Vineyard Superpost®

Being a Kiwi owned and operated company for over 40 years, Goldpine knows a thing or two about making posts and poles that are up to the job. The Vineyard Superpost®, a member of the wider Superpost® range, is a multi-purpose post suitable for use in vineyards and orchards. The Vineyard Superpost® is strong and durable — a necessity in the vineyard and orchard environment.

High strength. Great value.

A combination of rounded edges and high strength provides great durability which results in low driving and harvest breakages.

360° attachment options

Smooth, curved edges mean the Vineyard Superpost® looks like a round, is easy to handle and gives 360° attachment options.

"I have successfully used Goldpine's Vineyard Superpost in recent developments and I have been really impressed with the way they handle and the way they have driven."

— Jason Tripe — Managing Director, JTC Viticulture

Use wood wherever possible

Rising levels of CO2 are recognised as being associated with global warming and will result in serious environmental consequences if steps are not taken to reduce emissions. Increasing levels of CO2 are a result of burning fossil fuels and tropical rainforest deforestation, whereas new forest growth from both indigenous and plantation forestry can actually remove carbon from the air.

Plantation Pinus Radiata forests in New Zealand are extremely beneficial in combatting the ever-growing emissions around the world. In the lifecycle, a seedling is planted and grows into a tree by sequestering carbon. Once that tree hits maturity and therefore reduces the amount it sequesters, the best result is that the tree is harvested and a new seedling is planted in its place. When harvesting a tree, we need to make use of the carbon store by creating a Harvested Wood Product (HWP), and the longer lasting… the better. It just so happens that a treated fence post has one of the longest lifespans of any HWP.

The world's climate has always changed and human activities have triggered an unusually rapid and severe warming with associated effects such as massive droughts, floods and sea-level rises.

Using timber from certified renewable plantation forests can help to combat these effects. We are extremely proud of our products and, much like the United Nations and the New Zealand Government, we strongly encourage the increased use of wood throughout New Zealand. Use wood wherever possible.


Vineyard Superpost®

Strong and Durable

Produced from the high density, mature trees which gives the Superpost® its high strength.

Strength testing has proven that Goldpine high density Superposts® are significantly stronger than a similar size round.

Their durability and strength is due to the selection of mature, high density wood with Superposts® being cut from further down the tree.

High Density means high strength

Goldpine sources logs from Nelson's high density pine forests, one of only two high density forest regions in New Zealand. Both Scion (formerly the New Zealand Forestry Research Institute) and The Ministry of Primary Industries have independently verified that high density means high strength. Using logs from high density, mature trees is why a Goldpine post is not the same as other posts, it's stronger and that's why products like the Superpost® have a unique "you break 'em and we replace 'em guarantee".

The density comes from the growing conditions that we have in the Nelson region. The climate and slow growing nature means that there's more carbon per square inch. You'll see our growth rings are tightly compact, a visual indication of the density.

More carbon locked away, providing high density roundwood and a stronger fence post for you.

Be Aware of Thinnings

What are thinnings and why are they significant?

Fence posts made from thinnings will not last the distance. Make sure you are buying mature high density wood. Below is a description of the signs to look out for:

Section 1: Cross section of a thinning post

Note the fewer growth rings and the wide spaces between each ring. This is an immature and weak log.

Section 2: Cross section of a mature post

This is cut from a 28+ year old tree and has over 20 tightly packed growth rings. This is a mature and strong tree.

At Goldpine, we have built our reputation on quality product, therefore all Goldpine posts are sourced from mature trees in high density forests.

Treatment Guarantee

The basic process of treating Goldpine posts and poles is simple, highly controlled and constantly monitored. Radiata Pine, which has been peeled and steamed, is loaded onto bogies and pushed into a large horizontal treating cylinder. The cylinder door is hermetically sealed and a strong vacuum removes the majority of air from the cylinder and from the cells of the wood.

CCA oxide is pumped into the cylinder and pressure is raised to about 1400 kPa. This forces the preservative deep into the wood cells. The CCA oxide reacts with the wood sugars to form insoluble precipitates. When the entire sapwood volume has been penetrated with CCA oxide to its intended retention level (eg H5) the treatment process is complete. Excess treatment solution is pumped out of the cylinder and into a storage tank to be reused.

Pressure is returned to normal before the door is opened and the bogies are pulled out. The wet posts and poles are stacked under cover on a concrete floor for at least a week to ensure wood is dripfree and the chemical is completely fixed. The end result of this process is a product which will retain its structural integrity 10-20 times longer than untreated wood.

This earns the posts and poles a 50 year guarantee against fungal or insect attack.

Introducing the patented Rounded Superpost®shape

The Superpost by Goldpine

Retaining all the high strength of a traditional Superpost®, the Rounded Superpost® has the added advantage of looking and handling like a round fencepost.

Smooth, curved edges mean the Rounded Superpost® looks like a round, is easy to handle and give 360? attachment options.
