Gate Construction Information

Vehicular gates should be installed in accordance with ASTM F2200: Standard Specification for Automated Vehicular Gate Construction. For a copy,
contact ASTM directly at 610-832-9585 or www.astm.org.
1. General Requirements
1.1 Gates shall be constructed in accordance with the provisions
given for the appropriate gate type listed, refer to ASTM F2200
for additional gate types.
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 0.50 inches (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 8
feet (2.44 m) above grade and for barbed wire shall not be
less than 6 feet (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, in accordance with the
following.
1.8.1 Vehicular vertical lift gate. Shall be restrained from movement
along the lineal path its travel.
1.8.2 Vehicular overhead pivot gate. Shall be restrained from
movement along the translational path of its travel.
1.9 For pedestrian access in the vicinity of an automated vehicular
gate, a separate pedestrian gate shall be provided. The
pedestrian gate shall be installed in a location such that a
pedestrian shall not come in contact with a moving vehicular
access gate. A pedestrian gate shall not be incorporated into
an automated vehicular gate panel.
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 When the gate operator requires replacement, the existing gate
shall be upgraded to conform to the provisions of this
specification.
2.4 When the gate of an automated gate system requires
replacement, the new gate shall conform to the provisions of
this specification.
SAFETY
3. Vehicular Vertical Lift Gates
3.1 The following provisions shall apply to Class I, Class II and Class III
vehicular vertical lift gates:
3.1.1 All openings shall be designed, guarded or screened to prevent a 4 in.
(102 mm) diameter sphere from passing through the openings
anywhere in the gate.
3.1.2 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 4 in. (102
mm).
Exception: All other fixed stationary objects greater than 16 in. (406
mm) from the gate frame shall not be required to comply with this
section.
3.1.3 Horizontal and vertical framing members of a gate shall be smooth,
and shall not include horizontal protrusions other than gate hardware.
3.1.4 A positive stop shall be required to limit travel to the designed fully
open position.
3.2 Class IV vehicular vertical lift gates shall be designed, constructed and
installed in accordance with security related parameters specific to the
application in question.
4. Vehicular Overhead Pivot Gates
4.1 The following provisions shall apply to Class I, Class II and Class III
vehicular overhead pivot gates:
4.1.1 All weight bearing exposed rollers 8 ft (2.44 m), or less, above grade
shall be guarded or covered.
4.1.2 All openings shall be designed, guarded or screened to prevent a 4 in.
(102 mm) diameter sphere from passing through the openings
anywhere in the gate.
4.1.3 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 2 1⁄4 in.
(57 mm).
Exception: All other fixed stationary objects greater than 16 in. (406
mm) from the gate frame shall not be required to comply with this
section.
4.1.4 Horizontal and vertical framing members of a gate shall be smooth,
and shall not include protrusions other than gate hardware.
4.1.5 Where required, positive stops shall limit travel to the designed fully
open position, or the designed fully closed position, or both.
4.1.6 All jamb materials, track materials and related hardware shall be
designed to support the weight of the gate at any position of the gate.
4.2 Class IV vehicular overhead pivot gates shall be designed, constructed
and installed in accordance with security related parameters specific to
the application in question.
