  • 2020 New Version of China National Standards for
    Feb 02 , 2021

    The latest version of the national standard GB/T8478-2020 for "Aluminum Alloy Doors and Windows" was released on March 31, 2020, and has been officially implemented on February 1, 2021. The new 2020 standard is to replace the previous GB/T8478-2008 standard. Compared with the 2008 version, the 2020 version has been improved to a greater extent in the scope of application, classification terms, basic performance requirements, requirements for aluminum alloy materials, detailed requirements for door and window construction, door and window processing accuracy, repeated opening and closing durability tests, product identification and so on. Door and window classification terms The first change of the new national standard is in the terminology of the classification of doors and windows. The classification principle of doors and windows of the new national standard has been revised from the original "function" to "performance". The "shading type" has been changed to "heat insulation type" basing on which two new types "heat insulation type" and "fire resistance type" are added. This change has brought great convenience to consumers and producers. From the type and name of doors and windows, the main performance and characteristics of the doors and windows can be clearly understood. Basic performance requirements for doors and windows With the continuous development of the industry and the continuous improvement of technology, people's requirements for the quality of life are also constantly getting higher. As an indispensable part of a livable environment, the performance of doors and windows are also advancing with the times. The basic performance of doors and windows is the key standard for testing the quality of doors and windows, and the new national standard puts forward higher requirements for basic performance. Watertight performance: The watertight performance value ΔP of the outer door shall not be less than 150Pa, and ΔP of the outer window shall not be less than 250Pa. Airtight performance: For exterior doors with airtight performance requirements, the air permeability per unit opening length q1 should not exceed 2.5m3/(m·h), and the air permeability per unit area q2 should not exceed 7.5m3/(m2·h); For exterior windows with tight performance requirements, q1 should not exceed 1.5m3/(m·h), and q2 should not exceed 4.5m3/(m2·h). Airborne sound insulation performance: The sound insulation performance value of sound insulation doors and windows shall not be less than 35dB. Heat preservation performance: The heat transfer coefficient K of thermal insulation doors and windows should be less than 2.5W/(m2·K). Thermal insulation performance: The solar heat gain coefficient SHGC of insulated doors and windows should not be greater than 0.44. In addition, the new national standard also provides corresponding regulations on fire resistance, lighting performance, sand and dust resistance, wind resistance and debris impact resistance, which more compre...

  • Aluminum Material Specs Used by Shuangheng
    Jan 14 , 2021

    A-grade Aluminum Material Aluminium is an economy metal material and it is widely used in all industries. It has high-strength and high durability. It is also environment friendly and can be applied to different high-performance coatings. Great aluminum material is the most important considerations no matter for building or for industrial use. Choosing the appropriate material will ensure the extrusions and accuracy of parameters especially thickness. Shuangheng is using A-grade aluminium material to produce profiles which contributes to customers' business success. Aluminum Material Specs

  • Advantages of aluminium profile table
    Dec 21 , 2020

    Aluminum profile table for the aluminum profile as raw materials of the work table, then introduce the aluminum profile, that is, the aluminum bar through hot melt, kneading, and then get different cross-section shape of the aluminum data.The production process of aluminum profile mainly includes three processes: casting, kneading and coloring.Meanwhile, the coloring mainly includes oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer and other processes.Of course, the working table is very simple to understand. It is made of high-quality cold-bonded boards and made of fine workmanship. The firm and stable working table structure can make the working table bear 1000kg.A variety of work desktop selection, can be used in cooperation with the requirements. Advantages of aluminium profile table: 1. First compare aluminum and steel.In the manufacturing sector, steel has been a much anticipated source of information because it is cheap and widely used.But steel also has many defects.Processing costs both time and labor.Welding is a costly process, the primary reason for which is the training of welders.In addition, processed data is often not a perfect match, so reprocessing can be costly.When reprocessing is carried out, even the reinput of the machine is required. 2. Then talk about the aluminum table -- the assembly is simple and high strength, can make the work table bear extra weight, according to the bearing is different divided into light, medium and heavy work table;It is convenient to transfer, disassemble and assemble, green and environmentally friendly finished products. The working table can be equipped with hanging board, electrical board, lamp roof, pulley bar, shed board and other table components, which can satisfy all kinds of work station needs. Aluminium is in many ways more stable and economical than steel.But not all aluminum is created equal.When selecting a supplier, you should pay more attention to the long experience accumulated by the data provider and the reference items related to this data.
