PSI System: A

3″ Composite Metal Deck

System “A” consists of load-bearing structural stud (braced) walls with a 3 inch deep metal deck acting as a permanent form to receive a composite concrete slab. Key to the system is the alignment of the vertical studs (@ 24”oc), with the corresponding flutes of the floor deck, thus eliminating the need for load-distribution plates at the top of the stud walls.

Given the span characteristics of the 3 inch metal deck, this system is especially suited for multi-story hotels, dormitories and apartments with stacked bearing walls up to 16 feet apart.
