In regions with extreme weather conditions, choosing exterior door handles that can withstand the elements is crucial to ensure the longevity and functionality of your doors. UPVC (unplasticized polyvinyl chloride) is a highly durable material that is commonly used for exterior door frames and window frames due to its exceptional resistance to weather conditions, UV rays, and corrosion. When selecting UPVC exterior door handles, there are several key factors to consider to ensure optimal weather resistance.

Material Composition

The material composition of the door handle is paramount in determining its weather resistance. High-quality UPVC handles are manufactured using a blend of virgin and recycled UPVC. Virgin UPVC provides strength and durability, while recycled UPVC enhances its eco-friendliness. The combination of these materials ensures that the handles can withstand extreme temperatures, moisture, and UV radiation without becoming brittle or fading.

Design and Construction

The design and construction of the door handle also influence its weather resistance. Look for handles with a solid, one-piece construction, as multi-piece handles have more joints and therefore potential weak points where moisture can penetrate. The handle should have a smooth, seamless surface without any nooks and crannies where water and dirt can accumulate. Additionally, the handle should have a secure grip that is comfortable to use, even in wet conditions.

Finish and Coating

The finish and coating of the door handle provide an additional layer of protection against the elements. Choose handles with a high-quality powder-coated or anodized finish. Powder coating involves applying a fine layer of paint to the handle and then baking it at high temperatures to create a durable, weather-resistant finish. Anodized finishes involve chemically treating the handle to create a hard, corrosion-resistant surface. These finishes prevent rusting, fading, and peeling, extending the life of the handle.

Seal and Gasket

The seal and gasket around the base of the door handle play a crucial role in preventing moisture from entering the door. Look for handles with a rubber or silicone seal that creates a tight fit between the handle and the door frame. The gasket should be durable and UV-resistant, ensuring that it can withstand the elements without cracking or deteriorating.

Locking Mechanism

The locking mechanism of the door handle is another important consideration. Choose handles with a robust locking mechanism that is resistant to tampering and forced entry. The lock should have a smooth operation and be easy to use, even in harsh weather conditions. Additionally, consider handles with a concealed lock, as exposed locks can be vulnerable to corrosion and freezing.
