We used new French oak railway sleepers (250mm x 125mm profile) to create these sturdy steps on a raised patio. We decided to apply some 'Osmo UV protection oil 420 clear satin-matt' on the freshly sanded oak. It's very expensive (£56 for a 2.5 litre can) but it prevents the oak from going a silver grey, and keeps the golden oak colour. Six months on, it's still got its original colour.
We fixed the railway sleepers together with Timberlok railway sleeper screws http://www.railwaysleepers.com/railway-sleepers/railway-sleeper-fixings/timberlok-railway-sleeper-screws
RAILWAY SLEEPERS USED
New oak railway sleepers, 2.6m x 250mm x 125mm
A wonderful raised patio in progress. The railway sleeper steps have a chunky, sturdy appeal that suggest they will be there for decades, and simply complements the rural open fields they overlook.
