Sliding door handles, particularly those used on external doors, are exposed to a wide range of harsh weather conditions. To ensure their functionality and durability, it is essential to utilize weather-resistant materials in their construction. This article explores the various materials that possess the necessary properties for these handles, providing insights into their advantages and applications.


Aluminum is a lightweight and strong material with excellent resistance to corrosion and wear. It is commonly used in the production of sliding door handles due to its ability to withstand extreme temperatures, UV radiation, and salt spray. Aluminum handles are low-maintenance and can be anodized or powder-coated to enhance their aesthetics and protective properties.

Stainless Steel

Stainless steel is another popular choice for external sliding door handles. Known for its exceptional strength and durability, stainless steel is highly resistant to rust and dents. It is also easy to clean and maintain, making it ideal for high-traffic areas. However, stainless steel handles can be more expensive than other materials.

Zinc Alloys

Zinc alloys, such as Zamak, offer a combination of strength, durability, and corrosion resistance. They are often used in the production of low-cost sliding door handles, providing a suitable balance between functionality and affordability. Zinc alloys can be plated or painted to enhance their appearance and protect them from the elements.


Polycarbonate is a thermoplastic material known for its exceptional impact resistance and weatherability. It is highly resistant to UV radiation, temperature extremes, and chemicals. Polycarbonate handles are lightweight and translucent, making them a suitable choice for applications where transparency is desired. However, they may be less durable than metal handles and prone to scratching.

Composite Materials

Composite materials, such as fiberglass reinforced plastic (FRP), combine the properties of multiple materials to enhance their performance. FRP handles are lightweight, durable, and weather-resistant. They can be molded into complex shapes, providing design flexibility and customization options. FRP handles are also low-maintenance and resistant to chemicals and solvents.

Selection Considerations

When selecting weather-resistant materials for external sliding door handles, it is important to consider the following factors:

– Exposure to Elements: Determine the specific weather conditions that the handles will be exposed to, such as temperature extremes, UV radiation, salt spray, and humidity.

– Usage Frequency: Consider the frequency of use and the potential for wear and tear. High-traffic areas require durable materials with exceptional wear resistance.

– Aesthetics: The appearance of the handles should complement the overall design of the external door and surrounding area.

– Cost: Balancing the desired level of durability and weather resistance with budgetary constraints is essential.


The selection of weather-resistant materials for external sliding door handles plays a crucial role in ensuring their functionality, durability, and aesthetic appeal. By understanding the properties and applications of various materials, such as aluminum, stainless steel, zinc alloys, polycarbonate, and composite materials, it is possible to choose the most suitable option for specific requirements. By considering factors such as exposure to elements, usage frequency, aesthetics, and cost, it is possible to invest in durable and aesthetically pleasing external sliding door handles that will withstand the challenges of any weather condition.
