Door Handles. Monday , November 20th , 2017 - 05:01:02 AM
As door handles easily catch germs and bacteria because of the variety of individual hands that touch them in the course of a day, it is important to consider the materials used. It is believed that certain materials like brass, copper and silver discourage the growth of bacteria and germs through some kind of electro-chemical effect; while other materials like aluminum, stainless steel, glass and porcelain do not have the same action. However, this belief has remained just that... a belief: and studies have not been extensive enough to confirm or disprove this possible effect, except in the case of silver. Hospitals in particular are experimenting with handle materials as they continue their fight against infectious disease within their wards.
When considering the handle, you should also consider its security especially it it is for an exterior doors. For home owners, it is important to select a knob with a quality locking system. A locksmith can assist in identifying door furniture handles that provide a decent amount of security for the people living in the house. Some door handles may come interconnected to the security system of the house to alert surveillance when the knob is operated when the alarm system is switched on.
When you consider that some 120 million doorways exist in the United States alone and another two million are installed each year, you can only imagine the vast number of door knobs. Going back in history, doors were initially made from textiles and animal hides. However, during the ancient Mesopotamia and Egyptian era, wooden doors were developed. Soon, materials for making doors expanded to include stone, glass, metal, and even paper.
