A vineyard trellis is a long-term investment. Every component, from the steel post to the wire attachment, needs to withstand years of exposure to rain, moisture, temperature changes and the demands of normal vineyard operations.
That is why AgSteel uses purpose-selected Ruspert-coated drill-point screws with its Vinepost clipping system.
Coated steel fasteners have long been used in roofing and other exposed building applications, where reliable performance is essential. Roofing fasteners must withstand years of weather exposure and seasonal temperature changes while continuing to hold steel components securely.
The Ruspert coating used on AgSteel Vinepost screws is based on this established approach to protecting steel fasteners in outdoor environments.
Unlike a basic zinc-plated finish, Ruspert is a three-layer corrosion-protection system:
This combination provides both barrier protection and sacrificial protection, helping preserve the integrity of the steel fastener over extended outdoor service. Zinc protects carbon steel by corroding sacrificially before the underlying steel, while Ruspert adds conversion and ceramic layers to enhance the overall protection system
Vinepost clips are exposed to more than rain. They must perform through changing seasons, vineyard spraying, wire movement, wind loading, pruning and mechanical harvesting.
The fastening system therefore needs to do more than resist corrosion. It must also provide a secure mechanical attachment throughout its service life.
Unlike an attachment that depends entirely on a moulded plastic locking feature, the AgSteelTM clip is mechanically secured by a coated steel screw. This provides a strong and dependable connection while retaining the flexibility and replaceability of the nylon clip.
The screw coating was not selected merely to delay visible surface staining. It was selected to help maintain the functional integrity of the fastening system over the long term.
Ruspert-coated fasteners are used across demanding applications, including:
Ruspert-coated fasteners are specifically marketed for steel structures, roofing systems and industrial installations where corrosion resistance and long-term durability are required.
By combining a high-performance Ruspert-coated screw with a durable nylon clip and a robust steel Vinepost, AgSteelTM provides a practical, secure and replaceable wire-attachment system designed for long-term vineyard service.
AgSteel Vinepost screws are protected for the conditions and built to last.
We have designed the Vineposts to allow for the use of the Klima machine. The posts tear drop design allows for the commonly used Klima screw in clip, installed with a tek screw, to be used on the posts.
When completing the Vinepost order form, the customer can select specific clip spacing to meet requirements. These can be made custom to the customers specifications.
