General comment AlphaRiser is a unique Riser Floor system that is integrated with the structural floor slab to protect the riser void and MEP services of services to pass through. The system is made from a steel frame with GRP composite joists and grating to reduce weight and simplify cutting for MEP penetrations, which eliminates the need for hot works permits.
Designed to accommodate either cast-in or retro-fit applications, AlphaRiser can be installed in conjunction with multiple methods of construction, from steel frame, cast concrete floors, pre-cast slabs etc. A significant benefit is the ease of adjustment in the joist positions to accommodate the positioning of MEP services. This means that risers can be procured and installed ahead of final MEP design being set, saving time and money later in the project.
AlphaRiser FR is a unique solution which creates effective horizontal fire-stopping and has been tested for effectiveness by a third party accredited test house to BS EN1366 pt 3.
