Choosing the Right Orchard Support System for Long-Term Crop Success

A well-designed orchard support system is one of the most important investments you will make in the future performance of your orchard. The right structure needs to do more than simply hold up vines — it needs to support healthy growth, manage increasing crop loads, withstand demanding outdoor conditions, and protect the long-term productivity of your land.

At Ag-Steel™, we understand that every orchard represents years of hard work, planning, and investment. That’s why we manufacture support systems designed specifically for New Zealand horticultural environments — helping growers produce the premium kiwifruit New Zealand is recognised for.

What makes a good orchard support system?

Choosing the right orchard structure comes down to more than selecting individual components. A reliable system needs to work together as a complete solution, providing strength, stability, and durability throughout the life of the orchard.

A quality support system should:

• Provide reliable support as vines mature and crop weights increase
• Withstand New Zealand’s varied weather conditions
• Maintain structural integrity in corrosion-prone outdoor environments
• Allow efficient orchard management and harvesting practices
• Support future orchard development and changing crop requirements

Whether you are establishing a new orchard, converting varieties, or strengthening an existing block, selecting the right materials and design from the beginning can make a significant difference over the long term.

Built for New Zealand orchard conditions

The Ag-Steel™ range is manufactured in New Zealand using high-strength GS310 pre-galvanised steel tube, featuring a Z450 zinc coating with external weld seam zinc repair to maintain coating continuity.

This manufacturing process delivers a smooth, consistent surface finish with excellent formability, making Ag-Steel purpose-built for outdoor applications where corrosion resistance and long-term durability are essential.

Ag-Beam™ is available in standard 1.15mm and Heavy 1.55mm wall thickness depending on your orchard requirements.

A complete orchard support solution

Every orchard has different requirements depending on crop type, location, planting design, and future growth expectations. That’s why Ag-Steel offers a complete range of support products designed to work together as part of a robust orchard system.

The range includes:

• Ag-Beam™ — supporting the row structure. The Ag-Beam™ provides the main support structure across the orchard row, helping carry the weight of mature vines and increasing crop loads.
• Ag-Brace™ — strengthening the system. Bracing is essential for maintaining stability and transferring loads through the support structure, particularly as vines mature and crop weights increase.
• Stringing Poles — encouraging new vine growth. Stringing poles help guide and support developing vines, creating an organised canopy structure and assisting with orchard management.
• Replacement Posts — restoring and strengthening existing orchards. For growers upgrading existing blocks, Ag-Steel replacement posts provide a reliable option for improving support where existing structures require additional strength or renewal.

Supporting growers through orchard change

The horticulture industry continues to evolve, with many growers adapting existing orchards through variety changes, including grafting golden or red kiwifruit onto established green blocks.

These changes can significantly increase future vine weight and crop loads, making it important to review whether existing support structures are suitable for the next stage of production.

The Ag-Steel team provides technical guidance for growers planning new developments or preparing existing orchards for increased demands. By understanding the challenges growers face, we can help identify the right support solution for each application.
