Brushed aluminum is a new type of building material. With its unique surface treatment technology and environmental protection advantages, it is gradually being widely used in various fields.
It has a strong sense of reality and three-dimensionality, realistic effect, clear texture, unique pattern and wear resistance.
Brushed aluminum coils and sheets are widely used in building curtain walls, roofs, interior and exterior decoration, fine doors and windows, signs, lighting covers, brushed aluminum housings of household appliances, and our common electronic product housings.

Brushed aluminum coil classification
Color-coated brushed aluminum coils can be made into Linear brushing, random brushing, spiral lines, corrugations and spiral lines according to decorative needs.
Linear brushing
Straight wire drawing refers to the process of machining straight lines on the surface of aluminum plates by mechanical friction. It has the dual functions of brushing away scratches on the surface of aluminum plates and decorating the surface of aluminum plates. There are two types of straight wire drawing: continuous wire drawing and intermittent wire drawing.
Random brushing
Under the high-speed copper wire brush, the aluminum sheet is moved back and forth and rubbed left and right to obtain an irregular, inconspicuous matte line texture. This processing has high requirements on the surface of the aluminum sheet.
Wavy brushing
It is usually carried out on a brushing machine or a rubbing machine. The axial movement of the upper set of grinding rollers is used to brush the surface of the aluminum sheet to form wavy patterns.
Spiral Brushing
A kind of silk pattern is obtained by rotating and polishing the surface of aluminum plate with cylindrical felt or grinding stone nylon wheel mounted on a drilling machine and rotating and polishing with kerosene and polishing paste. It is mostly used for decorative processing of round signs and small decorative dials.
Thread drawing
A small motor with a circular felt on its shaft is fixed on the workbench at an angle of about 60 degrees to the edge of the workbench. A slide plate with a fixed aluminum plate is used, and a polyester film with a straight edge is attached to the slide plate to limit the thread race. The rotation of the felt and the linear movement of the slide plate are used to rub out thread lines of uniform width on the surface of the aluminum sheet.
Cross brushing
It is usually made on a brushing machine or a rubbing machine. The aluminum sheet passes through two sets of rollers to extrude cross patterns on the surface of the aluminum sheet.
Color coated brushed aluminum coil application
Architecture
In terms of building curtain walls, color-coated brushed aluminum coils have great advantages in appearance design and can create curtain wall effects of various forms and styles .
color-coated brushed aluminum coils can be used to make lightweight roof structures, increase the roof's load-bearing capacity, and effectively reduce roof temperatures .
color-coated brushed aluminum coils can be used to make door and window frames, wall panels and other decorative materials, which can beautify and decorate the visually .
Electrical enclosure
color-coated brushed aluminum coils can be used to make casings for laptops, mobile phones and other products to increase the texture and grade of the products.
Logo and Signage
Due to the good durability and visual effects of color-coated brushed aluminum coil, it is also widely used in the production of logos and signs to enhance their recognition and aesthetics.
Auto industry
In the automotive industry, color-coated brushed aluminum coils are used to make parts such as car bodies, doors, and trunks. Due to its light weight and high strength, the use of brushed aluminum coils can reduce the weight of the car and improve fuel efficiency.
Worthwill color coated brushed aluminum coil
Worthwill has invested heavily in research and development, debugging equipment , and technical personnel have worked overtime to solve problems. Now, we can perform meticulous wire drawing on aluminum materials . Stable wire patterns, adjustable depth, and full roll wire drawing have become the most basic features of Worthwill color coated brushed aluminum coil.
Further advantages: 1. The length of the wire pattern can be adjusted; 2. Multi-directional wire drawing can be performed in the same processing .
According to customer needs, the angles between multi-directional silk patterns can be adjusted, which greatly reduces costs .
Color-coated brushed aluminum coil has become one of the indispensable materials in modern architecture and decoration due to its rich color selection, excellent weather resistance, strong mechanical properties and environmental protection characteristics.
