3003 aluminum sheets are widely employed in curtain wall construction, primarily in two distinct temper states: 3003 H14 and 3003 H24.
The "H" designation signifies the cold work hardening condition, while the subsequent numbers indicate different degrees and types of cold work hardening.
Specifically, H14 represents a state of pure work hardening, referring to the final cold-rolled product without any additional heat treatment. This state offers relatively high hardness, strength, and tensile strength, but with lower ductility.
On the other hand, H24 indicates a state of work hardening followed by incomplete annealing. The final step in the product's processing involves heat treatment, resulting in a product that exhibits low hardness and high tensile strength.
When it comes to 3003 aluminum sheets, 3003 H14 typically indicates a tensile strength greater than 140MPa, while 3003 H24 represents a product with a strength greater than 240MPa. These distinct properties allow for flexible use cases depending on the specific requirements of the curtain wall application.
3003 curtain wall aluminum sheet is the outer wall of a building. It is a lightweight wall of large high-rise buildings and has a certain decorative effect. Aluminum curtain walls usually use 1060 aluminum sheet, 1100 aluminum sheet, and 3003 aluminum sheet as base materials, with various thicknesses such as 1.5/2.0/2.5/3.0/4.0mm. They are lightweight, corrosion-resistant, environmentally friendly, and have a long service life. They are well received Favored by users.

As the most widely used rust-resistant aluminum, 3003 aluminum sheet stands out as a preferred material for outdoor curtain walls. It offers superior strength and surface smoothness compared to 1-series aluminum alloys, while being significantly more cost-effective than 5-series aluminum alloys. Although it may not be as suitable as 5052 aluminum sheet for marine applications, its corrosion resistance is ample for general outdoor curtain wall use cases.
Composition of 3003 curtain wall aluminum sheet
Aluminum curtain walls are made of high-quality aluminum alloy sheets, with commonly used thicknesses of 1.0, 1.5, 2.0MM, and 3003. Its structure is mainly composed of embedded sheets, panels, reinforcing ribs and corner codes. The embedded sheet is connected to the structure through bolts and is stressed. The corner codes can be directly bent and stamped from the panel, or they can be riveted on the small side of the panel.
The reinforcing ribs are connected to the welding screws behind the panel (the screws are directly welded on the back of the panel), making it a solid whole, which greatly enhances the strength and rigidity of the aluminum alloy single panel curtain wall and ensures long-term use Smoothness and wind and earthquake resistance. If sound insulation and insulation are required, efficient sound insulation and insulation materials can be installed on the inside of the aluminum sheet.
