How many types of metal aluminum plates are there? Where is it used?

For interior designers, mentioning metal plates is almost equivalent to aluminum plates and stainless steel. With more and more stringent fire regulations and the gradual maturity and realism of metal material production technology, it is only a matter of time before non-combustible Class A metal materials replace flammable Class B materials.

Today, I will discuss the related content of aluminum plate with you, mainly to solve the following problems:

1. What does the "aluminum plate" often used by designers mean?

2. What are the characteristics of aluminum veneer?

3. What are the treatment methods for aluminum veneer?

01. What does "aluminum plate" mean? Where can it be used?

1. Application of metal materials

Before explaining, let us first see how many metal materials can replace traditional materials.

△Instead of white latex paint finish

Replace hard bag/leather engraved finish

In addition to the changes in the materials used in the design case, it can also be seen from the increasingly stringent fire inspection that metal will inevitably replace Class B materials. The future interior design industry (especially the mold industry) will use aluminum plate materials to follow suit. The current stone and wood finishes are of the same order of magnitude.

2. What exactly is the aluminum plate in the designer's mouth?

△The name of the aluminum plate in the designer's mouth

Recognizing these metal plates is as difficult as distinguishing wood, large core, multi-layer, plywood, plywood, vanilla board, Ouzong board, particle board, particle board, Aosong board...

What should I do now? Don't worry, everyone has first established a comprehensive understanding of aluminum plates. From the perspective of classification logic, aluminum panels used in the architectural decoration industry are mainly divided into two types: "aluminum single panels" and "composite panels".

One, aluminum veneer

△Aluminum Veneer

Aluminum veneer refers to a new type of building decoration material that uses aluminum alloy sheet as the base material, is processed by CNC bending and other technologies after chromium treatment, and then processed by fluorocarbon or powder spraying technology. The wood grain transfer aluminum plates, punched aluminum plates, imitation stone aluminum plates, and mirror aluminum plates that we often say all belong to this type of aluminum plate.

b. Composite board

△Aluminum Plastic Panel

Aluminum composite panel is a general term, which mainly refers to the chemically treated coated aluminum panel (aluminum veneer) as a surface material, compounded on a suitable substrate, and finally made into an aluminum composite panel through various complicated processing methods. According to different composite substrates, aluminum composite panels have different material properties.

For example, ordinary aluminum-plastic panels are composite panels of plastic + aluminum veneer, which not only retains the characteristics of plastics, but also overcomes the disadvantages of metal materials to plastics.

△The indoor application of aluminum-plastic panels

Another common aluminum composite panel is honeycomb aluminum panel: it is a composite material composed of honeycomb metal + aluminum veneer. In addition to retaining the performance characteristics of the aluminum veneer, the honeycomb metal structure base layer also greatly compensates for the flexibility of the aluminum veneer. In larger and larger space occasions, in order to ensure the flatness of the veneer material, this material will be used.

2. Knowledge of aluminum veneer

After dividing aluminum panels into "aluminum single panels" and "composite panels", everyone should have a rough framework in mind. Next, let us focus on the knowledge of aluminum veneer materials that everyone must know.

1. The difference between aluminum veneer and stainless steel

The surface treatment of the stainless steel plate is directly on the pure stainless steel plate through electroplating, water plating, etc., wire drawing, sandblasting or etching, which is simple, rough and easy to remember. The processing method of aluminum veneer is more complicated.

△Graphic aluminumveneer

The structure of ordinary aluminum veneer is mainly composed of panels, stiffeners and corners. The surface is usually treated with chromium and then treated with fluorocarbon or powder spraying, usually divided into two coats, three coats or four coats. Aluminum veneer generally uses 24mm thick pure aluminum plate or high-quality aluminum alloy plate as the basic material for surface treatment. In China, 3.0mm thick aluminum alloy panels are usually used for exterior wall decoration.

△Aluminum veneermodel

It is mentioned in the actual combat guide: Fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, has excellent heat and cold resistance, and can resist strong ultraviolet rays. Keep the color unchanged, no chalking, and long service life. Therefore, these seemingly complicated treatment methods have also led to the use of aluminum panels instead of stainless steel as exterior curtain walls in large buildings.

2. Advantages of aluminum veneer

The fundamentalreason why aluminum veneers and stainless steel plates have become the two giants of interior decorative metal plates is that aluminum veneers have the following characteristics:

1. Light weight and high strength

The 3.0 mm thick aluminum plate weighs 8 kg per square and has a tensile strength of 100280N/m. (N = Newton, mechanical unit)

b. Good durability and corrosion resistance

Use pvdf fluorocarbon paint or powder spraying to ensure excellent weather resistance and corrosion resistance.

c. easy to process

By adopting the process of first processing and then painting, the aluminum plate can be processed into various geometric shapes, such as flat, curved and spherical, so as to meet the complex modeling requirements of buildings.

d. Uniform anti-coating and various colors

The advanced electrostatic spray removal technology makes the paint and the aluminum plate adhere evenly, has a variety of colors, has a large selection space, and meets the architectural requirements.

e. not easy to stain, easy to clean and maintain

The non-adhesion of the fluorine coating makes it difficult for contaminants to adhere to the surface, and has good self-cleaning performance.

f. installation and construction, convenient and quick

After the aluminum plate is processed in the factory in accordance with the order drawings, it is directly installed on-site, without on-site cutting and processing. Therefore, the construction efficiency is very high, especially when facing some polygonal and two-dimensional surface modeling, this function is more reflected.

G. Can be recycled and reused, good for environmental protection

Aluminum panels are different from decorative materials such as glass, stone, ceramics and aluminum-plastic panels. They can be recycled 100% and have a high residual value.

3. Disadvantages ofaluminum veneer

① The biggest disadvantage of aluminum veneer is that it is difficult to achieve a high degree of reduction effect in replacing the tactility of traditional materials.

② When aluminum veneer is used as a decorative material in a large area, it is difficult to ensure the flatness of the aluminum plate and it is easy to produce ripples. Therefore, when the flatness of the aluminum plate is required, it is not recommended to use the aluminum single plate, but the honeycomb aluminum plate is better.

△If the metal plate is too thin, the surface must be uneven

Of course, these defects will not be covered up. Because these aluminum veneers have these characteristics, they have a high position in the sheet metal industry and are widely used in indoor and outdoor environments.
