Frameless balcony window industry has a saying like this; six points of material, three-point technology, plus one minute after-sales service. 'The combination of the above three can we get very satisfied with the product.
First, let's talk about materials.
The main components of the frameless balcony window are: the upper and lower track; the glass moving in the middle; plus the accessories to pull them.
Let's talk about the track: Whether your home's balcony windows are straight or angled arcs, their track material should be aluminum-magnesium alloy (industry standard). Magnesium is added to the aluminum alloy to strengthen the hardness of the profile. It is There is a certain ratio limit (some individual processing households say to customers that the higher the content of magnesium, the better it is wrong, too little, the material will be deformed after a long time; too much, but too brittle easy to break). Now all materials Is the metal, not the thicker the better, the key is to look at the material content of the window track ratio. How to identify the window rail material? If conditions permit, or find authority to identify. But generally the most effective is to look at the window track material cuts, the qualified aluminum-magnesium alloy window track its incision is very smooth gloss, the cut surface will not be black and will not appear uneven, there will not be a big edge glitch. The appearance of the window track is coated with fluorocarbon dust-free coating (three sprays and three coats). Only after such a surface treatment profile can it be more resistant to aging and yellowing and the surface is smooth. (Ordinary spray thickness is not easy to fall off, the surface has a small particle feel bad.)
Besides glass: the glass used for frameless balcony windows is all tempered. The quality division of tempered glass depends on which glass factory produced the original film before tempering. (This is critical because it determines the quality of the glass in the future. If it is a small company or an informal manufacturer The glass, which has impurities inside it, has poor transparency, and a straight line may become a curve!) Next it will be determined which tempered glass company is tempered. Before glass tempering, manufacturers should cut according to the glass size, and then edging. Here we must pay attention to: There are many types of glass edging in current windows: manual edging is basically obsolete but there are still small workshops in use. Now they are all edging with mechanical computers, but here they are squaring and double-edged. . Here, the size is large, the size error of a single edging is large, and the double edging reduces the probability of a dimensional error. Frameless balcony windows are all without seals. Why are they added now? In the past, the edging size error of the glass was large, resulting in large gaps in the middle of the glass and poor sealability. Then there are some companies that do not meet the requirements of tempering technology, tempered glass is not vertical. So now some companies that make frameless balcony windows will not recommend to customers without seals, because their materials and technology can not meet the requirements of unsealed. The regular frameless window and balcony manufacturers will require the tempering company to mark the trademark, the steel company's mark, and the ccc mark on each piece of glass that they supply for customers to look for. So here to remind you: salesman to promise you before the signing, after the window is installed, you should compare them and safeguard your own rights and interests.
Next say accessories:
In the industry standard of frameless balcony windows, it is stipulated that the up and down plastic materials used for frameless balcony windows must be reinforced nylon or nylon with glass fiber added. Metal parts used for frameless balcony windows must be rustless. Otherwise, it will not meet the requirements for safety and service life. (And nowadays some of the accessories used to make frameless balconies on the market are ordinary plastic parts. The metal parts are rusted. These can be seen on the sample windows they provide.) Because the frameless balcony windows are On the suspended type, the main load-bearing capacity is on the upper track. After a long time, the accessories are worn out, resulting in inflexible windows opening and increasing the maintenance rate of the product. There is also a last part we should pay attention to: the connection of glass and profiles with steel gas rivets. The rivet is riveted with a pneumatic gun. The role of the pneumatic rivet is as follows: First, the safety of the frameless balcony window will never fall off, and the pneumatic rivet adopts the anti-dropping technology. Once it is riveted, there is no need to loosen and fall off. The second is that the frameless balcony window is beautiful and never rust. The material of the pneumatic rivet is stainless steel. The riveting performance is smooth and there is no feeling of scratching. The third is the stability of the frameless balcony window, because the air pressure riveter is Set at a pressure value, whether you are on a rivet or a thousand or more, it is the same pressure, so as to ensure its safety. Some of the non-framed balcony windows producers do not have pneumatic rivets and equipment. They use hand-pulled rivets. They also use aluminum rivets, while others use rivets with high iron content. However, no matter what kind of steel they use, they cannot meet the requirements for the quality and safety of steel rivets. So please note that the difference between these unframed balcony window fittings when choosing friends.
