Sheet Metal Cabinets

Sheet Metal Cabinets Built Around Your Equipment

A custom cabinet follows your equipment layout, mounting points, cable routes, and service needs instead of forcing your design into a standard box.

Custom Sheet Metal Cabinets

Prototype, low-volume, and repeat production under one approved drawing revision

TZR manufactures cabinets for industrial, electrical, electronic, and commercial equipment. Each design can be adapted to the product, installation space, and operating environment.

Cabinet Formats

Wall-mounted boxes, freestanding cabinets, machine-side enclosures, equipment housings, and welded frames.

Typical Applications

Machine controls, factory automation, power systems, communications equipment, and laboratory devices.

Configurable Details

Define doors, mounting systems, ventilation, cable entry, access panels, lifting features, and external finish.

Is Your Cabinet Design Still Developing?

Send the current 2D or 3D files and tell TZR what the cabinet must protect, support, and contain.

Choose the Right Material and Finish

Material selection affects cabinet strength, weight, corrosion resistance, grounding, appearance, and total project cost.

Material and Finish Comparison
REAL MATERIAL & FINISH COMPARISON

Match the Material to the Environment

TZR commonly manufactures cabinets from carbon steel, stainless steel, galvanized steel, and aluminum.

When the specification is open, describe the operating environment and expected service life. We can compare practical manufacturing options.

Carbon Steel

A practical balance of strength and cost. It is often powder coated or painted.

Stainless Steel

Suitable for corrosive, washdown, hygienic, or appearance-sensitive use.

Galvanized Steel

Provides added corrosion protection for many indoor or sheltered applications.

Aluminum

Reduces weight and supports powder-coated, anodized, or brushed finishes.

Configure Doors, Panels, Hardware, and Access

Cabinet performance often depends on the details around doors, panels, installed hardware, cable entry, and future service access.

Plan Every Interface Before Production

TZR can plan cabinet access and installed features around your equipment layout, assembly process, and future service needs.

  • Doors and removable panels
  • Mounting plates and shelves
  • Hinges, handles, and locks
  • Cable entry and equipment cutouts
  • Grounding and inserted hardware
  • Clearance for coating and adjustment

Doors & Access

Hinges, handles, locks, removable covers, and access panels should support installation and later service.

Mounting & Hardware

Plan mounting plates, shelves, brackets, inserted nuts, studs, standoffs, rivets, fasteners, and grounding points.

Openings & Protection

Coordinate vents, louvers, cable entry, equipment cutouts, gasket channels, seams, and drainage paths.

Working Toward a NEMA or IP Target?

Share the required rating, environment, and validation responsibility. Door compression, gaskets, seams, openings, drainage, and installed hardware all affect final protection.

Review Manufacturing Risk Before Production

A cabinet can look complete in CAD but still create problems during bending, welding, finishing, assembly, or inspection.

DFM Review Focus

TZR reviews the cabinet as one connected manufacturing and assembly process, not as separate flat panels.

  • Short flanges and holes near bends
  • Inaccessible welds and distortion risk
  • Hardware clearance and panel alignment
  • Coating buildup and masked surfaces
  • Trapped liquid and drainage paths
  • Assembly sequence and inspection access

Bending & Geometry

Check material, thickness, bend geometry, bend reliefs, hole position, short flanges, and flatness risk.

Welding & Finish

Review weld access, distortion, coating buildup, masking, trapped liquids, and cosmetic surfaces.

Assembly & Inspection

Confirm hardware clearance, panel alignment, assembly sequence, door fit, and measurement access.

Controlled Revision. No Unapproved Changes.

TZR ties proposed adjustments to the controlled drawing revision, so engineering and purchasing can review function, cost, and manufacturability before metal is cut.

Coordinate Fabrication, Finishing, and Assembly

Connected manufacturing steps reduce handoff errors and help protect critical features from cutting through final packaging.

Coordinate Fabrication Flow
ONE CONTROLLED PRODUCTION FLOW

Coordinate Every Operation

TZR plans the manufacturing route around cabinet geometry, material, order volume, finish, hardware, and appearance requirements.

  • Flexible cutting and punching routes
  • Bending and welding sequence control
  • Protected threads and grounding areas
  • Finish masking and cosmetic-face care
  • Hardware installation and final packaging
PROCESS 01

Cut & Punch

Profiles, holes, knockouts, and formed features.

PROCESS 02

Bend

Cabinet panels formed to the approved geometry.

PROCESS 03

Weld

Joint choice matched to material and distortion risk.

PROCESS 04

Finish

Masking protects threads, contacts, and mating faces.

PROCESS 05

Assemble

Hardware, fit checks, and project packaging.

One Supplier. Fewer Production Handoffs.

Send the drawing revision, BOM, finish, and assembly scope so TZR can plan a connected route for the complete cabinet.

Control Fit, Appearance, and Repeatability

Cabinet quality includes door alignment, panel flatness, hole position, installed hardware, coating appearance, and final assembly fit.

Inspection Beyond Overall Size

TZR checks first articles, in-process features, surface requirements, and finished assemblies against the approved drawing and inspection plan.

  • Door gaps, alignment, and movement
  • Panel flatness and critical hole position
  • Weld condition and installed hardware
  • Coating texture and cosmetic surfaces
  • Assembly fit and protected interfaces
  • Packaging checks for finished cabinets

Dimensions & Fit

Measure critical dimensions, mating interfaces, hole positions, flatness, door alignment, and assembly fit.

Surface & Hardware

Check weld condition, coating appearance, cosmetic faces, locks, hinges, fasteners, and grounding points.

Records & Repeat Orders

Plan certificates, dimensional reports, finish records, traceability, fixtures, and packaging checks before quotation.

Define Acceptance Requirements Before Quotation.

Mark critical dimensions, cosmetic surfaces, mating interfaces, reports, traceability, and special packaging requirements in the RFQ.

Plan Prototypes, Cost, and Repeat Production

A prototype helps verify cabinet function and appearance, while complete program data supports realistic cost, lead-time, and capacity planning.

Prototype and Repeat Production
PROTOTYPE & REPEAT UNITS

Verify the First Units

Use prototypes to check the cabinet in the real equipment and installation context before approving repeat production.

  • Component fit and mounting points
  • Door movement and service access
  • Cable routing and heat management
  • Assembly time and hardware access
  • Finish, appearance, and packaging

Geometry & Size

Cabinet dimensions, bend count, welding content, access, and critical tolerances shape the manufacturing route.

Material & Finish

Material grade, thickness, coating, masking, texture, color, and cosmetic limits affect cost and schedule.

Volume & Hardware

Prototype quantity, order size, annual usage, purchased hardware, and assembly scope guide production planning.

Inspection & Packaging

Reports, traceability, special checks, protection, and shipping requirements should be defined before quotation.

Plan the Complete Program, Not Just the First Order.

Share prototype quantity, first-order quantity, annual usage, and expected volume changes so TZR can review fixtures, material purchasing, packaging, and capacity.
