01 / What We Fabricate
Boxes and Trays Built for Handling, Fit and Finish
Box and tray programs often look simple on the drawing but fail in corners, lid clearance, hardware fit or packaging. We manage these details from flat pattern review through nested shipment.
Shallow Trays and Pans
Tray geometry is reviewed around drainage, flatness, corner sealing, nesting, handling and cleaning requirements.
Assembly-Ready Hardware
PEM nuts, standoffs, rivnuts, hinges, covers, labels and brackets can be integrated before packout.
Finish and Packaging Control
Galvanized, stainless, aluminum and powder coated boxes or trays are packed to protect lips, corners and cosmetic faces.
Our scope: formed boxes, trays and hardware-ready parts
We fabricate the blanks, bends, corner welds, hardware, finish and packout. Your team defines the final equipment assembly, cleaning requirements and any certification path.
02 / Box & Tray Types
Formed Sheet Metal Parts for OEM Production
We support box and tray programs where bend geometry, hardware location, finish and packout all affect final assembly.

04 / Manufacturing Process
From Flat Pattern to Nested Packout
01
DFM and Flat Pattern Review
Check bend relief, corner seams, lid clearance, hole-to-bend spacing, nesting and finish risk.
02
Cut, Punch and Form
Laser cut or punch blanks, then form lips, flanges, tabs, channels and stiffening beads.
03
Corner Welding and Hardware
Weld corners, install PEM hardware, add rivnuts, hinges, handles or brackets as required.
04
Deburring and Surface Prep
Remove sharp edges, prepare stainless or galvanized surfaces and mask critical areas before finish.
05
Finish and Inspection
Powder coat, passivate, plate or ship raw, then inspect fit, flatness, hole position and cosmetics.
06
Nested Packout
Pack boxes and trays by SKU, revision and finish with edge protection and nesting limits.
05 / Why It Matters
What Makes a Box or Tray Program Reliable
Boxes and trays are handled, nested, opened, cleaned and assembled. Small geometry decisions can create large production issues.
Bend Relief and Corners
Small boxes and trays often fail at corners when bend relief, weld access or drain paths are treated as afterthoughts.
Flatness and Nesting
Trays must stay flat enough for assembly while still nesting or stacking safely for shipment and line-side storage.
Hardware Fit
PEM hardware, standoffs, lids and rails need stable hole position after forming, coating and handling.
Clean Edges
Deburring and edge control matter on handled trays, electronics boxes and containment parts.

The Customer Challenge
Liquid collected in corners, and inaccessible weld crevices made the original box difficult to clean to the customer's requirements.

What to Define in a Box or Tray RFQ
Include these requirements with the controlled drawing, intended use and order quantity so the proposed process, inspection and packout can be compared on the same basis.
01
Corner Seams and Containment Checks
Mark open corners, welded seams, sealant locations and drain ports on the drawing. For a containment requirement, define the test medium, fill level, hold time, inspection stage and leakage acceptance criterion. Agree the test scope before quotation; a welded corner alone does not establish a liquid-tight result.
02
Lid and Hardware Fit
Include the mating lid drawing, hardware part numbers, thread sizes and assembly datums. Define clearances in the finished condition and identify gasket seats or latch engagement where needed. State whether lids must be interchangeable or supplied as matched sets, and agree the hardware-to-finish sequence.
03
Material and Finish Compatibility
Specify the substrate grade, thickness and finish system separately, along with cleaning or corrosion exposure. Mark cosmetic faces, masked threads, mating fits and any electrical bonding areas. Confirm treatment of cut edges and corner welds, plus an appearance sample or surface acceptance criteria suited to the chosen material.
04
Nesting and Packout Protection
State whether parts may nest, the allowed stack quantity, separation method and protected contact faces. Review lid lips, coating rub points and protruding hardware in the packed arrangement. Agree SKU/revision labels, handling limits and how parts will be separated without damage at unpacking.

09 / FAQ
Custom Sheet Metal Boxes and Trays FAQ
Can you make both boxes and trays in one product family?
Yes. Many OEM programs include related trays, open boxes, lidded boxes and slide-in assemblies. We manage them by SKU, revision, finish and packout.
Can you support stainless trays and galvanized boxes?
Yes. Stainless steel, galvanized steel, aluminum and powder coated carbon steel are common choices depending on corrosion, cleaning and cost requirements.
Can you add PEM hardware, lids and brackets?
Yes. We can install PEM nuts, standoffs, rivnuts, hinges, handles, covers, brackets and rails so parts arrive assembly-ready.
