Please note; for orders of 40m2 or less, there is a break pack fee of $80 Northern Beech Sourced from the NSW highlands, Northern Beech is timber mix of a variety of species. Its colour tends towards pale to medium straw, but can contain some yellow hues. Its most dominant features are gum veins and pin holes. This hardwood is of a medium to hard density, and is particularly suitable in domestic settings. Select Grade Select grade timber has the minimum allowable occurrence of natural features such as gum veins and pin holes, with those features it does contain having the minimum allowable dimensions. Prestige Grade Prestige grade combines select grade timber with some relatively low feature standard grade timber. Standard Grade Standard grade timber has a moderate quantity of natural features, with those features having greater allowable dimensions than those found in select grade. Rustic Grade Rustic grade is a combination of standard grade timber and feature grade timber, with some features which are more prominent than those found in feature grade. Feature Grade Feature grade timber has a high quantity of natural features relative to standard grade, such as knots, gum veins, pin holes and even holes through the odd plank, with those features having a greater allowable range of dimensions. Structural Solid Timber Structural solid timber denotes timber that can be used as the primary structural floor. It ranges from 19mm thickness and above. Structural timber must be “top nailed”, meaning the nails go through the top of the plank at a 90 degree angle and into the sub-structure. The head of the nail sits below the surface level of the plank, and the resultant small hole is filled with an appropriate filler. Overlay Solid Timber Overlay Solid timber denotes timber which must be installed over an existing structural floor, such as existing floorboards or a concrete slab. As the Overlay timber is a non-structural floor, it does not require “top nailing”, and can rather be “secret nailed”. This means that the nail is inserted at a 45 degree angle through the tongue of the timber plank along its edge, and into the substrate.
