Recently, I heard from a friend of the owner that I was almost cheated when I closed the balcony at home for bridge-cutoff aluminum alloy. The price that was originally negotiated has been planned. I asked another one casually, and found that the same materials and practices were much cheaper. As a result, I made a cheap one. Now I find that I have been cheated, and I am very regretful.
But in fact, in the door and window industry, the price of the same material may be different.
Today, I will analyze the price difference from the aspects of material cost and process cost.
Aluminum profile
The thickness of broken bridge aluminum profile ranges from 1.2mm to 1.8mm. According to the calculation of 6m profiles, each 1.2mm profile is 70 yuan cheaper than 1.8mm. However, a window of 1 square meter often requires a profile of about 6m.
Glass
First of all, the broken bridge hollow glass has non-tempered hollow, single-sided tempered hollow, and double-sided tempered hollow. For materials alone, non-tempered hollow is about 70 yuan per square meter, while double-sided tempered Hollow can reach more than 120 yuan per square meter.
Heat insulation strip
Ordinary PVC insulation strips are generally about 6000 to 7000 tons, while nylon 66 insulation strips are as high as 28000 yuan per ton, which is estimated to be 50 yuan per square meter.
Hardware
Take a set of hardware opened in it for example. The low price is less than 50 yuan in the market, while the good quality is 200~300 yuan, especially imported brands, it is as high as 400~500 yuan.
Silicon sealant
In the installation
broken bridge aluminum doors and windows in order to save money, some people use sealant for caulking for two or three yuan each, while others use structural adhesive on the outer wall to meet the quality requirements, each piece reaches more than 18 yuan. Take consumers as an example, do you want to use two or three pieces of glue to save money? Or use better quality structural adhesive for quality?
