ATEX & Explosion-Proof Enclosures for Hazardous Areas
Weimiao manufactures custom ATEX & IECEx enclosures for Zone 1/2 and Class I Div 1 hazardous areas.
Project-based only — no single-unit or retail sales.
Built for oil & gas, chemical, power, and mining projects, each enclosure combines mechanical protection with certification-ready electrical integration.
Certified Solutions for Hazardous and Explosive Environments

In explosion-risk zones, every detail matters. Electrical panels must not only perform reliably but also contain or isolate any potential ignition sources. That’s why Weimiao offers explosion-proof enclosure solutions that align with the rigorous standards of:
-
ATEX (Europe)
-
IECEx (Global)
-
CNEX (China)
Our enclosures are specifically manufactured for deployment in high-risk environments, including:
-
Oil & gas production sites
-
Chemical processing and storage areas
-
FPSO platforms and offshore equipment rooms
-
Coal and metal mining facilities
-
Battery storage and hydrogen energy stations
Weimiao helps engineering teams, system integrators, and OEM clients reduce risk, shorten certification timelines, and comply with safety regulations—while maintaining flexibility for electrical layout and hardware mounting.
Weimiao is a direct manufacturer and fabricator of ATEX and explosion-proof enclosures. We do not act as a distributor or reseller of standard explosion-proof boxes.
Key Features of Our Explosion-Proof Enclosure Systems

Flameproof and Increased Safety Construction
Weimiao designs enclosure systems in accordance with:
-
Ex d (flameproof)
-
Ex e (increased safety)
-
Ex de (hybrid models)
Each enclosure is engineered to either contain internal explosions (Ex d) or prevent the formation of sparks and arcs (Ex e), depending on the classification and functional design.
Our flameproof cabinet designs provide robust protection and operational safety, featuring:
-
Thick-wall aluminum, carbon steel or stainless steel construction
-
Pressure relief or flamepath sealing
-
Gas-tight welded seams or heavy-duty bolted assemblies
-
Gasketed doors and interlock options for operator safety
To better understand the differences between Ex d, Ex e, Ex i, Ex p and other explosion protection methods, you may refer to our detailed technical guide:
A Complete Guide to Explosion-Proof Protection Types (Ex d, Ex e, Ex i, Ex p, Ex m Explained)
We follow strict tolerances for surface flatness, bolt torque, and cable entry shielding—ensuring every box is sealed, safe, and compliant for field use.
Material Selection and Protection Ratings
Explosion-proof enclosures must withstand ignition risks as well as extreme outdoor conditions, corrosion, temperature fluctuations, and frequent maintenance. Weimiao offers carefully selected materials to ensure safety, durability, and longevity in hazardous environments.
Our material options include:
• 316 / 316L stainless steel for highly corrosive environments, including offshore and chemical installations
• Powder-coated carbon steel for cost-effective durability
• Cast or extruded aluminum for lightweight applications with thermal demands
Protection Ratings
All Weimiao enclosures meet or exceed:
• IP66 / IP67 ingress protection (dust-tight and water-resistant)
• UV-stable, corrosion-resistant finishes suitable for both onshore and offshore zones
Each cabinet is fully coated and sealed to resist chemicals, saltwater, oil mist, humidity, and abrasive particles—safeguarding sensitive electronics inside.
Electrical and Mechanical Integration
Weimiao delivers fully ready-to-integrate explosion-proof enclosure systems, including PLC-based control panels and tailored electrical assemblies. Each enclosure is customized to match your component layout, installation environment, and cable entry requirements.
Our integration support includes:
-
BOM-based layout support for terminal blocks, switches, buttons, and display modules
-
Threaded or flanged cable entries, with cable glands pre-installed upon request
-
Breather valves, pressure relief devices, and EMC protection options
-
Integrated internal wiring trays, grounding points, and antistatic provisions
-
Optional LED lighting, inspection windows, or internal support frames
From Zone 1 junction points to remote LNG pump interfaces, every enclosure is engineered to be mechanically secure, electrically compatible, and certification-ready—minimizing installation risks and streamlining project compliance.
Applications Across High-Risk Industries
Weimiao’s ATEX and explosion-proof enclosures are designed to perform reliably in the world’s most hazardous industrial environments. They prevent ignition and protect electrical systems in volatile zones.
Our enclosures are deployed across a wide range of industries:
• Oil & Gas Platforms (FPSO & Onshore Rigs): Pump systems, monitoring panels, and PLC + VFD control cabinets for flammable gas sites.
• Chemical Processing & Storage Plants: Control boxes and interface panels for corrosive and explosion-prone environments.
• Gas Regulating Stations & LNG Facilities: Flameproof enclosures for valve automation, pressure monitoring, and field distribution.
• Battery Storage & Hydrogen Energy Systems: Spark-resistant housings for BESS, hydrogen production, and energy storage control.
• Dust-Risk Industries: Explosion-proof panels for combustible dust environments such as flour mills, cement plants, metal powder facilities, and grain silos.
In every application, Weimiao ensures safe, compliant, and durable enclosures to protect both personnel and infrastructure.
ATEX Project Support for Global Integrators
Delivering a certified enclosure is more than manufacturing—it requires precise engineering, clear documentation, and project alignment. Weimiao partners with global system integrators and OEM clients to provide end-to-end support for explosion-proof projects.
Drawing Review, Testing, and Certification Support
Before production, our team reviews technical drawings and enclosure schematics. We provide recommendations for:
• Component layout feasibility
• Cable routing and airflow clearances
• Ingress protection and thermal design
For ATEX or IECEx certification audits, we ensure each enclosure meets your authority’s documentation and installation requirements.
ISO 9001:2015 Factory Compliance
Our factory follows a strict ISO 9001:2015 quality management system, offering full traceability, dimensional control, and pre-shipment validation—ideal for inspection or Factory Acceptance Testing (FAT).
Small Batch or Full Rollout Ready
Weimiao supports production at every stage—from early prototyping to full-scale project rollout—aligned with EPC and system integrator project schedules.
Our manufacturing capabilities include:
• Sample and small-batch production for site testing or early validation
• Full batch manufacturing with consistent quality, wiring, and documentation control
• Protective export packaging with shock absorption, humidity control, and clear labeling
• Barcode- or RFID-ready identification to support site logistics and asset tracking
With extensive experience delivering ATEX and explosion-proof enclosures to Asia, the Middle East, Europe, and the Americas, we support global projects with reliable quality and predictable delivery.
