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.

Flat-Edge Vertical Line Post at a glance.

Definition

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.

Product form

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.

Installation advantage

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

Also called vineyard posts in the US. Spanish-speaking crews call it poste de acero.

US English: vineyard post
Español (US): poste de aceroposte intermedio

How it works

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.

Rolled Edge Vertical Line Post
Choose rolled-edge posts when the row experiences heavy wire tension, wind loading, or substantial canopy weight, and you want maximum bending resistance.

Choose flat-edge posts when you want a consistent face for securing clips and wire along the entire row.

Common applications

Where it is used.

Application

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.

Application

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.

Application

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.

What else are flat-edge vertical line posts called?

In the US, they are called line posts or vineyard posts. In Spanish, they are palo per vigneto. The flat edge is the post face design.

What specifications are available for vineyard and orchard line posts?

Flat-edge vertical 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.

Vineyard & Orchard Systems

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.
