Custom Electrical Enclosure Fabrication — Precise & Fast
Industrial electrical enclosures from galvanized steel, stainless steel and mild steel. From small control cabinets to large distribution panels — right dimensions, right standards, on-time delivery.
What is an electrical enclosure?
An electrical enclosure is the frame and housing that protects internal electrical equipment — including circuit breakers, contactors, relays, PLCs and wiring. Enclosures must ensure dust/water protection (IP rating), electrical insulation and proper heat dissipation.
Industrial electrical enclosures are typically made from galvanized steel (SGCC) or stainless steel SUS 304, with 1.0–2.0mm thickness. Enclosure quality directly impacts the lifespan and safety of the electrical system.

Manufacturing Process
Custom electrical enclosure production process
From drawing to finished enclosure — an in-house, single-roof process with quality control at every step.
- 1 Send drawing / requirements
- 2 Quote & DFM review
- 3 Laser cutting + CNC bending
- 4 Frame welding & assembly
- 5 Powder coating
- 6 QC inspection & delivery
Recommended Materials
Galvanized steel SGCC is the most popular choice for enclosures due to good corrosion resistance and reasonable cost. Use stainless SUS 304 for humid environments or hygiene requirements.

Frequently Asked Questions
How much does electrical enclosure fabrication cost?
Price depends on size, material and quantity. Standard enclosure (600×400×200mm, SGCC 1.2mm) from $35–65 each. Send drawings for exact quote.
How long does it take to fabricate electrical enclosures?
5–10 business days for standard orders. Rush service available in 3 days. Large quantities (>50 units) need 15–20 days.
What are the steps to manufacture an electrical enclosure?
The process: send drawing → quote and DFM review → laser cutting → CNC bending → frame welding and assembly → powder coating → QC inspection and delivery. Everything is done in-house under one roof for tighter quality and schedule control.
What do I need to send to get a custom enclosure quote?
Send a drawing (PDF, DXF or STEP) or the dimensions, material, thickness, IP rating and quantity. No drawing yet? Send your requirements and our engineers will help with the design.
Should I choose IP54 or IP65 protection for my enclosure?
IP54 suits indoor, low dust/water environments. IP65 is for outdoor or dusty, humid conditions — requiring sealed gaskets and sealed welds. We fabricate enclosures to the exact IP rating you specify.
Should the enclosure use SGCC galvanized steel or 304 stainless?
Powder-coated SGCC galvanized steel suits indoor use at lower cost. SUS 304 stainless is for humid, chemical or outdoor environments thanks to higher corrosion resistance.
