Powder coating or painting finish

04 // Requirement

Fit check before final packing

Manufacturing Process

From Blank to Finished Component

The exact route depends on drawing, material and quantity, but the steps below show the manufacturing logic buyers can expect.

Step 01

Enclosure Drawing Review

Panel layout, bend direction, door clearance, hole pattern and coating requirements are reviewed.
