Side-hung windows, commonly used in residential and commercial buildings, require robust and durable hinges to withstand regular use and maintain optimal functionality. The materials employed in these hinges play a crucial role in ensuring longevity and performance. This article explores the various materials used in side-hung window hinges and their respective properties that contribute to durability.

Stainless Steel

Stainless steel is a highly durable material known for its exceptional resistance to corrosion and rust. It is often used in side-hung window hinges due to its ability to withstand moisture and harsh environmental conditions without deteriorating. Stainless steel hinges are robust, can withstand heavy loads, and maintain their structural integrity over time.

Aluminum Alloys

Aluminum alloys offer a lightweight and corrosion-resistant alternative to stainless steel. They are commonly used in side-hung window hinges due to their strength, durability, and resistance to weathering. Aluminum alloys are particularly well-suited for applications where weight reduction is a concern, such as in large or complex window systems.


Brass is a non-ferrous alloy of copper and zinc with excellent durability and corrosion resistance. It is often used in side-hung window hinges due to its ability to withstand both wear and tear as well as exposure to moisture and heat. Brass hinges are relatively strong and can provide a long service life in various indoor and outdoor applications.


Polyamide is a type of plastic with exceptional toughness and durability. It is commonly used in side-hung window hinges as a non-metallic alternative to metal materials. Polyamide hinges are lightweight, resistant to corrosion and chemicals, and can withstand extreme temperatures. They are also self-lubricating, reducing maintenance requirements.

Finishing and Coatings

In addition to the base materials, finishes and coatings play a significant role in enhancing the durability of side-hung window hinges. These treatments provide additional protection against corrosion, wear, and weathering.

Electroplating: Electroplating is a process of depositing a thin layer of metal (such as zinc or nickel) on the surface of the hinge. This process enhances corrosion resistance and protects the hinge from rust.

Powder Coating: Powder coating involves applying a dry powder to the hinge’s surface and then curing it under high temperature. This coating provides excellent resistance to wear, abrasion, and harsh environmental conditions.

Anodizing: Anodizing is an electrochemical process that creates a protective oxide layer on the surface of aluminum hinges. This layer enhances corrosion resistance and improves surface durability.
