The introduction of Corten steel vineyard trellis posts has marked a major turning point in modern viticulture. Sika, one of the pioneers in Italy in the use of this material, has helped make Corten vineyard posts the most widely adopted solution in vineyard trellising today.
These rust-colored vineyard posts stand out not only for their cost-effectiveness—on average 20% less expensive than other materials of the same profile and thickness—but also for their exceptional corrosion resistance and visually appealing look, which improves over time.Thanks to their natural passivation process, they form a protective outer patina that prevents further corrosion and gives the posts their signature finish, perfectly blending into the surrounding landscape.

Looking for cost-effective vineyard posts without compromising on strength or quality?
Corten vineyard posts are a smart choice for growers who need a durable, low-maintenance trellis solution. Thanks to their high mechanical strength and natural corrosion resistance, these posts significantly reduce the need for frequent replacements, delivering considerable long-term savings. Even with recent price increases driven by supply and demand fluctuations, their lower upfront cost still makes Corten steel vineyard trellis posts a highly economical and sustainable option for modern viticulture.
Minimal environmental impact
The rust-colored finish of Corten vineyard posts blends naturally into the landscape, reducing the visual impact of trellis structures and enhancing the overall aesthetic harmony of the vineyard environment.This feature is especially valued in wine-growing regions where the visual appeal of the landscape plays a key role in tourism and local identity.
Versatile applications with Corten vineyard accessories
Beyond line and end posts, Corten steel is also used to produce a wide range of vineyard accessories, including vineyard wires, anti-sink base plates for end posts, and training stakes for young vines. This versatility demonstrates the adaptability of Corten to various trellising needs, offering complete, corrosion-resistant solutions that meet both functional and aesthetic requirements of today’s vineyard professionals.
Galvanized alternative. Zinc-Coated steel vineyard posts
For those seeking an alternative, galvanized steel vineyard posts offer additional protection against corrosion, thanks to a hot-dip galvanization process that fully coats the post with a protective zinc layer. This option is ideal for vineyards in high-humidity or saline environments, where corrosion resistance is critical to long-term performance.
Why choose Sika vineyard end posts
Choosing Sika vineyard end posts means investing in a trellising solution that not only improves vineyard efficiency and productivity, but also delivers long-term savings due to its durability and low maintenance requirements. With Sika, growers can count on a reliable solution that protects the crop and supports vineyard growth year after year.
Innovative materials and technology for high-performance vineyard posts
Sika vineyard posts are made from high-quality materials, carefully selected to ensure superior performance and extended lifespan. We primarily use three types of steel, each offering specific properties and benefits:
- Corten steel is widely valued for its excellent corrosion resistance. It undergoes a natural passivation process, forming a protective patina that shields the material from environmental elements. This not only ensures durability but also allows the post to visually blend into the natural landscape, minimizing its visual impact.
- Hot-Dip galvanized steel is treated after profiling, creating a thick and uniform zinc coating that significantly enhances corrosion resistance. It’s the ideal choice for vineyards in particularly humid or coastal areas.
- Pre-galvanized steel is zinc-coated before profiling. This ensures full coverage, even in hard-to-reach areas, providing an added layer of protection against environmental damage.
Installation and maintenance of Sika vineyard trellis
Installation of line posts
Sika line trellis posts are designed for quick, effective installation. We recommend placing posts 4 to 5 meters apart to ensure system stability. In windy areas, spacing should be reduced to increase wind resistance. Posts should be inserted 60–70 cm into the ground. Whether made from Corten or galvanized steel, Sika posts are suitable for various soil types, including rocky ground where pre-drilling may be needed. These materials provide excellent durability and are easy to handle during installation.
Installation of end posts
End trellis posts should be installed at a 45° to 60° angle and driven 15–20 cm deeper than line posts to guarantee secure anchoring. We also recommend using double wires between the end post and the anchor to maximize row stability. End posts can be installed manually using a post driver for fast and efficient setup.
Vineyard accessories for a complete trellis system
To complete your trellising system, Sika provides a wide range of vineyard supplies designed for maximum functionality and durability. These include stainless steel wire tensioners, tensioning springs, vineyard wire spacers, and vine hooks, all of which help maintain proper wire tension and spacing for optimal vine growth.
Additionally, we offer vineyard anchors with concrete bases and galvanized rods, as well as galvanized vineyard wire and Corten wire, both engineered for strength and corrosion resistance. All accessories are fully compatible with Sika vineyard posts, creating a cohesive and long-lasting support system.
Cold-forming technology. Precision engineering for maximum performance
Beyond material selection, Sika’s cold-forming technology is key to producing reliable vineyard posts. This advanced process shapes the steel at ambient temperature, preserving its mechanical properties while ensuring superior dimensional precision.
Cold-forming results in stronger posts with customizable profiles that meet the technical and structural needs of modern vineyards. This precision not only improves trellis performance but also makes installation and maintenance easier—saving time and operational costs.
