Lewis sheets are rolled, self-supporting, 16 mm deep, dovetailed profile steel reinforcement sheets which are used for shuttering and reinforcing lightweight concrete floors of limited thickness on timber or steel floor framing.

Features and benefits:

Simple to use due to the special rolled profile.
Can be laid directly onto floor joists or steel beams. Timber flooring may be omitted, resulting in savings on floor height and weight.
Fire resistance ratings of 60, 90 and 120 minutes.
Airborne and impact sound transmission values to Building Regulations (England and Wales), Approved Document E.
Increased strength and rigidity of the interconnected floor system results in an extra load-bearing capacity of up to 30% for the floor as a whole.
Water-resistant structural flooring.
The profile allows air circulation essential for timber preservation.
Total floor thickness as low as 36 mm, acoustic floors 50 mm.
High load-bearing capacity combined with a low dead load of 0.9 kN/m² (at 50 mm).
