WHY USE SILVER BEECH?
Silver beech is sourced from sustainably managed forests and is becoming the favoured wood to replace Rimu as the prime native species. It is excellent as a turnery species, particularly good in brushes and dowels, and excellent for cabinetry. It also is renowned for its steam bending properties and was once widely used for motor-body building. Today, it is useful for brushware and dowels, small turned goods and implements, handles and railings, and furniture.
APPEARANCE AND DESCRIPTION
The colour of silver beech varies with location, age and between the sap and heartwood, but always has a pinkish to red overtone. The dry sapwood is a light pinkish grey, and the heartwood pinkish brown.
Silver beech is non-durable, both for heartwood and sapwood. It is unsuitable for outdoor applications but can be used for interior and indoor furniture applications without the need for further treatment.
