A rolled-profile structural line post
A vertical steel post that runs the length of your row, spaced to carry the wire framework that trains the canopy from a single-wire VSP row to a full cross-arm T-trellis.

Rolled Edge Vertical Line Post
Rolled Edge Vertical Line Posts run the length of a vineyard or orchard row, spaced to carry the wire framework that trains the canopy — from a single-wire VSP row to a full cross-arm T-trellis. The rolled edge keeps the wire seated cleanly against the post, so tension stays even along the row instead of slipping. Specify height, gauge 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; carbon steel; plain, zinc-plated, or hot-dip galvanized finish.
Built for bend resistance under load
The rolled edge stiffens the post's cross-section, so it resists bending under row tension, wind load and a heavy canopy — the added strength that makes it the stronger of Corona's two line-post profiles. It runs as primary support for wire tension, spaced down the row to match your system, soil and wire configuration.
Also known as
Drive the post to carry wire tension
Drive the post into the soil at row intervals, spaced to carry the cumulative wire tension from your trellis framework. The rolled edge keeps wire seated flat and secure as loading builds through the season, holding wire positioning and row consistency whether you're running a single-wire VSP or a multi-wire T-trellis.
Common applications
Where it is used.
Wine grape vertical shoot positioning (VSP)
Run rolled-edge posts down your VSP row to support the single upright canopy and catch-wire array — even spacing keeps wire attachment uniform, so a mechanical harvester runs straight through without adjustment.
Table grape T-trellis systems
Mount cross-arms to rolled-edge posts spaced down the row to carry the bilateral cordon training and multi-wire geometry that spreads your canopy wide for table-grape production.
Raisin, orchard and open-gable training
Raisin DOV open-gable systems anchor rolled-edge posts at the V-shaped post-top arrangement to hold the multi-wire fruit support that lets canes dry in place on the vine, and apple and pear espalier systems rely on the same posts as primary frame support for the multi-level wire framework that keeps bilateral cordons trained in position year after year.
The stronger of Corona's two line-post profiles
The rolled edge stiffens the post's section, giving you more strength and better bend resistance than a flat-edge post under the same row tension, wind load and canopy weight. It runs as the primary line-post support across VSP, T-trellis, DOV and orchard systems, in coordinated gauges and lengths so you can match it to your row.
