Over time, the heat warpage had a residual affect and the door became permanently bowed along the lock edge. At peak summer temperatures, the hollow metal door became so hot that it warped. To make matters worse, the slab-sided building and the door were painted a dark color that absorbs heat. There was no awning or cover structure over this door because it was a secondary entrance. For example, take an exterior hollow metal door located on the east facing side of a poured concrete building. The placement of exterior doors plays a significant role in potential problems. With today's poured concrete buildings, solving a problem can be costly and time consuming. Poor construction can result in problems with door operation and air infiltration. They should be plumb, with solid jambs and doors that swing open and closed and latch without external resistance. By building condition, we are referring to its structural integrality in regards to the door openings. In addition to the doors, the condition of the building is also a significant factor in the operational life and a good indicator of the problems that may occur. Using these two examples, we show how the operational life of a door, opening and the attached hardware can be dramatically different. Commercial doors range from high-end decorative entry doors equipped with automatic door operators to alley or loading dock doors that get opened using a cart, fork lift or pallet jack.
