In addition to the extensive range of building shell products offered by voestalpine Metsec, we also offer a comprehensive range of mezzanine floors systems including a oversail system and an inset system to allow for the quick and easy erection of additional internal floor space. Mezzanine floor systems can be installed either as part of the initial construction of the building or as a subsequent addition when additional space is required in an existing structure.

The performance of the systems have been validated by a comprehensive test programme carried out by the Department of Mechanical and Aerospace Engineering at The University of Strathclyde.
Adequate torsional restraint is provided by 38mm minimum thickness flooring grade particle board.
This must be fixed to the top flange of the C-sections using appropriate self-drilling, self-tapping screws at a spacing not greater than 1150mm along the span.
Tie bars must be provided at mid span position as illustrated on Mezzanine Floor Tie Bars
All fixing bolts must be M16 diameter, grade 8.8 complete with washer under head and nut. Double span load capacities are based on the consideration of a uniformly distributed load on both spans or on one span only.
Note: the additional consideration of one span loaded is appropriate to this type of floor.
The Metsec oversail floor beam system, designed for use without cleats offers maximum economy. The direct connection of C-sections to primary members may reduce component and installation cost. The performance of C-sections used in this system is related to the length of C-section directly sitting on the main support beam known as the bearing length and should be a minimum of 65mm.
Oversail without cleat connection between C-section secondary beams and hot rolled primary beam
The Metsec oversail floor beam system should be considered where there are no restrictions as to the finished height or depth of the mezzanine floor construction.
Oversail/top cleat connection between C-section secondary beams and hot rolled primary beam
For single and double span arrangements, the maximum allowable overhang should be limited to span/8 with cleats.

Mezzanine floors that require the maximum use of available headroom should be designed using the Metsec inset floor beam system.
In this system, C-sections are connected within the framework of primary members thus keeping the overall depth to a minimum.
