Sheet Metal Strengthening Ribs

In addition bends are made at the bent corners of the bent parts.

Sheet metal strengthening ribs.

A seam is a joint where the two ends of the sheet meet. Each groove bead or line will compound the strength and can also add a design to the panel. Sheet metal with structural grooved seams. When the material is deformed to create the ribs the effective material thickness increases strengthening the material.

Pressing grooves ribs or designs into a piece of sheet metal will greatly increase the strength. Since we re talking about constant or near constant air flow through these parts the material needs to be durable enough to handle the pressure and temperature changes. Can play a strengthening role of ribs. Smacna sheet metal standards deem that ductwork of various gauges should be put through a stiffening process and with good reason.

Between two parallel ribs minimum distance is 10 times material thickness plus the radius of the ribs. The shape of the form is the result of programs created in the punch press programming system. Is there calculations which will help me determine how many ribs grooves are needed and how much doing so will strengthen the sheet metal. I have considered ribs which i probably classified wrong as grooves.

The stretched metal in those areas will hold tension in the panel and give it structural rigidity. Gussets unfortunately are not an option due to space limitations.

Hems are used to create folds in sheet metal in order to stiffen edges and create an edge safe to touch.

These can be a life saver especially if you are using the minimum material thickness to control costs. Embossing operations are commonly used in sheet metal and vary in purpose and function. The tool allows part designers to reduce sheet metal thickness without compromising the strength and rigidity of the final product.
