large decorative planter box fill with white sand

  • Grade: AA-Grade. 1.9m – 8m lengths. W x H <200mm – 500mm.
  • These are big Hardwood timbers made up of Jarrah, Ironbark and other royal Australian hardwood species brought into NZ 30 to 50 years ago. The big and impressive factor is what also hinders the supply ability as new timbers are cost effective to mill at these dimensions, with laminated timber and steel ‘I’ beams etc taking their place.
  • Further, the old trees that can provide 400 x 400 dimension heart quality timber are either protected (hopefully) or non existent in the approved logging areas of Australia. Their lives as wharf structures, bridge bearers or railway structures are over but they are available in rustic form to offer a second, very long life in NZ.
  • Very suitable for large & prominent features. Projects and designs can be easily revolved around a feature piece of this magnitude. As feature entrance pillars, exposed roof trusses, fireplace surrounds or any rustic design where quality and prominence is wanted. Not suited to be highly worked due to density and rarity.
  • Talk to us early in your designs, allow time and usually using several different beams of differing dimensions . For example 300mm x 300mm width requests can be substituted for 340mm x 280mm widths, yet the big impressive style is still successfully achieved.
