What Is Aluminum Trim Strip

The aluminum trim strip is usually a kind of color coated aluminum strip, adopting a two-coating and two-baking process, that is, after the surface pretreatment of the aluminum coil, the primer (primary coating) and topcoat (finishing coating) are applied and baked twice. It can carry out back coating and embossing or printing processing as needed.

One of its main application is ceiling. In suspended ceilings made of mineral fiber panels, colored aluminum strip can enhance the decorative appearance of the ceiling support structure. This narrow, thin coated aluminum strip is often used to cover the surface of T-rails. The aluminum strip ceilings are being manufactured in different widths and at any desired length.

According to the type of coating, pre-coated aluminum coils can be divided into two categories: PVDF coated aluminum coil and PE coated aluminum coils. Fluorocarbon pre-coated aluminum coils are aluminum products with excellent weather resistance, UV resistance, chemical corrosion resistance and self-cleaning properties.

Polyester pre-coated aluminum coil refers to coating the surface of the aluminum coil with coating containing polyester resin to form an aluminum product with good adhesion, rich colors and environmental protection performance.

It consists of a three-layer structure, namely aluminum alloy substrate, aluminum oxide film and coating. The aluminum alloy substrate is the supporting layer of colored aluminum, which provides the strength and toughness of colored aluminum. Generally, 3000 series or 5000 series aluminum alloys are used. The coating is a decorative layer of colored aluminum that is cured at high temperatures and can appear in various colors and patterns.

The roller coating method refers to applying the organic coating evenly on the aluminum coil through a roller coater after pretreatment on the surface of the aluminum coil, and then through drying, solidification, cooling and other processes to form a color coating with a certain thickness and performance. The roller coating method can achieve single-sided or double-sided color coating, or multi-layer or multi-color color coating to meet different needs and effects.

The color coated aluminum strips for sale are processed from aluminum coils through slitting equipment, so the processing thickness and tolerance of the aluminum strips are closely related to the slitting equipment. Our aluminum flexible strip slitting equipment comes from Germany, which can effectively control the width tolerance. The tolerance can be controlled within 0.05mm. Currently, it can slit aluminum strips with a thickness of 0.15-3.0mm, ensuring no scratches and accurate width tolerance control.

Aluminium Strip 30mm for Ceiling

Aluminum strip especially color coated aluminum strip is manufactured in different widths and at any length to cover the surface of the T-rail of ceilings, thus enhancing the decorative appearance of ceiling support structures. Aluminium strip 30mm is a likely choice. The colors can be chosen from Ral or Panton colors.

Aluminum strips are generally cut according to the actual width of the user, which can reduce waste, reduce processing (no cutting), and save raw material costs. The aluminum strip ceiling adopts 5052 aluminum alloy. The coating chooses polyester painting. Haomei coating system guarantees a perfect surface finish and optimum paint adhesion, as well as tight bend radii at the edges.

The main two paints for painted aluminum ceiling strip are fluorocarbon (PVDF) and polyester (PE). The paint colors and effects between the two can be same, but the price gap between the two is not small. The main reason is that the cost of painting between the two is quite different. Fluorocarbon paint contains fluorine, which has better weather resistance, longer service life and higher price.

The coating process is a critical step in the production of colored aluminum strip coil, which directly affects the final coating quality and product durability. Therefore, the coating process is very strict. With the continuous improvement of coating equipment and the development and utilization of new coatings, the production of coated aluminum coils is more mature, and the processing costs are also falling. The color coated aluminum strips/coils have therefore developed rapidly.

The main processing equipment of the aluminum strip is the slitting unit, which can be divided into the required length and width according to the needs. Of course, the equipment for strip processing is universal, and copper coils can also be processed, and the processed products are called copper strips.

One important quality index of the aluminum alloy product is the precision. The width precision of Haomei aluminum strip for ceiling can reach plus or minus 0.03mm, and the thickness can be controlled within plus or minus 0.01mm. The improvement of precision can reduce scrap rate and improve production efficiency. Welcome to leave message below to inquire aluminum strip ceiling price.

