Over 300 skillful workers,with over 200 major projects completed worldwide,our workers pride themselves in production high quality products and taking on projects with a high level of difficulty in fabrication and coating.

In our trade with merchants of various countries,we always adhere to the principle of equality and mutual benefit.It is our hope to promote,by joint efforts,both trade and friendship to our mutual advantage.

Specification

With regard to "Aluminum Roller with RAL colour specification", i.e. an aluminium roller with RAL colour specification, this usually means that the colour of the surface coating of the aluminium roller is specified in accordance with the RAL colour specification system. The customer or manufacturer can select the exact colour required according to the code in the RAL colour specification system, thus ensuring colour accuracy and consistency of the product.

For example, if a particular aluminium drum needs to be painted RAL 9010 (i.e. pure white), the manufacturer can find the appropriate paint according to this code and apply it to the surface of the aluminium drum. This standardised colour system helps to reduce communication misunderstandings and colour variations, improving productivity and product quality.

Characteristic

The characteristic of prepainted aluminum coil can be summarized as follows:

Durability and Corrosion Resistance: The prepainted aluminum coil is coated with a protective layer that significantly enhances its resistance to corrosion and weathering. This coating layer helps to prevent oxidation, discoloration, and other forms of degradation, ensuring a longer lifespan for the material.

Excellent Appearance: The prepainted aluminum coil offers a wide range of colors and finishes, allowing for a customized aesthetic appearance. Whether it's a matte, gloss, or textured finish, the coating can be tailored to match the desired design and visual effect.

Lightweight and Strong: Aluminum, as a material, is inherently lightweight but also possesses excellent strength and rigidity. This combination of lightness and strength makes the prepainted aluminum coil an ideal choice for various applications, including roofing, cladding, and interior decoration, where weight reduction is crucial.

Easy to Process and Install: The prepainted aluminum coil is available in rolls or coils, which makes it easy to transport, handle, and process. It can be cut, bent, and shaped according to the specific requirements of the project, facilitating efficient installation and assembly.

Environmental Friendliness: Aluminum is a recyclable material, and the prepainted aluminum coil can be reused or recycled after its initial use, reducing waste and environmental impact. Additionally, some coatings may be formulated with environmentally friendly materials, further enhancing its sustainability.

Cost-Effective: Compared to other materials, prepainted aluminum coil often offers a cost-effective solution. Its durability and longevity mean that it can provide long-term value for the investment, while its ease of processing and installation can help to reduce overall project costs.

Advantages

The use of aluminium rollers in washing machines, combined with the surface coating specified in the RAL colour code, offers the following advantages:

High energy efficiency and long service life: Aluminium rollers have better thermal conductivity and lower electrical resistivity than other materials, which means that during the operation of the washing machine, the temperature rise of the aluminium roller is lower, which reduces energy loss and saves energy. At the same time, this characteristic also helps to protect the machine's operational stability and extends the life of the washing machine.

Lightweight and portable: aluminium is inherently lighter, making the entire washing machine lighter. This not only reduces the cost of transport and installation, but also improves the user's portability, especially when it comes to moving or adjusting the position of the washing machine.

Good corrosion resistance: The aluminium drum surface has been treated with a coating specified in the RAL colour code, which enhances its corrosion resistance against water and other chemicals and ensures that the washing machine operates reliably even in wet environments.

Outstanding appearance and consistency: The RAL colour code system ensures the accuracy and consistency of the colour of the coating on the surface of the aluminium drum. This gives the washing machine not only excellent performance, but also an aesthetically pleasing appearance that matches the aesthetics of the modern home.

Environmentally friendly: Aluminium is a renewable metal material and the use of aluminium drums helps to reduce environmental pollution and resource consumption. At the same time, many of the paints in the RAL colour-coded system also meet environmental standards, further reducing the environmental impact of the washing machine.

2.We Dipped In The Coated Aluminum Industry More Than 30 Years.
From 1992, We started from a school subsidiary house for printing the paper. Then we went up year by year. We went through the Asian financial crisis in 1997, the global financial crisis in 2008,then became more and more stronger, in order to save energy for our company, Our market from developed countries such as U.S., U.K. to South-east countries, then back to Europe and Domestic market. We have owned more and more clients feedback due to the well reputation from the crisis.

3.We Export The Coated Aluminum Products More than 100 Countries worldwide.
It is the most important that we are well known the requirement from different countries with different standards. FromAmerican stand to Europe Standard, We can easy to identify and strictly according to it. Also we are well know the different rule from different countries such as American clients well need the thickness in plus tolarance,but it should be minus tolarance thickness in south-east asia and Africa area.

4.We Never use the Re-Cycle Alumiunm Material.
All of us know that aluminm are the re-cycle alloy that can save energy for our earth. but most of the color coated aluminum products are used in very strict and inclement weather district. The re-cycle aluminum can not staisfy the requirement of it . That's why we can continue our business for more than 30 years here and this is the reason why more and more clients choose us with our coated aluminum products.
