Girder-Slab® System Technology

This patented, but not proprietary, Assembled-In-Place technology is the first ever to use precast slabs with an integral steel girder to form a monolithic structural slab assembly. The Girder-Slab® System consists of an interior girder (known as an open-web dissymmetric beam or D-Beam®) supporting precast prestressed hollow core slabs on its bottom flange. Upon grouting, the Girder-Slab System develops composite action enabling it to support residential live loads. Grouting is easily achieved after slabs are set in place. The Girder-Slab System affords users advantages never before available with cast-in-place concrete superstructures. It is lightweight and offers rapid construction and assembly.

Girder-Slab® System Application

The Girder-Slab System in combination with a structural steel frame offers a complete steel and concrete superstructure. It is slated for use in mid to high-rise residential structures such as hotels, apartments and condominiums. There are two basic D-Beam® Girder sections available for use with an 8" thick precast slab. The DB-8 provides an 8" thick slab assembly, while the DB-9 is designed for use with a 2" concrete topping resulting in a 10" thick slab. Precast slabs generally span as long as 28'-0". The Girder-Slab System is rated for use in high-rise buildings when constructed in accordance with Underwriters Laboratories Inc. Floor-Ceiling Design K912. The Girder-Slab System greatly improves construction operations and the ability to meet critical deadlines.

Girder-Slab® System Availability

The application and use of the Girder-Slab System technology requires design by your registered professional engineer or architect. The Girder-Slab System Design-Guide provides all required engineering information and is available for use by industry professionals.

The Girder-Slab System and D-Beam® Girder are distributed and assembled solely by steel contractors authorized by Girder-Slab Technologies LLC of NJ, the exclusive Distributor Representative in North America.
