01 / What We Fabricate
Order Custom 304 Stainless Steel Enclosures Built to Print
This product page is the quotation and manufacturing entry point for custom 304 stainless steel enclosures and drawing-defined 316L cabinets. Door gaps, hardware reinforcement, gland areas, gasket lands and surface condition are reviewed together; the companion design guide explains alloy selection rather than replacing the product RFQ.
Floor-Standing Cabinets
Single or multi-door stainless cabinets with base channels, removable panels and equipment mounting structures.
Washdown Housings
Slope, seam and hardware details fabricated to the OEM's released hygiene and cleaning requirements.
Junction and Terminal Boxes
Small-format housings with controlled cutouts, studs, hinges and cable-entry interfaces.
Our scope: the released mechanical enclosure
DRAmetal fabricates and inspects the released stainless enclosure. The OEM selects seals and components and owns final ingress, electrical, sanitation, corrosion and regulatory validation.
02 / Stainless Enclosure Types
Wall Boxes, Cabinets and Washdown Housings
All ratings and cleaning claims depend on the complete released design, seals, hardware and final validation.

03 / Technical Capabilities
Typical Stainless Enclosure Scope
| Materials | 304/304L and 316/316L stainless sheet and plate to released material specification |
|---|---|
| Fabrication | Laser cutting, punching, bending, drawing-defined welding and joining, grinding, hardware insertion and mechanical assembly |
| Surface options | 2B, brushed grain, bead blast, electropolish or passivation where drawing-defined and process-compatible |
| Critical controls | Door opening, gasket land, hinge and latch datums, gland plate, mounting pattern, flatness and grain direction |
| Documentation | Material identity, drawing revision, inspection report and finish records as specified |
| Supply boundary | Mechanical enclosure hardware; final IP/NEMA, electrical, hygiene and regulatory validation remains with the equipment OEM |
04 / Manufacturing Process
From Alloy Selection to Finished Enclosure
01
Environment Review
Confirm corrosion, cleaning, temperature and appearance requirements before alloy and finish release.
02
Interface Mapping
Define doors, seals, glands, equipment mounts, studs and installation datums.
03
DFM Review
Review grain direction, bend radii, weld access, distortion and finishing sequence.
04
Cut and Form
Protect material surfaces while cutting, forming and identifying parts.
05
Join and Finish
Control seam sequence, heat input, grinding and specified surface treatment.
06
Fit Inspection
Verify doors, hardware, gasket lands, mounting patterns and cosmetic zones.
05 / Why It Matters
Why Stainless Enclosures Fail Beyond Material Choice
Using 316L does not compensate for distorted doors, rough seal lands or contaminated finishing tools.
Cross-Contamination
Dedicated handling and finishing controls reduce embedded carbon-steel contamination.
Door Distortion
Weld sequence and reinforcement protect latch and gasket geometry.
Finish Consistency
Grain direction and cosmetic zones need drawing-level acceptance criteria.
Rating Interfaces
Cutouts, seals and hardware must be evaluated as a complete enclosure system.

The Customer Challenge
Uneven sealing faces compressed the gasket inconsistently and prevented the enclosure from reaching its intended protection level.

Why OEMs Use DRAmetal for Stainless Enclosures
01
Stainless workflow control
Protected material handling supports consistent corrosion-resistant surfaces.
02
Integrated fabrication
Cutting, forming, joining, finishing and assembly are coordinated in one release flow.
03
Functional inspection
Door, gasket, mounting and cable-entry interfaces drive the inspection plan.
04
Variant discipline
Alloy, finish, cutout and hardware variants remain tied to drawing revision.

09 / FAQ
Custom Stainless Steel Enclosures FAQ
Do you manufacture custom 304 stainless steel enclosures?
Yes. We manufacture build-to-print 304 and 304L wall boxes, cabinets, junction boxes and equipment housings.
How do I request a quote for a custom 304 stainless steel enclosure?
Send the released drawing or 3D model, 304 or 304L material requirement, enclosure dimensions, door and gasket details, finish, hardware, quantities and inspection criteria. We review the drawing-defined mechanical fabrication scope before quoting.
When should 316L be used instead of 304?
The OEM should select the alloy from the actual corrosion, chloride, cleaning and temperature exposure. We build to the released material specification.
Can you supply an IP65 or NEMA 4X enclosure?
We can fabricate the released seal-ready hardware, but the complete enclosure design, seals, penetrations and validation determine the final rating.
Can brushed grain direction be controlled?
Yes. Grain direction and cosmetic zones should be stated on the drawing so cutting, forming and finishing preserve the intended appearance.
What should a stainless enclosure RFQ include?
Send drawings, models, alloy and finish, cosmetic zones, seal and hardware details, CTQs, validation requirements, variants and quantities.
