Aluminum Coil Stock for Sale

1. Aluminum Coil Stock for Sale Abstract: For meeting different applications, there are rich kinds of aluminum siding trim coil, brushed aluminum coil, aluminum with Polysurlyn moisture barrier,aluminum coil with Kraft paper,embossed aluminum coil,etc. Color and Paint of Aluminum Siding Trim Coil The aluminum trim coil colors is usually toned according to Ral or Pantone color card (PANTONE). Haomei aluminum trim coil has over 300 hundred colors for the customers to choose from such as Cappuccino, Clay, Coffee, Espresso, Silver Metallic, Tan, and White. The customers also can provide the color card code or send the sample to us, we can color the colors according to your requirements. It is produced by internationally advanced roller coating technology to ensure that the surface of color coated aluminum coil is dust-free and no color

2. difference. There are also different kinds of paint for the customers to choose from: Acrylic, Polyester, Polyurethane,Epoxy and Fluorocarbon. Acrylic: The paint film has high hardness, but it has poor flexibility, so it is used to make high-hardness coatings such as automotive paint. Polyester: Its film hardness is a little power than the Acrylic, but it has good flexibility and processability, which is a common paint for the aluminum coil stock. Polyurethane: The paint film has good toughness, good adhesion, wear resistance, but easy to yellow and chalk, which is generally used as a primer of the PVDF coating. Epoxy: The paint film has good adhesion, corrosion resistance and wear resistance, but high brittleness, so it is generally used as the back paint of the aluminum trim coil. Fluorocarbon: The paint film has excellent corrosion resistance, super long weather resistance and strong adhesion, but the paint film is soft. The aluminum coil paint usually choose PVDF and FEVE. Brushed Aluminum Coil Suppliers The brushed aluminum coil is a manufacturing process that repeatedly uses sandpaper to scrape the aluminum coil out of line. The process flow is mainly divided into three parts: deesterification, sand mill, and water washing. In the brushing process, the special coating technology after anodizing can make the surface of

3. the aluminum coil generate a coating layer containing the metal component, clearly showing each tiny trace, so that the metal matte will appear fine silk luster. The metal shell of many products choose this process to make the product has both fashion and technology elements. The brushing process is to be done after stamping. The brushed aluminum coil can be made into straight grain, chaotic grain, thread grain, corrugated grain and spiral grain,etc. The straight grain refers to the processing of parallel lines on the surface of aluminum coils by friction with mechanical equipment. There are two types of straight-grained metal wire drawing: continuous wire and intermittent wire. The continuous wire is obtained by rubbing the surface of the aluminum coil with a wiping cloth or a stainless steel brush based on continuous horizontal parallel lines. Intermittent wire is generally produced in brush milling machines or rubbing machines. The chaotic grain of the aluminum coil is a kind of irregular and obscure grain obtained moving the aluminum plate up and down, left and right under the high-speed copper wire brush. The corrugated pattern is generally made in a brush milling machine or a rubbing machine. Use the radial exercise of the upper group of grinding rollers to rub the surface of the aluminum coil to get the grain. The tread grain is to make use of the rotation of the felt and the parallel movement of of the pallet to get an external thread pattern with the same overall width. The spiral grain is mostly used in the production and processing of circular identification plates and small and medium-sized decorative art dashboards. Aluminum with Polysurlyn Moisture Barrier The aluminum with Polysurlyn moisture barrier is the close combination of the Polysurlyn and the aluminum coil through the high-pressure hot pressing process. The thickness of Polysurlyn film. The wight per square meter is 0.08 kg. After being laminated with the aluminum coil, it cannot be torn off without cracking. The Polysurlyn film is of excellent weather resistance and durability. After thermal composite bonding, it can still maintain excellent bonding under severe and harsh conditions such as heat aging, hot water, cold water, and low temperature. The Polysurlyn laminated aluminum coil is suitable for multiple industries such as household appliances, building decoration, thermal insulation, luggage, shoe materials, automotive interiors, furniture, etc. Its manufacturing process includes: a. preheating of the equipment; b. Place the aluminum in the

4. preheated equipment for automatic trimming, hot pressing compounding and online shaping; c. Place the Polysurlyn coating on the plain aluminum coil or color coated aluminum coil; d. The aluminum coil with the Polysurlyn film is compounded at a certain temperature; e. After cooling, automatic cutting, and shearing, we get the finished product. The aluminum with Polysurlyn moisture barrier is of low price, light weight, environmental protection and effective heat insulation. Its specific advantages include: 1. The thickness of the Polysurlyn film(0.08 mm) increases its weather resistance. 2. It absorbs water vapor and will not release water vapor. 3. It has low flammability after compounding. 4. The aluminum coil with Polysurlyn film is more waterproof than color coated aluminum or aluminum coil with Kraft paper. 5. The series 1, 3 and 5 aluminum coil are all compounded with Polysurlyn film. Aluminum Coil With Kraft Paper Aluminum coil with Kraft per is an kind of aluminum insulation coil which is popular in recent years. It is widely favored in the Middle East countries. The thickness is generally 0.2-2.0mm and the width is between 800-1300 mm. The alloys are 1060,1100, 3003,3004,3104 and 5052 aluminum coil. There are three processes for the aluminum metal jacket with Polykraft moisture barrier: 1. The Kraft paper is self-adhesive and it is directly pasted on the aluminum coil. Advantage: This process is of low production cost, high production efficiency and timely delivery. Disadvantage: The surface of kraft paper is prone to air bubbles due to temperature changes,

5. which affects the bonding effect. The open-air storage time should not be too long. And it is very easy to fall off, thus affecting the quality of construction. 2. The Kraft paper and aluminum roll are bonded together by heating. This process is newly developed by Haomei Aluminum. Advantage: The adhesion is very high, and the glue will not open or fall off for 24 hours in the water immersion test. The weather resistance is extremely high, and the Kraft paper is not affected by temperature changes. Disadvantage: The production efficiency is slow and the production cost is too high. 3. The aluminum coil with Kraft paper can be further processed to make embossed aluminum roll and aluminum tile covered with Kraft paper. During the production of Polykraft laminated aluminum coil, the aluminum coil must be degreasing. The shape must be flat. The weight of each roll can be 2.5 -3 tons or 3.5 tons can be used. The inner hole is made of 505 paper tube core or aluminum core. We adopts the fumigation-free packaging for sea shipping. As a professional aluminum coil manufacturer, we choose the heat pressing process. It cannot be torn off by hand. It does not crack if it is immersed in the water for 24 hours. Surface Treatment of Embossed Aluminum Coil Embossed Aluminium sheet also called stucco embossed aluminium sheet, is a kind of aluminum plate which forms a variety of decorative pattern on the surface after calendering processing. It is widely used, mainly in packing, building, curtain wall, etc. The sandblasting method is very suitable for the surface treatment of the embossed aluminum coil. At present, there are several sandblasting methods. Lets’ have a look together.

6. 1. Sandblasting: It makes use of the high-speed sand flow to roughen the metal surface. The ore or river sand is used. 2. Brushing: Under the continuous rotating of the round copper wire brush, the aluminum coil moves forward while moving left and right to get the sandblasting surface. 3. Frosting: The plate grinding machine eliminated by offset printing can be used to grind aluminum plate, but it needs to be washed with water continuously to get a fine and glossy surface effect. 4. Chemical method: There is a special chemical sandblasting surface treatment agent. Through chemical treatment, we also can get an ideal stucco embossed aluminum coil.
