Winter Door Failures: Why Extreme Cold Breaks Commercial Entrance Systems

In Canada, winter can be severe, and that has a direct effect on everything, including the exterior of the house. Commercial setup owners sometimes encounter door failure issues. What if you find the store opening time is approaching, but the main door will not budge, even an inch? This is not chance and coincidence! It is physics, chemistry, and engineering limits clashing. 

Extreme cold affects metals

When the mercury keeps sliding, that affects metals. Both steel and aluminum become more brittle as temperatures drop. When the temperature drops well below freezing, materials that are usually somewhat flexible become rigid. A steel door frame can shrink measurably in extreme cold. That can be in millimeters, but still cause door movement hassles. 

What if your shop has an aluminum door? It can be worse than steel! Aluminum expands and contracts more than steel with temperature changes. In places like Calgary, where chinooks can lower temperatures by as much as 30 degrees, aluminum doors fare worse. 

The hydraulic fluid issue crops up

Most automatic door closers use hydraulic fluid, and in extreme cold, that does not work well. Hydraulic fluids thicken as temperatures drop. That affects door movements adversely. The changes may not be drastic sometimes, but you will spot the signs of doors acting up.

Many commercial setup owners observe their doors not closing as they should. That is the beginning of the problem. Some people also see smooth-closing doors suddenly slam hard. Swing doors may get stuck halfway, and you may need to use extra force to open them manually. 

The problem can be more serious in vestibule systems where one door faces extreme exterior cold while another faces hot interior air. When you face such door problems, hiring veteran entities like Doorway Dynamics – Commercial Door Repair becomes necessary. 

What do commercial door repair entities do?

Top commercial door repair and maintenance companies look into some factors to resolve such issues:

• They check the door seals and weather stripping carefully. In extreme cold weather, these do not remain flexible. It will be better to replace worn-out items with Premium cold-weather seals.
• Motion sensors and presence detectors may not work well in freezing weather. This is true for both infrared- and microwave-based units. 
• Automatic door operators use an electric motor, and they are battery-driven. Most automatic doors have a battery backup for power failures. These batteries lose their capacity in cold weather. This leads to door operational issues. 
• Door parts and hardware can also crack or malfunction in icy cold weather. 

Professional door repair and maintenance companies install cold-weather-rated weather stripping, check battery capacity, apply high-quality lubricants, and thoroughly test automatic door systems. 

Summing it up

Commercial doors in Canada operate in extreme cold, which affects their performance. Ideally, you should watch for signs of a door problem. When these signs crop up, look for suitable repair service providers. Pick one with enough good reviews and a large client base. Working with the best always has its advantages. They use the latest equipment and are well aware of what needs to be done.
