Aluminum Plank Good Strength, Low Cost, Long Life Oct 30, 2017

Aluminum Plank, as the name implies, refers to the use of aluminum or aluminum alloy material made of plate type material. Or it is made by the process of heating, rolling and straightening, or solid-solution aging heat, made of Aluminum Plank-type products.

The Aluminum Plank used in the building includes a single-layer Aluminum Plank, composite Aluminum Plank and other materials, usually refers to a single layer of aluminum (also known as single Aluminum Plank or pure Aluminum Plank), more used in building decoration engineering, in recent years in the Aluminum Plank curtain wall single layer of Aluminum Plank used more see. Aluminum curtain wall is also a form of curtain wall, simply to use Aluminum Plank instead of glass curtain wall, aluminum curtain wall is used for wall cover and no light wall. Aluminum curtain wall in foreign countries has been using single layer Aluminum Plank. Single-layer Aluminum Plank general use of pure aluminum. Aluminum Plank thickness of 3mm, in order to strengthen the Aluminum Plank surface strength, in the back of the Aluminum Plank, the reinforcement must be installed (now some manufacturers are uneasy), reinforced with thick aluminum strips, first with a flash welder to weld the nut on the back of the Aluminum Plank and then make the reinforced bar of the aluminum drill hole sleeve into the screws, fixed with screws. In order to reduce the weight of Aluminum Plank, increase the strength of Aluminum Plank, we use aluminum alloy plate, often choose 21st rust-proof Aluminum code LF21 pressure into Aluminum Plank for curtain wall aluminum. The thickness of aluminum sheet is reduced from 3mm to 2.5mm, the strength of the alloy is higher than the pure Aluminum Plank. Reinforced with LF21 aluminum strip, the width of the aluminum strip according to the Aluminum Plank surface, general thickness 2-2.5mm, Wide 10-25mm. Aluminum Plank curtain wall of Aluminum Plank back why to strengthen the tendons, is in the external positive and negative pressure situation, the Aluminum Plank will not sag, two will not bulge, so as to avoid the Aluminum Plank wall repeatedly vibration and vibration sound. If the need for sound insulation, can be inside the Aluminum Plank, placing rock wool, slag cotton or foaming treatment. The first Aluminum Plank curtain wall Manufacturers in China, Chongqing Southwest Aluminum deep-processing Plant, the factory for military manufacturers, the production of Aluminum Plank width can reach 2.8 meters. Curtain wall Aluminum surface treatment, can be divided into two methods, one is anodic oxidation, the other is electrostatic spraying. Anodic oxidation of the oxide film in general 12μ above, the color only bronze and white two kinds, the color monotonous, more serious disadvantage is each piece of Aluminum Plank surface color varies, many pieces of wall panels together to form a curtain wall overall effect is very ugly. This shortcoming can be said to be impossible to eliminate, not the production technology, but because the Aluminum Plank is not by a batch number, chemical composition, there are small differences, coupled with the oxidation of the cell current density and other factors can not be exactly the same, so the color of the oxidation of the number of differences, the single picture may not be obvious, if all lined up is very obvious. therefore Aluminum Plank curtain wall Aluminum Plank surface treatment, must not use anodic oxidation.

Because the single layer Aluminum Plank is more easy to bend and shape than honeycomb Aluminum Plank, and can better adapt to the changing demand of the endless architectural exterior wall decoration, it is generally believed that the Single-layer aluminum sheet is the best material for aluminum curtain wall. Can be a variety of color spraying surface, good strength, low cost, long life, if not directly contact with steel, Aluminum Plank hanging on the wall, 50 will not fall off and corrosion, (before liberation in Tianjin, the roof of the Aluminum Plank is still intact). Life expectancy may be longer and the building life is matched.

Single-layer aluminum curtain wall, is made of pure aluminum 3mm or LF21 2.5mm aluminum sheet veneer wall panels, single-layer Aluminum Plank is due to the development of the electric bolt welding technology, electric bolt welding to achieve a single layer of aluminum veneer on the back of the reinforcement of welded reinforcement, without damaging the Aluminum Plank finishes, single layer Aluminum Plank easy bending processing into complex shapes, High strength and long life (up to 50 years), so it is the appearance of Aluminum Plank curtain wall in the form of processing and installation of a lot of structural form.

Single-layer integral stamping aluminum sheet "is made of single layer Aluminum Plank, which can be regarded as a special case of single layer Aluminum Plank in order to meet the exterior shape of the building.
