Low Floor to FLoor Heights with Structural Steel

The Combined Advantages of Structural Steel and Flat Plate Concrete

Mid to high-rise residential structures have traditionally used a cast-in-place reinforced concrete structural system which offers such benefits as low floor to floor height and fireproof construction. With similar benefits, low to mid-rise buildings often utilize bearing wall systems supporting precast slabs. These structural systems are time consuming, weather sensitive and labor intensive.

Girder-Slab Technologies, LLC set out to develop a more efficient structural steel based framing system for mid and high-rise residential construction.

Utilizing proven materials that have long been used by the construction industry, the GIRDER-SLAB® system provides a cost effective low floor to floor height solution for mid and high-rise residential construction.

The GIRDER-SLAB® system in combination with a structural steel frame offers a complete steel and concrete superstructure. It is ideal for use in mid to high-rise residential structures such as hotels, student housing, apartments, senior housing and condominiums.

The GIRDER-SLAB® system greatly improves construction operations and the ability to meet critical deadlines. Unlike cast-in-place concrete structures, the GIRDER-SLAB® system uses off site prefabricated components that are quickly erected on site by one trade even in cold weather (Ironworkers).
