For external or wet area applications, aluminium & mild steel substrates to be specified/ ordered as “Duplex plating”.  EG “Duplex Chrome”, “Duplex Nashira”, “Duplex Arcturus”

To maintain the integrity of finish, parts should not be cut or drilled after plating as this leaves the base metal exposed to environmental degradation and we will not warrant our finish under these circumstances.


Moveable parts – these will not plate successfully

It is not recommended to brass or copper-plate thick mild steel or tubular mild steel, we can substitute with tinted lacquers on nickel

Porous metal including;
Poor quality mild steel and aluminium
Cast Iron
Porous castings

Pinholes in welds will show up after plating, so ask your fabricator to dress the welds, and use TIG on mild steel and stainless

Braised brass joins can show up a different patina, however we can successfully plate over braises to ensure consistent finish

Items over 70kg

Please provide sketches for large folded panels which are close to our max capacities as these will need to be confirmed by technical manager for current flows, and handling

Deep recesses (more than 100mm)

Open frames are better suited to plating than close backed frames.

Items which do not drain – hollow tube frames must not have close welded sections, thus require mitre joins and/ or drainage holes

Items which do not submerge

Horizontal surfaces including benchtops and work surfaces

Items which create air-pockets

Items which cannot be completely submerged into tanks

Items with rubber, plastic, glue, lock-tite, bog or other non-metal fillers,

Magnetic parts – these affect the current flows required for electroplating

Gas struts and hinges with oil or gas

Used oil or petrol tanks

Sinks (or similar items with deep recesses)
