Roll Forming Line
Dassnagar designs and manufactures high
speed Roll Forming Lines with entry cut-to-length section, catering to ferrous and non-ferrous metals. Since
shipping our first Roll Forming Line in 1986, we have developed tooling for over 100 custom
shapes
ranging in complexity from simple sinusoidal/trapezoidal roofing sections, angles and channels, to more exotic shapes, requiring multi-stage
operations. Special purpose roll forming lines for products requiring
strength and rigidity (e.g. Guard rails
of Metal Crash barriers) are also available.
From input coils to finished roll formed products, excellent coil processing solutions are
available with in-line operations like un-coiling, strip levelling, punching,
embossing, shearing, forming, stacking and packaging. Our shape
correction Levellers are suited to shape correction of roll formed products.

Roll Forming Technology
Roll forming is a is a high-speed production
process that can produce uniformed cross sectional dimensions throughout the length
of the part.
It employs a series of paired roller dies to
progressively shape a flat strip of metal into a desired contour such as a
channel, an angle, or a tube in the process adding rigidity and strength to the metal.
Practically, all metals can be successfully roll formed.

Custom Roll Forming benefits
- High-speed, high-volume fabricating process,
- Infinite number of shapes possible,
- Thinner cross sections and practically any length can be roll
formed,
- uniformed cross sectional dimensions throughout the length of
the part,
- Almost any metal can be roll formed,
- Eliminates multiple operations - secondary operations can be done at the same time, e.g.,
punching, notching, etc., thus saving valuable time

Salient Features
Dassnagar continuous Roll Forming lines come with
a shearing section, employing mechanical start-stop or
flying die shears.
Flying die shearing lines are more expensive and used to
process soft material and colour coated strips, requiring high surface
finish. In all other cases roll feed lines are used. Flying shears are
generally employed in post-cut roll forming lines.
