Production and Development of Prepainted Aluzinc Steel Coil
1.1 The production and development history of Prepainted Aluzinc Steel Coil
1.1.1Characteristics of Prepainted Aluzinc Steel Coil
Prepainted Aluzinc Steel Coil, also known as organic-coated steel sheet, pre-coated steel sheet, and color-coated sheet, is a composite material formed after the substrate is pretreated, coated with layers, or multiple layers of organic paint, and then baked. The Prepainted Aluzinc Steel Coil has a bright appearance, good corrosion resistance, easy processing, long service life, less pollution, and practical functions. As a result, it is in various fields such as construction, transportation, household appliances, furniture, and office appliances.
In the construction industry, various color-coated profiled steel plates have apparent advantages in meeting construction needs, shortening the construction period, and reducing maintenance costs. Prepainted Aluzinc Steel Coil has coatings and coatings suitable for use in various environments, varied profiles of profiled steel sheets, easy-to-operate construction techniques, and colorful colors, making color-coated steel sheets extraordinarily flexible and adaptable. Compared with wood, concrete, and other building materials, Prepainted Aluzinc Steel Coil has unique properties and has become the primary material of contemporary building envelopes.
In the light industry and household appliances industry, Prepainted Aluzinc Steel Coil can be directly processed into refrigerator panels, side panels, washing machine boxes, air conditioner outdoor unit shells, etc. by rolling, stamping, or bending, without degreasing, phosphating, painting and other processes, thus reducing equipment Investment, reduce processing procedures, avoid environmental pollution, etc. As a result, Prepainted Aluzinc Steel Coil has been widely used in the global home appliance industry.
1.1.2 Development of Prepainted Aluzinc Steel Coil at Home and Abroad
Prepainted Aluzinc Steel Coil was produced in the United States in the mid-1930s, starting with narrow-band paint to manufacture blinds. The United States built the first wide-band coating units in the 1950s. In the 1960s, Prepainted Aluzinc Steel Coil was rapidly developed in the United States, Europe, and Japan.
