The table below give the safe Uniformly Distributed Loads in kN/m for mild steel gratings with plain load bearing bars.
For gratings with serrated edge load bearings bars the tabulated loads should be multiplied by 0.75 for 25 mm and
30 mm deep sections and 0.80 for 35 mm and over deep sections.
The loads have been calculated to a maximum stress of 165 N/mm2 and deflections are limited to within 1/200th of the
span or 10 mm whichever is the lesser.

8. Mild Steel & Stainless Steel Floor Plate
Durbar raised pattern non-slip mild steel solid floor plate.
This plate may be used for trench covers, platforms, stair landings and
stair treads. The raised leaf pattern, having no enclosures, provides
increased non-slip surface to give firm grip in all directions. For
particularly slippery conditions a carborundum surface finish is
available. Plates of this type are self draining and readily cleaned,
therefore minimising corrosion and ensuring longer life.
Trench covers, which are to be readily removed, are holed for and
supplied complete with standard lifting keys. Where necessary, plates
are cut to clear pipework or other obstructions and are countersunk
drilled for securing to steelwork with fixing screws.
PGP HEAVY PATTERN
Mild Steel Floor Plate is available in 4.5, 6.0, 8.0,10.0 and 12.5mm
base thickness. Primer Painted or Galvanised.
In Stainless Steel available in grades 304L or 316L.
Aluminium Tread Plate
Aluminium tread plate, designed primarily for flooring applications
provides a non-slip, easy clean, hard wearing surface, which has
found extensive use in Industrial, Marine and Transport fields.
Tread plate comes in three popular patterns to suit various
conditions of service and personal preferences. Thickness for
thickness, in a particular material, the load bearing characteristics
of the three patterns, are not significantly different, but a choice
does accommodate factors such as pedestrian comfort, durability,
and aesthetic consideration. Applications vary from kick plates to
loading ramps, from factory flooring and stairtreads to
protective facias. Supplied self-colour.

12. Companion Step or Ship Type Ladders
This type of ladder provides an improved
means of access over the normal single
run ladder when space is available.
The 65 degree to 75 degree slope is
easier to negotiate than a vertical
or near vertical ladder.
We recommend that the maximum
vertical rise should not exceed
3000mm and the width between
stringers should preferably be between
limits of 450mm and 550mm.
It should be noted that 250mm
minimum foot space should be allowed
from the nose of treads to the wall,
platform face or other obstruction, see
illustration. A top tread should be
provided at floor level, or the platform
can be arranged to run over, but the
minimum foot space should still be
maintained. Handrails are necessary on
this type of ladder and should be
provided on both sides without
exception.
Chart giving useful
recommendations
for staircases
This chart gives preferred rise/go dimensions see section
coloured yellow for any given rake of staircase or
ladder and is based on our recommended formula:
Twice the rise plus the go = not less than 570mm
nor more than 640mm (550 to 700).
‘Go’ is the term used for the horizontal
dimension of a stair or tread.
‘Rise’ is the vertical dimension.
‘Overlap’ is the amount the nosing
of one tread overlaps the one
below (minimum16mm).
Example: A single flight stair has a rise
of 2600mm and has to comply with a
minimum tread ‘go’ of 250mm and a
maximum rise of 190mm. From the chart
below we see with a ‘go’ of 250mm an
acceptable rise will be about 185mm.
This will give 14 equal rises. The stair
will thus have an angle of rake pitch
of 36º 36’ and will fall within the limits
required for this type of stair. Also the
aggregate of twice the rise plus the go
equals 620mm, close to the optimum
recommended in BS 5395 Part 1.

These bases are
suitable for mild steel

to resist a maximum
horizontal force of
0.36 kN/m at design

Bases for Solid Standards Type ’S’
Suitable for 32mm and
38mm dia. standards
required to resist a
maximum horizontal
force of 0.36 kN/m
at design load.
Heavy Duty Bases Type ’HS’
Suitable for both Solid and Tubular Standards
required to resist a maximum horizontal force
of 0.74 kN/m at design level.
High Tensile Bolts should be used.
Types with suffix 'C' are designed for fixing to
concrete at an optimum spacing of 1.25m

25 N/mm .
Types with a suffix 'S' are designed for fixing
to steelwork at spacings of up to 1.8m.
Designers should ensure that the adjacent
construction acting as support for handrails
and balustrades is of adequate strength and
stability to sustain all applied loads safely
without excessive strain, deflection or
distortion.
Note: Bases are drilled 19mm dia. holes for M16 bolts. Non standard drilling can be accommodated and bolts supplied on request.
