Open steel flooring is constructed from Load Bearing Flats
in a wide range of depths and thickness. These flats are set
at various pitches by Twisted Transverse Bars, forge welded
to the top surface of the Load Bearing Flats, under 100 tonnes
of pressure and 2000 KVA.
The forge-welded process provides a one piece unit with maximum
resistance to distortion and twisting, allowing the grating
to be extensively cut and shaped without reducing strength
or rigidity. The combination of flat and twisted bar gives
excellent strength to weight ratio, unique slip resistant
qualities and allows the free passage of light and fluids.
The gratings are available with either Plain or Serrated load
bearing bars. Plain pattern brings together all the qualities
of open steel flooring at the lowest cost. Serrated pattern
offers a much improved performance in areas where low traction
conditions are prevalent, and is therefore often used in Offshore
or Sewerage Projects.
when using serrated gratings, the safe load is derived by
multiplying the plain U.D.L. value for your chosen span, by
the relevant U.D.L. Serrated conversion factor.
Gratings are held in standard panels of 6 metre x 1 metre
(nominal), ranging from 20mm up to 60mm deep, in either 3mm
or 5mm flatbars. Other sections can be produced on request.
We offer a full design and fabrication service on all our
gratings, or alternatively stock panels can be supplied direct
from our works.
Gratings can be supplied as, self colour, galvanised, or as
requested by the customer.
Gratings are easily fixed in position from above, using butterfly
style fixing clips. We would normally recommend that a quantity
of 4 clips per meter squared be used. Fixing Type 1 Clips
are stocked in a galvanised finish.
