Description

Powdertech Wood Finish (PWF™) was formulated by Powdertech to match the natural variations in colour, grain density and grain pattern of wood. Wood has an instinctive appeal as a building material, associated with the natural world and its warmth and texture.


Features and Benefits:

  • Combines the strength and longevity of metal with the look of natural wood.
  • No pattern repeat - no two coated pieces ever look exactly the same.
  • Can be applied to most metallic substrates including aluminium, galvanized.
  • steel, cast metals and stainless steel.
  • Excellent abrasion resistance.
  • Good weather resistance and colour stability.
  • Low maintenance - unlike wood.
  • Adapts to curved surfaces such as columns and posts.
  • Can be cut and drilled for fabrication.
  • There are 35 standard colours in smooth or texture finishes.
  • PWF Roughwood introduces the textured feel of wood.
  • Applied worldwide since 2000.
  • Resistance to boiling water, no blistering and no loss of adhesion.
  • Cylindrical mandrel bending, tested to ISO 1519, 5 mm mandrel, no cracking or detachment.
