Is someone available to visit my vineyard?
Yes, we have both New Zealand and Australian based Sales Engineers.
What lengths are the standard posts?
2.4 m & 2.1m are standard. Other lengths available upon request.
Are there standard hole positions?
Yes, please refer to our website under ‘order forms’.
Can I get specific holes positions?
Hole position is determined by the manufacturing process. But please ask.
What is the lowest hole position to ground level?
Preferred is 300 mm from ground level, however by inserting the post into the ground further, say 50 mm then that will lower the drip line. But caution is needed on anything closer than 150 mm from ground level as this could adversely affect performance of the post.
What post spacing’s do you recommend?
Typically 7.2m is easily achievable, with increased width also likely but will depend on crop loading. Please discuss this with our Sales Engineers.
What is the purpose of the bulge at the bottom of the post?
It adds significant resistance to up & down lift.
What is the purpose of the rolled top?
To prevent snagging’ with bird net protection as well as a safe handling feature.
How do I insert the posts without damaging them?
By using post protector caps and correct installation procedure. Refer to our installation videos.
Can I manually install the posts with a hand rammer?
Yes, but it will depend a lot on the soil type.
How far in the soil should the bulge be?
The bulge sits approx 75 mm from the bottom of the post. The post needs to be inserted 600 mm into the ground.
What post spacing’s do you recommend?
Typically 7.2m is easily achievable, with increased width also likely but will depend on crop loading. Please discuss this with our Sales Engineers.
Do you supply a hand rammer?
Yes hand rammers are available via the Rural Distributor.
Must I use a post protector sleeve when installing mechanically?
It is highly recommended to save the rolled end from wear.
How do I install the intermediate post GRF when required?
By digging a suitable hole diameter to suit. Please refer to our instructional video.
Can you put an ECO TRELLIS ® post next to a broken wooden one?
Yes you can. But leaving broken treated timber posts could allow for further leaching.
What time savings are there over wood for installation?
Depending on soil condition, install of ECO TRELLIS ® can be 2 to 3 times faster than timber.
Do you have installation videos?
Yes, these are available on our website or visit Youtube.
What is the breakage rate of ECO TRELLIS ® posts per year?
Steel is strong, so breakage rates are typically low or non existent.
If you dent a post will they snap or just bend?
Unlikely they will snap, but may bend depending largely on the position of the dent.
What material is the posts made of?
High Strength steel in grade 310 material with a Z450 zinc coating.
Is there other thicknesses of posts available?
Yes, we also make a Mega Post (double ‘skinned’) which is suitable for high wind areas.
Will the posts rust?
Galvanised steel has an expected life span of 15 to 20 years plus. This is dependant on soil type (Ph levels) and environment. Some discolouring may occur over time, but does not affect the structural integrity of the post. Please view our Warranty document via our website.

A simple turn with a screwdriver is generally all that is required.
Does your system work with automated vine strippers / pruners?
Yes, ECO TRELLIS ® has been specifically designed with these uses in mind.
I am not organic why should I switch to steel posts?
Cost effective alternative over the lifespan of the vineyard. And if you wish to change to organic you are already ‘on your way’.
Are there delivery costs?
Yes, because locations vary greatly, some freight expense should be allowed for.
What is the standard delivery time for posts?
Typical lead-time is less than 3 to 4 weeks ex the Mill. Standard posts are available from all good Rural Distributors.

For NZ deliveries there are 182 posts per pack. Based on 2.4 m posts that weigh 770 kgs per pack. Pack sizing is 2550 x 1100 x 700 mm. For outside NZ, typically there are 171 posts per pack. Based on 2.4 m posts that weigh 725 kgs per pack. Pack sizing is 2550 x 1020 x 700 mm.

In what ground conditions should I use a "Standard Harpoon" verses a "Winged Harpoon" ground anchor?
Winged Harpoon Eco Anchor is most suited to sand / silty soil types, whereas the Standard Harpoon Eco Anchor is more suited to solid / rocky soil type.
What's a "Wire Termination Clip" and what are the benefits?
It allows for prevention of trellis wires rubbing directly on to the post.
What are the Strainer dimensions / lengths?
Please refer to our website under “Order Forms”.
How long will the clip last?
UV has an impact on the clip over time and will vary location to location, some discolouration can be expected but this will have no adverse effect. The advice from our clip manufacturer is an expectation of 10 to 15 years plus. Please refer to our Warranty document via our website.
What type of clips are available?
ECO TRELLIS ® has 5 clip options. Please refer to our website under ‘Products & Specifications’.

Yield weights per crop type vary widely, we have experienced up to 50 tonne per hectare without incident.
Can you reuse the clips?
Yes, but not recommended.
Are the clips strong enough to withstand a water based frost protection system?
Yes the clips are capable of working well below freezing.
Is the clip strong enough to withstand day to day requirements?
Yes, in the field experience over the past 6 years without incident would attest to this. We regularly batch test clips and have full supporting data available upon request.
Does another clip colour shorten the lifespan?
As this is a new range, detail on this is not available, but some lesser level could be expected as the UV protection of coloured clips is less than the standard black.
Are they available in other colours?
Yes, but minimum order quantities may apply.
Will the clips become loose over time?
They may, but will not affect the integrity of the clip.
Do you supply a clip that is compatible with auto pruners?

From your Rural Distributor, depending on type and quantity, can range from RRP $0.15 to $0.20 per clip.
How many clips per bag?
Standard Bags are 3000 units. Mini Bags are 1000 and some smaller bags are available of 100 units.
How much does a GRF cost?
RRP is under NZ$4.
What is the ground retention flange for?
