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.
