Woven
Polyolefin Fabric.*
Primarily used in the bagging and agricultural industry
but also used in the fabric shelter industry where longevity
or value of the items being sheltered aren’t of significant
value. Offers a low cost alternative for short term applications.
Often manufactured overseas and may not be flame retardant
necessary to comply with building codes. *(Information is
provided only for your comparison. We do not carry this fabric).
18 oz. PVC
We have been fabricating with this material for over 20 years.
Some of these covers are still in place on shelters throughout
the world. We can fabricate these covers in a multitude of
patterns to create visually pleasing systems. This material
is in inventory in translucent white, opaque white, opaque
green, and opaque tan. Translucent white allows a warm glow
of natural light into your fabric building. Opaque blocks
all light from passing through the membrane (the fabric in
the upper right on this page is opaque white).
22 oz. PVC
This material is an upgrade to the 18 oz. PVC. Our 22 oz.
material is the material of choice where durability is the
main priority. This fabric is available in translucent white,
opaque white or opaque beige fabric. This fabric utilizes
a proprietary design to create some of the strongest, longest
lasting fabric in the industry. This fabric is a good choice
for your order of replacement covers for existing fabric
buildings and fabric shelters.
28 oz. PVC
28 oz. PVC is the ultimate structure material. The backbone
of this material is the polyester fiber that gives the material
700 lbs./inch tear strength. Our 28 oz. PVC is purchased
with a two part acrylic/urethane top coat. This two part
system improves weathering, abrasion resistance, and minimizes
plasticizer migration. This is the choice for consumers who
demand the highest performance characteristics from their
equipment. This is the standard material on our 150 ft. wide
span.
