Radiata Pine vs Gum

 

Why are Radiata pine poles better than gum poles?

Gum (Eucalyptus) is a dense, hard timber species. Since gum timber is marginally stronger than pine, people think this provides a more durable pole, but they are mistaken.

Gum has less sapwood and more heartwood when compared to Radiata pine. But it is the sapwood that gives the pole its structural strength and durability. The sapwood is the part of the pole that absorbs the protective treatment chemicals, so less sapwood means less treatment is absorbed. The heartwood is untreatable. Less sapwood also means less depth for the treatment to penetrate, which means less protection. With less treated sapwood there is more chance of cracking and exposing the untreated heartwood to the elements. With the correct seasoning and treatment methods, Radiata pine poles are not only durable, but they are strong too.

What makes Woodline poles the right choice?
  • The right species selection

Radiata pine is known for its structural strength. Its sapwood allows deeper penetration of the chemicals during treatment processes, enhancing the product’s longevity. Woodline poles predominantly use the slow-grown Pinus Radiatta, known for its exceptional strength, durability and quality.

  • The right peeling process

For strong poles, the diameter of the log, before peeling, needs to be close to the size class of the intended finished pole product. Over-peeling a log strips away its strong sapwood band. Woodline eliminates the potential for over-peeling by keeping and grading a wide variety of log diameters, while ensuring the proper control of the peeling process.

  • The right seasoning process

Freshly-cut logs hold as much as 95% moisture content. However, 25% moisture content is required for poles to undergo the correct treatment methods to perform optimally. This reduction in moisture content is achieved through proper seasoning. Every inch (25mm) of pole diameter requires one month seasoning. (e.g. 4 inch diameter = 4 months’ seasoning) Woodline’s extensive resources and kiln ensures no pole leaves the yard without the correct seasoning.

  • The right treatment process

The correct chemical treatment (retention and penetration) of the pole ensures its longevity. Retention is the dosage or amount of treatment supplied to the pole, while penetration is how deep the treatment enters the diameter of the pole. Insufficient dosage or shallow penetration leaves the pole vulnerable to infestation and the elements. By using Radiata pine and adhering to proper procedures, Woodline ensures correct dosage and ample penetration of the sapwood, resulting in poles known for their quality, durability and longevity.

Rounded Pine

Cylindrically machined poles, commonly used for playground structures, building projects and guard-rail posts and the construction of modular log homes.

Post and Rail Fencing

Using cylindrical poles, drilled, to customer requirements for number of rails, and machined, with domed tops, this product offers an easy-to-erect type fencing with an attractive ranch style effect. Also available are corner posts, end posts, line posts and un-drilled bollards.

Utility Poles
Telephone Poles (for overhead telecommunication lines)

Manufactured according to SANS 753, unless otherwise specified, poles ranging from 6.0m to 9.0m in length are prepared to customer requirements, prior to treatment. Poles can be pre-drilled, gained and labelled as required.

Transmission Poles (for overhead power lines)

Prepared according to SANS 753, or specification as required by the customer, poles of up to 14m can be produced. Diameters are determined by strength class required. Whether determined by the top diameter, as in South Africa, or by international specifications, where Theoretical Ground Line usually determines the strength class, Woodline's customers have the assurance that the poles are manufactured according to exacting specifications.
