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.
