推拉门起源于中国，经中国文化传至朝鲜、日本。具体时间无从考证，但可以从中国的一些古画上看到零散的推拉门，例如宋代的山水画，就有推拉门。图中的为宋《营造法式》中记载的格子门。

Sliding door originated in China, the Chinese culture spread to Korea, Japan. Specific time impossible, but can be seen from some of China's ancient paintings scattered sliding door, such as the song dynasty landscape painting, there is a sliding door. In the figure for the "building" in the song dynasty recorded in the grid.

"Full name" Hong Kong beauty of choice for the international building materials company, is a professional production of various types of high-grade titanium magnesium aluminum alloy sliding door, partition door, door, open the door, wardrobe, bathroom products such as a large company, at present, the company is committed to the development of a variety of practical, new, environmental protection performance of light metal building decoration materials, after more than ten years of development, now has a certain scale of production, design, development and sales ability, has certain well-knownness in domestic has preliminarily set up the brand image, and has major cities in the country to set up distribution points. The company has advanced production equipment, exquisite processing technology, has a group of far-sighted management leadership, innovation of science and technology backbone, professional design team, skilled production workers.

铝合金

铝合金铝合金是工业中应用广泛的一类有色金属结构材料，在航空、航天、汽车、机械制造、船舶及化学工业中已大量应用。随着近年来科学技术以及工业经济的飞速发展，对铝合金焊接结构件的需求日益增多，使铝合金的焊接性研究也随之深入。铝合金的广泛应用促进了铝合金焊接技术的发展，同时焊接技术的发展又拓展了铝合金的应用领域，因此铝合金的焊接技术正成为研究的热点之一。纯铝的密度小，大约是铁的 ，熔点低，铝是面心立方结构，故具有很高的塑性

，易于加工，可制成各种型材、板材，抗腐蚀性能好；但是纯铝的强度很低，退火状态 b 值约为，故不宜作结构材料。通过长期的生产实践和科学实验，人们逐渐以加入合金元素及运用热处理等方法来强化铝，这就得到了一系列的铝合金。 添加一定元素形成的合金在保持纯铝质轻等优点的同时还能具有较高的强度， 值分别可达 。这样使得其“比强度”（强度与比重的比值 ）胜过很多合金钢，成为理想的结构材料，广泛用于机械制造、运输机械、动力机械及航空工业等方面，飞机的机身、蒙皮、压气机等常以铝合金制造，以减轻自重。采用铝合金代替钢板材料的焊接，结构重量可减轻50%以上。

Bits: 70 ~ 90%), easy to machining, can be made into all kinds of profiles, plates, good corrosion resistance; But the strength of pure aluminium is very low, annealing state sigma b value is about 8 KGF/was, therefore, not as a structural material. Through the long-term production practice and scientific experiment, people gradually to add alloy elements and using the method of heat treatment to strengthen aluminum, it's got a series of aluminum alloy. Add some elements to form the alloy while maintaining the advantages of pure aluminum light can also has high strength, sigma b value can reach 24 ~ 60 KGF/was respectively. So that its "strength" (the ratio of intensity and the proportion of sigma b/rho) is better than a lot of alloy steel, become the ideal structural material, widely used in machinery manufacturing, transportation, machinery and aviation industry, the aircraft fuselage, skin, such as compressor with aluminum alloy manufacture, in order to reduce weight. The welding of aluminum alloy instead of steel material, the structure can reduce more than 50% in weight.
