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.

Which plywood grade do I need?


CD (C face, D back)

Front face is C — all holes and splits filled and sanded. Holes should not exceed 50mm. Intergrown knots should not exceed 50mm measured across the width of sheet. This face grade is suitable for basic paint finish and is used in many structural applications — roofing, flooring, claddings, hoardings, formwork etc. Back face is D — as per spec below.

DD (D face, D back)

Front and back face of sheet is D grade — unfilled holes allowed not exceeding 75mm measured across the width of sheet. No limit on size and number of knots. Open splits allowed up to 25mm. This face grade is suitable in many structural applications also where open holes and knots are not an issue or are not seen — sheds, barns, bracing, bins, pallets, kennels, fencing etc.

DD non structural / 2nds

Non structural means individual veneers have not met strength requirements of AS/NZ2269. 2nds have obvious defects such as edge gap, over size knots and holes.
