Mezzanine Floor Beams
Hi-Span C-Channels are a comprehensive range of channels for a diversity of
applications. Primarily for use within mezzanine floors, C-Channels can also
be applied in many other circumstances such as door framing, roof trimming,
window trimming, brickwork restraints, parapet rails and side rails.
The mezzanine floor beam depths of 127, 170, 205, 220, 270, and 290mm are
all catered for within the range, 
together with channel depths of 150, 170, and
205mm, which are fully compatible with our 'Z' purlin and
rail sections. While mezzanine floor beams are normally
punched with 18 diameter holes as standard, 14
diameter holes are also available in these sections,
together with the option of counterformed holes.
Restraint Requirements
As the bottom flange of the C-Channel is usually unrestrained we recommend that a
Hi-Span tubular sag rod is fitted. Where possible the channel should face toe to toe with
the restraint situated in the lower gauge line holes.
Floor Cleats
When Hi-Span C-Channels are used as mezzanine floor beams the MFB cleats should
be used at the supports. The cleats are manufactured from a thicker material than the
trimmer cleats to support the higher shear loads associated with floors. When a double
span system is used, hot rolled cleats are needed in order to support the web of the channel. Fixing directly through the bottom flange of the channel to the supporting member is not recommended.
Parapet Channels
Many buildings are designed to incorporate a parapet to the perimeter to hide the ridge from
view. The parapet has a horizontal coping which can require fixing to the internal
face, external face and over the top of the parapet. Hi-Span C-Channels are capable of fulfilling
all of this criteria. They come in a range of depths to suit practically all parapet dimensions.
