Mild Steel Electrical Enclosure Industrial Commercial VFD Control
Cabinet
Product Describe:
1. Indoor industrial control systems: Housing low-voltage
components like contactors, relays, or PLCs in dry workshops or
factories, where corrosion risks are minimal.
2. Building electrical distribution: Used as junction boxes or
meter cabinets in indoor settings (e.g., basements, utility rooms)
to protect wiring and electrical meters.
3. General-purpose storage: Enclosing non-critical equipment such
as small pumps, fans, or lighting controls in warehouses or
commercial facilities.
4. Low-humidity environments: Suitable for indoor telecom rooms or
office building weak current cabinets, where minimal exposure to
moisture or chemicals ensures durability.

|---|
| IP20 | Protects against ≥12.5mm solids/No water protection | Dry indoor environments (electrical rooms, server rooms) | Standard steel plate, no special sealing required |
| IP54 | Dustproof + Splash-proof | Industrial workshops (light dust/humidity) | Door gaps require sealing strips |
| IP55 | Dustproof + Low-pressure water jet protection | Outdoor uncovered areas | Full weld seams required, surface powder coating |
| IP65 | Complete dustproof + High-pressure water jet protection | Harsh environments (ports, mines, etc.) | Double sealing structure + Drainage design |
| IP66 | Complete dustproof + Powerful water jet protection | Ship decks, petrochemical plants | 304 stainless steel hinges + Pressure relief valve |
| IP67 | Complete dustproof + Temporary immersion protection (1m/30min) | Underground projects, flood control facilities | Fully welded enclosure + Waterproof cable glands |
Suggestion:
Clarify functional needs: Prioritize heat dissipation for
high-power equipment; enhance IP rating for outdoor use to resist dust and water.
Define dimensions: Size based on installation space and internal
components. Opt for compact wall-mounted designs for narrow areas or larger
floor-standing models for more elements, with extra space reserved
for future expansion.
Optimize structure: Ensure cabinet doors open to ≥90° for easy
maintenance. Add lifting holes or handles for handling; design suitable structures for side-by-side installation if needed.
Material details: Choose mild steel thickness (1.0–2.5mm) based on
load and vibration—thicker plates for heavy components or
high-vibration environments. Consider galvanizing to boost corrosion resistance.
Surface treatment: Use epoxy powder coating (80–100μm thick, baked
at 180–210°C) with non-glare textures (e.g., smooth/fine patterns).
EMC considerations: Adopt grounding, shielding, and filtering. Use
conductive gaskets for seams, shorten screw spacing, and add
shielding nets for vents/observation holes.
Internal layout: Separate high-voltage (contactors, relays) and
low-voltage (sensors, controllers) components to reduce
interference. Ensure safe distances for wiring and maintenance.
Accessories: Select locks, hinges, gaskets, and handles. Locks should offer security; gaskets improve protection against dust/moisture.
