Workshop

Inside the Factory

Every photograph below comes from our own production and shipping, and each one carries the note that explains what it shows.

Batch of mirror polished hollow steel balls waiting for inspection
Hollow balls in mixed diameters after polishing. Sizes across one order are produced together so a group reads as one composition on site.
Large mirror polished sphere with the reflection running unbroken across the surface
A finished sphere with the weld seams ground back and re-polished. A straight line reflected across the surface does not break in two, which is the test we apply before a piece is packed.
900 mm mirror polished stainless steel dome hemisphere
A 900 mm dome from the hemisphere line. Welded assemblies run to Φ3500 mm and stamped hemispheres from Φ20 mm, both with invisible seams.
Forming and finishing craft detail on a stainless steel sphere
Panel forming and seam grinding is where most of the labour sits. There is no standard die, so every diameter starts from a new panel development.
Mirror polished stainless steel sculpture in the workshop
Sculpture work developed with an artist or a studio. Our drawing team calculates the panels and our own artist team works alongside the client design.
Crated pieces prepared for international freight
Crating is designed around the finished dimensions and the freight route. Customs clearance paperwork is handled by the carrier and we assist where extra documentation is needed.

Quality Control

The Inspection Standard We Apply

1

Surface Uniformity

A polished surface is judged on whether reflected light is even across the whole ball rather than dark in low lying areas, whether the reflected object stays sharp, and whether it distorts.

2

Weld Seam Treatment

The weld line is where two panels meet and is the hardest area to finish. If it is not treated correctly the piece reads as a divided mirror and a straight reflected line breaks into two parts, so seams are ground and re-polished until the reflection runs through unbroken.

3

Material Selection

304 is used for indoor work. For coastal cities and acid rain regions 316 is specified because of its higher corrosion resistance, and we recommend 316 for outdoor sculpture generally. We do not recommend 201 for sculpture work.

Shipping and After Sales

How the Work Reaches You

By Express, Door to Door

Samples and small orders by DHL, UPS, FedEx or Aramex, usually 5 to 8 days, or China EMS at 10 to 16 days depending on country.

By Air, Door to Airport

Medium and urgent orders by bulk air shipment, usually around 5 days to your local airport, collected by your forwarder.

By Sea, Warehouse to Seaport

Larger orders by sea, usually 15 to 45 days to your local customs, with clearance handled by the carrier.

Delivery times are the ranges we quote against. Remote addresses attract an additional remote area charge from the express company.

FAQ

Trust Center FAQ

Do you hold ISO or CE certification?

We do not publish certification claims on this site. What we do publish is the inspection standard we apply to every polished surface, the exact size and thickness ranges we can produce, and the projects we have delivered with their locations and specifications. If your project requires specific documentation, ask us before ordering and we will tell you what we can provide.

How do you check a polished surface?

Three criteria: whether the surface is smooth with uniform reflection, whether the reflected object stays clear and visible, and whether the reflected object is deformed. The weld line is checked separately, because a badly finished seam splits a straight reflected line into two parts.

Which countries have you shipped to?

The projects on this site were delivered to the United States, United Kingdom, Ireland, France, Canada, Australia, Norway, Estonia, Taiwan, Japan and within China.

Can I see a piece before it ships?

Yes. Photographs of the finished piece are sent before crating so the surface and the mounting detail can be approved.
