A commercial door can be as secure as possible and yet become frustrating to use if the hinges begin to lose the struggle against gravity.
Initially, the change is slight. The lower corner touches the threshold and the latch requires a bit more pressure in order to engage. A few months later, the employees are found to be pulling the door with greater effort, and customers might think that the lock is failing.
The hinges have to bear a great deal of stress because of the heavy commercial doors.
If frequent adjustments soon cease to remedy the issue, then a continuous hinge may provide a more durable means of supporting the door.
Why Commercial Doors Begin To Sag
Each time a door is opened, the load of the door acts on the hinge side of the frame. Commercial hinges of the standard type bear that load at a number of different mounting points.
After thousands of cycles the screws may loosen and the hinge parts may wear away. The door can then gradually become misaligned.
The issue becomes more apparent on large hollow metal doors or on aluminium storefront doors, and if the door also has heavy hardware then this places extra strain on the hinge side.
If the door drops a little bit, some of the other parts may fail to align properly.
Sagging Can Look Like A Lock Problem
How the door is aligned is closely related to how the lock operates.
The latch is constructed so that it enters the strike at a specific position; if the door sags then the latch might start to rub against the edge of the strike as a result. A deadbolt can also suffer from this issue.
Someone trying to use the door might notice resistance and assume the lock needs to be replaced; in fact, the lock could be working properly if the door is properly aligned.
Pressing the key or lever repeatedly doesn’t address the root cause; it may actually cause additional wear on hardware that was functioning properly before the door shifted.
Which is why when a locksmith is assessing a difficult commercial door he should examine the whole opening rather than focusing just on the cylinder.
What Makes A Continuous Hinge Different
A typical door has many separate hinges placed along the frame.
A hinge that is continuous covers almost the entire height of the door; rather than supporting the door at a small number of specific points, it spreads the load over a much larger part of the frame.
Broader support helps with heavy doors that repeatedly cause standard hinges to become misaligned.
Continuous hinges, also known as piano hinges, are often used for tough door applications. They come in several configurations to match different opening types.
For a business that deals with recurring sag, the change will create a more secure connection between the door and the frame.
When Adjustment May Still Be Enough
The fact is that a door which sags doesn’t necessarily require a new hinge system.
The hinges that are already in place may sometimes just require a bit of care; the loose screws can be tightened and minor misalignments can often be cured by making adjustments.
The condition of the frame matters just as much; installing new hardware on a damaged mounting surface won’t fix the basic structural problem.
A locksmith can inspect how the door sits in the opening and determine the source of the movement. If the existing hinges remain in good condition, an adjustment may restore proper operation without a larger repair.
Continuous hinges are more appealing when the same sagging problem keeps occurring or when the existing hinge points have undergone considerable wear.
Door Alignment Affects More Than Convenience
A heavy door is annoying, but the way the door is aligned has an effect on how reliably the opening stays secured.
When the latch barely enters the strike, the door may look shut even though it isn’t properly secured; employees may develop the habit of lifting the handle or pulling the door toward them before locking it.
The fact that those workarounds exist should serve as a warning.
The closer may also have difficulty when a door is misaligned since this causes extra resistance. A closer which has been adjusted to overcome that resistance might shut the door too vigorously once the hinge issue has been repaired.
By attending to the alignment first, the remainder of the hardware has a better opportunity to function as intended.
High-Traffic Entrances Deserve Extra Attention
A door that is used a few times a day shows much more different wear than one which is used in a busy storefront or office.
The more traffic there is, the greater the number of cycles that the hinges have to go through. After a while, small movements can become noticeable in the gaps beside the door.
Periodic inspections let you detect changes before the door starts to fail to latch.
If employees notice that a door suddenly seems heavier or requires an extra push to close, it may be advisable to check the hinges at an early stage in order to prevent further damage.
