3. 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 suitable
as air conditioner retainers or egress exits. They are adaptable
for use as tree-wells, protective barriers for meters or
other utility installations, fenders for trucks, lawn edging,
conveyor covers and small retaining walls. Bar Grates cover
the areawall opening to help avoid accidents and are classified
as “light-duty” grates.
Composition and Materials: Areawalls
are fabricated from pre-galvanized, corrugated steel in
various gauge thickness depending on the grade selected.
The steel sheets have a commercial (G-90) ASTM A 653 galvanized
coating to better assure longevity. Bar Grates are fabricated
from hot-rolled steel strips, formed, welded and painted
after fabrication. Hot dipped galvanized grates are available
on special order.
Grades: Areawalls are manufactured
in three grades: Imperial, Economy and Thrift-T.
Imperial Lux-Right™: Most
complete range of sizes and styles available. Manufactured
from 16 gauge, pre-galvanized steel sheets.
Economy Lux-Right™: Duplicates
the styles and size range of the original Imperial grade.
Manufactured from 18 gauge, pre-galvanized, regular spangle
steel sheets. Considered the standard in the industry, this
popular alternative is economically value priced under our
Imperial grade and is adequate for most applications unless
the deeper and larger size areawalls are required.
Thrif-T Lux-Right™: Manufactured
from 20 gauge range of pre-galvanized, lock-forming regular
spangle steel, 37” wide in two styles (Straight and
Round). Accepted as the standard size and grade typically
available at the local level through building supply outlets.
Limitations: Care should be
used in selecting the style and grade of larger and deeper
areawalls. They should be specified in heavier gauge and
properly supported during backfill and while other construction
activity is taking place.

STYLES:
| Straight
Radius corners and straight face reduces projection
but allows maximum opening for light and air. Harmonizes
well with current building lines. |
Round:
Utilizes arch principle for maximum strength where projection
away from wall is not critical. |
Square
Projection from wall to width of opening exceeds our
other styles. Excellent for large casement access ways,
air-conditioner retainers and egress exits. |
Foundation Vent Areawalls:
Illustrated below.
Inside Corner Areawalls:
Designed for windows located near wall projections
such as inside corners, fireplaces and chimneys. See selector
chart.
Sizes: See selector chart.
Special sizes available in all grades and styles; contact

4. 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 20 gauge (.036 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 ease in handling
(Thrif-T grade included). All styles include a wide flange
for wall attachment which is prepunched with ½”
holes. Most areawalls are one piece units up through 60”
in height and incorporate the flange as an integral part
of the areawall. Higher and wider areawalls are spot-welded
together to insure integrity. Standard heights available:
12”, 18”, 24”, 30”, 36”, 48”,
60”and 72”. Higher areawalls are available,
inquire. The order height is full nominal height, i.e.,
24” measures 24”. The areawall article 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.
Bar Grates: 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. Stock grates are painted gray. Galvanized
grates are available on special order.

5. INSTALLATION
The areawall should be extended beyond the rough opening
for the window by at least 3”. Some building codes
may require additional clearance. The top of the areawalls
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 masonry nails, self-drilling anchors or other approved
fasteners. 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 backfilling procedure. Care should be used
in selecting the grade and style.
