Floor and Roof Systems

Structural-steel framing provides designers with a wide selection of economical systems for floor and roof construction. Steel framing can achieve longer spans more efficiently than other types of construction. This minimizes the number of columns and footings thereby increasing speed of erection. Longer spans also provide more flexibility for interior-space planning.
Another advantage of steel construction is its ability to readily accommodate future structural modifications, such as openings for tenants stairs and changes for heavier floor loadings.
When reinforcement of existing steel structures is required, it can be accomplished by such measures as addition of framing members connected to existing members and field welding of additional steel plates to strengthen existing members.

FLOOR DECK

The most common types of floor-deck systems currently used with structural steel construction are concrete fill on metal deck, precast-concrete planks, and cast-in-place concrete slabs.
