Our Fence Posts

Being located in the Golden Downs region in the heart of the Nelson, we are able to source our wood from high density forests. These high density trees give our posts their great strength. We source mature trees with an average age of 28 years which ensures our posts, poles and piles are the most durable available.

Almost 40 years experience in fencing

One of the most crucial elements to the success of Goldpine is the constant research and development undertaken to improve products and fencing solutions.

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.

Beware of Thinning

What are thinnings and why they are 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 grows 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.
