PRODUCT DESCRIPTION
Basic Use: Areawalls allow air, light, egress
and/or access into a basement or below ground
level structure by acting as a structural barrier
to hold back the surrounding backfill. They are
adaptable and can be used as protective barriers,
conveyor covers, air-conditioner retainers and
small retaining walls.
TECHNICAL DATA
Areawalls: Corrugated, galvanized steel used
has a 2.66” crest to crest measure by ½” depth
annular configurations commonly referred to as
2 ½” x ½” corrugation. Steel thickness is
determined by grade ordered and ranges from 18
gauge (.048 dec.) through 16 gauge (.060 dec.)
Zinc coating (galvanized) is (G-90) ASTM A 653
M quality or better. The exposed top edge has a
5/8” minimum roll-formed bead on all heights of
areawalls. The 48” high and higher areawalls
have SPC’s exclusive roll-formed double bead on
both top and bottom edges for additional strength
and safety in handling. All styles include a wide
flange for wall attachment which is pre-punched
with ½” holes. Areawalls are one piece units
up through 60” in height. 72” high areawalls are
spot-welded together to insure integrity. Standard
heights available: 12”, 18”, 24”, 30”, 36”, 48”,
60”and 72”. The order height is full nominal
height, i.e., 24” measures 24”. The areawall model
number such as ES4618-36” designates the grade
(E) Economy grade, (S) Straight Style, (46”) inside
width, (18”) projection from the wall and
(36”) height.
WARRANTY
St. Paul Corrugating Co. warranties areawall
products for a period of thirty years to be free
from defects in manufacture and to be in
conformance with our quality control
requirements; and limits its responsibility to
replacement cost of material only. Installation of
any non-ventilated cover product preventing air
circulation over galvanized metal will void all
warranties.

STYLES
Streamline Straight: Radius corners
and straight face reduces projection but
allows maximum opening for light and air.
Round: Utilizes arch principle for
maximum strength where projection
away from wall is not critical.
Casement Square: Projection from wall
to width of opening exceeds all other
styles. Applications are large casement
accessways, air-conditioner retainers and
code required basement egress exits.

INSTALLATION
The areawall should be extended beyond the
rough opening of the window by at least 3”.
Some building codes may require additional
clearance. The top of the areawall should extend
approximately 2” above the established grade line
and down at least 12” below the windowsill. If in
doubt, go with a higher wall since extensions are
difficult to attach. Fill the space below the
window well with select gravel for drainage.
Flanges should be attached to the foundation wall
at sufficient points (12” centers minimum) to
assure structural stability. Use Sleeve or wedge
type anchors appropriate for your foundation
construction. Anchors are not provided. Select
backfill material should be used, such as granular
with some clay that is free of large rock and earth
clods and should not be frozen material, sod,
cinders or other active soils. The load carrying
capacity of the areawalls is largely dependent
upon proper backfill procedure. The fill should
be placed evenly around the areawall in 12”
layers using ordinary compaction making sure the
shape is not distorted. On larger sizes a 90 %
density factor may be desirable. Compacted fill
around the outside of the areawall should be at
least 12”, or one-half of areawall projection. We
recommend supporting the areawall inside face
during the back-filling procedure.
MAINTENANCE
Areawalls are galvanized and therefore
maintenance free for a period of years. Painted
grates require periodic touch ups.
BAR GRATES
Cover the areawall opening to help avoid
accidents while permitting air and light into the
opening. Grates are fabricated from 3/16” hot-
rolled flats, ¾” and 1” wide welded on 2” center
spacing with angle clips on frame. The grate is
made to fit down inside the areawall with the
angle support clips resting on the top bead of the
areawall. Bar Grates are painted gray.
