/GRATING (Stainless Steel Saddle Assemblies)
Metal Deck may
be installed with stainless steel Saddle Assemblies the same as it is
installed with galvanised Saddle Assemblies or as follows with one person.
This is also the method to install Metal Deck where access under the
grating is not possible.
speed drill (electric, pneumatic or battery).
P-3 driver for drill.
1/4" High speed steel drill bits.
Artline pen or similar.
Steel Saddle Assemblies. (Part No: 12-210).
Consisting of :
M6x50mm Pan Head, Phillips drive S/S metal thread.
1 pce S/S universal saddle.
1 pce S/S 6mm Nyloc locking nut. (Optional).
- Insert the P-3
driver into the drill chuck and tighten.
- Lay the sheets
of Metal Deck in the desired positions ensuring that gaps are equal
and the walkway or ramp is completely protected.
- Mark the correct
position for the holes on the surface of each sheet of Metal Deck.
The optimum position for holes is centrally between the transverse
and longditudinal grating bars. Try to mark the surface so that the
holes will be more than 40mm from any edges of the Metal Deck.
- Mark the top
surface of the grating along the edges of each piece of Metal Deck
so they can be returned to the same place after drilling.
- Turn each sheet
over and mark the underside with a number and an arrow so that the
correct sheet is returned to the correct position, facing the correct
way after drilling.
- Measure the
distance of each mark from the edges and, using these measurements,
make reciprocal marks on the underside of the Metal Deck.
- Using the hammer
and centre punch, make an indent on the marks which are or the underside
of each sheet.
- Drill 1/4" holes
using the indents to direct the drill bit. Always drill from the underside
through to the antislip surface.
- Insert the metal
threads into the recently drilled holes so that the head is on the
- Screw the pre-threaded
saddles on to the metal threads protruding from the underside of the
Metal Deck. (3 - 4 turns will suffice).
- Return the
Metal Deck to the original positions and swivel each saddle around
until they fit through the holes in the grating.
- When all saddles
of the first sheet are through the grating and the sheet is in its
original position, stand on the Metal Deck and insert the P-3 driver
(on the drill) into the head of one of the metal threads.
- Reach some
fingers through the grating and rotate the saddle 90 degrees so that
it will lock up under the grating.
- While holding
the saddle in this position, activate the drill and slowly tighten
the metal thread into the saddle.
- Continue tightening
the metal thread until the saddle assembly and corner of Metal Deck
are secure. (Approx. 5ft/lb).
- Repeat procedures
12-15 for the other metal thread / threads on the first sheet of Metal
Deck and continue onto the next sheet.
- To avoid any
accidents, block traffic flow through areas being worked on.
