- Is McAlpines’ timber cut from plantation forests?
- Yes. New Zealand is a world leader in plantation forest management and the pine estate is managed on a sustained yield basis.
- What are the machining properties of New Zealand pine?
- The superior machining properties and its ease of moulding, turning, planing, joining and furniture manufacture are strong features of New Zealand 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 and Asia for higher value products.

- Does McAlpines kiln dry its timber?
- Yes. Both McAlpines sites hold a “NZ Dri Licencee”. We take price in producing high quality, stress free, consistently dried, New Zealand Pine. We have eight high temperature kilns across the two sites and can dry all our production.
- Does McAlpines preservative treat our timber?
- When timber is tantalised it is resistant to fungal degrade and insect attack. New Zealand pine’s sapwood is extremely permeable to preservatives, permitting total penetration rarely achieved with other softwood species. McAlpines uses Tanalith CCA in H3 (exposed to weather) and H4 (ground contact/landscaping). Products include post, palings, decking, framing etc.
- Does McAlpines use anti-sapstain/ bluestain treatment?
- Yes. McAlpines uses Hylite Clear (liquid fungicide and anti-sapstain).
- Is New Zealand pine easy to stain?
- Our pine is an extremely versatile wood and and readily accepts the many stains that are available with extremely good penetration and consistency.
- How is the timber transported?
- McAlpines’ domestic timber is transported through out New Zealand in full truck and trailer loads (FTL). The majority of McAlpines’ export timber is shipped in 40-ft containers and the balance is shipped break-bulk. Transit times range from 1-4 weeks.
- How many m3 fill a 40 ft container?
- Approximately 38 – 42m3, depending on dimensions and lengths required.
- What lengths does McAlpines supply?
- McAlpines supplies domestic timber in select length packets ranging from 3.6 to 6.0 m dependent on the product. McAlpines supplies export timber in random length packets from 2.4 to 6.0 m (heavy 4.2 – 6.0 unless agreed otherwise).
- What size timber does McAlpines produce?
- Standard thickness produced is 50mm and arising from this McAlpines produces 25 and 40 mm. The widths vary between grades. Please refer to our McAlpines’ products page.
- What are McAlpines’ general terms of payment?
- Irrevocable letter of credit payable on sight of documents or TT payment prior to shipment in US dollars.
- Can McAlpines dress or gauge its timber?
- Yes. We produce a range of timbers with different finished, including dressed 4 sides, tongue and groove, decking, rougher headed and gauged structural framing.
- How much timber does McAlpines export?
- Over 25% of our production is exported to countries such as China, Indonesia, Malaysia, Vietnam, Thailand and Taiwan. We also supply treated construction products for the resort construction market in South East Asia and the Indian Ocean.
