Aluminum Trim Coil Stock

1. Aluminum Tim Coil Stock Abstract ： The aluminum trim coil is often used in the roofing system, which is a low maintenance and durable trim solution. Rich colors and fin grain bring strong decoration and long service life. What are its specifications? Learn more. Aluminum Trim Coil Thickness The aluminum trim coil thickness is mainly related to the coating equipment. The usual coating equipment can process color coated aluminum coil with a thickness of 0.3-1.2 mm, which is also a common specification for the most application. The thickness control of textured aluminum trim coil consists of three parts: substrate thickness, coating paint thickness, and protective film thickness. Generally, the thickness of the single-coated paint film is around 15um, and the thickness of the double-coated paint film is 25um. The thickness of the back paint film of the aluminum coil is around 5-8um. The thickness of the protective film is usually 0.05 mm. PE protective film is generally used. What we should pay attention to is that the PVDF coated aluminum coil is double-coated while the polyester coated aluminum coil is divided into single coating and double coating. The thickness tolerance of aluminum siding trim coil is ± 30um-50um. Haomei Aluminlum supplies color-coated aluminum coils of various thicknesses. And the non-standard sizes and widths can be customized. The colors can also be customized according to the RAL color card or other standard color card numbers, and can also be processed according to samples. Service Life of Color Coated Aluminum Coil The color coated aluminum col is often used for the roofing system of buildings. Its weather resistance and service life attracts many customer’s attention. There are two kinds of coating aluminum coils: PVDF and Polyester aluminum coil. Lets have a look together.

2. PVDF coated aluminum coil This is a durable colored aluminum coil with a long service life, generally up to 20-30 years. At present, our common large steel structures such as stadiums, railway station waiting rooms, theaters use it as the roofing material. Considering the long service life, the Fluorocarbon color coated aluminum coil is a primary choice. Polyester coated aluminum coil Its service life is about 10-15 years, which is usually used for the enterprise workshops and walls. It is an economic choice for those building which is not required to have a very long service life. It is of good adhesion and medium chemical resistance. As for which one to choose, we need to consider many factors such as the specific use, application environments and pressure endurance. For those regions where there is heavy rain or snow,we should choose a thicker and stronger coated aluminum coil. Delivery Date of Aluminum Gutter Coil The aluminum gutter coil has too many color to stock , therefore it requires certain processing period. The colors can be customized according to the RAL color card or other standard color card numbers, and can also be processed according to samples. The customer needs to consider the processing period when ordering, and try to order in advance to avoid the delay of production.

3. The processing cycle of PVDF color coated aluminum coil is generally longer, mainly because fluorocarbon paint uses Nippon Paint, and Nippon Paint is all standardized and only can be colored after getting the sable laboratory data. It usually takes around 15 days. Of course, if the thickness and specifications of the color coated aluminum coils are conventional products and we have stocks, the delivery time can be shortened to around 7 days. The processing cycle of the color coated aluminum coil with PE coating is slightly shorter, because the color mixing of polyester paint is relatively simple, and the available manufacturers of polyester paint are relatively many. Generally, the processing cycle of polyester coated aluminium sheet/coil is about 2 days. If you like to cooperate with Haomei Aluminum for a long time, we can stock the aluminum gutter coil for you regularly. Facing to overseas market, our PVDF and Polyester coated aluminum coil generally adopt waterproof packaging with moisture-proofing agent inside. PVC Coated Aluminum Coil Stock Haomei PVC coated aluminum coil stock is available in a broad array of textures and colors, which is a low maintenance and durable trim solution. The common alloys are 1xxx,

4. 3xxx and 5xxx aluminum alloys. The textures we provide are stone grain and wood grain. The pre-treatment agent adopts German Henkel and Chemitel, and the paint adopts American PPG paint, Austrian tiger paint, Dutch Akzo paint, and Swedish BECKER paint. At the same time, with the advance coating technology, we provide 20-year weatherproof warranty. The specific processing includes: unwinding, Unwinding, primary coating, primary drying, secondary coating, secondary drying, cooling storage, quality inspection, rewinding, rewinding re-inspection, packaging,etc. Before coating, for getting quality plain aluminum coil, we should also have strict control of the aluminum coil manufacturing process such as alloy elements, smelting, casting,etc. If you like to order the coating aluminum coil of special color, you need to follow the steps below: 1. First, you need to provide a sample of the required color (it is best to use a metal plate as the base material, and other materials are also available, but the color matching accuracy is not as good as the metal plate template). If you know its international standard color number, the operating procedure will be very simple, and the color matching result will be very accurate. You only need to provide the

5. color number to our company’s color experts for confirmation. 2. The new color sample will take about 1 week to finish under normal circumstances. 3. You need to give a written confirmation as soon as possible after receiving the sample. After receiving your confirmation, we will formally arrange the order production according to the order requirements. White Aluminum Coil Stock The paining aluminum trim coil is to color the surface of the aluminum coil to get a better weather resistance and decorative effect. It can be in various ways, including trim around windows and doors, flashing around skylights and dormers, and hobby or household applications. The trim aluminum coil features a smooth finish and is easy to cut, bend, and shape. It is of acid resistance, alkali resistance, corrosion resistance, chalking resistance, decay resistance, ultraviolet radiation resistance, friction resistance, etc. The specification of white aluminium coil: Substrates AA1100, 3003, 3004, 3105, 5006, 5052, 8011, etc. Thickness 0.08-1.5mm Width ＜1800mm Coils core diameter 150mm ,405mm, 505mm, 508mm, 510mm Coating thickness PVDF >=25micron POLYESTER>=18micron Pencil hardness > 2HB Coating adhesive not lower than first grade Impact: no any crack

With high-performance roll coating processing technology, we can can effectively control the size accuracy and ensure uniform color and thickness. The service life can last 20-30 years. Alloys of Textured Aluminum Trim Coil The alloys of textured aluminum trim coil are generally 1100, 3003 and 3004 aluminum coil. Lets have a look of their differences. 1100 aluminum coil belongs to the pure aluminum coil, which has good bending machine processing performance. The advantage is low price and excellent sheet metal processing performance. The disadvantage is that the strength is lower than the 3003 and 3004 alloy. 3003 aluminum coil belongs to aluminum-manganese alloy. Its harness is slightly higher than 1100 alloy, about 20-30% higher. It is moderately priced and strong aluminum alloy. It is also of excellent anti-rust performance.

7. 3004 aluminum coil belongs to the aluminum-magnesium-manganese alloy series with a strength higher than 3003. It is a commonly used aluminum gutter coil substrate in roof construction in recent years. The qualified 3004 aluminum alloy often used in metal roofing and wall systems features light weight, moderate structural strength, weather resistance, stain resistance, and easy welding processing performance. Under normal use, the raw material life is long 50 years. It has the following features: 1. Its tensile strength is150～285 σb (MPa), which is 2.5 times the strength of ordinary aluminum coil. 2. Its corrosion resistance is 3 times that of ordinary aluminum and 2 times that of stainless steel. 3. It can reduce noise, absorb shock and can withstand great impact load. 4. The superior electromagnetic wave shielding performance prevents the human brain from being harmed. 5. It is an ideal environmental protection material, and does not release harmful toxins. As a main alloy of aluminum gutter coil, it can reduce construction cost and extend the service life of roofing system.
