Cangzhou Mengqi Hardware Products Co., Ltd. is one of the leading manufacturers and suppliers of control cabinet in China. Please feel free to buy cheap control cabinet made in China here from our factory. All customized products are with high quality and low price.
The control cabinet is a closed metal structure, made of cold-rolled steel plate/stainless steel through laser cutting, CNC bending, welding, and electrostatic powder coating. Internally, it integrates mounting plates, guide rails, beams, cable channels, etc., providing standardized installation space for circuit breakers, contactors, PLCs, frequency converters, instruments, etc., and possesses four core values: safety protection, electromagnetic shielding, heat dissipation and moisture protection, and convenient maintenance.
Control Cabinet Core Structure and Materials
1. Main Materials
Cold-rolled steel plate (SPCC): Preferred for general industrial applications, thickness 1.5–2.5mm, surface electrostatic powder coating (RAL7035/7032), IP30–IP54, high cost-effectiveness
Stainless steel (SUS304/316L): Suitable for humid, corrosive, and outdoor environments, IP54–IP65, rust-proof and corrosion-resistant, long service life
Aluminum alloy/Engineering plastics: Lightweight and insulating, suitable for small boxes/operating units
2. Structural Design
| Material Type | Core Parameters | Applicable Scenarios | Protection Rating | Core Advantages |
| Cold-rolled steel sheet (SPCC) | Thickness 1.5–2.5mm, surface electrostatic powder coating (RAL7035/7032) | General industrial indoor scenarios, general electrical control equipment | IP30–IP54 | First choice for industrial general use, robust and durable, excellent cost performance |
| Stainless steel (SUS304/316L) | SUS304 general corrosion resistant, SUS316L strong acid and alkali resistant | Humid, highly corrosive, harsh outdoor conditions | IP54–IP65 | Excellent rust resistance, acid and alkali resistance, anti-aging, long service life |
| Aluminum alloy/engineering plastic | Lightweight material, excellent insulation performance | Small control boxes, equipment operation boxes, lightweight insulation scenarios | IP30–IP54 | Lightweight, good insulation, suitable for simple electrical control boxes |
Control Cabinet Functions
Electrical Safety Protection: Isolates live parts, protects against electric shock, short circuit, overload, and leakage, ensuring personal and equipment safety.
Centralized Equipment Control: Integrates PLC, frequency converter, relays, etc., to achieve motor start/stop, speed regulation, interlocking, and sequential control.
Status Monitoring and Protection: Real-time monitoring of voltage, current, temperature, and energy consumption; automatic fault alarm/tripping to ensure continuous operation.
Optimized Wiring and Maintenance: Standardized wiring, separation of strong and weak current, reducing interference; modular design for easy maintenance and expansion.
Environmental Adaptability: Heat dissipation/dehumidification/dustproof design, suitable for industrial environments such as -20℃ to +55℃, humidity, dust, and vibration.
Control Cabinet Product Advantages:
Key Points for Control Cabinet Selection and Application Scenarios:
Environmental Adaptability: Standard selection: Cold-rolled steel plate IP54; Humid/corrosive selection: Stainless steel; Outdoor selection: IP65 + sunshade.
Size and Load Capacity: Select cabinet size and mounting plate thickness based on component quantity/weight, allowing 20% expansion space.
Protection Rating: Indoor IP30–IP54; Dust/Water Spray IP55–IP65; Explosion-proof environment requires Ex certification.
Cooling Design: Power consumption > 500W requires a fan; > 1500W requires air conditioning; enhanced cooling for high-temperature environments.
