Maple Stair Treads
Maple usually has a white to light cream color with a haze of red running through it. The grains usually aren't going to be tight, but some of the patterns, the grains in the wood make, can turn almost any staircase into a work of art.
Hard Maple or Sugar Maple definitely fits into the
category of hardwoods and even makes an excellent firewood. Believe it
or not, these are the same trees that different varieties of maple syrup
comes from. Maple can be used for almost every part of the stairway.
Gluing = Great, even though Maple is harder to work with, it still seems to hold up pretty good, when glued together.
Sanding = Moderate, since it's one of the harder woods, it's going to be harder to sand. Remember, to try and avoid over sanding any hardwoods, because you could raise the grain and create a wavy surface.
Staining = Great, this was one of my grandfather's favorites woods to work with and it can be stained in a variety of different colors.
Nailing = Difficult, the harder woods are simply harder to nail and almost impossible to screw through, without pre-drilling holes for your nails or screws.
Wear And Tear = Excellent, Maple will make fantastic stair treads and will require a lot of traffic, before it starts to show heavy signs of wear and tear.
