Finishes
1.
Green Coated. (Suffix
GR)
Green urethane powder resins
are
applied electrostatically
to the
steel
after
fabrication. Once
the
material
is
completely covered with
the
pow-
dered-form urethane,
it
proceeds
through
a
400°
baking process
for ten
minutes,
creating
a
chemical bond.
This
results
in a
minimum
of
1.5
mil
thickness
of
urethane
coating
provid-
ing
excellent resistance
to
chipping
or
peeling.
2.
Pregalvanized Steel. (Suffix
PG)
In
addition
to the
standard
Galv-Krom®
finish,
all
Kindorfchannels
are
avail-
able
in
pregalvanized steel. This mate-
rial
is
identical
to the
standard steel
except
for its
ASTM
G-90
zinc coating.
This
coating
is
applied
at the
steel mill
prior
to the
channel fabrication.
3.
Electrogalvanized
(Suffix
EG)
Often
referred
to as
"zinc plated"
or
"electroplated
zinc,"
the
steel
and .5
mils
of
zinc
are
bonded
by an
electrol-
ysis
process. This
is the
identical
process used
in the
Kindorf Galv-Krom
finish
without
the
numerous benefits
of
the
gold
colored dichromate conver-
sion
coat
(see Galv-Krom
finish
for
more information). Electrogalvanizing
is
most
commonly
applied
to
small fit-
tings,
hardware
and
threaded products.
4.
Hot-Dipped Galvanized (Suffix
HD)
The
material
is
zinc coated
after
fabri-
cation
providing
total product protec-
tion
on all
surfaces.
The
fabricated
channel
or
fitting
is
suspended
and
then
dipped
into tanks
of hot
zinc
for a
prolonged period, creating
a
coherent
bond.
The
result
is
superior corrosion
resistance
as
compared
to
pregalva-
nized material.
Hot-dipped
galvanizing
is
not
recommended
for
threaded
products, considering
the
zinc coating
thickness
will
often disrupt
the
threads.
Kindorf
hot-dipped
galvanized
is in
conformance with ASTM Specifications
A-123
(formerly A-386)
and
A-153.
Kindorf
channels maintain
a
mini-
mum
1.5
ounces
of
zinc
per
square
foot
of
steel
or 2.5
mils (ASTM
A-123,
Thickness Grade 65).
This
finish
is
also referred
to as
"Hot-dipped galva-
nized after fabrication."
5. PVC
Coated (Prefix
P)
A
polyvinyl chloride (PVC) plastic coat-
ing is
fused
to the
channel, fitting
or
accessory after fabrication
by
immers-
ing the
part
in
fluidized
PVC
tanks.
The
fused-melt
mixed
powder
PVC
coating
thickness
is 15
mils (.015") plus
or
minus five mils.
PVC
material
is a
ther-
moplastic
and
will soften
in
high tem-
peratures.
An
inherent weakness with
PVC
coatings occurs when field alter-
ations
are
applied,
such
as
cutting
or
drilling.
These acts disrupt
the
sealed
PVC
product
and
warrant field touch-
up.
Kindorf cannot
be
held responsible
for
field-altered
PVC
coated products.
Materials
1.
Standard Steel.
The
standard
Kindorf
8
Channel
is
made from high quality carbon steel
sheet. These
sections
are
cold
formed
into
a
unique
and
modular profile
by
an
efficient
roll forming process.
Additionally,
the
process"cold
works"
the
steel
is to
give
it
greater mechani-
cal
properties.
2.
Extruded Aluminum. (Suffix
AL)
For
more corrosive environments,
Kindorf®
also
offers
extruded aluminum
channel sections. These section
are
nearly
identical
to
their steel counter-
ports.
Aluminum channel
is
made from
6063 Aluminum
and
heat treated
to a
T-6
specification.
3.
Nonmetallic. (Suffix
N)
Kindorf®channels
are
also available
in
fiberglass
reinforce polyester
and
vinyl
ester.
These products
are
pultruded
into shapes similar
to
steel channels.
They
offer
a
high degree
of
corrosion
protection
and are
very lightweight.
4.
Stainless Steel. (Suffix
SS)
For
the
most corrosive environments,
Kindorf®
offers
Type
304
Stainless
Steel
channel sections
and
acces-
sories.
Type
316
stainless available
upon request. Contact your
local
sales
rep.
These products
are
identical
to
their
carbon
steel
counterparts
except
for
a
much greater corrosion resis-
tance.
