The difference between industrial aluminum profiles and architectural aluminum profiles

Industrial aluminum profiles and architectural aluminum profiles are made of the same 6063 grade aluminum, meaning that their alloy composition and content are alike. Consequently, there are no differences in mechanical properties between these two types of profiles. Both share similar characteristics, such as weldability, thermal conductivity, surface treatment properties, corrosion resistance, and cutting capabilities. But despite these similarities, there are fundamental distinctions that set them apart.

1. Distinct Cross-Section Shapes

Industrial aluminum profiles typically exhibit symmetrical designs and tend to be more square in shape. In contrast, aluminum profiles for buildings are characterized by asymmetrical shapes that often feature a larger curvature and significant cantilevers. Additionally, industrial profiles tend to have more cavities, frequently displaying round holes throughout their structure.

2. Varying Wall Thicknesses

Generally speaking, industrial aluminum profiles possess a greater wall thickness compared to architectural profiles. Since the primary function of the latter in doors, windows, and curtain walls is decorative, they can afford to be thinner. On the other hand, industrial profiles are commonly employed in applications requiring structural integrity, such as equipment frames and brackets, thereby necessitating a thicker wall for enhanced load-bearing capability.

3. Variations in Surface Treatment Techniques

Typically, industrial aluminum profiles require only anodizing treatment, sometimes accompanied by a sandblasting process to achieve a matte finish. In contrast, architectural aluminum profiles can undergo various surface treatments, including spraying, electrophoresis, and wood grain transfer. The focus on aesthetics for architectural profiles results in a wider array of colors, while industrial profiles prioritize a clean and simple appearance, often limited to natural color oxidation or occasional black oxidation.

4. Quality Requirements Differ

The tolerances for shape and position in industrial aluminum profiles are typically stricter than those found in aluminum profiles intended for architectural use, reflecting higher surface quality demands. The clear oxide film produced through anodizing can reveal any surface defects immediately, emphasizing the need for meticulous quality control.
