• Evaluate options before investing.
Ideally, you want to invest in the most efficient formwork for your individual project. There are likely many new and used options on the market that will work, but you should be discerning about which formwork you choose. Keep in mind that the formwork with the cheapest upfront cost isn’t necessarily the most cost-conscious option in the long run, especially if it increases labor costs due to factors like being time-consuming to install or strip.
• Consider buying used.
The Eiffel Trading marketplace is a hotspot for both buying and selling used concrete formwork. Our inventory is ever-growing, and includes various formwork options including overhang brackets, stripping buggies, various types of concrete formwork systems, and more. Purchasing used (instead of new) can save you tens of thousands of dollars on a system that will still last for years to come. This is a great option for any contractor looking to save money on concrete project costs!
• Get a professional opinion.
Make sure someone who’s highly experienced with formwork evaluates possible formwork options before you make any investments.
• Keep it simple.
The easier it is to erect and remove, the better. Additionally, it should be easy to use once erected. You want to be able to pour the concrete efficiently and depend on the formwork to do its job. Formwork that decreases labor time decreases costs and vice versa.
• Consider ergonomics.
Formwork that’s lightweight and easy to work with is ideal. Heavy, unwieldy formwork can cause difficulties and ultimately be more time-consuming to use. Additionally, it may lead to more safety risks and issues.
• Minimize assembly costs.
It helps if formwork is standardized and uses sizes that are standard to the industry. Custom formwork and formwork that requires modification onsite can increase both the cost of labor and the cost of materials. At times custom formwork must be used, but it’s best to avoid it if the project does not specifically require it.
• Opt for reusable options.
Engineered (steel and aluminum) forms are a great choice because they can be used and re-used over and over again for different areas of projects without having to be replaced. Additionally, engineered forms can be sold to another if no longer needed after projects are complete, and they hold onto their value quite well.
• Consider other, project-specific factors.
Your cost-conscious formwork plan should include factors like crane availability, ease of access to the job site, and the number of employees assigned to the job as well as the level of employee experience. Additionally, you should have a clear-cut schedule in place for formwork-related components of your project and do your best to incorporate ways to avoid delays into your overall plan.
Final Thoughts
Decrease your overall project costs by picking the best formwork for the job. Oftentimes, paying a little more upfront is the better financial decision, especially if you can sell the formwork or continue to use it for future projects. You ultimately should strive to invest in formwork that boosts both productivity and safety. If in doubt, consult with an experienced professional who can help you find the best forms for your project.

While roll form tooling might seem like an unsightly up-front expense, you can actually realize cost savings with roll form manufacturers. The instances are both large and small, including:
- Free stuff
- Lower part cost
- Lower labor cost
- Less lead time
- Optimized parts
Tooling costs in manufacturing are already a sore spot for many purchasers, but some think roll form tooling is cost-prohibitive altogether. The up-front price tag tends to blind them to literal down-the-line savings.
That’s right -- if your project fits, a roll form manufacturer can actually optimize your spending and get your parts out the door sooner and for less money per part.
To get a true understanding of roll form tooling costs, let’s start with the bad and then reveal the good of roll form tool design.
Why Roll Forming Tooling Is (Reasonably) Expensive
Tooling is reasonably expensive, depending on the shape’s complexity. Roll form tool design fundamentals will tell you easy shapes are cheaper, while more complex shapes are more expensive. Roll form tooling material type and thickness also matter. When more work needs to happen to form the metal, more forming stations (and tools) are necessary.
Part “depth of profile,” or profile height, may add to the cost of roll forming tooling design. Taller profiles need roll form tools with larger diameters, which adds to the amount of tool steel needed.
When you add prepunching to the shape, it becomes even more expensive because now you have to pay for the prepunch die. Also, the number of different punch shapes in the profile is directly proportional to the cost of the prepunch tool.
It is ideal for part run speed to pack these punches as densely as possible into the footprint of the pre-punch die because fewer stops to punch the part during forming equals lower part cost.
