I. Material differences and price differences:60 series Broken Bridge aluminum material width is 6cm, 70 series Broken Bridge aluminum refers to the material width is 7cm, the difference between the two is one cm, that is, there is a difference of this one cm, there is a big difference between the installation environment and the price.
(1)60 series Broken Bridge aluminum is suitable for narrow window sill width, no heightening treatment on the table top, the size of a single window is generally small, and the width of the window is less than 1.2 m.
(2)70 series Broken Bridge aluminum is suitable for large window size or large floor-to-ceiling windows. 70 broken bridge aluminum is stronger, with better sealing and heat insulation.
The main materials are Zhongwang and Jianmei. The unit price of 60 series per square meter is 428 yuan; The unit price of 70 series per square meter is 580 yuan (excluding hardware car window shade fees) here, you should know that in addition to knowing the unit price of broken bridge aluminum for Series 60 and series 70, we need to determine the number of windows to calculate the total price.
It can be calculated according to the formula: total price = unit price of the material * number of windows in square meters * number of windows in hardware * number of windows in car window shade.
II. Differences in sealing structure:60 series Broken Bridge aluminum are generally three or six sealed, while 70 series Broken Bridge aluminum has reached ten sealed
III. Material wall thickness difference: the wall thickness of 60 series Broken Bridge aluminum is only 1.4mm (National Standard), while the wall thickness of 70 series Broken Bridge aluminum is 1.8mm. The wall thickness is the thickness of the material.
4. Glass difference:60 series Broken Bridge aluminum standard 5 15 5 hollow glass, 70 series Broken Bridge aluminum standard is 5 22 5 hollow glass, can be equipped triplex glass. "5" in the glass indicates that the glass is 5mm thick, and "15" and "22" indicate that the distance between the two glasses is 15 and 22mm, different glasses separated by aluminum spacing strip are also one of the conditions that directly affect the sound insulation,
V. Width difference of heat insulation strip:60 series Broken Bridge aluminum commonly used 2cm insulation strip, 70 series Broken Bridge aluminum commonly used 2.5cm insulation strip, insulation Strip width is better than narrow on insulation.
The above is the difference between 60 series and 70 series Broken Bridge aluminum and the price difference. If you want to spend the least money to make the most ideal doors and windows, please choose a regular manufacturer, which not only saves the intermediate link of the exhibition hall, but also can clearly see the whole processing process, so that you can use it at ease, look at it comfortably, after-sales peace of mind.
