White orange-peel embossed coil-coated metal sheet

White orange-peel embossed coil-coated metal sheet is a building material that combines decorative appeal with practicality. Typically utilizing aluminum-magnesium-manganese alloy or color-coated steel as the substrate, it features a uniform orange-peel texture created through mechanical embossing and a white topcoat applied via a pre-coating process; it is widely used in roofing and wall cladding applications. Substrate Selection: Commonly made from 3003/3004 aluminum-magnesium-manganese alloy (though galvanized steel is also an option), the material typically ranges from 0.2 mm to 2.5 mm in thickness. It offers low density, imposes minimal structural load, and possesses excellent bending resistance, making it suitable for subsequent roll forming and bending processes. Coating Process:Manufactured using an automated pre-coating process involving "two-coat/two-bake" to "four-coat/four-bake" cycles. The white topcoat usually consists of polyester or fluorocarbon (PVDF) materials, with a front-side coating thickness of up to 25 μm; the reverse side features a specialized anti-corrosion coating, ensuring strong resistance to UV-induced aging. Orange-Peel Texture: A uniform, textured orange-peel pattern is created through mechanical embossing. This enhances surface slip resistance and minimizes the visual impact of minor scratches. The white finish is dirt-resistant and easy to clean, maintaining a fresh appearance even after long-term use.
