Anish Kapoor Stainless Steel Sky Mirror
Concave mirror discs pressed from AISI 201, 304 or 316 stainless steel, with wall thickness from 1 mm to 6 mm and diameters from 19 mm to 3000 mm. The disc is formed into a deep curve that reflects the sky, landscape or viewer into a compressed, distorted image. Because the surface is mirror polished, the reflection is clear and uniform, with no visible distortion at the edge. The disc is designed to be mounted on a wall or stand, so the viewer stands in front and becomes part of the artwork. The same fabrication process used for hollow balls is applied here, so the disc is light enough for two people to handle and install without lifting equipment.
Key Benefits
- Deep concave shape creates a dynamic, shifting reflection that changes with the viewer's position
- Mirror polish ensures a clear, uniform reflection without distortion at the edge
- Wall thickness from 1 mm to 6 mm allows weight and rigidity to match the installation site
- Diameters from 19 mm to 3000 mm are made on the same tooling, so a series of discs match exactly
- Mounted on a wooden stand or wall bracket so no site fabrication is needed
- AISI 201, 304 or 316 steel gives a choice of cost and corrosion resistance
Problems It Solves
- Flat mirrors lack depth and fail to engage the viewer in a dynamic way
- Painted or coated mirrors yellow or chip over time, especially outdoors
- Buying concave mirrors from multiple suppliers results in inconsistent polish and reflection
- Site drilling or mounting a finished mirror disc scratches the surface and ruins the finish
- Large concave discs become too heavy to handle safely without lifting equipment
- No standard size range means each disc must be custom ordered, increasing lead time
Application Scenarios
Interior wall installations in hotel lobbies, art galleries and private homes where the viewer becomes part of the artwork
Outdoor wall-mounted mirrors in gardens and public parks that reflect sky and trees into a compressed image
Architectural features in commercial buildings where the concave disc acts as a focal point and light reflector
Art installations where multiple concave discs are arranged in a sequence to create a shifting visual experience
Public art commissions where the disc is part of a larger sculpture or interactive installation
Film and VFX studios using the disc as a HDRI reference surface for lighting simulation
Who It Is For
- Interior designers specifying a reflective wall feature that draws the eye and creates depth
- Landscape architects placing a mirror disc in a garden to reflect sky and foliage

- Film and VFX studios needing a high-gloss, non-reflective surface for lighting reference
- Architects integrating a reflective disc into a building façade or interior feature
- Sculpture installers who need a ready-to-mount disc with a fixed stand or bracket
Technical Features
- Discs formed from two hemispheres pressed on a press, then seam welded and ground to an invisible joint
- AISI 201 for indoor or low-exposure use, AISI 304 for general outdoor, AISI 316 for coastal or chemical exposure
- Wall thickness selectable from 1 mm to 6 mm to balance cost, rigidity and weight

- Step 2Hemispheres stamped on a press to form the concave shape
- Step 3Halves fitted and seam welded into a closed disc
- Step 4Weld ground and blended until the joint no longer reads in reflection
- Step 5Holes drilled and threads tapped, or stand or bracket welded on
- Step 6Mirror polished through progressive grits to achieve a high-gloss finish
- Step 7Optional vacuum metallising, electroplating or candy colour spray applied
- Step 8Protective film applied, then placed on a wooden stand or packed in a wooden case
Quality Control and Use
Quality Control
- Seam checked in reflected light to ensure no flat spots or weld marks are visible
- Diameter and wall thickness verified against the order before polishing starts
- Thread holes gauged for pitch and depth after tapping
- Finished disc kept under protective film until packed
- Photographs of the finished disc sent for approval before the balance is invoiced
Use Guide
- Specify the diameter, wall thickness, material, finish and mounting type when requesting a quote
- Send the stand or bracket detail so the mounting is welded in the correct position
- Use AISI 316 if the disc is installed near the coast, in a pool area, or where de-icing salt is used
- Keep the protective film on until the disc is mounted and the site is clean
- Clean with a soft cloth and clean water; never use wire brushes or chloride-based cleaners
Compared With The Alternatives
| Alternative | How this product compares |
|---|---|
| Flat mirror panels | Creates a dynamic, shifting reflection that changes with the viewer's position, not a static image |
| Painted or coated mirrors | No yellowing or chipping over time, and the surface remains reflective without maintenance |
| Cast or solid metal discs | Much lighter for the same diameter, so easier to handle and install without lifting equipment |
| Acrylic or GRP concave mirrors | Real specular reflection and no surface degradation outdoors, but heavier and slower to produce |
