Aluminum color coil types and prices

 

Aluminum color coil falls on three types by processing methods: color coated aluminium coil, mirror finish anodized aluminum coil and brushed anodised aluminium coil.

aluminum color coil

Color coated aluminum coil is the most popular type in either production or application. When we speak of aluminum color coil, we refer to aluminum coil with paint coating if there are no special notes. This type of aluminum coil is obtained by surface cleaning, chromizing, roller coating and baking of a mill finish aluminum roll, featured by light weight, bright color, easy forming property and good corrosion resistance. With epoxy roll coating method, the coil can be coated with paints of PE and PVDF. One side or both sides are painted with desired paints in accordance to demands of clients. The coating thickness has a lot to do with the paint layer number. One-layer coating is from 4μm to 20 μm, two-layer 25μm-28 μm, and three-layer 35μm-38μm. The patterns and colors are diverse. Pure colors can be customized in reference to alcoa aluminum coil stock colors, special patterns include wood grain, stone grain, brick grain, cloth grain and camouflage grain. In addition, an aluminium color coil can even be embossed for specialized purposes like insulation and decoration.

Mirror finish anodized aluminum coil and brushed anodized aluminum coil are less frequently applied, but they take up a market of color aluminum coil that should not be overlooked. The coloring process for them is anodizing, an advanced technology combining chemical and mechanical reactions of aluminium coil rolls. Either it is a mirror coil or a brushed coil, it should be anodized after being polished or brushed, or else the reflectivity and the brushing lines on the coil surface will be damaged during the following anodizing procedure. Mirror anodized aluminium rolls are used in fields taking advantage of their reflectivity, like solar panels, interior decorative panels, labels, ornaments and other reflective panels, and brushed anodized coils in building, furniture, advertising and so on.

Slitting of 1mm 2mm 4mm aluminium strip

图片
What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate ...

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid pu...

Embossed Aluminium Coil Patterns And Applications

图片
If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking,...
