Galvanised steel vineyard posts are the ideal choice for growers seeking strength and durability in demanding agricultural environments. The galvanisation process provides exceptional protection against corrosion, making these metal vineyard posts suitable for a wide range of climates and soil conditions.
Sika manufactures a complete range of vineyard trellis posts, including both line posts and end posts, available in galvanised steel and corten steel.
Hot-dip or pre-galvanised: the difference that matters
Not all galvanised posts are the same, and the difference lies in when the zinc is applied.
Hot-dip galvanising after forming. The post is shaped first, then immersed in molten zinc. Zinc covers the entire piece, including slots, cut edges and punched areas, which are the points where corrosion starts first. The zinc layer is thicker, significantly extending service life in demanding conditions. This is the recommended choice for humid or saline sites and for vineyards under intensive spray programmes.
Pre-galvanised strip. The post is formed from sheet that is already coated before processing. The finish is uniform on flat surfaces, while cut edges remain exposed. These posts are lighter, which makes handling and installation easier in the field. It is the more economical option within the galvanised range and remains fully adequate in most conditions.
Sheet thickness ranges from 1.8 mm to 2 mm across both variants.
Steel posts for vineyards. Reliable and adaptable for all systems
Metal vineyard posts made of galvanised steel are valued for their durability, strength, and installation efficiency. These posts are compatible with both traditional and modern training systems, such as Guyot trellising, making them a versatile solution for vineyard installations of any scale. They are also designed for full compatibility with mechanical harvesters and pruning equipment, with no need to re-tension the wires after harvest.
The ability to combine galvanised posts with corten options gives growers the flexibility to tailor their trellis structure based on local terrain, climate, and operational needs.
End and line posts. Full support for efficient, turnkey vineyard installations
Vineyard end posts anchor the structure at each row’s termination point and absorb the combined tension of every wire in the row: available in Mini Strong 56 x 46 mm and Strong 68 x 56 mm sections. Vineyard line posts distribute the load evenly along the row, maintaining proper wire tension and supporting the vines: available in Small 51 x 33 mm, Medium 51 x 41 mm and Big 65 x 45 mm.
Galvanised vineyard accessories
The galvanised range extends beyond posts: helical ground anchors, galvanised trellis wire, anti-sink plates for end posts and galvanised rods for concrete anchor bases. All designed to work with Sika posts as a single system.
Vineyard accessories. Essential components for a complete and efficient trellis system
To complete the trellising setup, Sika offers a wide range of vineyard supplies, including:
- Galvanised vineyard trellis wire
- Wire tensioners
- Vine ties
- Training stakes
- Spring strainers
- Hooks and wire spacers
Each component is engineered to maintain system integrity, simplify day-to-day vineyard management, and promote healthy plant development over time.
An aesthetic and functional alternative: corten vineyard posts
For those seeking both visual harmony and performance, corten vineyard trellis posts are a top choice. Their rust-coloured patina blends naturally with the surrounding landscape, making them ideal for vineyards located in scenic or tourism-driven wine regions.
At equal profile and thickness, corten posts cost on average 20% less than the galvanised equivalent, because they require no galvanising process after forming. The natural weathering process forms a protective layer that prevents further deterioration and extends service life, making them a sustainable, long-term investment.
