Graf & Sons Garage Doors - As a door expert witness, I am called upon many times annually to gauge garage door injuries. Garage doors come in many sizes and shapes. Their functions range from fundamental security of a place to decorative concealment. Most doors might be broken down into several basic styles or categories. Typical contemporary garage doors for residential uses tend to be mostly of the overhead sectional variety. That fashion of the door comes in many shapes, materials, amounts of insulation, and also a wide array of appearance options.
They're built as a custom design to complement the decor of any building or available as a prefabricated kit. Commercial warehouse type setups often dictate higher security requirements. A great option for this particular security sort of door is the "roll up" style that resembles a roll top desk sort of door. This door may be made with a number of materials that may be as robust as the abutting walls, making forced entry through this opening very difficult.
Before, with managing an overhead garage door the greatest concern was the possible dangers associated with the springs used for balancing the door weight. These springs became loaded (tensioned) as the door was moved to the closed position. Unloading (releasing) of the stored spring energy occurred as the door was opened to the flat overhead situation.
One of the most dangerous aspects of the spring systems was that after a time frame, frequently without any care or inspection, the points of attachment of the springs would rust or become weak. This weakening of the springs or points of attachment would frequently lead to an inadvertent failure fling that is volatile the broken spring components over the garage, embed the spring or steel components to the garage walls, cars or other things in the route of traveling.
