Argentinean Hard Woods

Ranch Driveway Gates

In Argentina we have one of the hardest and longest lasting (without treatment) hardwoods in the world (see details at the bottom table). Between the most used woods that grow in the north forest region of Argentina we have Quebracho Colorado & Anchico. These woods are not only hard but also very good looking.

Quebracho Colorado

Anchico

Quebracho name comes from “quiebra hacha” witch means “axe breaker”, because of its hardness. That is why its used for railroad crossties, heavy construction, fence posts, ranch gates, corral gates, fencing and poles.

Argentinean Hard Woods for Gates

The scientific name of Quebracho Colorado is Schinopsis Balansae. Its heartwood color is light red, deepening to brick red and the aspect uniform or with black streaks (see picture). The luster is low to medium and the texture fine and uniform. It has no knots, no splinters, surface stays smooth & resists damage.

It is one of the most durable woods in the world. Specially appreciated for naval construction because of its water resistant incorruptible characteristics.

It is also very difficult to work, especially when dry, but takes a high natural polish. Heartwood contains 20 to 30% tannin.

Features

  • Durability (fungi, insects. Not painted): >30 years
  • Hardness Janka: 2.470 lbs

Anchico

Anchico

Anchico is also known as Hard Tamarindo and its scientific name is Piptadenia Rigida.
