Learning about rib rollers, their uses in metal roofing and which type of rib rollers are available with New Tech Machinery’s rollforming equipment can help you better understand which rib to use in your next metal roofing project.
A rib is a decorative and stiffening aspect that is formed in the flat part of a finished panel. Ribs are formed during the rollforming process through a series of rollers. However, rib rollers are not the same as the rollers that make the shape of the panel and panel legs.
Adding ribs to a panel is great for stiffening the panel and hiding defects in the material or that may occur during rollforming. If the machine is out of adjustment, it could cause oil canning and potentially deform the material. Certain ribs, like striation ribs, can help hide oil canning.
The choice to rib roll is ultimately a personal one, it can be done for pure aesthetics or for practical reasons!
New Tech Machinery offers a separate rib roller assembly. This type of rib roller is designed to sit behind the shear and consists of a frame and a set of top and bottom roller assemblies that form the ribs between the panel legs, which allows you to engage or disengage the rollers to your liking. Additionally, you can also slide the bead or rib roller assembly left or right depending on where you want to put the ribs into the panel field. On all of the rib rollers, you can adjust the depth of the rib to make them shallower or deeper as desired.
Unlike other panel profile tooling sets which are the components inside the portable rollforming machine that bend and shape the material to a specified style and create the standing panel legs used for installing the panels to the roof.
