HAMBRO PRODUCT

Hambro is a composite floor joist system for elevated floor construction.
The system consists of hybrid concrete/steel T-beams running in one direction and an integrated continuous slab in the other. The bottom chord acts as a tension member in the concreting stage and during the service life of the floor.

The web system tying top and bottom chords together consists of bent rods and resists vertical shear in a conventional truss manner. The patented 13 gauge top chord acts as a compression member during the non-composite stage.

In the composite stage, the top chord is embedded in the concrete and functions as a continuous shear connector. The concrete slab is reinforced with welding wire mesh. The top chord functions as a high chair, developing negative moment capacity in the concrete slab, which behaves as a continuous one-way reinforced slab.

Hambro D500
Composite steel joists and a poured concrete slab, create tension and compression during the pour.

Advantages of this are:

1. Rigid concrete floor system
2. Carpentry installation
3. U/L Ratings
4. Value engineering
5. Spacious duct openings
