» GATE CONSTRUCTION INFORMATION
1.1
Gates shall be constructed in accordance with the provisions given for the
appropriate gate type listed.
1.2
Gates shall be designed, constructed and installed to not fall over more than
45 degrees from the vertical plane, when a gate is detached from the
supporting hardware.
1.3
Gates shall have smooth bottom edges, with vertical bottom edged
protrusions not exceeding 12.7 mm when other than the exceptions listed in
ASTM F2200.
1.4
The minimum height for barbed tape shall not be less than 2.44 m above
grade and for barbed wire shall not be less than 1.83 m above grade.
1.5
An existing gate latch shall be disabled when a manually operated gate is
retrofitted with a powered gate operator.
1.6
A gate latch shall not be installed on an automatically operated gate.
1.7
Protrusions shall not be permitted on any gate, refer to ASTM F2200 for
Exceptions.
1.8
Gates shall be designed, constructed and installed such that their movement
shall not be initiated by gravity when an automatic operator is disconnected.

GENERAL REQUIREMENTS
2.
SPECIFIC APPLICATIONS
2.1
Any non-automated gate that is to be automated shall be upgraded to
conform to the provisions of this specification.
2.2
This specification shall not apply to gates generally used for pedestrian
access and to vehicular gates not to be automated.
2.3
Any existing automated gate, when the operator requires replacement,
shall be upgraded to conform to the provisions of this specification in effect
at that time.
3.
VEHICULAR HORIZONTAL SLIDE GATES
3.1
The following provisions shall apply to Residential I, Commercial I and
Commercial II vehicular horizontal slide gates:
3.1.1 All weight bearing exposed rollers 2.44 m, or less, above grade shall be
guarded or covered.
3.1.2 All openings located between 1.22 m and 1.83 m above grade shall be
designed, guarded or screened to prevent a
102 mm diameter sphere from passing through the openings anywhere in
the gate, and in that portion of the adjacent fence that covers in the open
position.
3.1.3 A gap, measured in the horizontal plane parallel to the roadway, between a
fixed stationary object nearest the roadway, (such as a gate support post)
and the gate frame when the gate is in either the fully open position or the
fully closed position, shall not exceed 57 mm, refer to ASTM F2200 for
Exception.
3.1.4 Positive stops shall be required to limit travel to the designed fully open and
fully closed positions. These stops shall be installed at either the top of the
gate, or at the bottom of the gate where such stops shall horizontally or
vertically project no more than is required to perform their intended
function.
3.1.5 All gates shall be designed with sufficient lateral stability to assure that the
gate will enter a receiver guide, refer to ASTM F2200 for panel types.
3.2
The following provisions shall apply to Class IV vehicular horizontal slide
gates:
3.2.1 All weight bearing exposed rollers 2.44 m, or less, above ground shall be
guarded or covered.
3.2.2 Positive stops shall be required to limit travel to the designed fully open and
fully closed positions. These stops shall be installed at either the top of the
gate, or at the bottom of the gate where such stops shall horizontally or
vertically project no more than is required to perform their intended
function.
4.
VEHICULAR HORIZONTAL SWING GATES
4.1
The following provisions shall apply to Residential I, Commercial I and
Commercial II vehicular horizontal swing gates:
4.1.1 Gates shall be designed, constructed and installed so as not to create an
entrapment area between the gate and the supporting structure or other
fixed object when the gate moves toward the fully open position, subject to
the provisions in the 4.1.1.1 and 4.1.1.2.
4.1.1.1 The width of an object (such as a wall, pillar or column) covered by a swing
gate when in the open position shall not exceed 102 mm, measured from
the centerline of the pivot point of the gate, refer to ASTM F2200 for
exception.
4.1.1.2 Except for the zone specified in Section 4.1.1.1, the distance between a
fixed object such as a wall, pillar or column, and a swing gate when in the
open position shall not be less than 406 mm, refer to ASTM F2200 for
exception.
4.2
Class IV vehicular horizontal swing gates shall be designed, constructed and
installed in accordance with security related parameters specific to the
application in question.
Vehicular gates should be installed in accordance with local standards.
