A fence post is primarily made by Roll Forming. Roll forming feeds strip through a train of rollers that progressively bend it into a constant open or closed profile along its length. Below is the full route to make a fence 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 fence post is made
The usual route, raw material to finished part. The amber step is where the fence post gets its basic shape.
Material
Select the sheet grade and gauge for the fence post.
Blanking
Cut the flat blank, by laser for low volume or a blanking die at scale.
Tooling Low (laser) to high (die) Tolerance ±0.05 to 0.3mm Lead days to weeks
Roll Forming
Form the blank into the fence post.
Tooling High (roll sets) Tolerance ±0.2 to 0.8mm Lead 8 to 16 weeks
Secondary features
Punch or drill the holes and cut-outs the part needs.
Tooling None Tolerance ±0.05 to 0.2mm Lead hours to days
Joining
Spot weld, fasten or bond into the assembly where the fence post is more than one piece.
Tooling Medium Tolerance joint Lead immediate
Finish
Deburr the edges and powder coat or plate for protection and colour.
Tooling Low Tolerance adds 0.05 to 0.2mm Lead days
Inspection
Check formed dimensions, hole positions and flatness.

Cost
What a fence post should cost
Long constant-profile parts (track, rail, trim) from coil; tooled line, cheap by the metre at volume.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a fence post at your volume, in your currency, are in the dossier.

What does a fence post cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $0.83 to 1.8 per part at 1,000 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is a fence post made from?
Common choices are Galvanised steel coil; Aluminium coil; Stainless coil.
What is the main process for a fence post?
Roll Forming. Long constant profiles in high volume: roofing, track, framing and trim.