What Is Manufacturing Process of Coated Aluminum Strip Roll

The roll coating process is an effective method of applying organic protective coatings on the aluminum strip roll. It is a continuous, highly automated process that produces a consistent product compared to post-coating methods.

Raw material input

The raw aluminum coil is sent to the production line, and is smoothed by the smoothing machine. This step ensures the smoothness of the product. The aluminum coil enters the stocker. There are two scrolls here, to ensure that one of them is always in a standby state.

Cleaning and pretreatment

The pretreatment of the aluminum coil is repeated by water spraying. This method is more effective than the traditional method. The water can also be reused, reducing energy consumption.

Pretreatment can improve the corrosion resistance of the product and improve the adhesion of the coating. At this stage, the conversion coating is chemically formed on the aluminum surface.

Coating

The coating process is mainly divided into two stages, namely base coating and top coating. In the first stage, the aluminum coil is passed through a roll coater and is primed on one or both sides. After drying, the aluminum coil passes through a second roller coater, at which time one or both sides of the aluminum coil are coated with topcoat.

A typical coating system requires the product to have formability, scratch resistance, attractive appearance, good weather resistance, paintability, etc. To achieve these different effect properties, coatings include: acrylic resin primers, polyester, polyurethane or fluorocarbon.

Curing

The color coated aluminum strip passes through the curing oven, and the temperature is set at a temperature adjusted to ensure that the volatiles on the aluminum strip are removed and the coating is cured. According to the needs of the coating system, the curing temperature is set between 200 and 300 degrees Celsius, which is the key technical point to ensure the quality of our products.

In addition, in order to protect the environment and control costs, the mist of the solvent is evaporated at high temperature to heat the curing oven.

Subsequent processing

Coated aluminum coils can be further processed into aluminum strip roll or embossed aluminum coil.

The Manufacturing Process of Thin Flat Aluminum Strips

Aluminum strip stock is the product of aluminum coil after slitting, and the width is narrow, which is suitable for the use of transformer manufacturing, hardware lighting processing and window spacer. Usually aluminum strips are cut according to the actual width of the user, which can reduce waste, reduce processing procedures (without cutting), and save raw material costs.

The production of cold-rolled aluminum strips all need to go through production processes such as cold rolling, finishing and heat treatment. The difference in production processes is mainly in the production method of cold-rolled billets. At present, there are three main production processes: casting and rolling, ingot hot rolling and continuous casting and rolling.

The casting and rolling process is to directly cast the molten aluminum into a 6mm-8mm cast-rolled coil, and then adopt cold rolling method. Ingot hot rolling process is to semi-continuously cast aluminum liquid into large flat ingots. After the ingots are sawed, milled and edged, and heated, they are first sent to the hot rolling mill to be processed into hot rolled coils, and then cold rolled.

The continuous casting and rolling process is between the casting and rolling process and the slab hot rolling process, and there are many forms. Generally, molten aluminum is continuously cast into slabs of a certain size (thickness is much thinner than that of large slabs), and the high-temperature slabs are directly sent to hot rolling mills for rolling.

Today, the continuous casting and rolling process of thin slabs, which can save energy and reduce consumption and reduce production costs significantly, has attracted more and more attention. For example, for the production of 1mm-2mm aluminum, the continuous casting and rolling process only needs smelting, continuous casting and rolling to achieve.

The casting and rolling process requires smelting, casting and cold rolling to achieve. The flat ingot hot rolling process requires smelting, semi-continuous casting, sawing head and tail, milling, ingot heating, hot rolling, (cold rolling) to achieve. It can be seen that continuous casting and rolling belong to a short manufacturing process.

The main processing equipment of the thin flat aluminum strips is the slitting unit, which can cut the flat aluminum strips into the required length and width according to the needs. Haomei Aluminum owns two aluminum strip slitting production lines, which can cut aluminum strips according to the width required by users. For products with high surface requirements, film can be applied during the slitting process to avoid scratches.

The cutting accuracy of aluminum strip can be controlled within 0.05mm, and the inner and outer diameters can be processed according to user requirements. Welcome to leave message below to inquire what you need.
