Hi all,
I need to build a few ladder type stair cases outdoors. It will be to allow stairs over rocks as well as one set rising approximately 3 .metres. The 3 metre one will be immersed in water bottom 10cm or so whilst tide i high. The house is build on a steep block and the path leads to water.
My question though is regarding the wood. Should I use 100mm x 50mm or 100m x 25mm for the sides of the ladder stairs?
I plan to use H4 Treated Pine for all the structure and stairs. The small stairs that I use wound need to worry about the water.
Thanks
