5Route steps
A sign post is primarily made by Powder Coating. Powder coating sprays charged dry powder onto a part, which is then baked so it melts and flows into a tough, even film. Below is the full route to make a sign post, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a sign post is made
The usual route, raw material to finished part. The amber step is where the sign post gets its basic shape.
Make the part
Form and finish-machine the sign post to size first.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Clean and mask
Clean the surface and mask the areas that must stay bare.
Powder Coating
Apply the powder coating to the sign post.
Tooling Low Tolerance adds 0.05 to 0.2mm Lead days
Post-finish
Seal, cure or re-grind any surface that changed dimension.
Inspection
Check coating thickness, hardness or adhesion.

Cost
What a sign post should cost
Durable decorative/protective finish on metal; priced by area and colour runs. Tougher than wet paint, needs line-of-sight.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a sign post at your volume, in your currency, are in the dossier.
