Fauna Door Handles September 19th, 2017 - 06:26:06
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.
The second facet of the design of door handles is that they should be simple in design both in shape and size so that they are do not protrude and catch people as they pass by. The shape should be such that it is easy to operate, in most kitchens they work by a straight pull with the door being held in position by a magnetic door catch and the design should reflect this. The pattern should not include grooves or crevices where dirt can collect and cause problems.
The quality of the knobs is important since handles are used regularly. There are various materials used to make door handles. Stainless steel is one other most durable materials for door furniture knobs. There are both satin stainless and polished stainless knobs. There are different grading of the stainless steel and you can get an average grade for your household use. Chrome and brass are also durable materials for door handles. Other knobs such as glass are delicate and may be inappropriate for exterior doors. Though they are very beautiful and classy, they may easy be dirtied and will look bad if not cleaned and shined. Wood knobs are also available. They may not be as durable as the steel handles but they are much cheaper. Besides the material used in making the door furniture handles, you should also be keen to buy knobs from a reputable company to be guaranteed of durability and quality.
There are two types of handles, when it comes to general use: external or outdoor handles which are utilized on all main entrances to the home, be it front door, back door, side door or service door; and internal handles which are used for the doors inside the house such as bedroom doors and toilet doors. One of the most popular broad types of external door handles is the lever type, which is commonly used in European homes. External latches are normally bigger as they frequently come with key-in locks for security, and are called lever lock handles. Indoor handles (or lever latch handles) are smaller, as they come without locks, and key-in locks are normally installed separately on the door. There are also external handles with combined door knockers, a very practical alternative when your electric door buzzer is out of order.
