Product Overview

MATERIALS
Carbon Steel
Channels made from high-quality carbon
steel are continuously roll formed to
precise dimensions. By cold working the
steel mechanical properties are increased,
allowing lightweight structures to carry the
required load. Corrosion resistance of
carbon steel varies widely with coating
and alloy. See “Finishes” for more detailed
information.
Stainless Steel
Stainless steel channel is available in AISI
Type 304 or 316 material. Both are
non-magnetic and belong to the austenitic
stainless steels group, based on alloy
content and crystallographic structure.
Like carbon steel, stainless steel exhibits
increased strength when cold worked by
roll-forming.
Several conditions make the use of
stainless steel ideal. These include
reducing long term maintenance costs,
high ambient temperatures, appearance,
and stable structural properties such as
yield strength, and high creep strength.
Type 304 resists most organic chemicals,
dyestuffs and a wide variety of inorganic
chemicals at elevated or cryogenic
temperatures. Type 316 contains slightly
more nickel and adds molybdenum to give
it better corrosion resistance in chloride
and sulfuric acid environments. More
specific information concerning the
differences between types 304 and 316 is
available from Cooper B-Line.
Aluminum
Cooper B-Line’s standard aluminum
channel is extruded from aluminum alloy
6063-T6. Strut fittings are made from
aluminum alloy 5052-H32.
The high strength to weight ratio of
channel made of aluminum greatly
reduces the overall cost of installation
through ease of handling and field cutting.
Aluminum owes its excellent corrosion
resistance to its ability to form an
aluminum oxide film that immediately
reforms when scratched or cut. In most
outdoor applications, aluminum has
excellent resistance to “weathering”. The
resistance to chemicals, indoor or
outdoor, can best be determined by tests
conducted by the user with exposure to
the specific conditions for which it is
intended. The corrosion resistance of
aluminum to some commonly known
chemicals is shown in the Corrosion
Chart. For further information, contact
Cooper B-Line Systems, Inc. or the
Aluminum Association.
Fiberglass
Cooper B-Line offers two fire retardant
(FR) resins for strut systems, polyester
and vinyl ester. Both resins are ideal for
corrosive environments or nonconductive
applications with moderate strength
requirements. Some common types of
environments where Vinyl Ester Resins
are recommended, that Poly Esters are
not, are paper mills, most any metal
plating operation and any condition with
concentrated levels of Chlorine, [ Cl
-
].
Please consult our fiberglass corrosion
resistance charts on pg. 173 for specific
chemical recommendation data.
Unlike other base materials depicted in
this catalog, fiberglass exhibits unique
physical property changes when operating
in elevated temperature conditions, that
are a fraction of increase compared to
steel or aluminum. This being true,
Cooper B-Line advises against using
fiberglass in temperatures greater than
200° F.
Please refer to the "Corrosion Resistance
Guide" below for specific applications.
Cooper B-Line Fiberglass Strut systems
are manufactured from glass fiber-
reinforced plastic shapes that meet ASTM
E-84, Class 1 Flame Rating and self-
extinguishing requirements of ASTM
D-635. A surface veil is applied during
pultrusion to insure a resin-rich surface
and ultraviolet resistance.
While polyester is sufficient for most uses,
vinyl ester is suitable for a broader range
of environments.
