Product Description
C1 Maxi Zincor (Corten + HDG Bottom) Line Posts
Manufacturer: Consortium SPA (Italy)
Premium hybrid vineyard posts combining Corten weathering steel aesthetics with hot-dip galvanized underground protection. Zincor dual-coating technology delivers the rustic appearance of weathering steel above ground while providing superior corrosion resistance in acidic soils. Perfect solution for wine tourism vineyards requiring both visual appeal and maximum longevity in challenging soil conditions.
Technical Specifications

Engineering Features
- Hybrid Protection System: Combines Corten aesthetics above ground with HDG corrosion protection below ground
- Acidic Soil Solution: HDG bottom section prevents Corten degradation in low pH conditions while maintaining weathered appearance above ground
- Roll-Formed Steel Construction: 60mm x 40mm profile with 32mm open channel protects against mechanical shock from harvesters and equipment
- Harvester-Friendly Design: Non-protruding recessed hooks protected by post profile prevent damage to beater bars during mechanical harvesting
- Enhanced Structural Features: Back ribs combine flexibility with high mechanical resistance; stamped notches prevent closure during mechanical contact
- Wine Tourism Optimization: Maintains natural weathered appearance while ensuring underground longevity in challenging soil conditions
- Transition Zone Engineering: Carefully engineered junction between coating systems prevents galvanic corrosion
- Extended Service Life: Approaches HDG longevity (30+ years) while maintaining Corten aesthetics above ground
Installation & Performance
- Maximum Post Spacing: 18' (enhanced underground protection supports full structural integrity)
- Installation Method: Pneumatic driver recommended for optimal positioning of transition zone
- Soil Compatibility: Universal - specifically engineered for acidic soils where standard Corten fails
- Premium Application: Ideal for high-end wine tourism installations requiring both performance and aesthetics
All notches and hooks are on 4" centers
Custom lengths and notch/hook patterns are available upon request.
Other Details
- Additional Information:
The C1 Maxi range of steel line posts is a series of high quality roll-formed medium/heavy weight vertical line posts designed for use as vineyard trellis line posts. The C1 Maxi posts are available in a range of structural steel qualities with a choice of coatings and a choice of wire notches (for fixed wires) and/or wire hooks designed to easily manage moveable catch wires during the wire lifting phase of canopy management. The C1 Maxi wire hooks are designed to be gentle on harvesting machines with a specially designed recessed hook which is protected by the outer edge of the post, thereby avoiding damage from machine harvesters.
In addition to two types of zinc coatings; strip galv (18-25µ of zinc per side) and HDG (60-80µ of zinc per side), the C1 Maxi post can also be produced using corten steel as well as a combination of Corten + HDG. Corten steel is a type of high strength weather resistant structural steel commonly used for the construction of bridges and guardrails. Corten steel forms a protective barrier of corrosion which prohibits further corrosion of the interior steel. While arguably a great choice for many vineyard sites, Corten posts should be avoided if acidic soils are present. In the event of soil ph less than 6.5, the C1 Maxi post is available with the bottom portion of the post (portion of the post to be driven into the ground) with HDG to avoid corrosion of the Corten steel.
The C1 Maxi 2.36" x 1.57" post profile combined with heavy structural steel construction produces a strong post, with a suggested post spacing not to exceed 18' (dependent upon factors such as expected crop yields, training system, soil type, row direction, etc...). Depending upon soil ph and moisture content, the lifespan of the C1 Maxi HDG post can last up to 35-40 years while the typical lifespan of the strip galv and corten posts can last 10-30 years. Wire spreaders and fixed wire clips are available for use on the C1 Maxi post.
