Mirror Polished Metal Spheres and Sculpture Built to Your Drawing
We manufacture hollow stainless steel spheres, hemispheres, concave discs and custom metal sculpture for designers, artists, architects and landscape contractors. No standard die limits the size, and the weld seam does not show in the reflection.
What We Make

Manufacturing Process
How a Mirror Sphere Is Formed
Three routes, chosen by diameter, wall thickness and quantity.
Water Pressure Forming
Technicians calculate the exact developed size for each steel sheet, the sheet is bent into leaf shapes, welded into an approximate spherical cube and then expanded into a true sphere under water pressure. Weld seams are ground off and the surface is mirror polished. There is no standard die limiting the size, so any diameter can be built to a drawing.
Best for: Large and giant spheres, one-off commissions, sizes with no existing tooling
Mould Pressing
Sheet is deformed against a mould, two hemispheres are welded together, the weld seam is ground back and the ball is polished or brushed. Available from 5 mm to 500 mm diameter with 0.6 mm to 6 mm wall thickness, with drilling and tapping to your drawing and invisible weld seams.
Best for: Repeat batches of small and medium balls, gazing balls, drilled and tapped balls
Spinning
Two hemispheres are metal spun and then welded together, ground and polished. This is the route that produces the thickest wall sections we offer.
Best for: Heavy wall spheres and hemispheres, structural or high impact locations

FAQ
Frequently Asked Questions
The questions buyers ask before they send a drawing.
What exactly do you manufacture?
Hollow metal spheres, hemispheres and domes, mirror concave discs, chrome and grey VFX reference balls, sphere water features, corten steel sculpture and custom stainless steel sculpture. Diameters run from 19 mm to 5000 mm with 0.6 mm to 6 mm wall thickness.
Who do you normally work with?
Sculpture artists and studios, architects, real estate developers, landscape designers, interior designers, art consultants, garden retailers and film production teams.
Can you build from my own design?
Yes. Our factory keeps a 3D drawing design team and an in house artist team, and we work from a small sample, an idea, a 3D drawing or detailed photographs. OEM and ODM orders are welcome.
Which stainless steel grade do you recommend?
AISI 304 for indoor sculpture and AISI 316 or 316L outdoors, particularly in coastal cities and acid rain regions where corrosion resistance matters. We do not recommend 201 for sculpture.
How large a piece can you ship?
7 feet is the largest sphere diameter that ships by conventional freight. Larger sizes can be produced with special shipping arranged in advance.
How do I get a price?
Send the diameter, grade, finish, quantity and destination country on WhatsApp or by email. There is no form on this site.
