Custom Electrical Enclosures Melbourne: Cabinets, Control Panels & Switchgear Housings
How Melbourne electricians, OEMs and industrial buyers specify custom electrical enclosures — materials, apertures, cable entry, powder coating and what to send for a 24-hour quote from Moorabbin.

Custom electrical enclosures protect switchgear, PLCs, distribution boards, motor control centres and site equipment from dust, moisture and accidental contact. When a catalogue cabinet will not fit your layout, cutouts or finish, you need a custom fabricated electrical enclosure built to your drawing.
Orion Metal Industries fabricates electrical and control panel housings at 1A Bibby Ct, Moorabbin — south-east Melbourne — with laser cutting, press brake bending, welding, in-house powder coating and assembly under one roof.

What counts as a custom electrical enclosure?
Common types we fabricate for Melbourne commercial and industrial clients:
- Main switchboard and distribution enclosures
- PLC and automation control cabinets
- Motor control and VSD housings
- Site electrical kiosks and outdoor-rated cabinets
- Sub-board and metering enclosures
- Machine-mounted electrical boxes with custom gland plates
Each unit is made to your dimensions, wall thickness, door configuration and aperture layout — not adapted from a standard range.
When to specify custom instead of catalogue
Buyers search for custom electrical enclosures when:
- Cable entry and gland positions must match an existing slab, trench or cable ladder
- Door swing, hinges and lock type are defined by site access or security
- Ventilation or IP rating needs custom louvres, mesh or sealed construction
- Powder coat colour must match project branding (Dulux, Interpon or RAL)
- Internal mounting rails or DIN channels are at non-standard heights
For general kiosk and display housings, see our guide on custom sheet metal enclosures in Melbourne. For switchboards and PLC cabinets specifically, see custom electrical enclosures Melbourne.
Materials and thickness
Typical choices for electrical enclosures in Victoria:
| Application | Common material | Notes | |---|---|---| | Indoor control panels | Zincanneal or mild steel 1.6–2 mm | Powder coated finish | | General industrial | Mild steel 2–3 mm | Stiffness for larger doors | | Corrosive or wash-down areas | Stainless or galvanised | Specify grade with your drawing | | Lightweight OEM builds | Aluminium | Discuss bend radii at quote stage |
We review material, bend allowances and earthing/grounding requirements when you send drawings.
Fabrication process at our Moorabbin workshop
1. Drawing and brief
Send DXF, DWG, STEP or PDF with overall size, aperture list, door details, finish and quantity. We return a quote within 24 hours.
2. Laser cutting
Flat patterns and panels are cut on CNC fibre laser — fixing holes, vent patterns, lock cutouts and cable entry slots in the same program as the outer profile.

3. Press brake bending
Panels are formed on our press brake to create the body, flanges, door returns and gland plates. See our guide on sheet metal bending and pressing in Melbourne.
4. Welding, hardware and assembly
Seams and brackets are welded or fastened. Doors, hinges, locks, handles and internal mounting as specified.
5. Powder coating
Enclosures are powder coated in-house — gloss, satin or matt — to your colour reference.

6. Delivery
Dispatch across south-east Melbourne, greater Melbourne and Victoria.
What to include in your electrical enclosure brief
- External dimensions (H × W × D) and wall thickness
- Door size, hinge side, lock type and quantity of doors
- All cutouts with positions (meters, switches, fans, displays)
- Cable entry — bottom, top or side; gland plate layout if applicable
- Finish colour and indoor/outdoor exposure
- Quantity (prototype vs production) and required date
Compliance note: We fabricate to your drawings. Final compliance with AS/NZS wiring rules, IP ratings and sign-off remain the responsibility of your electrical designer or installer unless agreed otherwise in writing.
