The Lapeyre® stair features a unique alternating
tread design which provides greater tread depth
than vertical ladders or ship's ladders. This design
allows comfortable face forward descents at steep
angles. The stair includes close fitting handrails
which provide support and a cushioned central
stringer which virtually eliminates the possibility of
hitting the nosing of a tread.

ALUMINUM STAIRS

The Lapeyre® aluminum alternating tread
stair combines the safety features of our
unique, alternating tread design with the
advantages aluminum has to offer. Aluminum
is ideal for exterior applications and for
applications where weight is a consideration.
The cast aluminum treads are welded to the
central stringer and to the handrails, creating
an all-in-one welded unit.
An optional 3.75" handrail is available for roof
hatch applications.
