The application of curtain wall aluminum veneer in the field of construction engineering has good rigidity, non-combustibility, high fire rating, light weight and high strength; convenient cleaning and maintenance; convenient and quick installation and construction. It has been formed by the manufacturer and does not require additional cutting during construction. It needs to be easily fixed; it can be recycled and reused and is environmentally friendly.

So what are the calculation methods for curtain wall aluminum veneer?

1. Aluminum veneer: The size designed according to the drawing is calculated in square meters, and the folded edge of the aluminum plate is not calculated within 25. (Single statistics of curved and special-shaped aluminum plates)

2. Aluminum profile: calculate the length of various aluminum profiles according to specifications and multiply the linear density, and calculate the weight in kilograms.

3. Steel: first calculate the length according to specifications, and then calculate the weight according to kilograms.

4. Embedded parts and angle steel support: calculate the number of blocks according to the specifications, and then calculate the weight.

5. Thermal insulation rock wool: calculated in cubic meters according to the design drawings.

6. Sealant: first calculate the length of different glue seams according to the design drawings, and then convert them into counts to calculate (usually packing 500ml sealant can make 16mm wide glue seam 3 meters, packaging 592ml sealant can make 16mm wide 3.5 meters glue seam). Or calculate according to the following method: glue seam width * glue seam thickness (thickness is calculated as 10 or half of the width) * glue seam length/volume of each glue = quantity of glue.

7. Other materials: including foam sticks, masking paper, rubber pads, cut-off pads, welding rods, anti-rust paint, etc., calculated by one item, reported 5-10 yuan/m2 based on the history value.

Surface treatment

1. Fluorocarbon spraying: calculated according to the spraying area;

2. Powder spraying: calculated according to the powder spraying area;

3. Anti-rust paint: calculated according to the weight of steel;

4. Hot-dip galvanizing: calculated according to the weight of steel;

5. Fire-resistant paint (paint): Calculated according to the weight of steel or construction area;

6. Waterproof coating: calculated according to the construction area
