Roll Formed T & H Sections:
are unique profiles in that they
are usually made of thinner materials
than Bar Stock, and are unable
to be produced by any other method.
This is because they are made
from continuous metal coil stock
that requires some area such as
the stem of the T, or the center
and at least one side of the H,
to have a double thickness in
order to form it by Roll Forming.
H sections may also have a half
of each side as double thickness
areas with the center a single
thickness. This method requires
the least amount of metal and
tooling cost to produce an H Section.
For T sections, in some cases,
the stem of the T may be a single
thickness and half of the top
of the T may have a double thickness.
To understand this concept more
easily, for example, you can imagine
that you have a 12” long
strip of paper that you fold together
to be a T or H shape that is 12”
long. This is how Roll Forming
produces these shapes. Profiles
are gradually bent, (folded),
in a series of stations, a little
at a time, from continuous metal
coil stock. Each station has a
powered top and bottom roller
that the metal moves through,
bending more in each station,
until it exits as a finished T
or H shape. There is more roll
die tooling and thus expense to
form an H shape than a T shape
as the H section has more bends.
A T section that has a double
thickness area on it's stem, requires
more metal to be used, than a
T section with a double thickness
on half of the top. This increases
part cost and die cost, however,
the double thickness stem, that
increases the metal required,
makes a stronger part. T Sections
can have a specifically desired
opening in the stem, as opposed
to a double thickness stem that
is closed. Some designs will have
more double thickness areas than
necessary, purposely, to increase
the strength of the part more.
Some designs will have the outside
edges of the metal hemmed, before
being formed into the shape, for
extra strength and deburring qualities.
When this is done, there is an
increase in metal and forming
stations required, increasing
part and die cost. T & H Bars
that we produce by roll forming
are not made to equal the strength
of heavy duty single thickness
extruded or hot mill rolled bars.
Our bars are lighter duty and
are made from .005” through
.125” thicknesses, and more
economical with better tolerances
than brake press forming. Our
T and H sections can also be smaller
or more unusually dimensioned
than any standard bars available,
by other production methods. Prefinished
metals and Inline Notching makes
Roll Formed Sections like these
much more desirable when strength
does not have to match bar stock.
Print examples show styles of
T and H sections and tooling that
is available.
W Bars & Double Channels:
are very similar to each other.
The difference is that Double
Channels have a double thickness
area in the center. This makes
W Sections less expensive on
part and die cost than Double
Channels. It is also possible
to make triple channels or as
many channels, in the width
of the section, as it is possible
in our 28 station roll forming
machine. Shapes like this are
more often corrugated with multiple
W Sections in the width similar
to corrugated roofing panels.
Double Channels are commonly
used as tracks, frames and holders
while W Sections though used
as tracks, are also used in
many other industries for all
kinds of uses such as Framing,
Reinforcements, Stiffeners,
Rails, Brackets, Plates, Battens,
Baffles, and Slats, among others.
Prefinished metal and Inline
notching make this process even
more economical and has closer
tolerances than press brake
operations. Print examples show
tooling available and types
of W Sections and Double Channels.
