Tuindeco imports (garden) timber types from different parts of the world, as we are always trying to find the best quality. Certification and hallmarks for garden timber means a lot to Tuindeco, as it ensuries quality. Wood, however, remains a natural product, and various elements can strongly affect quality. In below table some points of interest are listed for purchasing garden timber.
The nett dimensions of wood are very important. A 2 mm difference (such as a 17 mm board compared to a 15 mm board) would typically result in a 13% price difference. Often this price difference cannot be traced, so you pay too much for thinner wood.
- Some manufacturers provide a wax layer on the wood. This will add value to the product to the extent that a higher price would be justified (price difference of about 5% is customary). A wax treatment is also life extending.
- Square posts and girder timber should always be sawn off-centre ( centre in the post outer area). Centered core posts of girders are more likely to twist and get shrinking cracks.
- To ensure you have purchased correct pressure impregnated timber, check the presence of a KOMO certificate. KOMO can mostly be identified on the barcode sticker of the manufacturer’s leaflet. The KOMO number is of importance in this.
- The number of boards and supporting slats, the timber dimensions and the processing method are frequently used tricks to economise on products.
- Bolted joints are stronger and longer lasting than nailed joints. Please note that so-called ‘screw nails’ are not to be used. You can recognise these by the unusual heads and the scarcely threaded shafts
- Poor quality planing of items may well signify a less accuracy and selection grade.
