Material selection is critical for enclosure performance and service life.
Weimiao provides a wide range of industrial-grade materials, selected according to environmental and operational requirements:
-
Carbon steel with industrial powder coating
-
Stainless steel 304 for general industrial applications
-
Stainless steel 316 / 316L for corrosive and high-humidity environments
-
Optional materials available upon request for special applications
Learn more about different industrial enclosure types, stainless steel enclosure materials, and IP rated enclosure configurations for industrial applications.
316L stainless steel enclosures are frequently specified for chemical plants, coastal installations, water treatment facilities, and hygienic environments where corrosion resistance is essential.
Environmental Protection and Standards
Weimiao industrial enclosures are designed for real operating conditions, not just nominal ratings.
Typical protection levels include:
-
IP54 / IP65 / IP66 / IP67
-
Indoor and outdoor installations
-
Dust, moisture, and washdown environments
Thermal management, airflow design, and heat dissipation are carefully evaluated during the engineering phase to ensure stable operation of internal equipment.

What Makes Weimiao Industrial Enclosures Different
Not Standard Sheet Metal. Fully Engineered Enclosure Systems
Unlike off-the-shelf sheet metal boxes, Weimiao industrial enclosures are designed as part of the complete system.
Mechanical structure, electrical layout, ventilation, cable routing, and installation interface are all considered from the early engineering stage.
Our industrial enclosures are commonly integrated with PLC control panels, PLC + VFD integrated panels, and MCC systems for reliable industrial automation.
This system-oriented approach ensures reliability, serviceability, and long-term operational safety.
Designed for Global Projects and Export Requirements
Weimiao supports international EPC and OEM projects where consistency, documentation, and compliance are critical.
Our industrial enclosures are designed to meet:
-
IEC standards
-
Export and overseas installation requirements
-
Clear labeling and nameplate systems
-
Structured drawings and documentation packages
With experience supporting overseas installation teams, Weimiao ensures that enclosures arrive ready for efficient on-site integration.

Engineering, Manufacturing, and Quality Control
Design Based on Drawings and Project Requirements

Every Weimiao enclosure project starts with engineering input, not product selection.
Design is based on:
-
General arrangement (GA) drawings
-
Electrical layouts and equipment lists
-
Load and heat dissipation requirements
-
Installation and maintenance considerations
This ensures each enclosure is tailored to the actual system, not adapted after fabrication.
Manufacturing and Assembly in a Controlled Environment
All enclosures are manufactured under controlled production processes, including:
-
Precision fabrication and forming
-
Professional welding and surface finishing
-
Dimensional and structural quality control
-
Assembly readiness for electrical installation
Attention is paid to structural rigidity, door alignment, sealing integrity, and long-term durability.

Factory Acceptance Test (FAT) Support
Where required, Weimiao supports FAT and inspection processes, including:
-
Mechanical inspection
-
Fit and clearance verification
-
Interface checks with control panels and internal equipment
This reduces site risks and ensures smooth installation and commissioning.
In-House Air Leak Testing and Sealing Verification
To support IP-rated industrial enclosure projects, Weimiao provides in-house air leak testing and sealing verification for selected enclosure applications.
This testing capability helps evaluate enclosure sealing performance before delivery, especially for industrial enclosures used in:
• High-humidity environments
• Outdoor installations
• Washdown areas
• Offshore and marine applications
• Corrosion-resistant enclosure systems
Our engineering team can perform sealing verification during prototype evaluation or final inspection stages, depending on project requirements.
Typical evaluation items include:
• Door and gasket sealing integrity
• Leakage verification for enclosure structure
• Cable entry sealing performance
• Assembly and enclosure fit consistency
This capability supports improved enclosure reliability, reduced field installation risks, and more stable long-term environmental protection performance.
