A flat-profile structural line post
A vertical steel post that runs your row, spaced to carry the wire framework that trains the canopy from a single-wire VSP row to a multi-wire T-trellis.

Flat-Edge Vertical Line Post
Flat-Edge Vertical Line Posts run the length of your vineyard or orchard row, spaced to carry the wire framework that trains the canopy — from a single-wire VSP row to a multi-wire T-trellis. The flat face gives U-bolt clips a clean, consistent bearing surface, so wire heights stay uniform and symmetrical down the row. Specify gauge, length and finish to match your system, crop and soil.

Gauge, length and finish
12, 13, and 14 gauge (2.5, 2.3, and 2.0 mm); 7–18 feet lengths; plain, zinc-plated, or hot-dip galvanized finish.
Flat face for consistent wire attachment
The flat face gives U-bolt clips a clean, even bearing surface, so wire heights land in the same place post after post. It runs as primary line-post support, spaced down the row to match your system, soil and wire configuration.
Also known as
Flat-Edge Vertical Line Posts are ordered as line posts or vineyard posts, piquet de vigne in France, Rebpfahl in German-speaking markets, palo per vigneto in Italy and poste de acero in Spanish.

Drive the post with the flat face to the row
Drive the post into the soil at row intervals with the flat face oriented toward the row. Seat U-bolt clips against the flat bearing surface so wire attachment stays consistent and symmetrical across multiple posts, holding the canopy geometry steady through seasonal loading and vine growth.
Choosing between
Rolled edge or flat edge.
Both posts carry the wire down a vineyard or orchard row. The edge profile decides whether you gain extra strength or a clean face for wire work.
Common applications
Where it is used.
Wine grape systems with precision canopy geometry
Run flat-edge posts in your VSP or Scott-Henry rows for repeatable wire attachment — uniform clip placement across multiple posts keeps canopy geometry precise enough for mechanical harvest.
Table grape T-trellis systems
Mount cross-arms to flat-edge posts in your T-trellis row — the flat face carries the lateral loads from the arm assembly and canopy weight while keeping wire attachment symmetrical.
Orchard espalier and raisin DOV training
Apple and pear espalier rows and raisin DOV open-gable systems both anchor flat-edge posts for precise wire-framework alignment: the flat face keeps horizontal and vertical wires true across multiple posts in espalier training, and holds the V-shaped post-top arrangement that lets canes dry in place on the vine in DOV systems.
Questions answered
Common questions.
What are flat edge line posts called in different regions?
Flat-Edge Vertical Line Posts for vineyard and orchard systems are ordered as line posts or vineyard posts in English, piquet de vigne in France, Rebpfahl in German, and palo per vigneto in Italian. The flat edge is the post face design.
What specifications are available for vineyard and orchard line posts?
Flat Edge Line Posts for vineyard and orchard systems are manufactured in various gauges and lengths for row support and wire suspension. Available finishes include plain, painted, and hot dip galvanized for durability.
A clean, consistent bearing surface for wire attachment
The flat face gives U-bolt clips an even bearing surface, so wire heights stay uniform and symmetrical across every post in the row — precise enough for mechanical harvest and true espalier alignment. It runs as line-post support across VSP, T-trellis, DOV and orchard systems, in coordinated gauges and lengths. If your rows carry heavier tension or wind load, the rolled-edge profile carries more.
