Anish Kapoor Silver Large Mirror Polishing Concave Disc
Large mirror-polished concave stainless steel wall discs pressed from AISI 201, 304 or 316 sheet and formed into a deep curve. Wall thickness ranges from 1 mm to 6 mm and diameters from 19 mm to 3000 mm, so the same disc can serve as a reflective wall panel in a hotel lobby, a focal point in a public plaza, or a sculptural element in a private garden. The concave shape draws in the viewer and reflects the surroundings in a distorted, dynamic way, making each encounter unique and immersive.
Key Benefits
- Mirror polish creates a high-gloss surface with clear, uniform reflection that draws in the viewer and integrates them into the artwork
- Concave shape produces dynamic, non-static reflections that change with the viewer’s position and surroundings
- Hollow construction keeps large discs light enough for two people to handle and install without heavy lifting equipment
- Wall thickness selectable from 1 mm to 6 mm to match structural needs without over-specifying
- Discs are formed, welded, and polished before mounting so no on-site work is needed
- Available in AISI 201, 304 or 316 to suit indoor, coastal or high-exposure environments
Problems It Solves
- Flat mirrors or painted surfaces lack depth and do not change with the viewer’s movement
- On-site forming or polishing of a concave disc damages the mirror finish and creates imperfections
- Multiple suppliers for different sizes lead to inconsistent polish and reflection quality
- Lack of a fixed mounting point means the disc must be drilled and mounted on site, risking damage
Application Scenarios
Reflective wall panels in hotel lobbies, atriums and high-end retail spaces
Focal points in public plazas, parks and campus courtyards where viewer interaction is desired
Interior design features in private homes, galleries and corporate offices
Art installations where the viewer’s movement creates a shifting, evolving reflection
Complementary elements in larger sculpture groups where concave and convex forms contrast
Outdoor installations where the disc reflects sky, trees or architecture in a distorted, artistic way
Who It Is For
- Interior designers specifying reflective elements that engage the viewer in a space
- Public art commissioners seeking interactive, dynamic sculptures for urban environments
- Landscape architects integrating reflective art into garden and plaza designs
- Hotel and property developers wanting unique, high-impact interior features
- Sculpture installers needing pre-fabricated, ready-to-mount concave discs
- Film and VFX studios using the disc as a HDRI reference surface for lighting
Technical Features
- Single piece formed from a stamped hemisphere and shaped into a deep concave curve
- Seam welded and ground to an invisible joint, then mirror polished to a high-gloss finish
- AISI 201 for indoor use, AISI 304 for general outdoor use, AISI 316 for coastal or high-chemical exposure
- Wall thickness from 1 mm to 6 mm selected to match the load and support requirements

Quality Control and Use
Quality Control
- Seam inspected under reflected light to ensure no flat spots or visible welds
- Diameter and wall thickness verified against the order before polishing begins
- Mounting points checked for correct position and weld integrity
- Mirror finish evaluated under natural and artificial light for uniformity and clarity
- Photographs of the finished disc sent for approval before the balance is invoiced
- Protective film kept on until the disc is installed and the site is clean
Use Guide
- Specify the diameter, wall thickness, material and mounting type when requesting a quote
- Send the mounting detail so brackets or flanges are welded in the correct position
- Use 316 if the disc is near salt water, pools, or de-icing chemicals
- Keep the protective film on until the disc is mounted and the site is clean
- Clean with soft cloth and water only; never use wire brushes or chloride-based cleaners
Compared With The Alternatives
| Alternative | How this product compares |
|---|---|
| Flat mirror panels | Concave shape creates dynamic, shifting reflections that change with movement, while flat mirrors show a static image |
| Cast or solid discs | Hollow construction reduces weight significantly, making large discs easier to install without heavy plant |
| Painted or coated steel discs | Mirror polish maintains a durable, reflective surface without chipping or fading, but requires careful handling |
| Acrylic or GRP concave discs | Stainless steel offers real specular reflection and long-term durability, but is heavier and more expensive to produce |
