How should garage doors be maintained in cold areas?

Since the winter in Northeast China is long and cold, most homeowners will choose a garage door with thermal insulation performance. This type of garage door is made of a variety of materials and double-layered, with insulation foam material in the middle, and can avoid the appearance of condensed water, and has very good strength. Most of them can reach the inner room through a tunnel. It can be said that it is a must-have for garages in Northeast China.
Fire doors are a kind of fireproof and heat-insulating facilities suitable for the openings of buildings, which play a certain role in design and installation technology. Fire doors are widely used in fire-proof partition areas of industrial and civil buildings, which can effectively prevent the spread of fire.
Some garage doors are roller shutter type, but roller shutter doors are easier to pry open. In addition to welding two angle irons near the garage door and adding two padlocks, many homeowners will install monitoring on it, and call the police in time if there is a problem.
Choose a mild and sunny day to paint. Climate conditions may have a great impact on the quality of exterior paint. At the same time, be sure to thoroughly clean the garage door before painting. Paint can only be started after it is completely dry. Choose the color you like. For most garage doors, light shades such as white, beige or pearl work best because they won't fade in the sun. It is recommended to prime the garage door before painting to ensure better results. Using a mild detergent and a soft brush, remove any corrosive chemicals or dirt from the garage door to prevent it from corroding the garage door or rusting or even twisting the garage door.
After cleaning, you can also check at a glance if the springs or hinges need repair. It is generally recommended to clean 3-4 times a year to ensure that the garage door is always in a healthy state. Electric garage doors have springs and chains to ensure that the door moves up and down easily. To ensure its proper operation, it is recommended to lubricate the key moving parts with spray oil on all springs, hinges, rollers and pivot points at least once a year.
Once a year, the garage door should be thoroughly inspected and any screws, nuts or bolts that may have loosened should be tightened. This is important to keep the garage door moving properly on the rollers. Using a detergent that does not contain corrosive substances, wipe the garage door track and carefully clean all exposed parts of the rollers. Remove all excess moisture. Then use a specially designed garage door lubricant or powdered graphite to keep the rollers moving smoothly and efficiently on the track. Metal doors will inevitably rust and lose paint over time; wooden doors will begin to darken and become rough over time. Buying a new door will cost a lot of money, so how to renovate the door? The easiest way is to repaint it.
