Q. What is NZ Pine's strength properties?

A. NZ pine's strength and stiffness properties generally cover the range of commonly used structural softwoods.

Q. Is TimberX timber cut from plantation forests?

A. Yes. New Zealand is a world leader in plantation forest management and the pine estate is managed on a sustained yield basis.

Q. What it's machining properties?

A. The superior machining properties and its ease of moulding, turning, planing, joining and furniture manufacture are strong features of NZ pine.
Comprehensive trials conducted at NZFRI, in the United Kingdom and by the University of California have shown that New Zealand pine compares very favourably with softwood species commonly used in Europe, North America & Asia for higher value products.

Q. Does TimberX kiln dry it's timber?

A. Yes. TimberX as a "NZ Dri Licencee" prides itself on producing high quality stress free and consistently dried New Zealand Pine.

Q. Do we preservative treat our timber?

A. When timber is tantalised it is resistant to fungal degrade and insect attack. NZ pine's sapwood is extremely permeable to preservatives, permitting total penetration rarely achieved with other softwood species. We uses Tanalith CCA in H3 (exposed to weather) and H4 (ground contact/landscaping). Products include post, palings, decking, framing etc.

Q. Does Southpine use anti-sapstain/ bluestain treatment?

A. Yes. Southpine uses Hylite Clear (liquid fungicide and anti-sapstain).

Q. Is NZ Pine easy to stain?

A. Our pine is an extremely versatile wood and and readily accepts the many stains that are available with extremely good penetration and consistency.

Q. What are TimberX lengths?

A. TimberX supplies random lengths from 1.8 to 6.0 m (heavy 4.2 - 6.0 unless agreed otherwise).

Q. What sizes does TimberX produce?

A. Standard thickness are 25, 32, 40 and 50 mm. The widths vary between grades. Please refer to our TimberX products page.

Q. Can TimberX dress or gauge its timber?

A. Yes. We produce a range of timbers with different finished, including dressed 4 sides, tongue & groove, decking, rougher headed and gauged framing.

Q. Does TimberX also sell clear timbers?

A. Yes, in random or cut to length.

About CCA Wood

Q : Can CCA wood be painted or stained ?

A : Yes, after drying,CCA wood can be painted or stained the same as untreated wood.

Q : Can CCA wood be used around people, plants, and pets ?

A : CCA wood has a history of 60 years of safe use. Most concerns about treated wood

arise from confusion between the preservative and the preservative-treated wood.

In laboratory tests, in garden and vegetables studies, in investigations of playground structures,

in surveys of carpenters and treating plant workers, and in other research conducted by various organizations,

CCA treated wood has been shown to be harmless when used as recommended.

Q : How do CCA preservatives protect the wood from termite attack and fungal decay ?

A : The chemical used to preserve CCA pressure-treated wood is a mixture of

he oxides of copper, chromium, and arsenic known as CCA. The preservative has been formulated to render

wood useless as a food substance for termites and fungi while keeping the wood attractive, clean,

on-staining, and safe to handle when used as recommended.

Q: How long will CCA wood last ?

A : When used in applications for which it is intended, CCA wood will last for decades.

In most residential and agricultural projects, we guarantee that CCA wood will not experience

structural damage from termites or fungal decay for the lifetime of the purchaser.

Q: Is all CCA wood treated the same way and can I use it for all applications ?

A : All CCA wood is pressure treated to meet the standards of the New Zealand Wood Preservers? Association.

When purchasing CCA pressure treated wood be aware that different applications require different

amounts of preservative. The retention or appropriate end use is indicated on a label or ink stamp on the wood.

Q: What is CCA pressure treated wood ?

A : CCA wood is lumber or plywood that has been pressure-impregnated with an effective preservative

which makes the wood resistant to attack by termites and the fungi that cause decay.

Q: Will treating lumber with CCA preservatives change the grade of the lumber ?

A : No. Treatment does not effect the grade; it simply makes lumber last longer.

Treated wood is available in different grades, determined by certified graders.

Q: Will CCA wood be accepted by the local building department?

A: CCA wood is treated under the strict guidelines of the New Zealand Wood Preservers Association.

The New Zealand Lumber Standards Committee is responsible for the oversight and accreditation of third party

inspection agencies for treated wood. In order to comply with the Uniform Building Code, {UBC} treated wood

must be marked with the quality stamp or end tag of an accredited agency. CCA wood will meet the requirements

of the Uniform Building Code.
