High Polished Aluminum Sheets

2026-08-05

In high-end architectural interiors, precision equipment panels, and brand identity systems, the surface consistency, flatness precision, and processing yield of polished aluminum sheets directly determine the upper limit of the final product's quality. Most products on the market have vague definitions of polishing grades, often resulting in large batch color differences, warping of large-size sheets, and surface cracking after bending, increasing processing losses and delivery risks for customers. Haomei Aluminum, leveraging over a decade of experience in exporting high-end aluminum materials, has created high polished aluminum sheet products. With quantifiable precision indicators, a multi-substrate compatibility system, and end-to-end quality control, it provides stable and reliable polished aluminum sheet solutions for global customers.

Haomei Aluminum abandon the vague division of "mirror finish/ordinary polish," classifying highly polished aluminum sheets into three quantifiable grades based on surface roughness and optical performance, allowing customers to precisely select the appropriate type according to their needs.
Standard polished aluminum sheet, surface roughness Ra≤0.08μm, visible light reflectivity 85%-88%, smooth and uniform surface without obvious scratches, suitable for ordinary decorative panels, signage back panels, etc., balancing cost and texture.
High-gloss polished aluminum sheet, surface Ra≤0.04μm, reflectivity 89%-92%, clear and distortion-free imaging, mostly used in high-end interior decoration, lamp reflectors, brand display stands, and is currently the mainstream choice for overseas engineering orders.
Ultra-high precision polished aluminum sheet, surface Ra≤0.02μm, reflectivity 93%-95%, surface close to optical-grade mirror, suitable for precision optical instruments, high-end equipment control panels, and other fields with stringent requirements for reflective precision.

The base material selection is not limited to pure aluminum. In addition to commonly used 1060 and 1070 high-purity aluminum base materials, we also offer high polished aluminum sheets made of 5052 and 6061 alloys. While ensuring a delicate polishing effect, this significantly improves the strength and deformation resistance of the sheet material, meeting the load-bearing requirements of structural components and outdoor panels. Product thickness ranges from 0.3mm to 6.0mm, with a standard maximum width of 1500mm. Custom cutting and leveling to specific lengths are supported, precisely matching customer cutting dimensions and reducing waste.

Addressing the industry pain point of warping in large-size polished sheets, we add a multi-roller precision leveling process after polishing to ensure the flatness of the sheet material is ≤0.3mm/m², resulting in a smooth fit after installation without local protrusions or gaps. For surface protection, different types of protective films can be matched according to the customer's processing technology: low-adhesion PE protective film is used for regular storage and transportation, while special laser film is suitable for laser cutting scenarios to avoid burns and scratches during processing; the finished product surface is simultaneously passivated to form a dense anti-oxidation layer, delaying natural oxidation and loss of gloss. In coastal areas with high salt spray, a transparent anodizing sealing process can be added to further improve weather resistance and lifespan.

As a reliable mirror polished aluminum sheet manufacturer, each batch of our products comes with roughness, gloss, and flatness test reports, with traceable parameters that meet international market access requirements. Packaging uses full wrapping with moisture-proof paper and reinforced with solid wood pallets, suitable for ocean shipping environments, reducing the risk of transportation damage. At the same time, our technical team can provide targeted recommendations on substrate and polishing grade selection based on the customer's application scenario, usage environment, and processing technology, helping customers find the optimal balance between cost and performance.

From precise grading of polishing processes to scenario-based substrate and protective configurations, Haomei high polished aluminum sheets always focus on end-user needs, committed to solving customers' actual pain points throughout the entire process of procurement, processing, and installation. Currently, our products are widely used in numerous high-end commercial decoration and precision equipment manufacturing projects worldwide, and have gained continuous recognition from customers thanks to their stable quality and professional service.
