How many calculations for a square meter of material?
Upstairs is also quite detailed, when we offer the general is for different types of curtain wall (different panels, keel in different forms to be separated), take a standard position of the surface, calculate the amount of various materials inside * Loss coefficient, and then divided by the area of this face, came out no square meters of the material.
Curtain wall material calculation points:
1. Panel: panel ratio of expansion area * utilization (general 1.03)
2. keel: linear density * per square meter length * utilization (generally 1.05 ~ 1.15, according to material specifications)
3. Attachment: use per square meter (weight or volume number) * Utilization rate (general 1.03)
4. Low-value consumables: 15 ~ 25 (yuan / m2, according to the type of curtain wall to consider)
5. Labor costs: market decisions
