In the past the biggest concern with operating an overhead garage door was the potential risks associated with the springs used for balancing the door weight. Pre mid 1960 s garage door installations typically relied upon a pair of stretched (tensioned) springs to assist the operation of the garage door pivoting hinges. These springs became loaded (tensioned) as the door was moved into the closed position. Unloading (releasing) of the stored spring energy occurred as the door was opened to the horizontal overhead position. One of the most dangerous aspects of these spring systems was that after a period of time often without any maintenance or inspection the points of attachment of these springs would rust or become weak. This weakening of the springs or points of attachment would often lead to an inadvertent explosive failure flinging the broken spring components across the garage embedding the spring or steel components into the garage walls cars or other items in the path of travel. Unfortunately sometimes people were in the path of travel of these explosive occurrences. As these springs failed as an attempted safeguard some manufacturers devised a "caging" system for the springs. These cages were retrofitted onto the stretched springs in an attempt to capture the parts that would release if a failure occurred. While these caging devices were helpful they were not completely effective. Some of these spring devices are still in use today. Whenever this condition exists or the quality of garage components are questionable a qualified professional service technician should be consulted.
Apart from steel and wood vinyl garage doors are also getting popular nowadays. Vinyl garage gates are rustproof and are more resistant to scratches than their steel counterparts. A vinyl garage gate is not usually available off the shelf. It usually takes a lead-time of 2-4 weeks. A vinyl garage door has the same exterior style and insulation options as a steel garage door. With environment consciousness pervading far and wide people are seeking environment-friendly garage door materials. These environment-friendly garage doors are made up of recycled wood. These garage doors can be painted and have insulation facilities.
In response to the inherently dangerous old style garage spring issues as above a newer and safer system for opening the overhead garage door was created. The idea was to transfer the load or weight of the door via a cable and pulley system to a vertical rod now equipped with a torsion (twisted) spring. This type of spring is installed with specialty hardware and bolts to a fixed plate at one end while the entire spring is installed around a horizontal pipe. This load balancing device is normally installed directly over the header of the garage opening. Using appropriate cables connectors and pulleys the weight of the garage door is transferred into the torsion spring system. The difference between the old style stretched spring and the newer torsion spring is the way that the spring energy is stored. With the old style stretched spring the energy is stored and released by pulling on the spring or returning the spring to its un-stretched condition. With a torsion type of spring the energy is imparted or removed by rotating the spring clockwise or counter clockwise depending upon the direction of usage. With professional installation the complete loading of the torsion spring is controlled by the garage installer and is determined by the weight and size of the garage door that it is operating. When this type of torsion spring fails it remains attached and intact to the location on the horizontal control rod where it was mounted. I have not heard of or seen any torsion spring fly across a garage creating injury from failed components as with the stretched older style garage door springs. This is not to say that injuries have not occurred with the torsion style spring. The installation of this type of spring is generally safe when left to a trained garage door installation professional. Severe and serious injuries have occurred when untrained unqualified individuals have attempted to install or service this type of spring. In most installations a warning tag is left attached adjacent to the torsion spring when the garage door is installed. This tag warns of the danger associated with the stored energy of this spring and alerts untrained individuals to not attempt any repair adjustment or to even touch the spring and associated hardware. When the label that should be attached to this spring becomes damaged is removed or tampered with it is important that a new warning label be reattached immediately to show the dangers of this spring tension
In 1912 an architect created "a new type of outbuilding". The garage which comes from the French word garer- to shelter or protect was invented. The first garage door was essentially a barn door. It was a double door attached to the garage with strap hinges that opened outward. They had the appearance of a basic shed and were subjected to heavy wear and tear. The hinges got rusty and squeaked and the screws would bend and eventually fall out. Snow made it difficult to open and close the doors as well.
In the past little attention was given to the aesthetic appeal of the garage. It was there merely to keep the family car safe from harsh elements outside. A simple attachment to the house that looked like a box was enough to be called a garage. However homeowners have come to realize that keeping the costs low when constructing a garage can greatly affect the overall visual appeal of the house. Besides a big garage that serves multiple purposes can put the extra space on the property to good use.
You may be used to installing doors in your house but garage doors whether they are automatic or manual are a far more difficult task. Installing a garage could be dangerous as well so it is strongly suggested to get a professional repairman to do your installation. These professionals will tell you that manual door installation is simpler compared to automatic door installation. It all depends on your preference. If you want heavy garage doors this would require automatic operations as they would necessitate enormous strength to lift. Manually operated garages are a lot lighter.
