Product Introduction
Our Aluminum Alloy Hinges, designed specifically for T - slot aluminum profiles, are a top - tier choice for applications demanding high - performance hinge solutions. These hinges feature a unique construction where the hinge leaves are crafted from high - quality aluminum alloy, while the heart shaft is made of stainless steel. This combination of materials results in a hinge that is both lightweight and incredibly durable.

Product Parameters
Material: Aluminum Alloy + Steel
Color: Silver/ Black

Product Features
High - Quality Material Construction
Aluminum Alloy Hinge Leaves: The aluminum alloy used for the hinge leaves offers several advantages. Aluminum is known for its lightweight nature, which makes the hinges easy to handle during installation. At the same time, it provides excellent corrosion resistance, ensuring that the hinges can withstand various environmental conditions. The alloy also has sufficient strength to support the weight of heavily loaded doors and lids.
Stainless Steel Heart Shaft: The stainless - steel heart shaft is the core of the hinge's functionality. Stainless steel is renowned for its high tensile strength and resistance to rust and corrosion. This ensures smooth rotation of the hinge over an extended period, even under heavy use. The shaft's durability also contributes to the overall longevity of the hinge, making it a reliable choice for long - term applications.

Suitable for Heavy - Load Applications
Designed with precision, these hinges are engineered to handle the weight of heavily loaded doors and lids. Whether it's a large industrial door in a factory or a heavy - duty lid on a storage container, our Aluminum Alloy Hinges can provide the necessary support and smooth operation. The robust construction of the hinge leaves and the strength of the heart shaft work in tandem to ensure that the hinge can withstand the stress associated with heavy loads without deformation or failure.

Durable Metal Design
The overall metal design of the hinge is built to last. The combination of aluminum alloy and stainless steel creates a hinge that is not only strong but also resistant to wear and tear. The metal components are carefully crafted and assembled to provide a seamless and reliable hinge mechanism. This durability means that the hinges require minimal maintenance over their lifespan, reducing the cost and effort associated with replacing or repairing hinge components.

Product Advantage
Exceptional Load - Bearing Capacity
Our Aluminum Alloy Hinges stand out for their ability to support heavy loads. This makes them an ideal choice for industrial, commercial, and even some residential applications where large and heavy doors or lids are involved. The high - quality materials and precise engineering ensure that the hinges can handle the weight, providing a safe and reliable solution for door and lid operations.
Long - Term Reliability
Thanks to the corrosion - resistant properties of the aluminum alloy and stainless steel, these hinges offer long - term reliability. They can withstand harsh environmental conditions, such as exposure to moisture, chemicals, or extreme temperatures, without losing their functionality. This reliability is crucial in applications where hinge failure could lead to safety issues or operational disruptions.
Easy Installation
Despite their robust construction, the lightweight aluminum alloy hinge leaves make these hinges easy to install. The design is compatible with T - slot aluminum profiles, allowing for a straightforward installation process. Whether you are a professional installer or a DIY enthusiast, you can quickly and securely attach these hinges to the profiles, saving time and effort.
