Exploring the Differences Between Standard and Curved Aluminum Extrusion

Aluminum profiles play a vital role in modern construction and industry, where they are used in a wide range of applications from window frames and door frames to mechanical components and electronic housings. Not all aluminum profiles are the same: there are significant differences between standard and curved profiles that can have a significant impact on their use and performance.

Standard aluminum profile

Standard aluminum profiles have a straight-line cross section, and they are usually manufactured by pressing aluminum rods through a mold. This method gives them a uniform thickness and a smooth surface. Standard profiles offer the advantages of high strength, durability and lower cost, but they have limitations in complex shapes or bending applications.

Curved aluminum profile

Curved aluminum profiles, also known as bent or formed profiles, are formed by bending or deforming standard profiles. This process can be done by a variety of methods, including hot bending, cold bending, and roll bending. Curved profiles have a flexibility that standard profiles cannot achieve, allowing them to form a variety of shapes and curves.

Compare

Shape: Standard profiles have a straight section, while curved profiles can adopt a variety of shapes and curves.

Manufacturing method: Standard profiles are manufactured by pressing out, while curved profiles are manufactured by bending or deforming standard profiles.

Strength: The bending process can reduce the strength of aluminum profiles, especially if the bending radius is too small.

Accuracy: Standard profiles have higher accuracy, while curved profiles may have slightly lower accuracy, depending on the bending process.

Cost: Curved profiles are generally more expensive than standard profiles due to additional manufacturing steps.

Application

Standard profiles: window and door frames, structural components, industrial machinery and electronic housings.

Curved profiles: Automotive and aerospace components, architectural arcs and decorative elements, medical devices, and other applications requiring complex shapes.

Standard and curved aluminum profiles each have their own unique advantages and uses. Standard profiles offer higher strength, lower cost and higher accuracy, while curved profiles offer a wider choice of shapes and curves for more complex applications. Understanding these differences is crucial to choosing the best aluminum profile for a particular project.
