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.
