Lets not make it easy for them... Ground anchor your furniture securely with a pair of Simpson Strong Ties. Supplied with appropriate expansion bolts - long for concrete or short for flags. Determined thieves may find a way around anything but we include sheer nuts that will break off when tight, leaving only a tapered cone that's somewhat tricky to remove. Everything is made from rust resistant steel.
A unique wood like 3 Seater Garden Bench made out of British Recycled Plastic - synthetic wood. Looks and feels like wood, but behaves like plastic. No splinters for little fingers, no painting needed, does not rot. When all the wooden benches have rotted away this bench will still be looking good. Entirely maintenance free outdoor seating. Delivered on a pallet fully assembled.
A traditional Picnic Table that looks and feels like wood but behaves like plastic. No rot, no painting, no maintenance. Made from 100% British sourced recycled plastic (crushed CD cases and old coat hangers). UV protected against fading in direct sunlight. Will still be looking good when all the wooden picnic tables have rotted away.
