[China Aluminum] With the continuous development of architectural forms and functional requirements, the requirements for windows and doors are getting higher and higher. In order to meet the requirements of architecture, the role of hardware system technology in the design of doors and windows needs to be re-thought. This looks very simple, but it is not. This requires meticulous planning, guidance, and investing a lot of energy and financial resources to achieve this design goal. Hardware system development and design should have a certain degree of flexibility and flexibility. In the design and development process, "building factors" and "human factors" should be fully considered. Its decorative, functional, safety, convenience and comfort should meet the requirements of architectural design.
For the ultimate goal of the development and design of aluminum alloy doors and windows system ---- a new form of doors and windows, only when the designer has a clear and complete design concept in mind, can produce a clear form of doors and windows. Therefore, in order to achieve this goal, designers must trace their problems back to earlier functional factors and find certain patterns in them. Only after understanding our goals and design guidelines can we develop systems. Therefore, the system development of doors and windows and the selection or development of door and window hardware are closely linked and complement each other.
More importantly, the wind pressure deformation, watertightness, airtightness, heat insulation, sound insulation, internal deformability, opening and closing, vertical load, and repeated opening and closing of doors and windows are all related to the hardware system. The hardware system is The pros and cons of the performance of the doors and windows play a decisive role, just as the door and window industry expert Prof. Li Zhiyi advocated that “hardware fittings are not supporting roles, but are the heart of doors and windowsâ€.
Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Natural Gas Mass Flow Meter, Natural Gas Mass Flowmeter, Natural Gas Coriolis Meter, Natural Gas Coriolis Mass Flow Meter, ATEX, IECEx & CE approved.
First, Sealand meter is certified by Zhejiang Institute of Metrology. To get such certificate, Sealand has to send all models to Zhejiang Institute of Metrology and all models are tested in their calibration lab. The lab is an ISO/IEC 17025:2005 standard lab approved by CNAS (China National Accreditation Service for Conformity Assessment). CNAS is a member of ILAC (International Laboratory Accreditation Cooperation).
Second, Sealand has its own calibration lab, equipped with METTLER TOLEDO scales with accuracy 0.014% and the device extended uncertainty is 0.05%. The lab is also approved by Zhejiang Institute of Metrology. This certificate will stay valid only for one year, Zhejiang Institute of Metrology will send their professor to Sealand every year to check and make sure that the lab is qualified still and then issue new certificate. During the production, each meter will be calibrated in this lab for 3 times, each time at 5 different flow rate.
Finally, Sealand also gets ISO, CE, SIL, ATEX & IECEx. Sealand is the only Chinese brand who gets ATEX & IECEx and it is from TUV SUD ( the most authoritative institute for ATEX).
