Design Information
LEWIS floors are widely applicable in new build construction and renovation. In addition to the standard steel thickness of 0.5 mm, the LEWIS Dovetailed sheeting are also supplied in 0.7 mm. LEWIS Dovetailed sheeting are used for floor thicknesses from 36 mm. In addition to standard (lightweight) fine gravel concrete, the slabs can also be finished with other mortars, such as cementitious and liquid screed mortars. Contact us for constructive data, design tables and advice.

Load bearing construction
Using LEWIS Dovetailed sheeting, it is always necessary to check whether the wooden or steel supporting structure – together with the LEWIS floor – is sufficiently strong and rigid. This check is carried out in accordance with the Eurocodes and the National Annexes. In the table below you will find a safe indication of the load-bearing capacity of a wooden joist with a 50 mm thick LEWIS floor. You can always contact us for advice about your load-bearing structure.
Interconnected (wood-concrete) LEWIS floors
In situations where the wooden beams are not strong enough for a LEWIS floor, LEWIS screw nails can be used. This is how to make an interconnected wood-concrete floor with LEWIS Dovetailed sheeting. Design tables are available on request.
