Rewritten title: Unveiling the Causes: Exploring the Factors that Lead to Deformation of Aluminum Panels

Aluminum panels are renowned for their versatility and durability, making them a popular choice in various industries. However, as with any material, there are certain factors that can lead to their deformation. In this article, we will explore the main reasons behind the deformation of aluminum panels, shedding light on the causes that often go unnoticed. Join us in unraveling the mysteries behind this common occurrence and gain insights into effective preventive measures.

The Deformation of Aluminum Panels: Causes and Preventive Measures

Aluminum panels are widely used in building curtain wall designs due to their numerous benefits. However, they are prone to deformation during long-term use. While this phenomenon is not common, understanding the main causes is essential to prevent it. In this article, we will delve deeper into the factors responsible for aluminum panel deformation, emphasizing the significance of taking necessary precautions to maintain their structural integrity.

Rewritten title: Unveiling the Causes: Exploring the Factors that Lead to Deformation of Aluminum Panels 1

1. Insufficient Structural Support:

One of the primary reasons for the deformation of aluminum panels is inadequate structural support. When manufacturers opt for low-cost production methods, they may eliminate side and center ribs to save on expenses. However, the absence of these reinforcement elements weakens the overall strength of the panels. Consequently, under the influence of wind pressure and air expansion, the aluminum panels deflect from the inside outwards, resulting in increased size and deformation. To prevent this, it is crucial to ensure that proper side and center ribs are installed during the manufacturing process, adhering to project requirements.

2. Thermal Stress:

Aluminum panels fixed firmly to the curtain wall structural frame can experience deformation due to thermal stress. In regions with significant temperature variations, the impact of solar radiation on darker aluminum panels can be substantial. During low-temperature seasons like early spring and late autumn, the thermal expansion value per meter of these panels varies greatly. When aluminum panels and frames are exposed to sunlight, the temperature difference can reach up to 80°C, leading to considerable linear expansion differences. If the aluminum panels are secured using screws without allowing for the release of thermal stress, the panels yield and deform outward due to air and temperature effects. To mitigate this issue, it is crucial to ensure that the aluminum panels are installed in a manner that allows for the release of thermal stress, reducing the risk of deformation.

3. Assembly Stress:

Another significant reason for aluminum panel deformation is the stress that occurs during the assembly process, particularly when panels and edge ribs are joined together. To address thermal stress deformation, manufacturers often add a rib frame around the unit panel, especially with aluminum-plastic composite panels. However, deviations in the folding of plate grooves and deviations in the assembly of the side rib profiles into the frame can occur. This results in forced assembly, leading to stress on the surface of the board and deformations in the edge ribs or compression deformation on the board surface. As a consequence, the panels deform outward under the influence of temperature and air expansion forces. To prevent this, proper attention should be given to precise assembly techniques and ensuring a perfect fit between the panels and the rib frame.

The deformation of aluminum panels can be attributed to factors such as insufficient structural support, thermal stress, and assembly stress. Identifying these issues and taking appropriate preventive measures is crucial in maintaining the integrity and durability of aluminum panels. Proper installation techniques, regular maintenance, and the selection of appropriate aluminum alloys are instrumental in minimizing the risk of panel deformation. By understanding the causes and implementing effective preventive measures, we can ensure the longevity and optimal performance of aluminum panels in various industries.