As a more specific example, let’s say a part is 10 feet long and needs a hole every 6 inches. Your roll form vendor should be making a tool that will make a punching stroke on the metal strip the fewest number of times possible.
The ideal setup for part cost in this example would be a 10 foot long punch press that has adequate tonnage to pre-punch the coil strip one time and a 10 foot long die with all of the holes needed. This would be the most expensive pre-punch die you could buy for this part, but the part cost would be the lowest possible due to a very high run speed. More typical would be a press with a 3-4 foot bed -- fewer holes per press hit but more coil strip stops.
Your vendor should be creating a tool that makes the optimal number of punches per hit and hits per part based on the equipment available and the volume of parts to be produced. Higher volumes will, of course, justify higher punch die cost because the return on investment is faster.
WHY ROLL FORM TOOLING COSTS ARE ACTUALLY LESS THAN YOU THINK
While tooling might seem like an unsightly up-front expense, you can actually realize cost savings with roll form manufacturers. The instances are both large and small, including:

1. Free Stuff
In cases like the example above, after you buy punch tooling, you effectively get the holes put in the part for free since the shape has to be formed anyway and the punching process is connected and continuous. When you specify certain bends, grooves, hems, or folds in your design, adding one more bend is free after the tooling is purchased.
Unlike traditional metal fabrication where adding any feature is a recurring and cumulative cost, roll forming metal is based on machine run time -- no matter how many features are added. A custom roll formed product is almost always a wise spending choice.
2. Lower Part Cost
There’s a proportional relationship here – the amount of tooling cost you add is repaid to you in the features that are brought to you more efficiently.
Compare that payback to a multistep job shop process:
- Cutting the piece
- Taking it to a press or laser cutter
- Taking it to a brake press, where someone sets tooling and bends it to profile
With a roll former, those are all handled in a continuous process. Job shops are more suited for custom projects with constantly changing products -- so why use custom-enabled capacity to make a common, high-volume component? Roll forming is ideal for repeatable products and processes.
3. Lower Labor Costs
With fewer processes involved, it’s only logical that you also benefit from tremendously lower labor costs by enlisting roll formers. We’re talking 6% of the total part cost, compared to 15-20% at a job shop.
4. Less Lead Time
Lead time on a per-part basis is way better with roll form tooling –as in, 10% of that job shop’s lead time. Roll form manufacturers are continually striving to streamline their processes and manufacturing floor layouts to benefit customers.
5. Optimized Parts Thanks to Experienced Roll Formers
If your manufacturer participates in part design, it may actually save you money on tooling by optimizing the part for roll form processes.
TAKE THE PAIN AWAY WITH A ROLL FORMING SUPPLIER AGREEMENT
In addition to these general benefits of roll form tooling, there are specific ways Dahlstrom makes budgeting easier on you.
1. Thousands of Existing Tools
With over 115 years of experience, we’ve racked up an archive of over 1,400 existing tool sets. We may already have tooling that will work for you, so you may be able to skip additional tooling costs altogether.
2. Joint Investing
In the case of very expensive and multiyear programs, we may be interested in investing jointly in tooling with a customer.
Take an example of 50,000 feet of product in one year. If the parts are 10 feet long each, that's only 5,000 pieces -- well within a job shop’s wheelhouse and not super appealing for a contribution from us toward tooling cost. But, if it’s going to continue for 5-10 years, we’re talking 250,000 to 500,000 feet. In a joint investment situation, we might pay 50% of the tooling in exchange for your long-term business. Larger programs may qualify for free tooling.
3. Amortized Tooling Cost
You give us a down payment, and we can amortize the tooling cost over the part cost. This means you pay a little bit of the tooling cost for every part you buy.
For instance, if you order 100,000 feet per year and your tooling is $100,000, you might pay $1.00 per foot over one year instead.
OTHER OPPORTUNITIES WITH ROLL FORMING
Once you get past roll form tooling manufacturers' reputation for being expensive, you’ll score additional chances for:
- Higher-volume orders (better cost efficiency)
- Larger runs (see above)
- Expanded in-line fabrication (lowering labor costs)
- Saving your custom forming and fabricating capacity for your customers
