Large Stainless Steel Sculpture - Moon Gate
Large stainless steel Moon Gate sculpture, custom fabricated in Shenzhen, China. Designed for public and garden spaces, the gate stands 5 metres in diameter with a 2.1 metre high central opening. Constructed from AISI 201, 304 or 316 stainless steel, wall thickness ranges from 1 mm to 6 mm. The form is built from pressed and welded steel sections, finished in mirror, brushed or matt polish, and delivered with detailed shop drawings for site assembly. Suitable for parks, plazas, campuses, and private gardens where a large-scale, reflective architectural feature is needed.
Key Benefits
- Custom size available beyond standard tooling, so the gate can be scaled to site dimensions without compromise
- Hollow construction keeps the weight manageable for lifting and installation, even at 5 metre diameter
- Mirror polished finish holds clarity outdoors without fading or requiring repainting
- Wall thickness selectable from 1 mm to 6 mm to match structural needs without over-engineering
- Detailed shop drawings supplied so the gate can be assembled on site with no on-site welding or cutting
- Available in AISI 201, 304 or 316 stainless steel to suit climate exposure and budget
Problems It Solves
- Large steel gates become too heavy to install once they exceed 3 metres in diameter, requiring cranes and complex rigging
- Site welding on a large mirror polished surface damages the finish and requires costly rework
- Buying a gate from multiple suppliers results in mismatched finishes, welds and dimensions
- Lack of shop drawings means on-site assembly is slow, error-prone and requires skilled welders
- Cast or solid steel gates are too heavy for transport and lifting, even at moderate sizes
- Painted steel gates fade, chip and rust at the seams, requiring maintenance every few years

- Step 8Protective film applied, foam wrapped, and packed in a wooden or iron case
Quality Control and Use
Quality Control
- Welds inspected under reflected light to confirm no flat spots or visible seams
- Diameter and wall thickness verified against the order before finishing begins
- Thread holes checked for pitch and depth after tapping
- Final form checked against shop drawings for alignment and symmetry
- Photographs of the finished sculpture sent for approval before the balance is invoiced
- Packing inspected to ensure foam protection and case strength for sea freight
Use Guide
- Specify the exact diameter, wall thickness, finish and mounting method when requesting a quote
- Send the base or support detail so the mounting brackets are welded in the correct position
- Use 316 stainless steel if the gate is near salt water, pools or de-icing salt
- Keep the protective film on until the gate is bolted down and the site is clean
- Clean with water and a soft cloth; avoid wire brushes or chloride-based cleaners
- For a gate over 3 metres, plan for a two-point lift and padded cradle during installation
Compared With The Alternatives
| Alternative | How this product compares |
|---|---|
| Cast or solid steel gates | Much lighter and easier to transport and install, but not load bearing |
| Painted mild steel gates | No rust at seams and no repainting cycle, but higher initial cost |
| GRP or fibreglass gates | Real metal reflection and no yellowing outdoors, but slower to produce and less durable |
| Site-welded steel gates | No on-site welding means no finish damage and faster assembly, but requires pre-fabrication |
