4.1 TYPES OF STAIRS

Assembled

Assembled stairs show each riser, tread, and stringer as separate elements like assembled wooden stairs.


Figure 4.1 Assembled Stair

Monolithic

Monolithic stairs use the same material for treads, risers, and stringers.


Figure 4.2 Monolithic Stair

Precast

Precast stairs use structural rebar in concrete like a cast-in-place stair would be built on-site.
