SED Construction Poles

The Term SED stands for small end diameter and is how all Construction Poles are measured and graded in accordance to size. All SED Construction Poles have a natural taper of 6-8mm per metre of length from the SED down to the LED (large end diameter).

Roundwood New Zealand Construction Poles are one of the main product lines we manufacture and can range from 1.8m to 20m lengths, and from 125mm - 550mm in SED.

Logs are cut to length and graded onsite once arriving from the Forest in accordance to the New Zealand Standard (NZS) NZS3605, to ensure each pole complies with this specification. The form of each pole is surveyed for taper and straightness before it goes through the Peeling process.

This process takes a very small outer layer off the log transforming it into a Machine Peeled Pole. Poles are then put through our Steam Drying process, which allows us to get an even penetration and retention of CCA chemical in the Treating process. Poles are Pressure Treated to H5 Hazard Class in accordance with New Zealand Standard NZS3640. Once our Poles have been treated they are stored on the Drip off Pad to allow Fixation to occur which is when the chemical is dry on the wood and no more leaching of chemical can occur.

Here at Roundwood New Zealand we have constructed our own Proof Testing Machine for the sole purpose of being able to Strength Test Construction Poles.

Proof Tested Poles can be tested to verify they meet either High Density (HD) specifications of 450kg/m3 or 52MPa, or an Ultimate Top Load (UTL) Kilo Newton (kN) Rating required for Utility Line Poles.

Use Roundwood New Zealand Machine Strength Tested Poles for

  • Structural Building High Density (HD) specifications
  • Retaining Wall High Density (HD) Engineer specified
  • Artificial Shelter Belt Structures - Horticulture
  • Foundation Piling High Density (HD) Engineer specified
  • Telecommunication Poles Ultimate Top Load (UTL) requirement
  • Power Transmission Poles Ultimate Top Load (UTL) requirement
  • UGLIES (Un-Peeled) Poles for Foundation Piling (HD) requirement

Treatment Process

Our roundwood poles and products are subject to steam drying, which allows us to get an even penetration and retention of CCA chemical in the treating process. Poles are then pressure treated to H5 hazard class in accordance with New Zealand Standards (NZS) NZS3640. Once Poles have been treated they are steam dried to ensure the chemical is locked into the product and is safe to handle.
