02 / Technical Capabilities
Mechanical Features for NEMA & UL Programs
These are common customer targets, not DRAmetal product ratings. The OEM, panel builder or test body owns final validation, marking and listing.
| Customer Rating Targets | NEMA 1, 3R, 4, 4X or 12 as defined by the OEM drawing and validation plan |
|---|---|
| Standards | UL 50 / UL 50E / UL 508A-related mechanical details only when specified by the OEM |
| Materials | Carbon steel, 304 / 316 stainless steel, aluminum |
| Gauge | Custom — typically 14–11 ga to application |
| Finish | ANSI 61 gray powder coat (standard); #4 brushed for stainless 4X |
| Sealing | Closed-cell gasket and compression details to the released drawing |
| Grounding | Grounding studs on body and door as defined by the OEM or panel builder |
| Doors & Latching | Single / double, hinged, lockable; multi-point latching |
| Back Panels | Powder-coated white steel sub-panels, sized to opening |
| Customization | Non-standard sizes, cutouts, knockouts, glands, HVAC openings |
03 / Manufacturing Process
From Sheet to Finished Enclosure
Our process delivers enclosure metalwork to the released drawing. Final environmental rating and system suitability require OEM or laboratory validation.
01
Laser Cutting
Precision cutting of body, door, and back-panel blanks, plus cutouts, knockouts, and mounting holes to your layout.
02
Bending & Forming
CNC press-brake bending of the enclosure body and door to precise dimensions and clean, consistent corners.
03
Welding & Seams
Welded seams, leg kits and reinforcements made to drawing-defined sealing and structural details for the customer's target environment.
04
Hardware Insertion
Grounding studs, PEM fasteners, hinges, latches, and collar studs installed for door, panel, and mounting.
05
Powder Coating
Surface prep and ANSI 61 gray powder coat (or your color); brushed #4 finish for stainless 4X enclosures.
06
Gasket & Assembly
Gasket application, door and hardware assembly, back panel fit, and final QC against rating and dimensions.
04 / Material Options
The Right Material for the Environment
Material choice drives both cost and corrosion resistance. Here's how the three families compare for electrical enclosures.
Carbon Steel
The cost-effective standard for indoor Type 1/12 applications. Powder coating provides an attractive finish and basic protection.
- Corrosion Basic (coated)
- Cost Lowest
- Best for Indoor, controlled environments
304 / 316 Stainless
Excellent corrosion resistance for harsh, washdown, or outdoor environments. 316 for chloride/coastal exposure; 304 for general corrosion.
- Corrosion Excellent
- Finish #4 brushed (4X)
- Best for Washdown, outdoor, NEMA 4X
Aluminum
Lightweight with natural corrosion resistance. Suitable where weight reduction matters or specific grounding requirements exist.
- Corrosion Good (natural)
- Weight Lightest
- Best for Weight-sensitive, outdoor

05 / Why It Matters
The Enclosure Protects Equipment — and People
An electrical enclosure isn't just a box. It protects equipment from the environment, protects operators from electrical hazards, and is often what an inspector signs off on before a system can be energized.
Rating Gates Approval
For control panels, the enclosure's NEMA/UL rating is what the inspection authority checks. The right rating, gasket, and grounding are what let a system pass inspection and energize.
Environment Drives Material
Indoor, washdown, coastal, or outdoor — each demands a different material and rating. Material, pretreatment and finish must be matched to the environment. Service life remains a buyer-defined target validated by the OEM or responsible test party.
Fit Saves Field Time
Correct cutouts, back-panel layout, and mounting provisions mean the panel builder drops components straight in — no field rework, no delays.
Grounding Is Safety
Grounding studs on body and door aren't optional on rated enclosures — they're a core operator-safety requirement we build in to spec.

09 / FAQ
Electrical Enclosure FAQ
Can you support NEMA rating targets?
We can fabricate gasket, grounding, seam and finish details from an OEM drawing targeting NEMA 1, 3R, 4, 4X or 12. DRAmetal does not assign the final rating; the OEM or test body validates it.
Are your enclosures UL 508A compatible?
We fabricate customer-released mechanical details used in UL-related panel programs. UL certification documentation is available on request for applicable products and components; confirm the model and listing scope for your project. The panel builder, OEM and NRTL retain responsibility for final panel testing and listing.
Which material should I choose?
Carbon steel for indoor Type 1/12; 304 stainless for general corrosion/washdown; 316 stainless for coastal/chloride or aggressive environments; aluminum where weight matters. We'll recommend based on your environment and budget.
Can you cut custom holes and knockouts?
Yes — we laser-cut cutouts, knockouts, gland holes, HVAC openings, and any custom features to your component and cable layout, so the panel drops in without field modification.
Do you provide back panels and mounting hardware?
Yes — powder-coated steel back/sub-panels sized to the opening, plus grounding studs, hinges, latches, and leg kits as needed. Tell us your layout and we build it complete.
What's your minimum order quantity?
We handle everything from prototype quantities to high-volume production runs. Send us your requirements and we'll confirm MOQ and pricing for your specific enclosure.
