Solar C-Profile Production Line

Yes; with a cassette change, C, U and sigma sections run on the same frame. If you switch often, we recommend a quick-change cassette configuration.

A hydraulic press unit is integrated into the line; mounting holes and adjustment slots are punched before the profile is cut — no second operation needed.

With roller surface and pressure matched to the coating, it stays intact. Our rollers are made from 4140 steel and hardened to 58-60 Rockwell.

Because it decides both the corrosion life and how the section can be formed. Hot-dip galvanized coil and zinc-aluminium-magnesium coatings such as Magnelis behave differently at a tight radius, and the coating also determines what happens at the cut ends and the punched holes, where bare steel is exposed. Zinc-aluminium-magnesium coatings are chosen partly because they give some self-healing at cut edges, which matters on a profile that is punched and sheared thousands of times. Tell us the coating with the drawing — the roller radii are set for it.

It is possible but it is the wrong way round for this product. Punching a formed section means punching through a curved or stiffened area, which distorts the profile locally and leaves a hole that is harder to control dimensionally. Punching flat keeps the pattern accurate and lets the whole thing be done in one pass through the line. The reason solar profiles are punched in line at all is to remove site drilling — doing it afterwards puts that cost straight back.

If it is a change in hole positions or lengths, it is a recipe change and no tooling is involved — that is what the punching stations and the length recipes are for, and it is why solar work suits this kind of line. If the profile section itself changes, that is a roller set question and a different conversation. Worth separating the two when you are planning: layout changes are routine, section changes are not.

Not if the radii and pressures are right for it. Zinc coating is more brittle than the steel underneath, so damage shows up as fine cracking on the outside of the tightest bends rather than as visible peeling. That is a tooling design question, decided when the roller set is made rather than adjusted afterwards. It is also why sending the coating specification with the profile drawing is not a formality.

Hat, C and Omega sections cover most of it, in various depths depending on span and wind zone. The structural design is the plant designer's responsibility and it varies a great deal by country — snow and wind loading move the section size more than anything else. We tool to the section on your drawing; if the project is at an earlier stage than that, it is usually more productive to fix the structural design first and specify the line around it than the other way round.
