Tuin is a Dutch garden product company well established in Holland & the UK. This Deluxe Workbench is made from the highest quality timber, kiln dried & slow grown from sustainable sources FSC certified. This process results in a tight grain with a resistance to rot & movement. This product has been manufactured using pressure treatment. This process is often referred to as tanalising & is far superior to any process where wood is only dipped or has a base coat applied. Tanalising involves impregnation with Tanalith E (environmentally friendly) wood preservative, under controlled conditions in a vacuum pressure timber impregnation plant. When impregnated into the timber the chemicals become locked into the timber & cannot be removed. Occasionally the treatment leaves a green/blue residue on the surface which can be simply brushed off. This is a feature that occurs but is not considered a blemish. The residue is not harmful. The time taken for the residue to dissipate will vary with weather conditions. The treatment described above provides a long service life & long term protection from fungal, insect attack & rot. The luxury Workbench & Integrated Zinc Sink Tank by Tuin is a fantastic product that will be perfect for your shed & greenhouse. The luxury Workbench features a spacious worktop area with a lower level shelf stretching the width of the table. A sink tank is also integrated to make this an ideal product for any greenhouse. Please note the sink is not water tight & designed as an aid in repotting.
