| Here's a picture of four stair stringers
with upper stair
stringers still laying on the cement floor. The black arrows are pointing to
the stair stringers which are the main supports for this type of
stairway.
Often stair stringers are referred to as carriages for stair horses it
all depends on what part of the country you're from.
The stair stringer needs to be fastened correctly at both the upper and
lower points so the structural load is transferred correctly. If the
stair stringers are not fastened correctly this could result in a safety
hazard and excesses squeaking as we walk up and down the stairs.
Stair stringers should be made from a structurally sound piece of
lumber.
In this picture the stringers are number one grade 2 x 14 Douglas Fir.
When selecting stair stringers material at the lumber yard
try to avoid big knots and large cracks. Big knots can
weaken stringers and break under extreme loads. |
