Concrete sleepers are a great way to build a set of stairs they are easy to install and look good. It is best to use the woograin sleepers as your tread because the pattern is flat for walking on and will also previde a non slip surface, For the riser you can use another pattern sleeper or stick to the same as your tread it is a good idea to use a different colour riser it looks great while also makes the step more vissable and less of a trip hazard.
