Aluminum alloy doors and windows of the specific aspects of how the calculation
The first choice of each window window used to calculate the weight of the aluminum! If the aluminum marked 6 kg per square so the weight of aluminum left to the unit price is 6KG * per kilogram of price = aluminum prices used in the same way to calculate the price of glass
And then add the price of accessories coupled with the production of installation costs and gadgets! Plus your profits on the line if there is tax to add taxes!
Each type of profile has its own calculation formula, the calculation formula is summed up in the actual work and calculated, and now the profile model too much, each area of ??the profile is not the same, you can combine the profile table settlement I do not know which area you are in. I give you a very common calculation of the 70 formula, but this is not very absolute, and sometimes this type of material in the decline in the difference (the glide of the slide height Not the same), basically produced by this formula: a: no windows on the beam
1: Border = height of the window
2: up and down = window width -2 cm
3: hook light Kai = border -5.2 cm
4; up and down = up and down ÷ 2 + 0.5 cm (see details of the size of the three fans)
5: glass high = check light Kai -9.3 cm
6: glass width = upper and lower -6 cm (three fans in the middle of the big fan-7 cm)
7: yarn fan height = border -5 cm
8: yarn fan width = up and down +1 cm
Two: the window with the beam
1: Border = height of the window
2: Upper. Medium. Lower = width of window -2 cm
3: hook light Kai = cross the number of -1.2 cm
4: up and down = upper and lower ÷ 2 + 0.5
5: Board. Neutral = Border - Scribe Number 7 cm
6: hanging wire horizontal length = diameter -0.6 cm
7: Closed thread vertical = neutral. Board-1 cm (button cutting angle)
8: glass height = scribing number -10.5 cm (also = hook light -9.3 cm)
9: Glass wide as above
10: yarn fan height = scribing number -0.5 cm
11: yarn fan wide on the same
Three: three fan of the exception size (non-standard material to rely on their own to the amount and calculation)
1: three fans of the small fan up and down = (down +9) ÷ 4-1.8 cm
2: three fans of the big fan up and down = (down +9) ÷ 2
3: small fan of the glass above the same
4: large fan of the glass height, wide = up and down -7 cm
