Stone Facade Construction Cladding System Kerf Bracket

What treatments are needed on the surface of the upper and lower cladding system brackets to improve the adhesion and anti-corrosion effect of the coating?

When discussing the surface treatment solutions provided by Jiangsu Aozheng Metal Products Co., Ltd. for upper and lower cladding system brackets, we have to first emphasize the company's strong mold and custom tooling team and excellent production capabilities. These advantages provide high-quality, Diversified stent products lay a solid foundation. As a metal products manufacturer with an annual production capacity of more than 2,000 tons, we are not only able to meet the diverse needs of domestic and foreign markets, but also strive for excellence in product details to ensure that each product can meet or even exceed customer expectations.
For upper and lower cladding system brackets, the importance of surface treatment is self-evident. Good surface treatment can not only significantly improve the adhesion of the coating, but also effectively enhance the anti-corrosion performance of the bracket, thereby extending its service life and reducing maintenance costs. Jiangsu Aozheng Metal Products Co., Ltd. relies on its rich industry experience and technology accumulation to customize a series of scientific and efficient treatment processes for the surface of the stent, including the following key steps:
1. Surface cleaning and degreasing
The bracket must undergo a rigorous cleaning and degreasing process before any surface treatment. We use advanced physical and chemical methods, such as high-pressure water jet cleaning, solvent degreasing, etc., to completely remove oil, dust, rust and other impurities on the surface of the bracket, laying a solid foundation for subsequent coating adhesion. This process ensures a tight bond between the coating and the substrate, avoiding peeling or blistering of the coating due to dirty surfaces.
2. Surface pretreatment
The bracket will receive surface pre-treatment, such as sandblasting or pickling and phosphating. Sand blasting uses high-speed jetting of sand particles to impact the surface of the stent to form a uniform and rough microstructure, which helps to increase the contact area between the coating and the substrate, thereby significantly improving the adhesion of the coating. Pickling and phosphating can form a dense phosphate conversion film on the surface of the stent. This film not only has good anti-corrosion properties, but also provides an ideal adhesion interface for subsequent coatings.
3. Anti-corrosion primer coating
After completing the surface pretreatment, the bracket will enter the painting process. Jiangsu Aozheng Metal Products Co., Ltd. uses high-quality anti-corrosion primers. These primers usually contain anti-rust pigments and resin components, which can effectively isolate the bracket from corrosion by air, moisture and corrosive substances. Through professional spraying equipment and technology, ensure that the primer is evenly and densely covered on the surface of the bracket, forming a strong anti-corrosion barrier.
4. Topcoat application and curing
After the primer is fully dry and reaches the specified requirements, the bracket will be painted with topcoat. The choice of topcoat not only takes into account aesthetics, but also factors such as weather resistance and wear resistance. We offer topcoat options in a variety of colors to meet the aesthetic needs of different customers. After the coating is completed, the bracket will enter the drying room for curing treatment. By controlling the temperature and time, the coating will be fully cross-linked and cured to achieve the best performance.
5. Quality inspection and packaging
Finally, each batch of stents will undergo strict quality testing, including coating thickness testing, adhesion testing, anti-corrosion performance evaluation, etc., to ensure that every product meets international standards and customer requirements. Products that pass the test will be carefully packaged and prepared to be shipped to Europe, the United States, Saudi Arabia and other parts of the world to provide stable and reliable support for various upper and lower cladding systems.
Jiangsu Aozheng Metal Products Co., Ltd. relies on its professional mold and custom tool team, strong production capacity and scientific surface treatment process to provide excellent anti-corrosion and coating adhesion solutions for upper and lower cladding system brackets. We are committed to providing customers with high-quality, high-performance products and services to contribute to the sustainable development of the global construction industry.
