01 / What We Fabricate
The Cabinet — Safe Housing for Power Distribution
A power distribution cabinet houses and isolates the switchgear, busbars, and breakers that branch incoming power to many loads. We fabricate the sheet metal cabinet — the safe, compartmentalized structure around your electricals.
Busbar Chamber
A dedicated busbar compartment that isolates the bus from the rest of the cabinet, with provisions for busbar supports and the clearances safe distribution requires.
Dead-Front & Doors
Dead-front panels that prevent contact with live parts, plus hinged doors and removable panels for safe access to breakers and terminals during service.
Compartments & Cable Entries
Internal compartmentalization (bus, breaker, cable zones), mounting plates for equipment, and sealed cable/conduit entries top or bottom.
Our scope: the sheet metal cabinet
We fabricate the cabinet structure — frame, body, busbar chamber, dead-front panels, doors, compartments, mounting plates, and cable entries — laser-cut, formed, welded, and finished, ready for equipment integration. Bought-out components such as transformers, circuit breakers and switchgear, busbars (copper/aluminum conductors), PDU modules, protective relays and monitoring, and all electrical wiring are integrated by you or your panel builder. We build the cabinet with compartments and provisions sized to your equipment.
02 / Cabinet Types
Cabinets for Every Distribution Need
We fabricate the cabinet structure for the full range of power distribution applications, to your equipment and design.

Switchgear Switchgear Enclosures
Enclosures for low- and medium-voltage switchgear — compartmentalized, dead-front structures housing breakers, switches, and protective equipment.
- Use LV/MV switchgear
- Build Compartmentalized
- Safety Dead-front
MCC MCC Enclosures
Motor control center cabinet sections with power bus provisions and plug-in module compartments — for industrial motor control and distribution.

- Feature Plug-in modules
- Form Vertical sections
03 / Technical Capabilities
Safe, Compartmentalized, and Standards-Aware
A power distribution cabinet has to protect people from live parts, isolate the busbar, dissipate heat, and meet standards. Here's what we fabricate to.
| Materials | Cold-rolled steel (ASTM A366/A611), galvanized steel, stainless, aluminum |
|---|---|
| Construction | Floor-mounted vertical cabinet sections; welded/bolted frame with mounting plates |
| Dead-Front Safety | Dead-front panels preventing contact with live parts during operation |
| Busbar Chamber | Isolated busbar compartment with support provisions and required clearances |
| Compartmentalization | Separated bus, breaker, and cable zones for safety and serviceability |
| Standards Awareness | Built to support IEC 61439 / NEMA enclosure and IP-rated requirements |
| EMI / Bonding | Metal construction meeting electrical bonding and EMI-shielding requirements |
| Access & Cable | Hinged doors, removable panels, top/bottom cable and conduit entries |
| Finishing | Powder coat (RAL), galvanized; ventilation provisions for heat dissipation |
We fabricate the cabinet structure to your equipment and standards. Transformers, breakers, switchgear, busbars, PDU modules, relays, monitoring, and wiring are integrated by you or your panel builder.
04 / Manufacturing Process
From Sheet to Distribution Cabinet
A distribution cabinet has to be safe, accurate, and ready for equipment. Our process delivers a compartmentalized cabinet built to your layout and standards.
01
DFM & Layout
Review your equipment, busbar, and compartment layout — confirm material, standards (IEC 61439/NEMA/IP), mounting plates, and cable entry plan.
02
Laser Cutting
Fiber laser cutting of frame, panels, mounting plates, and compartment dividers — with breaker cutouts, ventilation, and cable openings to precise position.
03
Forming
CNC press-brake forming of cabinet sections and panels — accurate bends for a rigid, true cabinet that assembles cleanly with proper clearances.
04
Welding & Assembly
Welding the frame, fitting dead-front panels, compartment dividers, busbar-support provisions, doors, and mounting plates for the electricals.
05
Finishing
Powder coat or galvanized finish, with ventilation provisions — corrosion protection and heat dissipation for a reliable, long-service cabinet.
06
Inspection
Dimensional inspection of compartments and mounting, clearance and fit verification, and finish inspection before delivery for your equipment integration.
05 / Why It Matters
What Makes a Distribution Cabinet Right
A distribution cabinet houses dangerous power and critical infrastructure. Four things separate a safe, reliable cabinet from a liability.
Personnel Safety
Dead-front construction prevents contact with live parts — the core safety principle of a distribution cabinet. The structure keeps operators safe even with the cabinet energized.
Busbar Isolation & Clearance
An isolated busbar chamber with correct clearances is essential for safe, compliant distribution. Precise fabrication maintains the clearances that prevent faults.
Heat Dissipation
High-current distribution generates heat. Ventilation provisions and proper cabinet design keep equipment within temperature limits for reliability and life.
Standards Compliance
Distribution equipment must meet IEC 61439, NEMA, and IP requirements. A cabinet built to support these — clearances, bonding, ingress protection — is the basis of a compliant system.

09 / FAQ
Power Distribution Cabinet FAQ
Do you supply complete distribution units or just the cabinet?
We fabricate the sheet metal cabinet structure — frame, body, busbar chamber, dead-front panels, doors, compartments, mounting plates, and cable entries. Transformers, circuit breakers and switchgear, busbars, PDU modules, protective relays, monitoring, and electrical wiring are integrated by you or your panel builder. We build the cabinet with compartments and provisions sized to your equipment.
What is dead-front construction?
Dead-front means the front of the cabinet (with or without a door) prevents the operator from contacting live electrical parts during normal operation. It's the core safety principle of a distribution cabinet — the structure keeps people safe even when the cabinet is energized.
Can you build to IEC 61439 or NEMA standards?
We fabricate the cabinet to support IEC 61439, NEMA and IP target requirements defined by the OEM — providing the clearances, compartmentalization, bonding, and ingress protection these standards require. Final assembled equipment certification is completed by you or your panel builder with the installed electricals.
Do you provide the busbar chamber and compartments?
Yes — we fabricate an isolated busbar chamber with support provisions and required clearances, plus compartmentalization separating bus, breaker, and cable zones for safety and serviceability. The busbars and breakers themselves are supplied and installed by you.
Can you match our equipment layout?
Yes — send us drawings or your equipment layout and we'll fabricate the cabinet to match, including compartment sizing, mounting plates, breaker cutouts, busbar-support provisions, ventilation, and cable entry positions.
What's your minimum order quantity?
We support everything from a single cabinet to production programs. Send us your equipment and design requirements and we'll confirm MOQ and pricing for your project.
