Tuffloor® Steel Flooring
Strong, lightweight, durable and easy to install steel flooring system
Tuffloor is a steel floor framing system designed for strength and ease of installation, and is an easy and economical alternative to timber subfloors. The system is ideal for domestic house construction and extensions, and suits cladding with either tongue and grooved strip flooring, or a wide range of particleboard, and composite products.
It is suitable for commercial and light industrial applications, although you should refer these applications to Stratco to determine allowable spans for these load conditions. Tuffloor is pre-cut to length, eliminating on-site cutting, saving you time and effort.
Brochures & Installation Guides
Suited To Your Project
It is particularly suited for use with reactive soils, and sloping sites, and can be installed in remote locations without the need for cartage of extensive installation infrastructure. Offering economical spanning performance, Stratco Tuffloor is adaptable to a variety of building designs and construction methods.
Economical
All major structural components are made from high tensile steel providing strength and impact resistance. The efficient strength to weight ratio of high tensile steel minimizes the weight of materials needed to be transported to site, saving money in remote locations. With the increased load bearing capacity of the Tuffloor system, smaller sections can be used, contributing to cost efficiency. When this is combined with in-line construction, the total height of the building can be reduced, further saving brick and cladding costs. Keeping project costs under control is always a challenge on any building project and choosing Tuffloor for your project makes a lot of sense.
Versatile
235mm sections allow for 115mm pipe penetrations and toilet bends under the floor, and standard joist spacings compatible with a large variety of flooring materials.
Long Life
The galvanised coating offers long term protection against corrosion. As the subfloor is made from steel it is not subject to twisting or warping. Other benefits include termite protection, mould resistance and elimination of wood rot.

Design Information
Stratco Tuffloor flooring conforms with the following Australian standards:
- AS 4100:1998 Steel Structures.
- AS/NZS 4600:1996 Cold-formed Steel Structures.
- AS/NZS 1170:2002 Structural Design Actions.
- AS 3623:1993 Domestic Metal Framing.
The following design loads are used in the determination of the span tables:
Floor Loads
- 2.0 kPa, live load
- 0.6 kPa, dead load
- 1.8 kN, concentrated load
Roof Loads
- 0.9 kPa tiled roof dead load
- 0.3 kPa steel roof dead load
- 0.25 kPa live load
Wall Loads
- 0.8 kN/m dead load
Design Criteria
The Roof Load Width is the effective width of roof that the bearer is supporting. The diagram below shows a simplified method for determining the Roof Load Width.

All sections are galvanised to Z350 specifications and are rolled out of high tensile material with a minimum yield strength of 450MPa.
Joists
Joist members are to be simply supported between bearers and should be used with bearers of the same depth. Spans for joist spacings less than 450mm should be based on 450mm.
