Custom Roll Forming | A Manufacturer's Guide to Cost Control

How Roll Forming Limits Your Total Manufacturing Cost Of Ownership

When it comes to metal forming cost, if price is the battle, total manufacturing cost of ownership – or TCO – is the war. TCO is an analysis of the complete life cycle of your purchase. The number includes every phase of ownership. Parts with a lower TCO are better in the long run when it comes to roll forming cost – even if the initial purchase price is higher. By working with a company that optimizes every step of the roll forming process, you cut costs in ways that aren’t directly related to the per-part cost. So, what are the major contributors to the indirect cost savings of a comprehensive supply planning system?

  • Equipment and material costs 
  • Personnel costs
  • Operating costs
  • Shipping/transport costs

These factors all play into long-term maintenance and investment in quality. The right manufacturer can help you lower your total manufacturing cost of ownership.

Equipment and Material Costs

These include the cost of equipment, installation, and necessary upgrades. Not surprisingly, materials make up the bulk of roll forming costs. Raw materials can be anywhere from 40% to 80% of the final cost. The cost of a material depends on its thickness, market cost, and scrap factor.  A thin, inexpensive material (like thin carbon steel) can take up 40% to 50% of the cost. If the material is heavy and expensive (i.e. copper, bronze, stainless steel), it reaches up to 80% of the total price. The great thing about roll forming is that it produces little scrap – on average, only 0.5% to 3% scrap is produced. So, there won’t be as much monetary or material waste once you buy the materials.

Personnel Costs

These include in-house staff and any outsourced help. Ongoing employee training, project management, and resources for rejects/rework also factor in. The right roll forming partner for you will employ:

  • Agile operating practices
  • Continuous process flow
  • “Pit crew” machine setup philosophy
  • Intensive employee cross-training

These practices contribute to a competitive sell price and lower your TCO.

Operating Costs

These include inventory, utility costs, waste disposal, and more. Roll forming is the most economical production process for the bending of metal channels, angles, and complex shapes – remember, there’s very little scrap compared to other manufacturing methods.  Also, roll forming produces a lot of metal roll formed profiles in a short amount of time, increasing ROI and decreasing TOC.

Shipping/Transport Costs

If your product requires secondary operations or minor assembly, some roll forming partners will add them to the end of the roll forming line. Doing this instead of adding a separate line or shipping your parts to another manufacturer saves you money.  They’ll also work with your current manufacturing shipping companies or use their own to get you the best freight rate. 

How to Reduce Raw Material Cost? Ask Your Roll Forming Company

When it comes to cost effectively managing raw materials, wouldn’t you rather work with a custom roll forming corporation that discloses the facts about the largest cost component of your parts?

To recap, the three factors that affect roll forming costs:

  • Setup time
  • Run speed
  • Materials

Of the three, roll forming raw material costs make up the biggest expense – anywhere from 40-80% of the final manufacturing cost. 

What is the Biggest Factor in Raw Material Costs? 

For a lot of industries that buy formed metal products, pricing is a bit of a mystery. These four variables are sometimes responsible for misunderstandings with buyers:

  • True rolled-up cost of raw materials (mill price + servicing cost + freight + etc.
  • How much metal is contained per linear foot of finished product?
  • How much the metal thickness varies and how that affects you?
  • How much scrap figures into the final price?

Unfortunately, failure to understand how to calculate raw material costs creates an opportunity for manufacturers to make money off you.

Instead, roll forming companies should divulge raw material prices openly and honestly. If any you work with don’t or are very hesitant to, that’s a big red flag.

The share of part cost that raw material contributes depends on:

  • The amount of metal in the part
  • The type & thickness of the raw material
  • How much scrap is produced in the process
  • Metal market conditions

Falling Prices Slow to be Passed Along

The raw material market changes all the time in metal manufacturing.

When the cost of materials is high, that gets passed on to consumers. When the cost goes down, however, a lot of suppliers are slow to pass along the savings.

Instead of staying true to the market, there may be several pennies skimmed off the top. 

