Vineyard Posts: Practical Comparisons Between Steel and Wood Posts
Especially for commercial-sized vineyards where wine production undergoes a series of intricate and manual processes, the use of vineyard posts as part of a trellising system is important. While there are other parts of a trellising system such as the stakes, wires, repair clamps (when needed), clips and fasteners, the vineyard post has a more important role since it keeps the entire trellising system together.
Vineyard posts are available in 2 materials: wood or steel. While these provide the same anchorage for a trellising system, they also have their differences such as internal composition, sustainability and appearance. Here are 3 reasons why:
1. Steel vineyard posts are easier to use and install than wood vineyard posts. When installing wood posts to hang your wires, you have to dig at least 2 feet of soil and fit it to the ground. You also have to add in concrete to keep it stable and let it set for a while. The process entails a lot work and additional resources but when you opt for the steel posts, you just have to forcefully drive it to the ground and it is already sturdy enough to stand upright for use. Also, majority of steel posts are thick thereby allowing these to handle the load of the trellises and the tension that needs to be applied to the wires.
2. Steel vineyard posts are more versatile than wooden ones. Unlike wood posts, steel posts come with slotted holes or wire holes on the top so you can easily string your wires together with another post. When posts have wire holes in them, you don’t have to buy clips, staplers, fasteners or ties to keep your wires to the post. Another reason, steel posts are more presentable and aesthetically pleasing than wooden ones.
3. Steel posts are better at grounding lightning than wood posts. Vineyards are usually found in very wide spaces. The vastness of the lot is ideal since grapevines need to be exposed to a lot of sunlight and wind for photosynthesis. However, large plots of vineyards no matter how ideal for sun and wind exposure are also susceptible to natural calamities such as typhoons and lightning. When wood posts are struck by lightning, it might break and burn down and eventually, cause damage to the trellises and the grapes that you have been tending to so carefully. Steel posts will repel and ground lightning easily when lightning happens.
