Will I need skilled trades and specialist tools to install Hambro Floor Systems?
The ease and speed of installing the Hambro floor system eliminates the need for skilled trades. Few tools are also needed to install Hambro, but be sure to have enough of the proper equipment available to keep all employees working. Plan to have:
1. Sledge hammer
2. Circular power saw
3. Rolling scaffold for Rollbar installation, if required
4. 4” rigid metal pipe for levering tight bars in and out, if required
5. Form oil and applicator for plywood

Is Hambro suitable for my construction project?
The design flexibility of the Hambro system satisfies the needs of any type of construction and has been used successfully in single-family detached houses, multi-storied residential complexes and commercial buildings.

Why is the Hambro Floor system better than a concrete floor?
The system is faster, stronger and easier to install. Hambro offers solid, reliable elevated slabs supported by proven floor joists. A composite Hambro floor is also significantly lighter than a concrete slab suspended floor; this is safer in extreme stress situations such as an earthquake. During an earthquake a Hambro floor provides strength with flexibility, but also has less weight to collapse, crushing the floor below

How long does it take a Hambro floor to be able to be used after the concrete pour?
The rollbars and plywood forms can be removed, once concrete has reached a curing strength of 1,000 psi. This will usually occur within 24 hours. At this point the floor is already strong enough to walk on and work from.

What fire protection do Hambro Floor Systems offer?
Fire resistant rating of up to 3 hours is easily achieved with the Hambro Composite Floor System by the installation of a gypsum board ceiling directly under the joists. Hambro floors are composed of steel and concrete; both materials are non-combustible and perform very well in independent fire testing scenarios.

What are the acoustical properties of the floor system?
The Hambro system has a "SOUND TRANSMISSION CLASS" of 57 or IIC 30. STC is a rating that assigns a numerical value to the sound insulation provided by a partition separating rooms or areas. The rating is designed to match subjective impressions of the sound insulation provided against the sounds of speech, music, television, office machines and similar sources of airborne noise that are characteristic of offices and dwellings.

Can you help me understand the “Terminology” of the Hambro system?
