Boral About

Pentarch is the largest manufacturers of Australian hardwood products and the industry leader in hardwood flooring. The company’s solid hardwood products are manufactured at mills throughout New South Wales.


Pentarch 19mm solid strip flooring is available in One main grade -Standard and Better. Pentarch Timber Flooring meets Australian Standards and uses the aesthetic grading system. Grading is distinguished by selective gum veins, spirals, burls, insect trails and other natural features that give timber floors a unique character, as individual as a signature. Pentarch Timber Flooring is not graded for colour variation or grain patterns as they form part of the natural beauty of timber flooring.

  • The profile consistency across the entire 19mm solid strip flooring range provides mixed board width design options and multi-directional board laying.

  • The tongue and groove design includes a structural secret nail pocket designed to seat boards better.

  • Blackbutt and Spotted Gum have a natural fire resistance. Their fire retarding properties, make them suitable for use in many bushfire prone areas under Australian Standard AS3959.

  • 19mm solid strip flooring can handle foot traffic as soon as it is laid, allowing for other trades on the job before a final sanding and application of the finish.

  • Solid hardwood floors are excellent for asthmatics as they do not harbour dust mites or other allergens.

  • A timber sub-floor gives easy access to the underfloor for plumbing or ducted heating, or to repair wiring.
