After almost 35 years in use, the classic Holorib profile, only modified from its original form to suit metric cover width, still provides economic solutions that allow a combination of shallow construction and high fire resistance values in suspended concrete slabs with or without fully composite construction.

The re-entrant shape has tremendous structural integrity and provides the easiest of installation procedures on both simple and complex layouts.

The UK's most widely specified profile.

Some technical benefits of Holorib:

• Best concrete compression block for flexural resistance
• Deep concrete section/high steel content for best vertical/longitudinal shear resistance
• Shape of troughs allows a greater number of shear studs and optimum shear stud performance
• Only decking type not requiring fire stops over support beams for fire resistance periods up to 2 hours
• Strongest load carrying performance
• Shallowest slabs for providing 2 hours fire resistance
• Embossments in tops of ribs ensure the most effective shear bond characteristics
• Allows construction of most dense slabs for best sound insulation
• Greatest flexibility for low cost, stronger service/ceiling suspension
• High composite inertia minimises service deflection
