When purchasing doors and windows, where will you focus? Laymen usually pay attention to whether the color of doors and windows is novel and fashionable, and pay attention to the so-called "eye-closing edge"; Insiders will focus on the profiles, crafts and structures of doors and windows, especially hardware accessories. Why? Because hardware accessories are the heart of doors and windows, the heart (hardware) is not good. The so-called strong body (high quality) is just a mirror flower.
Generally speaking, judging the quality of a door and window usually depends on four aspects:
1. High quality and selection strength of profiles.
2. Whether the design process is scientific and reasonable.
3. Process technology in the manufacturing process.
4. The quality of hardware accessories is good or bad.
We can see that the quality problem of hardware accessories is often decisive to the importance of doors and windows! Hardware accessories are used as a bridge to communicate doors and windows parts. If the hardware accessories of a door and window are not good, then the door and window are not durable.
What does the hardware of doors and windows contain? The "five" in door and window hardware is a virtual numeral, not a quantifier, which refers to the general designation of various metal and non-metal fittings installed on the doors and windows of the building. They play an auxiliary role when the doors and windows are opened and closed.
Hinge, key to the life of doors and windows
Hinge is an important part to ensure that doors and windows can rotate and load. The quality of hinge is very important! A good hinge can ensure easy opening and no noise. In addition, the service life of hinge is also very important. If the quality is not good, once it encounters extreme weather such as Typhoon and rainstorm, there will be risks such as doors and windows crash.
Dagger, connecting window frame
Dagger link-type movable link that can connect the window fan surface and the window frame surface, and enable the window to open and close activities. If the casement window households in the big open encounter the bad weather of storm and rainstorm, dagger can also make casement window stand firm!
Pulley and track, key to protect doors and windows
Generally speaking, good quality pulley bearings are made of stainless steel. The bearings are tightly installed, and they feel soft and have no noise when sliding. Even some pulleys can also adjust the height, in this way, the distance between the door and the track can be made up, and finally the door and the track are connected more closely.
The track is a sliding and translating track of doors and windows. The existence of the track can facilitate the opening and closing of doors and windows, prevent the abrasion of the edges of doors and windows, and protect the doors and windows.
Handle, affecting the decoration style
Handle is undoubtedly the part that we have the most contact with doors and windows in daily life. Doors and windows handle can be divided into three categories: multi-point lock handle, single-point lock handle, and linkage handle. Whether the surface of the handle is smooth, whether there are burrs, whether there is a sense of quality and whether the surface of the coating is even; Whether the appearance of the handle is fashionable or elegant will directly affect the style of home decoration.
Lock point/lock seat, door and window safety core
Lock point and lock seat can play the role of closing and fixing doors and windows, and is the main accessory to ensure good anti-theft of doors and windows. Nowadays, there are two types of locks and single locks on the market for consumers to choose from. Simply speaking, each lock point is like a latch. Multiple Lock points are equivalent to more than 2 latches, and a single lock point is equivalent to a latch, so multiple Lock points are much stronger than single lock points, the price is also more expensive. In addition, it depends on the material of lock seat and lock point. The material of robber with poor material is broken after being broken twice, and its anti-theft ability is relatively weak.
How to choose the hardware of aluminum alloy doors and windows?
First of all, the wind pressure resistance, air tightness and stability required by doors and windows should be considered. When there is a requirement for wind pressure resistance, the number and layout scheme of locking points should be determined according to the local standard value of wind pressure and the height of the floor, to ensure the required wind pressure resistance, air tightness and stability requirements of doors and windows; Ensure safety: At the same time, considering the factors determined by the width and weight of the door, Casement, select window hinge (hinge), dagger, load-bearing grade, specification and size of load-bearing parts such as pulleys.
What is the impact of load on hardware selection?
Load requirements for hardware accessories of doors and windows: when hardware is selected, the three functions of doors and windows (wind pressure resistance, water tightness, air tightness) and performance requirements of heat preservation, heat insulation, sound insulation, etc. must be ensured first.
In 2012, the Ministry of Housing and Urban-Rural Development re-promulgated GB50009-2012 "load code for building structures", which has great impact on temperature, variable load, accidental load, various parameters such as permanent load and wind load height variation coefficient have been added and adjusted, and the contents and methods of wind vibration calculation have been greatly improved and perfected.
Door and window hardware affects door and window performance and window life
There is also fierce market competition in the building doors and windows industry. One of the important ways to get rid of single price competition and create a benign market environment is to continuously enrich product functions and expand product profit space with technological advantages. The important link that can enrich the functions of door and window products is hardware accessories.
The quality of hardware also affects the service life of doors and windows. Good hardware should look thick, and the surface gloss is good, the protective layer is dense, and there is no scratch phenomenon. The most important thing is that it feels warm and smooth, and the operation should be flexible without noise.
Today's doors and windows, high quality door and window system providers, with the spirit of craftsman who strives for perfection, rigorous, meticulous and scientific processing technology, refined and modern production process, advanced Enterprise management concept and humanized service concept have been recognized by consumers at home and abroad.
In order to cope with the increasingly fierce competition in the future, it has been compared with German ROTO and German Dr. Han. Hahn, also known as "big chicken hinge", HOPPE in Germany, gitigny in Italy (GHIDINI) and other internationally renowned hardware enterprises have reached strategic cooperative relations to achieve win-win cooperation.
Keep pace with the times and forge ahead. In the future, doors and windows will continue to improve product innovation and enterprise brand competitiveness, better provide consumers with high quality products, let quality enter life and enjoy high quality in life.
