Custom enclosures for utility-scale and C&I battery energy storage systems, manufactured to customer-released mechanical drawings with thermal and deflagration interfaces defined by the integrator for the safety, durability and service-life target defined by the integrator.
Build-to-print mechanical scopes can cover container interfaces, outdoor cabinets and modular rack enclosures. The system integrator defines energy capacity, safety architecture and deployment approval.
Containerized Container-interface enclosures manufactured from released drawings. HVAC mounts, deflagration-vent interfaces, cable routes and rack structure are integrator-defined.
C&I Cabinet Commercial & industrial outdoor battery cabinets built around the integrator's released battery, thermal and safety layout. Weather and ingress requirements are project-defined and validated on the configured system by the responsible party.
Module Racks Internal structural racks and module enclosures for battery pack mounting. Engineered for seismic loads, busbar routing, liquid cooling integration, and serviceability.
Residential / BTM Wall-mount and floor-standing enclosures for residential and behind-the-meter storage. Sleek aesthetic, weatherproof, with thermal and safety features in a compact form factor.
These are review categories, not DRAmetal performance guarantees. The integrator, licensed engineer, test body and authority retain the approvals assigned to them.
| Parameter | Specification | Notes |
|---|---|---|
| Fire safety | Integrator-defined mechanical design | Deflagration and fire-barrier interfaces by drawing |
| Enclosure rating | Buyer-defined target | OEM or responsible test body validates the configured enclosure |
| Thermal management | Interfaces from released drawings | Integrator owns thermal performance and cell temperature validation |
| Operating temperature | Buyer-defined design range | Integrator validates the configured system over that range |
| Container format | Released container or custom interface | Shipping compatibility is confirmed by the responsible logistics and approval parties |
| Material | Galvanized / Corten / aluminum | Corrosion-rated per environment |
| Seismic rating | Licensed-engineer-defined | Site criteria and structural analysis govern |
| Wind load | Licensed-engineer-defined | Site wind study and structural analysis govern |
| Fire barrier | Integrator-defined barrier requirement | Rating and duration require evidence from the responsible test body |
| Corrosion protection | Buyer-defined environment and finish system | Responsible processor or laboratory supplies the agreed evidence |
| Cable management | Integrated trays, sealed entries | HV / LV separation |
| Approval boundary | System integrator / AHJ / test body | Final testing and approval not by DRAmetal |
| Production planning | Committed by project | After drawing, inspection and schedule review |
Eight precision steps from raw steel to fire-safety-ready, weatherproof, deployment-ready BESS enclosure.
Pre-production DFM including UL 9540A deflagration venting analysis, fire barrier design, thermal modeling, and structural load paths for the target deployment.
Material grade, source records, incoming checks and traceability are defined by RFQ. XRF or other PMI is included only when a responsible route is quoted.
The quotation confirms the cutting and punching route for wall panels, frames, vents, mounting patterns, cable entries and HVAC openings.
Press brake forming of panels and structural members. Container frame assembly to ISO corner-casting standards for intermodal handling and stacking.
Robotic MIG for structural frame and panel welds. Continuous welds on sealing-critical and fire-barrier joints. Distortion-controlled for panel flatness.
Galvanizing and coating follow the released environmental specification. Any ASTM B117 duration, method and acceptance criteria must be defined by RFQ.
HVAC mounting, fire-deflagration vents, cable glands, door gaskets, and battery rack mounting installed. NEMA 3R/4 sealing verified.
Ingress-related, structural or dimensional checks are performed only to the agreed method, acceptance criteria and record requirements. Final system safety validation remains with the integrator.
Material selection driven by environment, fire safety, and cost target — most BESS enclosures combine galvanized steel structure with corrosion-rated coatings.

Durable structural shells
Lightweight panels, C&I
Coastal / marine deployment
Barrier scope defined by the integrator
Specialty / hybrid configurations
A BESS enclosure failure can mean thermal runaway propagation, fire, and the loss of an entire storage asset. The system integrator owns fire-safety design, validation and approval; DRAmetal follows the released mechanical drawing and agreed inspection plan.
UL certification documentation is available on request for applicable products and components; confirm the model and listing scope for your project. Separately, UL 9540A evaluates a configured battery energy-storage system. DRAmetal fabricates released enclosure features; the integrator owns the test setup, report and approval.
Installation requirements are supplied by the integrator. DRAmetal can manufacture released spacing, separation and fire-barrier interfaces.
Outdoor weatherproof enclosure ratings — rain, sleet, ice, and (4) hose-directed water resistant for harsh deployment environments.
Safety requirements for secondary lithium cells and batteries for industrial applications — the international BESS safety benchmark.
Final NEMA/IP verification only to the integrator-defined method and responsible test party
Load cases, supports, lifting conditions and acceptance remain design-authority inputs
Temperature profile, configured specimen and external test provider are defined by RFQ
ASTM B117 work only when duration, specimen and acceptance criteria are quoted
IBC category, site inputs, analysis and validation remain with the responsible engineer
Manufacturing records only as listed in the accepted quotation and inspection plan

Poor insulation caused temperature differences, and the original enclosure did not meet the project's protection and fire-material requirements.
Results apply to the project configuration described on the linked page.
Read the Customer Project →Mechanical provisions for deflagration venting, fire barriers and module separation can be fabricated from the integrator's released design. The system owner retains testing, approval and safe-deployment responsibility.
From the enclosure to the cooling plates inside it — we manufacture the complete thermal management chain, proven across utility-scale enclosure and cold plate programs.
Complex BESS enclosure capacity can be constrained by material, welding and test-interface requirements. We quote the released mechanical scope and agreed records.
Galvanizing, coating and stainless options follow the released environmental and finish requirements. The integrator owns service-life validation and warranty.
Capacity is committed only after enclosure variants, tooling, finish, inspection, packout and delivery schedule have been reviewed and quoted.
Enclosure, battery racks, busbars, cooling plates — the complete BESS metal package under one roof, simplifying your supply chain.
Send your specifications — capacity, deployment environment, fire-safety requirements, thermal strategy. Our energy storage engineering team will review the submitted information and, where the scope is complete, provide a technical assessment, safety roadmap, and production timeline.
