Experts teach you how to distinguish plastic steel doors and windows

with the popularity of plastic steel materials, the first step in decorating second-hand houses is usually to purchase plastic steel doors and windows. After all, plastic steel doors and windows are airtight, light and cheap. But then comes another procurement problem - who should we choose in the face of the plastic steel door and window stores everywhere and their different prices

insiders specializing in doors and windows said that there are too many fake brand plastic steel doors and windows, and the authenticity can only be identified through purchase channels and product certificates. Manager Chen of Hanbang doors and windows frankly said that at least half of the so-called brand plastic steel doors and windows in the market are fake

however, there are various opinions about purchasing plastic steel doors and windows among owners of self decoration. Several plastic steel window brands and door and window processing enterprises in Hangzhou told reporters that in fact, many methods to identify the true and false are wrong

>& gt;& gt; Link: door and window purchase compulsory course bridge broken aluminum door and window surface view

flow legend method 1: the price of authentic plastic steel door and window is 180 yuan/square meter. If it is less than 165 yuan per square meter, then 100% is false

asked about the price of plastic steel doors and windows in a door and window processing shop on Wensan road. The boss said that the plastic steel doors and windows of ordinary glass were 160 yuan per square meter. If there were old doors and windows, they could also be recycled

at a plastic steel door and window processing point on Moganshan Road, the landlady said that if brand plastic steel doors and windows were used, 140 yuan per square meter would be the cheapest price in the urban area. The proprietress also took out samples of door and window profiles to show the reporter, which showed that their real products were not plastic products

expert point of view: not entirely right

I heard that this statement was circulating in the market, and the person in charge of a brand of plastic steel doors and windows laughed. He said that this is not the case. It may be that some small workshops spread such news in order to raise the price of fake profiles

the person in charge said that generally speaking, the cost of plastic steel doors and windows used by ordinary families is about 175 yuan per square meter, while the price received by tooling customers may be cheaper, and customers with large sales volume can naturally enjoy price concessions

Manager Chen of Hanbang doors and windows said that consumers may also buy authentic brand plastic steel doors and windows at about 165 yuan per square meter. After all, the cost of plastic steel doors and windows of different brands is different. Similarly, the purchase of plastic steel doors and windows with a price of more than 180 yuan per square meter is not necessarily authentic, and the price cannot be used as a standard to identify the advantages and disadvantages of plastic steel doors and windows

flow legend method 2: you take a piece of magnet to suck plastic steel. The more firmly you suck, the better, because there is a steel lining inside the plastic steel

actual phenomenon: when you walk into the small door and window workshop facing the street, you will find that there is no need to take a magnet at all, because the plastic steel doors and windows provided by the small workshop have no steel lining at all. When asked if it would be lined into the profile when making windows in the future, the shopkeeper said with a white eye that the steel components were mixed into the profile, where could he see it

expert point of view: not completely right

"some small stores may add a relatively thin steel lining in order to save costs, but also to fake lifelike, and the magnet can still absorb it!" An insider pointed out that the steel lining becomes thinner, and the surface seems to have little effect, but the fastness of the profile is much worse

it is understood that taking a famous brand profile that is sold more in the home decoration market as an example, according to the standard requirements, the thickness of the steel lining inside the plastic steel profile should be no less than 1.5mm, while the steel lining provided by the general small stores is only 0.6-0.8mm, with a thickness difference of nearly half, and the cost is virtually reduced by half

steel lining is mainly used to increase the firmness of plastic steel profiles. Using steel lining whose thickness does not meet the standard, the price can indeed be cheaper, but it is the consumers who suffer in the end

flow legend method 3: white green plastic steel material is good plastic steel, and white gray plastic steel is of poor quality

actual phenomenon: this statement is the most widely circulated method on the Internet to distinguish between true and false plastic steel profiles. It is said that as long as we grasp this principle, we will be able to buy real high-quality plastic steel profiles. However, like the leftover materials of the so-called best quality profiles provided by some roadside stores, ordinary consumers can't find out what color they can see except white even after looking at them for a long time. It is estimated that if most consumers do not compare the true and false plastic steel doors and windows, it is difficult to distinguish the quality of profiles by color alone

experts say: This is right

insiders say that there are many kana brand plastic steel products on the market now, and the color is generally white and gray, but it is difficult to find this without comparing with famous brand plastic steel windows

high grade plastic steel profiles should have a bright and clean surface and blue in white from the appearance. Such profiles have good anti-aging performance and will not age, change color and deform in the outdoor wind and sun for 30 to 50 years; The medium and low-grade profiles are white and yellowish. This color has poor sunscreen ability. After a few years of use, it will become more and more yellow until aging, deformation and embrittlement. The reason is that the profile formula contains too much calcium, which is another way for small workshops to reduce costs. Plastic steel doors and windows with excessive calcium carbonate are often unstable and affect human health

popular saying 4: insulating glass is made by clamping two pieces of ordinary glass together and extracting the air between them

actual phenomenon: this statement is spread in the Internet and real life, and even netizens wrote this in the decoration diary as experience to others. Several plastic steel processing sites in different areas of Hangzhou city have similar explanations for insulating glass: the glass of a door and window is sandwiched by two pieces of glass, and there is no air in the middle, so it is called insulating glass. According to their quotation, plastic steel windows made of insulating glass are not much more expensive than those made of ordinary glass

experts say: no

Zhang Bin is an engineer. His Hangzhou Hanks sound insulation technology engineering company uses plastic steel windows more. According to his explanation, insulating glass, vacuum glass and double-layer glass are completely different concepts

insulating glass does not empty the air between the two glasses, but cleans and dries the air between the two layers of glass to keep the air free of impurities. This kind of glass can play a certain role in heat preservation and sound insulation, and the price is more expensive than ordinary glass. Generally, there are few enough technologies in processing sites to deal with insulating glass in this way, so small workshops usually only make double-layer glass

vacuum glass is the one in which the air between the two glasses is completely pumped out. Some will add inert gases such as nitrogen. This kind of glass has high sound insulation and heat preservation performance, but the cost is also high. This kind of glass is rarely used in general home decoration
