Stress Tested Wooden Poles

NZ Poles are one of the few suppliers worldwide that can offer verified stress testing on all of your poles. All our Stress Tested Wooden Poles are individually tested for stiffness, similar to how machine stress graded timber is verified in an "E grader" process. Each Timber pole is loaded into a purpose built proof tester, that can handle up to 22m... the largest proof tester in the southern hemisphere! Once the pole is loaded, hydraulic rams press and deflect the pole to preset distances and measure the deflection at different points along the pole. The results of the test are then printed on an aluminium tag that is attached to the pole before it is dispatched, which allows engineers and designers to rely on the strength and stiffness of the poles.

Stress tested and verified poles provide customers with piece of mind that each pole is exactly as strong as it claims to be.
