Strength by Nature

About E-frame™ SG Timber

A New Zealand First…
Pinepac was the first New Zealand Sawmill to install the model 200 Rotary E-grader™. It is scientifically proven that the grading methods used by this machine provide a more accurate way of predicting our timbers performance and compliance with structural standards (AS/NZS 1748). The E-grader™ produces machine graded timber to a consistently high standard. The timber is processed through this machine on its edge, which means that the timber is tested using its true structural orientation, delivering you Pinepac E-frame™.

e-graderPinepac E-frame™ is processed through the latest machine stress grading equipment. The E-grader™ was designed by internationally recognised engineering specialists at Forest Research who along with Falcon Engineering jointly won the Forest Industries Engineering Association ‘Technology Innovation Award’ for the development of the machine.

NZS 3604 and SG Graded Pine
New Zealand Forest Research scientists have evaluated the requirements of the standard and have compared that with the strength properties of SG8. From that study published in their Sawmilling Bulletin, they have reached the following conclusion: “SG8 may be safely sold as a direct substitute for Radiata Pine visually graded No.1 framing”.

Grade markings are provided to identify the specific grades of timber, these are identified by a series of colour coded paint flashes applied to the face of the timber as it passes through the machine.

The E-grader™ has the ability to stress grade specialised products such as beams, squares, piles and scaffold planks. Pinepac can now supply either rough sawn or machined kiln dried E-frame™ in sizes from 75x40mm upp to 300x100mm. Pinepac E-frame™ is available in a variety of lengths from 2.4 to 6.0 metres.

E-frame™ can be supplied in treated or untreated form. Specifications include H1.2 or H3.1 for approved above ground building use. Refer also to Woodmark® quality assurance.
