Custom stainless steel fabrication

Precision Stainless Steel Enclosure Fabrication

Enclosuremfg fabricates high-specification enclosures from 304 and 316L austenitic stainless steel for demanding chemical, marine, and sterile pharmaceutical environments.

Dedicated processing, carefully controlled welding, and post-fabrication pickling and passivation help protect corrosion resistance and preserve the steel’s lasting metallic finish.

Built for exposure

Material integrity for demanding environments

From harsh chemical processing to salt-laden marine conditions, enclosure performance starts with suitable material, clean processing, and a finish that supports corrosion resistance.

Our dedicated stainless steel zone helps prevent cross-contamination from carbon steel particulates—protecting the passive oxide layer and the enclosure’s long-term durability.

Process control

Dedicated stainless steel manufacturing protocols

Each stage is considered to limit contamination, manage heat, and restore the surface after fabrication.

01 / Clean tooling

Non-ferrous contact

Stainless-compatible abrasive discs and clamping fixtures help keep carbon steel contamination away from the workpiece.

02 / Controlled welds

TIG and cold-welding techniques

Welding methods are selected to limit heat-affected zones and support seam integrity and panel geometry.

03 / Surface restoration

Precision weld cleanup, pickling, and passivation

Weld slag and heat tint are carefully removed before industrial acid pickling and passivation. This finishing sequence restores corrosion resistance and helps the enclosure retain a clean, lasting metallic appearance.

In-house production

Advanced fabrication capabilities

An integrated production line supports end-to-end project control, from engineering and cutting through finishing and inspection.

QA/QC specialists

Fiber laser cutting

12kW and 6kW centers process stainless sheets up to 25mm thick, producing burr-free edges and reducing secondary grinding.

Multi-axis CNC bending

Five CNC press brakes, including OG200 models, form complex geometries and large-format panels with precise bend allowances.

Surface conditioning

Integrated buffing workstations produce consistent #4 brushed or satin finishes with a uniform appearance.

Large-format finishing

An in-house 2500×6000 mm automated powder coating line accommodates oversized cabinets and equipment frames, avoiding third-party logistics.

Engineering partnership

DFM support, from model to production

Our stainless steel Design for Manufacturing review addresses material behavior and assembly details before production begins.

  • Thermal distortion control

    Strategic weld placement helps maintain the flatness of large panels.

  • Hardware integration

    Automated clinching installs PEM nuts and standoffs without compromising the enclosure’s ingress protection rating.

  • Structural detailing

    3D CAD modeling and unfolding improve material yield and identify assembly interference before fabrication.

Quality assurance

Verification at every stage

  1. 01

    Incoming material verification

    Material certificates and chemical composition checks.

  2. 02

    In-process inspection

    Stage checks during laser cutting, bending, and welding.

  3. 03

    First-article inspection

    Validation against 3D models and GD&T specifications before production runs.

  4. 04

    Final QA

    100% inspection of dimensions, weld penetration, and surface finish consistency.

Typical applications

Enclosures for critical operating conditions

Choose materials and fabrication details around your operating environment, from corrosive exposure to hygiene requirements and outdoor service.

Chemical & petrochemical

Corrosion-resistant control panels and junction boxes.

Marine & offshore

Salt-spray resistant housings for navigation and communication equipment.

Pharmaceutical & food processing

Hygienic, easy-to-clean enclosures designed to avoid bacteria-trapping crevices.

Energy infrastructure

BESS and power distribution cabinets built for long-term outdoor stability.

Flexible production

Prototypes through recurring supply

Our high-mix, low-to-medium volume model typically supports batches of 10 to 500 units. Keeping processes in-house—from laser cutting to powder coating—helps reduce multi-vendor delays and maintain control of delivery schedules and manufacturing accuracy for prototypes and recurring annual supply contracts.
