Stainless Steel Hemisphere
Concave and Convex Mirror
Concave and convex mirror sculptures are formed from 304 stainless steel into hemispherical shapes and finished with mirror polish to reflect the sky, surroundings, and movement. Installed on walls or as freestanding features, they create dynamic visual effects that change with the viewer’s position and time of day. Each piece is built to the buyer’s drawing, allowing custom sizes and arrangements across a wall surface or in a space.

Key Benefits
- Mirror polished 304 stainless steel reflects sky, surroundings and movement, creating a dynamic visual effect that changes with viewer position
- Hemispherical form is forged from plate rather than cast, keeping weight low for wall mounting or freestanding placement
- Closed hemispherical shape has no sharp edges, suitable for public and interior spaces with high foot traffic
- Polished finish resists weathering and cleaning agents, maintaining appearance in outdoor or high-traffic indoor environments
- Custom sizes and arrangements built to the buyer’s drawing allow integration into a specific architectural or spatial layout
Application Scenarios
- Hotel lobbies and reception areas where a reflective surface adds depth and visual interest to a flat wall
- Shopping mall corridors and atriums where the mirror effect breaks up long sightlines and adds movement
- Public plaza walls and building facades where the sculpture interacts with passing people and changing light
- Interior design features in high-end residential spaces where a reflective object becomes a focal point
- Exhibition halls and art installations where the mirror’s distortion and reflection become part of the experience
Who It Is For
- Interior designers and FF&E buyers specifying reflective features for luxury hotels and commercial spaces
- Architects and building consultants integrating sculptural elements into wall surfaces and façades
- Property developers installing unique features in show units and common areas to enhance perceived value
- Art consultants and public art commissioners commissioning site-specific mirror sculptures
- Municipal and urban design teams placing reflective features in public plazas and pedestrian zones
Problems It Solves
- Standard flat mirrors or glass panels do not provide depth or visual interest in large-scale installations
- Cast or solid metal mirrors are heavier and require more complex mounting, increasing installation cost and risk
- Painted or coated metal surfaces degrade under cleaning or sunlight, requiring replacement or rework
- Catalogue-sized mirrors rarely fit a specific wall layout, leaving gaps or requiring awkward spacing
- Freight cost on solid or heavy mirror forms is high, especially for large or multiple pieces
Technical Features
- Body forged from 304 stainless steel plate into a hemispherical shape using hand forging and plate forming
- Welded closed form with seams dressed back before final mirror polishing
- Hollow construction reduces weight while maintaining structural integrity
- Mirror polish finish applied after welding and grinding to create a continuous reflective surface
- Fixing detail adapted to wall mounting, freestanding base, or floor anchoring based on site condition
Materials
- 304 stainless steel plate for the hemispherical body and fixing components
- Stainless steel welding consumables matched to the parent plate to maintain even polish across the weld
Quality Control
- Formed shape checked against the approved drawing before welding
- Weld seams inspected and dressed until they disappear under the polish
- Polished surface checked under light for grinding marks, orange peel or unevenness
- Protective film applied to every polished face before crating
Customization Options
- Any hemisphere size and any number of pieces arranged to your drawing
- Mirror polish, brushed satin, colour electroplating or baked lacquer finish per piece or per group
- Fixing detail adapted to wall, floor, or freestanding installation based on site conditions
- Sample piece produced for approval before full production begins
Use Guide
- Send the architectural drawing with positions, sizes and orientations marked for each piece
- Confirm whether the piece is wall-mounted, freestanding, or floor-fixed, as the fixing detail varies
- Leave the protective film in place until all surrounding construction is complete
- Clean with water and a soft cloth; avoid abrasive pads or chemical cleaners on the mirror surface
- Re-polish locally if a scratch occurs during site work rather than replacing the entire piece
Manufacturing Process
How This Piece Is Made
- Review of the architectural drawing or layout to confirm placement, size and orientation of each piece
- Calculation of plate forming data for each hemisphere before any steel is cut
- Hand forging of the steel plate into the hemispherical form
- Welding of the closed body and dressing back of the weld lines
- Grinding through successive grits followed by mirror polishing
- Welding of the fixing detail, application of protective film, and crating for export
Every stage happens in the same workshop in Pingshan, Shenzhen, which is why a set of pieces arrives matching.
Comparison
How It Compares With the Alternatives
Compared with Flat glass mirrorsGlass is fragile and cannot be shaped into a hemisphere without risk of breakage; stainless steel is durable and safe
Compared with Cast metal mirrorsCast pieces are heavier and more expensive; forged steel is lighter and more cost-effective at this scale
Compared with Painted or coated metalCoated surfaces chip and fade outdoors; mirror polish on stainless steel resists weather and cleaning
Compared with Resin or plastic mirrorsPlastic degrades under UV and cannot achieve a true mirror finish; stainless steel maintains reflectivity permanently

Concave and Convex Mirror Questions
What material are the mirrors made from?
They are forged from 304 stainless steel plate and mirror polished. This material holds a polish and resists weathering and cleaning agents.
Can you make them in the sizes on our drawing?
Yes. Our technicians calculate the forming data for each hemisphere, so the size and curvature follow your drawing exactly.
Can these be mounted on a wall?
Yes. Fixing details are welded to the back or base to suit wall mounting, freestanding, or floor anchoring based on site conditions.
What finishes are available besides mirror polish?
Brushed satin, colour electroplating and baked lacquer are available. Samples can be made for approval before production.
How are the pieces packed for export?
Polished faces are covered with protective film and the pieces are crated. We confirm the crating based on the destination port.
Can we see a sample before the full set is made?
Yes. One piece can be produced for approval before the full set goes into production.
How do we get a price?
Send the drawing or sketch with sizes and quantities by email or WhatsApp and we will quote against it.
