make sense to the average person. Once again you have to consider the insurance that commercial property has to have. If people are on commercial property and they trip or fall because of something that was on that property then they can sue the owner for any and all damages they sustain. That lawsuit can cover the medical costs of their injuries at the time of the accident and their medical costs related to the injury in the future. It can also cover any time they lose from work and it covers the pain and anguish they suffer. You also have to face the fact that there are individuals that make a living by lying and cheating. Placing a security barrier around the property stops the individuals from being able to claim that an injury occurred on commercial property when the owner or employees of the business were not present to witness the accident.
Unfortunately times have gotten so bad that people are actually stealing parts off of central air and heating units to sell as scrap metal. Copper brings a very high price at the salvage yard and people have actually begun to steal the copper tubing and the coils from these units. Almost all commercial properties including churches have these types of units to heat and cool the interior of the buildings. A security barrier simply protects the establishment from thefts like these.
