NOTE: In salt-laden or corrosive industrial
atmosphere, either Class 2 fabric with 610 grams
(2.0 ounces) of zinc coating per square meter (foot)
or Type I, aluminum-coated fabric, will be
specified. In other areas, Class 1 with 370 grams
(1.2 ounces) of zinc coating per square meter (foot)
or Type I will be specified. Class 2b polyvinyl
chloride-coated steel fabric may be specified for
other than security purposes when esthetics is of
prime importance and the additional cost is
justified. Fabric height will be shown on the
contract drawings. Fabric height shall be 1.83 m (6
feet) for controlled areas and 2.13 m (7 feet) for

GATES
**************************************************************************
NOTE: Type of gates will be shown on the drawings,
including degree of swing required. In heavy use
conditions overhead slide gates should be considered
if clearances permit, because these gates require
less maintenance and repair than cantilever gates.
Ground level track and roller systems should be
avoided in climates where snow and ice may
accumulate. Recessed tracks should never be used in
climates where the recess may fill with ice and
snow. Where gates are to receive electric locks,
the gate post foundations should be lowered to frost
depth to help prevent misalignment of the lock
components.

Gate frames shall conform to strength and coating requirements of ASTM F
1083 for Group IA, steel pipe, with external coating Type A, nominal pipe
size (NPS) 1-1/2. Gate frames shall conform to strength and coating
