Close to the end of the year, this decoration season, is not many consumers in the purchase of frameless balcony window, have no way to start, do not know how to start it? The following small series will give you a brief introduction to the selection and purchase of frameless balcony windows, so that you can "be prepared to fight" when choosing and purchasing frameless balcony windows.
There is a saying in this industry: six points of material, three points of technology, and one point of after-sales service
1、 Let's talk about the material first. The main components of the frameless balcony window are: up and down rails; moving glass in the middle; and connecting and pulling their accessories
First of all, track: no matter whether your balcony window is linear or curved with angle, the track material should be aluminum magnesium alloy (industry standard). Magnesium is added to aluminum alloy to strengthen the hardness of profile, It has a certain ratio limit (some individual processors tell customers that the more magnesium content, the better is wrong; too little, the material will deform after a long time; too much, on the contrary, it is too brittle and easy to break). Now the materials are alloy metals, not the thicker the material, the key is to see the content ratio of each item of the window track material. How to identify the window track material? If the conditions permit, we still need to find the authoritative department for appraisal. But generally, the most effective way is to cut the window track material. The qualified aluminum magnesium alloy window track has a smooth and glossy cut. The cut surface will not be black and uneven, and there will be no big burr on the edge. The appearance of window track is sprayed with fluorocarbon dust-free (three spraying and three coating). Only by such surface treatment can the profile be more aging resistant, yellowing resistant and smooth. (if the common spraying thickness is not enough, it is easy to fall off, and there are small particles on the surface, and the handle is not good.)
Say again glass: the glass that has no frame balcony window uses is all toughened. The quality of toughened glass depends on which glass factory's original piece is selected before tempering. (this is very important, because it determines the quality of glass in the future. If it is glass produced by small companies or irregular manufacturers, there will be impurities in it, and the transparency is not good. A straight line may become a curve Next it depends on which toughened glass company tempered. Before glass tempering, the manufacturer should cut according to the size of the glass, and then grind the edge. It should be noted here: there are many kinds of glass edging: manual edging has been basically eliminated, but there are still small workshops using mechanical computer edge grinding, but there are two types of edge grinding. The size error of single edge grinding is large, while the probability of dimension error is reduced by double grinding. No frame balcony windows are not encrypted seal, now why add it? In the past, the size error of glass edge grinding was large, which led to the large gap in the middle of glass and poor sealing performance. What's more, the tempering technology of some companies fails to meet the requirements, and the tempered glass is not vertical. So now some companies that do no frame balcony windows will not recommend non encrypted seals to customers, because their materials and technology can not meet the requirements of non encrypted seals. Regular frameless balcony window manufacturers will require the tempering company to mark the trademark, the mark of the tempering company and CCC Mark on each piece of glass they supply, so as to provide customers with the search and inspection. Therefore, I would like to remind you that what the salesman promised to you before signing the bill should be compared one by one after the window is installed to protect their own rights and interests.
