The most reflective metals in the world are silver and aluminum. Reflective aluminum or "lighting sheet" has a mirror like surface and is made from high purity aluminum with specific photometric qualities to control light. But, do you know how the reflective aluminum sheets make out? Here are some key process:
First, we need get high-quality aluminum sheet. To make a mirror, the surface must already be very smooth. This is often done by rolling the aluminum between highly polished steel rollers.
The sheet is polished using special abrasive belts or brushes. This is like sanding wood to make it smooth, but much more precise. This step removes any small imperfections and creates a smooth, shiny base.
The polished sheet is thoroughly cleaned with chemicals. This removes all dirt, grease, and oils from the surface. A perfectly clean surface is essential for the next steps.
This is the most important step for creating the true mirror effect.
The clean aluminum sheet is placed in a special chemical bath.
An electric current is passed through the bath and the aluminum.
This process dissolves a tiny, even layer from the surface, smoothing it out at a microscopic level. It erases the tiny scratches left by mechanical polishing, resulting in a flawless, reflective surface.
To protect the soft mirror finish from scratches and corrosion, it is often anodized.
The sheet is placed in another chemical bath (usually sulfuric acid) and an electric current is applied.
This process creates a hard, clear, protective oxide layer on the surface. This layer is very thin and transparent, so it does not reduce the reflectivity.
Important: For a true mirror, the anodizing layer must be kept very thin. A thicker anodized layer, can slightly lower the reflectivity.
In short, the process is: Smooth Rolling → Mechanical Polishing → Chemical Cleaning → Electrolytic Polishing → (Optional) Thin Anodizing.
The result is a durable aluminum sheet with a reflectivity that can be as high as 85-95%, functioning like a mirror.

Advantages of mirror aluminum sheets for reflections:
Lighting: Mirror aluminum sheets boost light brightness and distribution in fixtures like lamps, reflectors and covers.
Solar Energy: They reflect and concentrate sunlight onto receivers in CSP systems for heat or electricity conversion.
Interior Design: Used for decorative elements (wall panels, ceilings, furniture) and mirrors in bathrooms/dressing rooms.
Architecture: Applied in building facades, cladding, decorative parts, plus reflective surfaces in public spaces and art installations.
In order to protect the reflective mirror aluminum sheets's shiny surface free from scratches, we can pack the mirror aluminum sheets like these steps:
Step 1: Cover the Surface
Wear gloves to avoid fingerprints.
Stick a special peel-off plastic film onto the shiny side. This is the best protection.
If you don't have film, put a clean, soft paper between sheets.
Step 2: Make a "Sandwich"
Place the sheet between two pieces of stiff cardboard or foam that are larger than the sheet.
This protects the edges and stops the sheet from bending.
Step 3: Put in a pallet or in a box.
Place the "sandwich" into a strong cardboard box.
Fill any empty space with packing material so it can't move around.
For many sheets, a strong wooden crate is best.
