Construction products made of aluminum and aluminum alloy materials, usually processed into casting, forging and foil, plate, strip, pipe, rod, profile, and so on, and then by cold bending, sawing, drilling, assembly, painting and other processes.
Properties of pure aluminum strength low, their use is limited. But the addition of a small amount of a kind or several kinds of the alloy elements, such as magnesium, silicon, manganese, copper, zinc, iron, chromium, titanium, etc., can be obtained with different properties of aluminum alloy. Aluminum alloy and the cold working and heat treatment, further strengthening and hardening, the tensile strength is greatly improved.
Standard potential of the aluminum is -1.67 volts, chemical property is active, the role of oxygen and air formed oxide films with a solid layer of dense, so in the ordinary air and clean water, aluminum has a good corrosion resistance. But with the contact of steel or other metal materials will produce electrochemical corrosion, contact in a humid environment and concrete, cement mortar, lime and other basic materials will produce corrosion, contact with the wood, soil will produce corrosion. Therefore, the need for appropriate anti-corrosion treatment.
Method for producing aluminum alloy according to the production method, divided into casting aluminum alloy and wrought aluminum alloy. Building on the deformation of aluminum alloy, with rolling into plate, foil, strip, squeeze into a rod, tube or a variety of complex shape of the profiles. According to their performance, for different purposes, for antirust aluminium alloy, duralumin, super hard aluminum and special aluminum. Commonly used construction, industrial pure aluminum (L1) to (L1), antirust aluminum alloy LF2, LF21 and Forging Aluminum (LD2) deformation of aluminum alloy.
The biggest characteristics and use of aluminum and Aluminum Alloy, the first is the bulk density is about 1/3 of the steel, rather than the intensity (the ratio of ultimate strength and gravity) can reach or exceed the structural steel. Secondly, aluminum and Aluminum Alloy can be easily processed into various shapes, can adapt to all kinds of connection technology, which provides favorable conditions for building the section of the form of the most economical and reasonable structure. Therefore, the Aluminum Alloy can not only greatly reduce the weight of the building, saving materials, but also can reduce the component transport, installation work, speed up the construction progress. The earthquake zone and inaccessible mountainous and remote areas, the economic effect is more significant and Aluminum Alloy aluminum. Beautiful appearance, good corrosion resistance, high reflectivity of light and heat, the sound absorption performance is good, through the method of chemical and electrochemical can obtain different colors. So aluminum is widely used in industrial and civil buildings roof , walls, doors and windows, skeleton, interior and exterior trim panels, ceiling, ceiling, railing, arm, indoor furniture, store container and construction of the template.
The construction industry is one of the three main market of aluminum, the world around 20% of the total aluminum production capacity for the construction industry, the construction industry of some developed industrial countries, the amount of aluminum accounted for the fact that whether from the anti wind pressure, water tightness, air tightness performance or from the aspect of environmental protection, aluminum alloy windows have the superiority. This is because the plastic window with the same cross section compared to the moment of inertia of the aluminum alloy window is 3-4 times the plastic window; with the use of aluminum alloy profile in heat insulation break bridge, aluminium alloy window insulation, insulation performance is greatly improved, which is fit for the festival today strongly advocated the requirements.
Aluminum Alloy doors and windows hardware accessories is an important part of the performance and the quality of the play has an important influence on the windows function. Because of the development of modern technology, doors and windows hardware accessories (handle, handrail, hinge, slide, connectors, etc.) are more and more into the market. These products are all kinds of shapes and colors., the practicability and the appearance of a superb collection of beautiful things, and considerably. But due to the different parts of materials and surface decoration materials, their service life (mainly refers to the corrosion resistance, durability and strength) far, even the same color, even Aluminum Alloy window accessories handle is also similar to the gap of up to several times or even dozens of times. Aluminum Alloy hardware in addition to considering must have sufficient mechanical strength, but also pay attention to materials and Aluminum Alloy contact the use, can maintain the good corrosion resistance of aluminum alloy. Golden gate window hardware can achieve the design life, of aluminum alloy doors and windows in the use of process safety and durability is very important, only two binding to really play a window of aluminium alloy door is beautiful and generous, durable characteristics.
Door and window hardware fittings
Door and window hardware fittings
More than 30% of the total output of aluminum alloy doors and windows hardware corrosion characteristics and mechanism. In recent years, building aluminum products continue to be updated, color aluminum plate, aluminum composite, composite door and window frame, application of novel aluminum alloy template building products also increased year by year. China has in the industrial and civil construction application aluminum alloy production of roofing, walls, doors and windows, and gradually extended to inside and outside decoration, construction formwork, have achieved good results.
