Product Overview
Stamp pressed aluminium hemispheres are light and take powder coating well, which is why they end up in lampshade designs. There are no visible seams on the surface.
Hand assembled aluminium hemispheres remove the mould limit. Our technicians calculate the sheet development, workers bend the leaf shapes and weld a complete hemisphere, then grind off welds and burrs. Any size can be made from ∅200mm upward.
Key Benefits
- A6061 aluminum alloy Stamping Press Made.
- Ample wall thickness for welding and tapping Metric and Unified thread.
- MOQ:required-100PCS.
- Delivery Time:7days for Scheduled production.
Application Scenarios
- Lampshades and pendant lighting
- Suspended ceiling elements
- Exhibition sets
- Sculpture components
Who It Is For
- Lighting manufacturers
- Exhibition and stage builders
- Artists making suspended elements
- Interior fit-out contractors
Problems It Solves
- Ceiling and rigging load limits on hanging domes. Aluminium keeps the weight down.
- Coating adhesion on a formed dome. Powder coating suits the stamped surface.
- Large custom domes with no budget for tooling. Hand assembly has no mould limit above ∅200mm.
Technical Features
- Wall thickness available: 2mm
- Diameter: 102mm
- Surface finish options: Raw Finished
- Alloy: A6061 Aluminum Alloy
- Drilling and tapping in metric and unified threads on request
- Base plates, pedestal tubes and hanging fittings fabricated with the piece
- Sheet development calculated in house, so non-standard sizes are possible above ∅200mm

Materials
We form spheres and hemispheres in AISI 304, AISI 316 and AISI 316L stainless steel, Q235 carbon steel, H62 brass alloy and A6061 aluminium alloy. The alloy decides corrosion resistance, weight and how the surface takes a polish.
For this product the standard specification is A6061 Aluminum Alloy. Tell us the site conditions and we will confirm whether a different grade is worth the cost.
Manufacturing Process
Forming happens by stamping press, water pressuring, spinning or hand assembling. Two halves are joined at the equator, the weld is ground, and the surface is finished last, after any cutting or drilling has been done.
Quality Control
Incoming material
Alloy and sheet thickness are checked against the order before any blank is cut.
Forming check
Diameter and wall are measured after pressing, spinning or water pressuring.
Weld and grind
The equator weld is inspected, then welds and burrs are ground off before finishing.
Surface inspection
Every piece is inspected for scratches, dents and polish consistency under light.
Packing
Protective packing is built around the diameter and weight, and photographs are sent before dispatch.
Customisation Options
- Diameter and wall thickness to your drawing, with no mould limit above ∅200mm
- Metric and unified threaded holes, drilled apertures and perforated patterns
- Welded base tubes, base plates, internal ribs and pedestals
- Mirror, brushed, sandblasted, etched, electroplated, PVD colour or spray painted finishes
- Logos, lettering and world maps by sandblasting, etching, laser cutting or plasma cutting
- LED kits fitted inside the sphere
- Segmentation into quarters or eighths for sizes above container limits

Comparing forming routes rather than products? The process guide sets out size, thickness, seam and mould limit for each.
Use Guide
Confirm the diameter first
Diameter drives the forming route, the wall thickness, the price and the freight mode. Settle it before anything else.
Match the alloy to the site
304 inland, 316 near salt water or pools, Q235 where a rust patina is wanted, brass or aluminium where weight or colour matters.
Choose the finish last
Finishing always happens after forming, welding, cutting and grinding, so pattern edges stay clean.
Plan the fixing
Tell us whether the piece is bolted, threaded, welded to a base tube or suspended, and we build the fitting into the part.
Check the shipping limit
∅2200mm fits a container, ∅3500mm fits a flat rack, and larger spheres are segmented with bolted ribs.
