1. Aluminum veneer: According to the size shown in the figure, the folding edge of the aluminum plate is not included in the 25 range. (Statistics of arc surface and formed aluminum plate)

2. Aluminum profile: Calculate the length of various specifications of aluminum multiplied by the linear density, and calculate the weight in kilograms.

3. Steel: first calculate the specification length, and then convert it into kilograms.

4. Embedded parts and angle steel bracket: Calculate the number of blocks according to the specifications, and then calculate their composition.

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

6. Sealant: first calculate the length of the joints of different sealants according to the diagram, and then calculate them into several numbers (usually the packaging of 500ml sealant is made into 3 meters long and 16mm sealant, and the packaging of 592ml sealant is made Into 16mm wide) 3.5 meters of sealant).

Or as follows:

Seam width (sisters) * seam thickness (sisters) (thickness is calculated as 10 sisters or half of the width) * seam length (m) / volume of each glue (ml) = glue quantity.

7. Other information: working days, including foam sticks, paper, rubber pads, cutting pads, electrodes, anti-rust paint, etc.

According to calculation, the price is 5~10 yuan/m2 at the restoration price.

Second, surface treatment

1. Fluorocarbon spraying: calculate the number of square meters according to the sprayed area;

2. Powder spraying: calculate the square meters according to the sprayed area;

3. Anti-rust paint: calculated according to steel composition;

4. Hot-dip galvanizing: calculated based on steel composition;

5. Fire-resistant coating (paint): calculated based on steel composition or the area of building open space;

6. Waterproof coating: calculation and construction of opening area;
