Standard Double Garage Door Opening Size - As a door expert witness, I'm called upon many times a year to judge garage door harms. Garage doors come in many shapes and sizes. Their functions vary from basic security of a place to concealment that is cosmetic. Most doors could be broken down into groups or several basic styles. Typical contemporary garage doors for residential applications have a tendency to be mostly of the overhead sectional variety. That fashion of the door comes in many shapes, materials, amounts of insulation, and a wide array of look options.
They are built as a custom layout to complement the decor of any building or available as a kit that is prefabricated. Commercial warehouse sort installations generally dictate higher security requirements. A good option for this particular security type of door is the "roll-up" design that resembles a roll top desk type of door. This door can be produced with various materials which can be as solid as the abutting walls, making forced entry by means of this opening very difficult.
In the past, with operating an overhead garage door, the greatest concern was the possible hazards related to the springs useful for balancing the door weight. Pre mid-1960's garage door setups generally relied upon a set 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.
Some of the most dangerous aspects of these spring systems was that after a time frame, often without any care or inspection, the points of attachment of these springs would corrode or become feeble. This weakening of the springs or points of attachment would often lead to an inadvertent explosive failure fling the spring that is broken parts around the garage, embed the spring or steel parts into the garage walls, alternative items in the road of traveling or cars.
