Stair Riser
The stair riser in this picture are the individual pieces of plywood
with arrows pointing to them and are the parts of the stairs that cover
the vertical distance between each step. The
riser also adds additional support to the front of the
stair tread, if
the riser wasn't there the steps could flex, under a considerable load.
Stair risers can be made out of half-inch plywood, 5/8 plywood or
3/4" plywood. If you're building an outdoor set of stairs you might
choose a 1 x 8 or 2 x 8 depending on your stair design.
Tip if you're building a exterior stairway out
of a material like redwood or cedar you may choose to use this material
for your stair stringers, stair riser's, stair treads and hand rail
system, remember, plywood can delaminate if it gets wet.
