Steel Siding Engraving Machine

Could you use a knurled roll to put a pattern on the steel through pressure as it comes off the roll ?

I never heard about that kind of rool, where could i find one Thanks Grant

Hi Pierre, How wide is the finished siding? Why not just add a V shaped form in the dies that adds a (triangular) shape down the center of the siding to prevent if from buckling and waving. Depending on the width of your siding, more than one could be used. Alternately, you could put a number of (right) angle bends down the length that resulted in a channel being formed in it. Either method would add stiffness and prevent waves in the siding.

Add dimples, i.e. golf ball dents, you will achieve a certian strength and remove most but not all of the wave, And the V the others are suggesting, well they already make that, dont they?

The Dimples will do little or nothing to stiffen the siding and preventing waving in it.
Visually they will make them less noticeable though.
As to the fact that they already make siding with ridges in them: you are right. It works, that is why they do it.

Please send data and or drawings of you panels and we will submit a design and quote to stamp the prototypes and or low volume production. Take a look at our equipment on our website. You will see that we are well equipped to handle this kind of project with very quick lead time. We will do this with very cheap tooling to prove out the design. If you have a design in mind, perhaps your company logo, for the embossment area, submit it also and we will see how we can incoporate it in to a design to keep the panel straight. cypressmanufacturing.com stackpoole77@yahoo.com

When it comes to steel construction, almost everything has been tried in the past, so you should use as examples methods which have worked for others.

Barring this; you could try the method for stiffening metal called Diamond Plate; where a diamond shape is stamped into the metal.

You will need to make the pattern "Tile-able" so that the edges of the sheets can be overlapped like shingles on a roof to prevent water leaks. The diamond shape should work well for roofing where run-off must be channeled to prevent the water from running uphill as it rolls off the edge by pressure differential (vacuum).

Hi again Pierre.
The kink or triangular shaped ridge(s) that I suggested running down the length of the siding to prevent warping will do the job. They also have the advantage that you may be able to get your existing forming rollers/dies modified to accommodate them without having the expense of having to make brand new forming dies/rollers.
I would suggest that if you want to try some sorts of ridges running parallel to the edges of the siding, that you cut a number of lengths of your raw material and take them to a sheet metal shops along with profiles of the shapes you want to try. They can then make you lengths of the different profiles relatively cheaply before you lay out significant money to get new forming dies made that you may not like the look of or that don't do the job.
