When specifying timber decking for commercial projects it’s easy to stay with the standards; not realising there are new and innovative decking ideas out there.

This London balcony project was approx. 100 sqm and comprised of 144mm Kebony Magnet decking over pedestals. With the same Kebony Radiata in 68mm width as Exterpark Magnet Cladding. Once the decking was installed it was oiled with Owatrol Aquadecks to provide a matt finish enhancing the Kebony’s natural beauty.

Exterpark Magnet is a revolution in screwless decking. It’s fast, reliable and simple to use, gone are the fiddly clips and screws. No countersinking and what you’re left with is by far the most efficient system on the market.

Karl Harrison said, “The boards remain completely accessible after installation, simply pop up any board when you need to gain access underneath the surface”.

The system comprises of a pedestal, an aluminium joist and the decking. Once the pedestals are laid in line to the same elevation the joist is laid on top and the decking simply clicks into place…


This system allows the flexibility to create decking platforms with a very low elevation, even as low as 43mm. A 5mm shim or packer, low height joist at 17mm and the decking at 21mm nominal; is by far the lowest system on the market.

Exterpark decking materials were born in 1984, a simple clipped system called “Classic” quickly copied by the masses but nevertheless invented at Exterpark. This system quickly evolved into the first patented decking system in the world which hid the side fixing clips which were known as the Exterpark “Plus” decking system. Magnet is far superior to these, no stainless clips nor screws… only the Magnet clips making it the fastest decking to install on the market.

The additional benefits are vast but the most important is that this system can be used for cladding too. The same profile, clips, aluminium joists and exactly the same method of installation.

Hundreds of thousands of square metres of Exterpark decking has been installed all over Europe, Middle East and is now rapidly travelling around the word and sure to be the Go-To decking system specified for all decking terraces.
