ATEX & Explosion-Proof Enclosure Manufacturing

At Weimiao, we specialize in the fabrication of explosion-proof and flameproof enclosures designed for use in Zone 1/2 and Class I Division 1 hazardous areas. Whether deployed on offshore oil rigs, inside chemical plants, or near gas transmission stations, our enclosures are built to withstand the harshest environments—while meeting the highest international safety standards.

We provide custom-engineered ATEX enclosures for clients across the oil & gas, chemical, power generation, and mining sectors, integrating both mechanical protection and electrical functionality under one roof. Every unit is fabricated with care, validated for durability, and prepared for certification-ready 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 manufactured for deployment in:

  • 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.

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 feature:

  • 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

 

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 not only ignition risks, but also extreme outdoor conditions, corrosion, temperature fluctuation, and frequent maintenance.

​

We offer material options including:

  • 316L stainless steel for high-corrosion areas (marine, chemical)

  • Powder-coated carbon steel for cost-effective durability

  • Cast or extruded aluminum for lightweight applications with thermal demands

 

Our enclosures meet or exceed:

  • IP66 / IP67 ingress protection (dust-tight and water-resistant)

  • UV-stable, corrosion-resistant finishes for onshore and offshore zones

 

Each cabinet is coated and sealed to resist chemicals, saltwater, oil mist, humidity, and abrasive particles—protecting sensitive electronics inside.

Electrical and Mechanical Integration

Unlike standard explosion-proof box suppliers, Weimiao delivers ready-to-integrate enclosure systems, tailored to your component layout, installation environment, and cable entry requirements.

​

We provide:

  • 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

 

Whether you’re building a control box for a Zone 1 junction point or a pump system interface in a remote LNG station, Weimiao ensures every detail is accounted for—mechanically secure, electrically compatible, and certification-ready.

Applications Across High-Risk Industries

Weimiao’s ATEX and explosion-proof enclosures are engineered for performance in the world’s most hazardous industrial environments. Built to prevent ignition and protect electrical systems in volatile zones, our enclosures are deployed across:

  • Oil and Gas Platforms (FPSO & Onshore Rigs): Enclosures for pump systems, monitoring panels, and power distribution cabinets on flammable gas sites.

  • Chemical Processing and Storage Plants: Control boxes and interface panels designed for corrosive atmospheres and explosion-prone operations.

  • Gas Regulating Stations & LNG Facilities: Flameproof control enclosures for valve automation, pressure monitoring, and field distribution in hazardous gas systems.

  • Battery Storage & Hydrogen Energy Systems: Spark-resistant housing solutions for energy storage, BESS, and hydrogen production control.

  • Dust-Risk Industries: Explosion-proof panels for environments with combustible dust such as flour mills, cement plants, metal powder facilities, and grain silos.

 

Wherever volatile gases, vapors, or dust are present, Weimiao provides safe, compliant, and long-lasting enclosure systems to keep personnel and infrastructure protected.

ATEX Project Support for Global Integrators

Delivering a certified enclosure is about more than manufacturing—it’s about engineering precision, documentation clarity, and project alignment. Weimiao works closely with global system integrators and OEM clients to provide smooth, end-to-end support for explosion-proof projects.

Drawing Review, Testing, and Certification Support

Before production begins, our team assists clients in reviewing technical drawings and enclosure schematics. We offer structural recommendations based on:

  • Component layout feasibility

  • Clearances for cable routing and airflow

  • Ingress protection and thermal design

 

When preparing for third-party certification or ATEX/IECEx audit, we ensure every enclosure meets your authority’s documentation and installation expectations.

​

Additionally, our factory follows an ISO 9001:2015 quality management system, offering full traceability, dimensional control, and pre-shipment validation—ideal for inspection or FAT (Factory Acceptance Testing).

Small Batch or Full Rollout Ready

Weimiao supports production at every stage, from early prototyping to full-scale project rollout:

  • Sample and small batch production for test installations or early site validation

  • Full batch manufacturing with consistent quality, wiring, and documentation

  • Protective export packaging with shock absorption, humidity control, and labeling

  • Barcode or RFID-ready labeling systems to support site logistics and asset tracking

 

With decades of experience shipping to Asia, the Middle East, Europe, and the Americas, we deliver not only products—but confidence.
