The right vineyard supplies make any trellis system more efficient and longer lasting. For this reason, Sika manufactures a wide range of vineyard trellis supplies and vineyard accessories. They meet the needs of every vineyard type, from traditional setups to the most advanced installations.
Vineyard wire: galvanised and corten
Vineyard wire carries the entire load of the canopy and takes the tension of the whole row. Sika supplies it in two versions.
Galvanised vineyard wire is the standard choice for both the fruiting wire and the foliage wires. In fact, it offers the best balance between tensile strength and cost. Corten trellis wire, on the other hand, is the natural match for corten posts. It keeps the row visually consistent and avoids the contrast between a weathered post and a bright wire.
To choose the right gauge and wire heights, read our guide to grape trellis wire gauge and spacing.
Tensioning systems
Wires lose tension after every harvest and across the seasons. Stainless steel wire tensioners work with a key and hold their position without slipping. Spring strainers, instead, absorb length changes from thermal expansion and sudden loads. As a result, they reduce stress on the end posts. Finally, a chain tensioner offers a wider adjustment range when you need it.
Anchors and base plates
An end post needs an anchoring system sized for the row load. Vineyard ground anchors with a concrete base and galvanised shaft are the traditional solution for most soils. Helical anchors, however, screw into the ground without excavation. Where the soil has good cohesion, they cut installation time. In softer ground, anchor plates spread the load and stop the post from sinking.
For a full guide on sizing and installing anchors, see how to anchor grape trellis posts.
Vine ties, hooks and spacers
Stainless steel vine ties secure the canes to the wire. Unlike plastic ties, they do not cut into the wood as the trunk thickens. Wire hooks, also known as wire locks, hold the moveable foliage wires in position during canopy growth. This way, you can raise or lower the wires without dismantling anything. Meanwhile, wire spacers keep the correct distance between wire levels. Consequently, they improve light exposure and machine access.
Training stakes for young vines
Vineyard stakes in Ø 7 mm and Ø 8 mm guide young vines through their first years, until the trunk reaches the fruiting wire. Steel stakes do not rot and do not become brittle. Moreover, unlike wooden or plastic alternatives, you can recover them and reuse them in later plantings.
Fully integrated with Sika vineyard trellis posts
We design every accessory to work with Sika’s post systems. These include line posts and end posts in galvanised steel or corten. In addition, the slots on the posts accept wires and hooks without any field modification.
