Veneer 3003 Aluminum Curtain Wall For Commercial Building

Unique Texture Rich Color Long Lasting Aluminum Veneer Curtain Wall for Commercial Building

The aluminum veneer curtain wall is made of high-quality and high-strength aluminum alloy plates, the usual thickness is 1.5, 2.0, 2.5, 3.0MM, the model is 3003, and the state is H24. Its structure is mainly composed of panels, stiffeners and corners. The corner code can be directly formed by bending and punching the panel, or riveting the corner code on the small side of the panel. The stiffener is connected with the electric welding screw behind the board (the screw is directly welded on the back of the board) to make it a solid whole, which greatly enhances the strength and rigidity of the aluminum veneer curtain wall, and ensures the flatness in long-term use Degree, wind and earthquake resistance. If sound insulation is required, high-efficiency sound insulation and heat insulation materials can be installed inside the aluminum plate.

The surface of the aluminum curtain wall is generally treated with fluorocarbon spraying after pretreatment such as chromization. Polyvinylidene fluoride resin (KANAR500) for fluorocarbon paint topcoat and varnish. Generally divided into two coatings, three coatings or four coatings. Fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, has excellent resistance to cold and heat, can resist strong ultraviolet radiation, and can keep long-term without fading and chalking ,long lasting.

Features:
1. The aluminum curtain wall has good rigidity, light weight and high strength. The aluminum veneer curtain wall panel has good corrosion resistance, and the fluorocarbon paint can last for 25 years.
2. The aluminum curtain wall has good workmanship. The aluminum plate can be processed into various complex geometric shapes such as plane, arc and spherical surface by adopting the process of processing first and then painting.
3. The aluminum curtain wall is not easy to stain, easy to clean and maintain. The non-adhesiveness of the fluorine coating film makes it difficult for contaminants to adhere to the surface, and it has good cleanliness.
4. The installation of aluminum curtain wall is convenient and quick. The aluminum plate is formed in the factory, and the construction site does not need to be cut and simply fixed.
5. The aluminum curtain wall can be recycled and reused, which is good for environmental protection. Aluminum plates can be recycled 100%, and the recycling value is higher.

The aluminum curtain wall has unique texture, rich color and long lasting, and the appearance and shape can be diversified, and can be perfectly combined with glass curtain wall materials and stone curtain wall materials. Its perfect appearance and excellent quality make it popular with owners. Its light weight is only one-fifth of marble and one-third of glass curtain wall, which greatly reduces the load on the building structure and foundation, and the maintenance cost Low, high performance-price ratio.

The composite aluminum plate is made of two layers of 0.5mm pure aluminum plate inside and outside (0.2～0.25mm for indoor use). The middle layer is 3～4mm thick polyethylene (PE or polyvinyl chloride PVC) by rolling and heat bonding. The product is of certain specifications. Flat plate, such as 1220mm×2440mm. The fluorocarbon paint on the surface of the external composite aluminum plate is also completed by roller coating and rolling and heat bonding at one time. The thickness of the coating is generally about 20μm. The advantages of the composite aluminum plate are light weight, smooth surface, good flatness, and the same direction. There is no color difference and excellent on-site processability, which provides conditions for dealing with the external wall size changes caused by on-site construction errors, reducing the workshop processing cycle and shortening the installation period.

The panels of composite aluminum panels must be processed into wall panels during installation. First, the panels should be cut according to the size of the secondary design. When cutting the panels, the folding and placing dimensions should be considered. Generally, about 30mm is added on each side. According to the curtain wall According to the installation company, the yield rate of cutting boards is generally 60% to 70%. The cut composite board needs to be grooved on four sides, that is, cut the inner aluminum sheet and plastic layer of a certain width, leaving only the outer aluminum sheet of 0.5mm thickness, then fold the edges to a 90 degree angle, and then use aluminum profiles to make the same size The sub-frame is placed in the bent groove of the aluminum-plastic plate. The bottom surface of the sub-frame is bonded to the back of the aluminum-plastic plate with structural glue. The folded four sides are fixed to the outside of the sub-frame by riveting. There are reinforcing ribs to ensure the mechanical strength of the wallboard. The reinforcing ribs are aluminum materials and are bonded with structural adhesive. Some informal methods only fix the four corners of the composite board with angled aluminum. The reinforcing ribs are bonded with double-sided tape, which is firm Greatly discounted.

The aluminum alloy veneer is generally 2～4mm aluminum alloy plate. When making the wallboard, the sheet metal processing is first performed according to the requirements of the secondary design, and the edges are directly folded. The four corners are high-pressure welded into a tight groove shape. On the back, the fixing bolts with reinforcing ribs are reserved by means of electric welding and planting nails. After the sheet metal work is completed, the fluorocarbon paint is sprayed, usually with two coatings and three coatings, with a paint film thickness of 30-40μm. The aluminum alloy veneer is easy to process into arcs and multi-folded edges or acute angles, which can meet the needs of today's endlessly changing exterior wall decoration, and is rich in colors. Colors can be selected at will according to the design and the owner's requirements, which really broadens the architect our design space.