Our Raw Material Philosophy

Once you have a complete understanding of a sheet steel supply chain, why should your vendor try to hide anything? Your roll forming company should be performing raw material cost analyses on a regular basis and sharing that information with you. 

Roll forming companies should practice transparency with customers by offering a structured quarterly review process as part of their standard roll forming service package. This includes:

  • Current market trends
  • Consumption rates and inventory levels
  • Bids for material to cover the next production period
  • Steel mill lead times

After many years of practicing these reviews, you and your roll forming company will know each other very well, and you’ll have a custom solution to keep your roll forming raw material costs down.

Problems With Other Systems

Other systems, like enterprise resource planning (ERP), computer systems, and barcodes, are all viable – however, we’ve found there’s too much room for human error or system failures.

With an ERP system, you might have a note that says you will use no more than three pieces of material for each unit manufactured. This sounds perfect in theory, but human error quickly gets in the way. People drop, scratch, and otherwise damage items all the time – and those instances often go unreported due to forgetfulness or fear of repercussions. So, more inventory is being used up without any documentation.

In these situations, it’s very common for the manufacturer’s personnel to go to a shelf in search of an item, only to find the inventory has been emptied. This misunderstanding of true consumption is an unnecessary waste of time and reliability for suppliers and customers alike.

It doesn’t matter if personnel use a little more (or less) than expected, with the trigger-response system. The only thing that matters for the consumption-replenishment cycle is how many unopened bundles are left on the shelf.

Raw Material Inventories

On our end, we use the same system of triggers and responses to make sure our coil inventories are correct. Wide master coils are slit into smaller run coils; when we hit the run coil trigger at our steel supplier’s warehouse, we order another master.

This system allows us to be more flexible when buying materials for clients. We don’t hoard inventory, so we can quickly change gears if a client no longer needs a certain product. We can stay close to market pricing as well, rather than gambling with your raw material dollars.

2. Quarterly Reviews

To make sure you’re getting the most out of our supply planning system, we sit down with you and discuss the results. Quarterly reviews are frequent enough to catch issues as they crop up, and make small changes for the next review.

In particular, we like to make sure the inventory levels are spot on. We track all feedback from clients and after one year, we can optimize for your activity levels in each quarter.

Also, we like to collaborate with our clients to plan the next materials purchase. We discuss:

  • How much we have in our inventory
  • How much you need
  • What the market looks like for your material
  • Changes in estimated annual volume
  • Pending design changes for your roll-formed parts
  • Freight utilization
  • Cost-saving ideas

Because we work directly with you, you’ll get exactly what you need for your specific roll forming process.

3. Quality Systems

Dahlstrom Roll Form isISO : certified, uninterrupted since . This certification indicates that our quality management system meets the International Organization for Standards’ global requirements. 

Proofs of the quality system include:

  • On-time delivery percentage (99.5% in )
  • Field defect parts per million (3,827 in – four sigma level is 6,210)

Our customers enjoy the confidence that comes from quick delivery times and a low PPM defect rate.

4. Safety

Aside from being ISO certified for quality management, we’re also SHARP (Safety and Health Acknowledgement and Recognition Program) certified for our safety practices. This certification is the highest recognition given by OSHA for exemplary safety practices.

By promoting safety for our employees, we also promote safety for our customers. Some of our safety precautions include:

  • Weekly housekeeping & organization audits: Removing clutter and potential hazards from the workspace
  • Monthly safety training: Bringing in a safety consultant to talk to the whole staff about general safety practices (lifting heavy things, hazardous chemicals, personal protective equipment, etc.)

We are audited by the Department of Labor regularly to maintain our SHARP certification.

5. Cross-Trained Workforce

Our personnel has a vested interest in the success of your product. All of our operators are paid by the acquisition of skill rather than tenure. The faster they learn and the better their skills, the more they get paid. They have every reason to put out the best quality parts for you.

This program includes cross-training for different roll forming machines and client jobs. If something were to happen to the primary employee who runs your product, there’s guaranteed to be another person who understands your tooling costs and part quality requirements.

That means your project will be on time, and you’ll have no unexpected delays on the roll form line or increased costs for idle time.
