Mill finish aluminum coil refers to the aluminum coil formed after rolling or milling during the aluminum processing process without any subsequent surface treatment or coating. This aluminum coil shows the original surface state of aluminum. In some cases, the mill finish surface treatment can provide good adhesion and is suitable for subsequent painting or other surface treatments. Mill finish aluminum coil is widely used in construction and other industrial fields, especially in products such as structural parts, frames, and casings that require high strength and durability.
Common alloys of mill finish aluminum coil for construction are 1000 series pure aluminum (easy to process, corrosion-resistant, used for interior decoration), 3000 series aluminum-manganese alloy (rust-proof, moderate strength, suitable for outdoor curtain walls), 5000 series aluminum-magnesium alloy (high strength, marine corrosion resistance, used for coastal buildings), 6000 series aluminum-magnesium-silicon alloy (can be heat-treated and strengthened, used for door and window profiles), select according to the scene.
Thickness specifications: usually between 0.3mm and 3.0mm, common thicknesses are 0.3mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, etc. According to actual needs, thicker aluminum coils can also be produced, such as 3003H24 aluminum coils for high-rise building curtain walls, with a thickness of up to 6-12mm.
Width specifications: generally between 800mm and 1200mm, but there are also products with a wider width range, which can reach about 2000mm. The specific width can be customized according to customer needs.
Advantages of mill finish aluminum coil for construction:
- Cost advantage:
No additional surface treatment process is required, which reduces the processing cost. In large-scale construction projects, it can effectively control costs and has a high cost performance.
- Quality advantages:
It has the characteristics of light weight, high strength, corrosion resistance, and easy processing. Its density is about 1/3 of iron or copper. After cold processing or heat treatment, the strength of the matrix can be strengthened. At the same time, a dense and firm protective film is easily formed on the surface of the aluminum coil, which can well protect the matrix.
- Environmental advantages:
Aluminum coils can be recycled and reused, which meets the requirements of the modern construction industry for environmentally friendly materials and is conducive to reducing resource waste and environmental pollution.
- Appearance advantages:
It presents a natural metal texture, has a simple and modern aesthetic, can bring a unique visual effect to the building, and this natural appearance can be integrated with various architectural styles, whether it is a modern minimalist style or a retro style building, it can show its unique charm.
Application scenarios of mill finish aluminum coil in construction:
- Building curtain wall:
It is one of the commonly used materials for building curtain walls, and can be used directly as a curtain wall panel to provide the building with a beautiful appearance and good protective performance. For example, the facades of some large commercial buildings are made of curtain walls made of mill finish aluminum coils. Under the sunlight, they present a natural metallic luster and are very modern.
- Roof covering:
It is used for roof covering materials, has good waterproof and weather resistance, and can effectively protect the interior of the building from erosion by natural factors such as rain and sunlight. For example, the roofs of some industrial plants use mill finish aluminum coils as covering materials, which can not only reduce the weight of the roof, but also extend the service life of the roof.
- Sunshade facilities:
It can be processed into sunshades, awnings and other sunshade facilities of various shapes and sizes to provide sunshade functions for buildings, reduce indoor temperatures, and save energy. In some residential buildings, sunshades made of mill finish aluminum coils can block direct sunlight and add a simple beauty to the building.
- Interior wall decoration:
It is also used in the interior wall decoration of buildings. It can be made into various shapes of interior wall decorative panels through bending, cutting and other processing methods to create a unique atmosphere for the interior space. For example, in the lobby or conference room of some hotels, the interior wall decorative panels made of mill finish aluminum coils can show a high-end and fashionable feeling.
- Stairs and platforms:
It can be used to make stair treads, handrails and working platforms, etc. It has good wear resistance and corrosion resistance, and can meet the use requirements and safety standards of the building.
