Do aluminium door handles require any special treatment during winter?

As a supplier of aluminium door handles, I often get asked about the special care these handles might need during winter. Aluminium door handles are a popular choice for many homeowners and businesses due to their durability, aesthetic appeal, and resistance to corrosion. However, winter conditions can present unique challenges that might require some attention to ensure the longevity and functionality of these handles.

Understanding Aluminium Properties

Before delving into winter - specific care, it's essential to understand the properties of aluminium. Aluminium is a lightweight metal that forms a thin oxide layer on its surface when exposed to air. This oxide layer acts as a protective barrier, preventing further oxidation and corrosion. In normal conditions, this makes aluminium door handles highly resistant to rust and degradation.

However, extreme cold and moisture can affect this protective layer. During winter, the temperature drops significantly, and there is often an increase in humidity due to snow and ice melting. These factors can potentially accelerate the wear and tear of the oxide layer on aluminium door handles.

Impact of Winter Conditions on Aluminium Door Handles

Cold Temperatures

Cold temperatures can cause the metal to contract. While aluminium has a relatively low coefficient of thermal expansion compared to some other metals, extreme cold can still lead to minor changes in its dimensions. This contraction might cause the handle to fit slightly differently in its mounting, potentially leading to loosening over time. If the handle is not properly secured, it can become wobbly and may even fall off, posing a safety hazard.

Moisture and Humidity

Moisture is one of the biggest enemies of metal objects during winter. Snow, ice, and rain can expose the door handles to large amounts of water. When water comes into contact with aluminium, it can start to break down the protective oxide layer. If the water contains salts (from de - icing agents on roads and sidewalks), the corrosion process can be even faster. Saltwater is highly corrosive and can cause pitting and discoloration on the surface of the aluminium door handle.

Frost and Ice

Frost and ice can accumulate on the door handles, making them difficult to grip. In some cases, the ice can expand within small crevices or joints in the handle, causing internal stress. Over time, this stress can lead to cracks or other forms of damage.

Special Treatment for Aluminium Door Handles in Winter

Regular Cleaning

Regular cleaning is crucial during winter. Use a mild soap and warm water solution to clean the door handles. This helps to remove dirt, salt, and other contaminants that can cause corrosion. Avoid using abrasive cleaners or scrubbers, as they can scratch the surface of the aluminium and damage the protective oxide layer. After cleaning, dry the handles thoroughly with a soft cloth to prevent water from sitting on the surface and causing rust.

Lubrication

Lubricating the moving parts of the door handle, such as the latch mechanism, is important. Cold temperatures can make these parts stiffer, and lubrication can help them move smoothly. Use a silicone - based lubricant, which is suitable for use on aluminium. Apply the lubricant sparingly to the appropriate areas, following the manufacturer's instructions.

Protection from the Elements

If possible, provide some protection for the door handles from direct exposure to snow and ice. You can install a door awning or overhang to shield the handles from precipitation. Additionally, you can use a waterproof cover or a thin layer of wax to create an extra barrier against moisture.

Types of Aluminium Door Handles and Winter Care

Interior Door Knobs

Interior Door Knobs are generally less affected by winter conditions compared to exterior handles. However, they can still be impacted by the dry air that is common in heated indoor spaces during winter. Dry air can cause the finish on the knobs to become dull or cracked. To prevent this, you can use a mild metal polish to maintain the shine of the knobs.

Aluminum Sliding Door Handles

Aluminum Sliding Door Handles are often exposed to the elements, especially if the sliding door is on the exterior of the building. These handles are more likely to accumulate snow and ice, which can make it difficult to operate the door. In addition to regular cleaning and lubrication, make sure to clear any ice or snow from the track and around the handle area to ensure smooth sliding.

Glass Door Knobs

Glass Door Knobs are a combination of glass and aluminium. The aluminium parts need the same winter care as other aluminium door handles. However, the glass part is more prone to cracking in cold temperatures. Avoid using excessive force when turning the knob, and if possible, keep the glass door in a temperature - controlled environment to prevent thermal shock.

Monitoring and Maintenance

Regularly monitor the condition of your aluminium door handles during winter. Check for signs of corrosion, such as pitting or discoloration, and for any loose or wobbly parts. If you notice any issues, address them promptly. Minor problems can often be fixed with simple repairs, but if the damage is extensive, it might be necessary to replace the handle.

Conclusion

In conclusion, while aluminium door handles are generally durable and resistant to corrosion, they do require some special treatment during winter. By understanding the impact of winter conditions on aluminium, taking proactive steps to clean, lubricate, and protect the handles, and regularly monitoring their condition, you can ensure that your door handles remain in good working order and maintain their aesthetic appeal throughout the winter months.
