The typhoon landed at the center of Fengyan mountain at the lowest pressure of 162km / s on May 22nd, which was equivalent to the maximum pressure of typhoon typhoon at the center of typhoon Taiyan (at the center of typhoon Taiyan at the height of 16km / s).
I don't want to see the event of serious losses caused by typhoon, as a service to the door and window industry Intelligent doors and windows Xiaobian will feel sympathy and heartache.
Every time a typhoon comes, it is not uncommon for windows to fall and break. It is a natural disaster and also related to the quality of doors and windows.
It is understood that the most damaged doors and windows in gale, heavy rain or typhoon are fake plastic steel doors and windows, and aluminum alloy doors and windows with insufficient thickness. Therefore, consumers are reminded not to buy these problem doors and windows for safety!
The reason why doors and windows fall or break when typhoon blows:
As we all know, whether the aluminum alloy doors and windows can resist the super typhoon and rainstorm mainly depends on the wind pressure resistance and sealing performance of the aluminum alloy doors and windows. The reason why the doors and windows fall or break when the typhoon blows is mainly caused by the following quality details of doors and windows:
(1) the wind pressure resistance design value of aluminum alloy profile doors and windows is relatively small;
(2) the moment of inertia, strength and stiffness of aluminum alloy profile for doors and windows are small, and the deflection of profile under wind pressure is too large to reach the design wind pressure value;
(3) wrong design and selection of hardware;
The quality of hardware is not up to the national standard;
(5) the strength of glass design and selection is low;
(6) the anchoring point of aluminum alloy door and window frame is wrong;
(7) the design and selection of connectors are wrong, and the materials prone to chemical and electrochemical corrosion are not treated with anti-corrosion treatment, and the connection strength is low;
(8) the wall material of the door opening is poor, and the anchoring connection strength with the door frame is low.
The above are common door and window manufacturers, often ignore the quality details of doors and windows, and we do not understand the case, often choose poor quality doors and windows.
Several advantages of choosing brand broken bridge aluminum alloy doors and windows:
brand Broken bridge aluminum doors and windows Based on the principle of pressure balance, the structural drainage system is designed and installed, so the water tightness is excellent. and, Broken bridge aluminum doors and windows The frame material adopts hollow design, strong wind pressure deformation resistance and good anti vibration effect. At the same time, the advantages of brand bridge broken aluminum alloy doors and windows are as follows:
Rest assured in process design
When assembling brand bridge broken aluminum doors and windows, in addition to being firm and beautiful, it is also necessary to apply angle glue on the cross section of aluminum materials. After the completion of corner assembly, glue should be injected into the corner. The gap between the corner code and the profile should be filled with angle glue to make them a whole. That is to say, the connection is more firm, and the corner assembly position can be prevented from leaking. At the same time, the air tightness is improved Step by step.
There are only a small difference in the production of doors and windows, as well as the connection between Zhongting, milling accuracy and hardware assembly, etc. small workshops and brand doors and windows manufacturing technology are different.
Don't worry about profile
Brand broken bridge aluminum doors and windows in the material and quality are guaranteed, are in line with the requirements of national standards. According to the national building materials standards, Aluminum Alloy 6063 or 6061 is generally used for brand bridge broken aluminum door and window profiles, which have good stiffness, strength and corrosion resistance.
The wall thickness of the profile is not less than 1.4 mm specified in the national standard. The heat insulation strips are made of PA66 nylon specified in the national standard. Moreover, the tempered glass of the brand bridge breaking aluminum doors and windows generally has 3C certification mark.
Rest assured of hardware materials
Brand broken bridge aluminum doors and windows generally use regular hardware accessories, whether domestic hardware or imported hardware, as long as it is a regular hardware brand, the quality is no problem.
It is made of zinc alloy with good corrosion resistance. Good hardware to go through grinding, polishing, electroplating treatment, surface treatment more fine, acid and alkali resistance, corrosion resistance and smooth surface, easy to clean.
Safe installation and measurement
The measurement of door and window size is the most direct factor to determine the cost of doors and windows. Generally, brand bridge broken aluminum doors and windows have professional measurement team and supervision service.
For beams, columns, corner columns, protective frames, etc., such additional items are the most easy to increase the contract amount in a straight line. What are included in the quotation of each square meter, which need to be charged separately, and the amount of charges, etc., the manufacturers of brand broken bridge aluminum doors and windows will generally write all the details included in the pingmeter quotation on the voucher.
After sales service at ease
Brand bridge aluminum door and window merchants usually come to the door for accurate measurement, design drawings, accurate budget price, sign contract, pay deposit and start construction. After the construction is completed, there will be professional acceptance master for acceptance.
