Metal curtain wall is a new type of building curtain wall used for decoration. It is a kind of curtain wall form in which the glass in the glass curtain wall is replaced with a metal plate. However, due to the difference of the surface materials, there is a big difference between the two, so they should be considered separately in the design and construction process. Due to the excellent processing performance of the metal sheet, the variety of colors and the good safety, it can fully adapt to the design of various complex shapes, can add concave and convex lines at will, and can process various types of curved lines. Architects are favored by architects for their huge space to play, and they have developed by leaps and bounds.
Since the late 1970s, China’s aluminum alloy doors, windows, and curtain wall industries began to take off. The popularization and development of aluminum alloy glass curtain walls in architecture has grown from scratch, from imitation to self-development, and from undertaking the construction of small projects to contracting. Large-scale engineering projects, from the production of low-end and low-end products to the production of high-tech products, from the construction of low- and mid-rise building doors and windows to the construction of high-rise glass curtain walls, from only processing simple low-end profiles to extruded high-end profiles, from relying on imports to develop In foreign contracting projects, aluminum alloy doors and windows and glass curtain walls have developed rapidly. By the 1990s, the emergence of new building materials promoted the further development of building curtain walls. A new type of building curtain wall appeared one after another throughout the country, namely metal curtain walls. The so-called metal curtain wall refers to the building curtain wall whose panel material is sheet metal.
Aluminum composite panel
It is composed of a 2-5mm thick polyethylene or rigid polyethylene foamed board sandwiched between the inner and outer layers of 0.5mm thick aluminum plates. The surface of the board is coated with fluorocarbon resin coating to form a tough and stable film. , The adhesion and durability are very strong, the color is rich, and the back of the board is coated with polyester paint to prevent possible corrosion. Aluminum composite panel is a commonly used panel material in the early appearance of metal curtain walls.
Single layer aluminum plate
Using 2.5mm or 3mm thick aluminum alloy plate, the surface of the single-layer aluminum plate for the exterior curtain wall is the same as the front coating material of the aluminum composite plate, and the film layer has the same toughness, stability, adhesion and durability. Single-layer aluminum panels are another common panel material for metal curtain walls after aluminum composite panels, and they are used more and more.
Honeycomb aluminum plate
Fireproof board
It is a kind of metal plate (aluminum plate, stainless steel plate, color steel plate, titanium zinc plate, titanium plate, copper plate, etc.) as the panel, and a core material modified by halogen-free flame-retardant inorganic substance as the core layer. Fireproof sandwich panel. According to GB8624-2006, it is divided into two combustion performance levels A2 and B.
Metal sandwich fireproof board
It not only has the function of fire prevention, but also maintains the mechanical properties of the corresponding metal-plastic composite board. It can be used as exterior wall, interior wall decoration material and indoor ceiling for new buildings and refurbishment of old houses. It is especially suitable for some large-scale public buildings with high population density and high requirements for fire resistance, such as conference centers, exhibition halls, and gymnasiums. , Theater, etc.
Titanium-zinc-plastic-aluminum composite panel
It is a new type of high-grade aluminum-plastic board building material made of titanium-zinc alloy plate as the panel, 3003H26 (H24) aluminum plate as the back plate, and high-pressure low-density polyethylene (LDPE) as the core material. The characteristics of the board (metal texture, surface self-repairing function, long service life, good plasticity, etc.) are integrated with the advantages of flatness and high bending resistance of the composite board. It is a model of the combination of classical art and modern technology.
