Product Introduction and Common Specifications

Al-Zn Coated Steel Coil is a steel product with aluminum-zinc alloy coated on the steel surface. It forms a protective layer with excellent corrosion resistance by evenly coating the aluminum-zinc alloy coating on the steel base. It is widely used in many industries such as construction, automobiles, and home appliances. Compared with traditional galvanized materials, Al-Zn Coil has more advantages in corrosion resistance, high temperature resistance, and weathering resistance, and is suitable for a variety of harsh environments.

Product Application and Advantages

Different surface treatment methods can be customized according to different application requirements, such as mirror, frosted or color coating. The wide application of Al-Zn Coil is mainly concentrated in the construction industry, such as anti-corrosion materials such as roofs, walls and gutters; protection of electrical housings in the home appliance industry; anti-corrosion materials for body and chassis in the automotive industry; and in the energy industry for manufacturing solar panel backplanes and energy storage devices. With its excellent resistance to high temperatures and UV rays, galvanized coils are also widely used in energy, pipelines, metal furniture and other fields.

The advantages of galvanized coils are mainly reflected in their excellent corrosion resistance, high temperature resistance, weathering resistance and good processability. Due to the dual protection of the aluminum-zinc coating, galvanized coils have a longer service life than traditional galvanized materials, and are particularly suitable for applications exposed to harsh weather conditions for a long time. In addition, galvanized coils have good processability and are suitable for a variety of processing methods such as cutting, bending and welding, which can meet the needs of different customers. At the same time, galvanized products meet environmental protection requirements and are increasingly favored by green buildings and sustainable development applications.

Product quality inspection methods

In terms of quality inspection process, the production process of galvanized coils needs to undergo strict quality control. First, the chemical composition and mechanical properties of the raw materials are tested to ensure that they meet the production standards. Secondly, the coating thickness and uniformity need to be checked by special equipment to ensure that the coating quality of each roll of products meets the standards. The surface quality will also be strictly inspected to ensure that there are no defects such as cracks, bubbles or scratches. In addition, mechanical property tests (such as tensile and bending tests) and corrosion resistance tests (such as salt spray tests) are key links to ensure product quality. The final product will be packaged and inspected before shipment to ensure that it meets transportation requirements.
