Painting Revolving Doors
Revolving doors were first patented in Germany in 1881 by H. Bockhacker and were touted as the door without a draft of air. These elegant entrances are often installed in prestigious buildings such as hotels or grand apartment blocks. In fact in 1899, Rector’s restaurant in Manhattan boasted the installation of the first revolving door in the world. Since then the penchant for revolving doors has become a worldwide phenomenon as has painting revolving doors.
A revolving door mechanism usually includes up to four doors (known as wings or leaves) that are attached to a central rotating shaft. It is worth noting that any of the metal panels can be re-sprayed electrostatically to protect them and to improve their appearance. These doors rotate within a glass enclosure which serves as an airlock to reduce draughts and therefore save energy.
With other types of entrances, every time a door is opened convection currents cause heat loss in winter and gain in warmer months. However, the airlock in the circular enclosure helps maintain an even temperature in the foyer of a building. This is why revolving doors are usually found in entrances to properties with a high footfall such as shopping centres, offices, banks and museums where the design can ensure thermal insulation.
Large scale units are also available and are often placed in stations and airports. Here, revolving doors with a large diameter can be used easily by people with pushchairs or those with cumbersome luggage. Furthermore, they are useful for security purposes as they can be constructed to only revolve in one direction. This design feature prevents passengers bypassing security checks. One-way traffic mechanisms can also stop service uses from avoiding paying for admission in sports arenas, theme parks and concert halls.
With a high volume of human traffic, safety is paramount, so revolving doors can be automatic and motorised or manual and both types can be kept permanently open for emergency exits if necessary. Most revolving doors are collapsible in that they can transform into a central partition at 180 degrees which enables the use of both sides for a quick exit or for moving long objects in and out of a building. Creating an entrance that needs to be accessed easily is not only a crucial safety feature, it is important for many commercial premises that have regular use. Consequently, revolving doors also suit health centres and supermarkets.
Ergonomic advantages are one of the main reasons businesses choose to install revolving doors. They can provide an easy entrance for people with reduced mobility, help maintain an even interior climate and can solve security problems. Their function is superior in many ways, but they also add grandeur to any building. Revolving doors are available in a range of styles to suit various architectural designs. They are often manufactured in glass and powder coated aluminium or stainless steel with either a brushed, polished or anodised finish. Over time of course, the perfect surface can deteriorate, but a professional paint spraying company can easily refurbish them. Any type of finish can be achieved by re-spraying the doors. Metallic coatings such as gold, silver or copper colour can be spray applied to wings or leaves or a range of colours are available to match the branding of a company.
If revolving door spraying is carried out by an experienced team with specialist knowledge of electrostatic paint spraying and working in challenging environments, then the building can carry on functioning as normal. Businesses that see a high footfall are demanding sites to work on, so any refurbishments have to include a high standard of health and safety measures. When painting existing revolving doors, a good re-coating company will only spray the metalwork that is needed because everything else will be masked off. A vast range of finishes are available to compliment the classic, timeless design of these entrances and the business they represent, so they can easily look as wonderful as they did when new.
