Wire Balustrade
A Wire Balustrade is a vertical up stand which protects users of a structure next
to a vertical displacement in between horizontal structure surfaces or on the side of
a stairway. Balustrading is required to adhere to the BCA and be rigid enough to
hold up against applied pressure. Balustrade might have a handrail over.
The Building regulations of Australia Items 3.9.1 and 3.9.2, Volume 2 and
Australian Standard 1170.1 are written to guarantee structure that allows
individuals to move safely in between different levels of the building using ramps
or stairs.
To avoid people from falling, a continuous Wire Balustrade or obstacle should be
supplied alongside any stairway or ramp, any floor, corridor, hallway, terrace,
verandah, mezzanine or course of access to a structure if it is not bounded by any
level or a wall more than 1 m above adjoining floor or completed ground level. It is
very important to keep in mind that the measurement of the height of the Wire
Balustrade or barrier is from the finished floor surface. Finishes such as ceramic
tiles and even carpet can make a significant difference to the finished floor height.
The Height of a Balustrade or Barrier Should Not be Less Than 1m above the floor
of any access course, balcony, landing where it is not bounded by a wall and its
level above the surface area is 1m or more than 4m where an individual has the
ability to fail an open window865mm above the floor of a landing to a stair or
ramp where the Wire Balustrade or other barrier is offered along the inside edge
of the landing and is not even more than 500mm long.
A shift zone may be incorporated where the Wire Balustrade or barrier height
modifications from 865mm on the stair air travel or ramp to 1m at the landing.
To Abide by Requirements of Acceptable Building Practice Stairs Should Not
Have more than 18 risers in a flight of steps to ensure that people work out a
limited variety of steps before a landing is installed so they can rest
even more than 3 winders in a 1/4 landing where the going of the winders to either
1/4 or 1/2 landings could differ from the rest of the air travel nevertheless they
need to be constant within the landing and not varied individually:
a riser opening higher than 125mm
a going less than 240mm for a straight air travel of steps
The maximum slope of a ramp need to not go beyond 1:8 and the floor surface area
need to be non-slip.
Obstacles or Wire Balustrade should be constructed such that a person can not
fall over or through them while at the exact same time limiting a kid crawling
through them. Openings in Wire Balustrade or obstacles need to be constructed so
that any opening does not allow a 125mm round to go through it where for stairs
this space is tested above the nosing line.
A balustrade or obstacle need to be developed to take loading forces in accordance
with AS 1170.1 which requires that a Wire Balustrade or obstacle ought to be
structurally sufficient to withstand a point load of 0.6 kN and an equally distributed
load of 0.4 kN applied inward, outside, or downward on the handrail. These design
loads are meant to guarantee that the barrier is rigid enough to withstand a person
falling versus it without collapsing (point load) and suitably rigid and strong
enough not to collapse should individuals lean against the obstacle (distributed
load).
In weather condition or wetness exposed applications, handrails, posts, newels,
balusters and infil should either be naturally long lasting Class1 or Class2 lumber
species such as black butt, found gum, ironbark, jarrah, merbau, or kwila with any
sapwood present dealt with to H3 standard. Preservative dealt with softwood ought
to be dealt with to H3 requirement or higher and need to comply with AS 1604.
Ideally, the timber must be without any major strength lowering functions and be
straight.
All metal ports including nails, brackets, bolts and screws ought to be a minimum
of hot dipped galvanized or for screws, Course 3 rust resistance as per AS3566.
For coastal environments subject to airborne salts deposition, stainless-steel or
comparable rust resistance metal connections should be used.
All timber-to-timber user interfaces for all joints must have a seal covering of
preservative solution and all joints, ends and surfaces need to be keyed prior to
assembly with a quality solvent based alkaloid primer or stain in accordance with
producer's suggestions. 2 final leading coats of outside paint or stain need to then
be used in accordance with manufacturer's recommendations.
For floors more than 4m above ground, any horizontal aspects within the Wire
Balustrade or obstacle in between 150mm and 760mm above floor have to not
facilitate climbing. To avoid this preferably, the Wire Balustrade needs to have
vertical members spaced no more than the maximum opening or be a strong panel
barrier.
Handrail and Obstacle Heights Must Not be Less Than 1m above the floor access
terrace, path or landing865mm above the nosing of the stair
A change zone could be incorporated where the Wire Balustrade or obstacle
height modifications from 865mm on the stair flight or ramp to 1m at the landing.
Posts are to be spaced maximally at 1.8 m.
Wire have to be stainless steel with a minimum diameter of 3.2 mm.
Optimum wire spacing is 100mm.
Intermediate droppers are to be fitted at a maximum 9oomm in between posts and
secured leading and bottom.
Tensioners are to be put on each strand of wire at each change of direction of 30
degrees or more.
A strong handrail is needed of steel tubing with a minimum diameter of 40mm or
wood as per the Timber framing Code AS 1684.2 1999.

level. It is important to note that the measurement of the height of the balustrade or
barrier is from the finished floor surface area. A balustrade or obstacle have to be
developed to take loading forces in accordance with AS 1170.1 which requires that
a balustrade or obstacle must be structurally sufficient to endure a point load of 0.6
kN and an uniformly dispersed load of 0.4 kN used inward, outward, or downward
on the handrail.
