The Case for Roll Forming Services: Cost, Capabilities, Quality

You’ve got a project. You’ve also got options for how you complete it, one of those being roll forming services.

Indeed, roll forming is far from the only game in town.

Today, there are four main metal forming services used in the manufacturing industry:

• Roll forming
• Braking
• Stamping
• Extrusion

Guess which metal-forming method is best for you? (Hint: It’s in our name.)

Why should you feel this way, too? Let us count the ways.

… But What are Roll Forming Services?

First off, for the uninitiated: Roll forming is a metalworking process that uses contoured tools to bend flat material into a finished, uniform profile.

Engineers and architects request roll forming when they require a bend -- sometimes multiple bends -- of a metal channel, angle, or complex shape.

Manufacturers can roll form before, during, or after other fabricating steps. The process is repeatable over long runs.

Roll Forming Cost

Tooling for roll forming can get expensive, but long-term use will eventually net you cheaper labor costs per piece. Besides, if you buy intelligently, the “roll forming tools are too expensive” argument evaporates into myth.

If you can weather the tooling costs, you’ll open opportunities for:

• Higher-volume orders (better cost efficiency)
• Larger runs (see above!)
• Expanded in-line fabrication (lowering labor costs)

A roll forming line feeds material via coil, reducing material handling and equipment run time costs. There’s less wear and tear on the tools. Scrap waste simply ceases to exist. What more could you want?

Meanwhile, certain other processes (ahem, press braking) require separate, secondary processes for:

• Punching
• Perforating
• Notching

Naturally, this adds labor and other costs.

Roll Forming Capabilities

This flexible process allows you to add tooling to create any shape, no matter how complex the profile. (The ideal use is for long, slender shapes.)

Because the material is coiled and fed through, there are no limits on length. Custom roll forming also allows the shaping of metals already:

• Painted
• Plated
• Coated

Material-based limits to roll forming are also nearly nonexistent. (Take that, extrusion!)

The process works with:

• Aluminum
• Carbon steel
• Copper
• Bronze
• Brass
• Perforated metal
• Prepainted coil steel
• Even some non-metal materials!

That wide variety of material can turn into specially shaped parts: Get ready for:

• Graceful curves
• Awesome arcing
• Even spirals of a helix!

OK, just one more list of capabilities. Roll forming also allows for the in-line addition of:

• Holes
• Notches
• Embossments
• Slots
  
  

Roll Forming Quality

Perhaps the more striking quality about roll form services is it produces parts that are more consistently uniform across runs.

It might surprise you to see how precise roll forming can be. The machines can easily form high-strength steels while accommodating for springback. Even extremely tight tolerances are no match for roll forming.

We haven’t forgotten about those of you more worried about looks -- roll forming creates an attractive finish. It’s great for aesthetic projects where tool marks from other types of forming are not an option.

Roll with the Right Manufacturer

If you need a way to carry out your project -- especially if it’s a medium-to-high-volume one -- roll forming is almost always the answer.

What’s even better than the roll forming process? A great roll forming vendor. Just one example of many: If your manufacturer also aids in part design, it may be able to cut tooling costs by optimizing the part for roll forming.

So now that you know what roll forming brings to the table, it’s time to start considering what a comprehensive partnership can do for you.
