Mating Geometry
Edges, tabs, return flanges, latch areas and screw patterns are controlled so covers land on the chassis without forcing.

01 / What We Fabricate
The Cover Structure That Protects the Equipment
Covers and shrouds define service access, airflow, operator safety and the visible face of the equipment. We fabricate the cover set around your drawing package so fit, finish and protection stay repeatable.
Vent and Access Features
Louvers, slots, perforations, service openings and cable cutouts are built for airflow, strength and clean edges.
Visible Surface Control
Powder coat, brushed stainless, plating and film-protected faces are handled as defined cosmetic surfaces.
Service Hardware
Captive fasteners, PEM hardware, hinges, handles and latch plates are planned around repeat service and assembly access.
Our scope: the fabricated cover and shroud set
We fabricate the cut, formed, louvered, welded, hardware-inserted and finished cover set. Your team integrates seals, labels, electronics and final equipment assemblies.
02 / Cover Types
Covers and Shrouds Built for Fit and Protection
Covers look simple until airflow, fastener access, bend distortion, finish quality and assembly clearance all have to line up. We build cover families as controlled production components.
Vented Vented Equipment Covers
Formed covers with slots, louvers, perforations and raised features for electronics, power supplies, drives and compact equipment.
- Features Louvers, slots, perforation

04 / Manufacturing Process
From Flat Blank to Finished Cover Family
01
Fit, Vent & Cosmetic Review
Confirm mating chassis dimensions, fastener access, airflow area, bend radii, visible surfaces and masking requirements before first article.
02
Cut, Punch & Form
Laser cut or punch blanks, form louvers and slots, deburr contact edges and bend cover flanges in a sequence that controls twist.
03
Hardware & Fit Check
Install captive hardware, verify cover alignment, check fastener clearance and inspect any functional vent or access features.
04
Finish & Scratch Protection
Apply final finish, protect visible surfaces with film or separators and pack covers by SKU for line-side installation.
05
Inspection
Check cover fit, louver quality, fastener access, surface criteria, coating thickness and edge safety.
06
Protected Packout
Pack covers by SKU and finish sensitivity with film, sleeves, separators or corner protection as needed.
05 / Why It Matters
What Makes a Cover Program Work
Cover quality affects fit, airflow, service safety and the customer's first visual impression of the finished equipment.
Fit to Chassis
Mounting holes, return flanges and latch zones need repeatable alignment after finishing.
Airflow Without Weakness
Slots, louvers and perforations need enough open area without making the face unstable.
Visible Finish
Cosmetic surfaces need defined inspection criteria, masking rules and careful handling through final packout.
Scratch-Free Delivery
Finished covers are vulnerable to shipping marks, so packaging has to match the finish and carton mix.

09 / FAQ
Custom Sheet Metal Cover FAQ
Can you make vented covers and louvered shrouds?
Yes. We fabricate covers with laser-cut slots, punched perforations, formed louvers and matched openings. We review airflow, edge strength and finish before production.
How do you protect cosmetic covers during shipment?
Visible covers can be packed with protective film, foam, paper separators or individual sleeves. We define the packout method during first article review.
Can covers be matched to an existing chassis?
Yes. Send the chassis drawing, cover drawing or mating dimensions. We can review clearance, fastener access and stack-up before releasing the cover to production.
