What Information Do You Need for a Roll Forming Quote?
Resources
An accurate roll forming quote starts with a clear picture of the part and its production requirements. The manufacturer needs enough information to understand the component, estimate its production needs, and identify factors that may affect cost and timing.
What Should You Include in a Roll Forming Quote Request?
At a minimum, provide:
- A technical drawing or, for a catalog part, the part number and applicable dimensions
- The total quantity or required linear footage
- The finished part length or lengths
- The material type, grade, and thickness, if known
- The required tolerances, with critical tolerances clearly identified
- The required delivery date or project deadline
- Whether the request involves an established OEM part, new design, prototype, custom component, or smaller-quantity order

Established OEM customers often begin the process with controlled drawings and defined production requirements. Customers developing new products, prototypes, custom components, or smaller-quantity orders may still be working from a sketch, sample, or preliminary dimensions. That is enough to begin a conversation.
In either case, share all available information and label undecided details as preliminary, “TBD,” or open to recommendation. This approach reduces assumptions, brings important questions forward, and gives the manufacturer a stronger basis for preparing an accurate quote.

What Should You Include in a Roll Forming Quote Request?
A roll forming quote accounts for the complete manufacturing process – not just the shape of the finished part. The design and production requirements can affect material purchasing, tooling, equipment selection, setup, production speed, secondary operations, inspection, packaging, and shipping.
When essential information is missing, the manufacturer may need to pause the quoting process and request clarification. Providing reliable details upfront helps the team evaluate whether the part is a good fit for roll forming, identify technical questions, and develop pricing based on the actual project requirements.
You do not need every answer before making contact. The goal is to provide enough context for the manufacturer to understand the application and determine what information is still needed.
Start With a Technical Drawing or Part Reference
A technical drawing is usually the most useful starting point for a custom roll forming quote. It communicates the profile, dimensions, angles, bend radii, material thickness, hole patterns, and other features that may affect production.
Submit the latest drawing revision and clearly identify the units of measurement. If a dimension or feature is critical to fit, function, safety, or assembly, identify it clearly on the drawing.
When requesting an existing catalog profile, provide the applicable part number and confirm any project-specific variables. These may include the material, thickness, finished length, hole pattern, finish, and required quantity.
What If You Don't Have a Finished Drawing?
A new product may not have a production-ready drawing yet. In that case, provide a preliminary drawing, dimensioned sketch, photo, physical sample, existing component, assembly drawing, or similar part reference.
Include enough context to explain:
- What the part must do
- Where the part will be used
- Which dimensions are already known
- How the part connects with other components
- Which design decisions remain open
Choosing a manufacturing partner early can help move a custom roll-formed component from concept to production. Additional review of the engineering and tooling requirements may be needed before final production pricing can be prepared.
State the Required Quantity and Part Lengths
Provide the total number of parts or total linear footage required. If the project includes several finished lengths, show the quantity needed at each length.
For a recurring OEM program, include the expected quantity per release and estimated annual volume. This information helps the manufacturer determine whether the project is a single production run, scheduled releases, or an ongoing supply program.
State the finished part length separately from the total volume. An order for 10,000 linear feet could consist of a relatively small number of long sections or thousands of shorter components. Those scenarios may require different cutting, handling, packaging, and shipping plans.
Dahlstrom can cut most profiles to specific lengths ranging from 2 to 40 feet. The appropriate production approach depends on the profile, material, tolerances, volume, and delivery requirements. Additional information is available on Dahlstrom’s roll forming capabilities page.
If future demand is uncertain, provide the initial order quantity and a reasonable forecast range. Label the forecast as an estimate so it is not mistaken for committed production volume.
Specify the Material, Grade, and Thickness
Material influences formability, performance, availability, and cost. When possible, identify:
- The material type
- The grade or specification
- The thickness or gauge
- The temper, hardness, or relevant mechanical properties
- The required surface condition
Dahlstrom roll forms materials that include cold-rolled and hot-rolled steel, high-strength low-alloy steel, galvanized and galvannealed steel, stainless steel, aluminum, copper, brass, and bronze. Published capabilities include material thicknesses ranging from 0.012 to 0.200 inches. Pre-painted, textured, brushed, and pre-perforated materials may also be considered, depending on the application.
If the material has not been selected, describe the part’s operating environment and performance requirements. Explain whether the part will encounter moisture, chemicals, temperature changes, repeated loads, or visible finish requirements.
It also helps to distinguish between a required specification and a general preference. This distinction tells the manufacturer whether alternative materials can be considered.
Identify Required and Critical Tolerances
Tolerances establish how much variation is acceptable in a finished component. They may apply to cross-sectional dimensions, angles, straightness, twist, hole location, or finished length.
Clearly identify the tolerances that affect fit, function, safety, or assembly. Avoid assigning unnecessarily tight tolerances across the entire part. Tighter requirements may affect tooling, processing, inspection, and price without improving the component’s performance.
The measurement method should also be clear. A tolerance can be difficult to evaluate when the datum, callout location, or inspection method has not been defined.
As explained in Dahlstrom’s guide to roll forming tolerances, achievable results depend on the interaction among material, profile geometry, bend count, punched features, and measurement location. Explaining why a tolerance is critical helps the engineering team evaluate the requirement in the context of the complete part.
If the required tolerances are unknown, describe how the part must fit or function instead of estimating a value.
Provide the Required Delivery Date
Include the date when the finished parts must arrive at your facility or jobsite. “As soon as possible” does not give the manufacturer a defined target for production planning.
If the project has several stages, provide separate dates for samples, prototypes, initial production runs, and full releases. For parts that will be produced on an ongoing basis, include the expected ordering frequency.
The requested date helps the manufacturer evaluate material availability, engineering review, tooling development, production capacity, secondary processing, packaging, and transportation. It provides a target for evaluation but does not become a confirmed lead time until the manufacturer reviews the project.
Explain Your Project Type
Identify whether the request involves:
- An established OEM production part
- An existing catalog profile
- A new product design
- A prototype
- A custom component
- A replacement for an existing part
- A smaller-quantity or short-run order
An established OEM program may come with controlled specifications, quality requirements, and predictable demand. A customer developing a new product may know the intended function and basic dimensions while still evaluating the material, tolerances, or final profile.
A smaller-quantity customer may be looking for an existing shape that can be produced without developing new custom tooling. Dahlstrom offers standard channels and angles that may suit projects requiring smaller quantities or less customization. If an existing profile isn’t appropriate, the expected volume and future demand will help determine whether a custom approach should be evaluated.
Being clear about the project type helps the manufacturer ask relevant questions and determine whether the request requires a catalog review, engineering collaboration, tooling evaluation, or production planning.
Include Secondary Operations and Finishing Requirements
In the quote request, include any work required beyond forming the basic profile.
Holes, slots, notches, cutouts, embossments, labels, and stiffening features can affect tooling and production. Show the dimensions, locations, spacing, and tolerances for these features. If a repeating pattern must align with the finished part length, define where the pattern begins and ends.
Dahlstrom’s custom-component capabilities include punching, notching, embossing, lot tracking, and proprietary labeling. Some operations may be incorporated into the roll forming line, while others may require separate processing.
Other required information may include:
- Coating, plating, paint, texture, or protective-film requirements
- Cosmetic standards or surface-direction requirements
- Material certification or traceability requirements
- Inspection and testing requirements
- Special labeling requirements
- Bundling, separators, wrapping, or pallet configurations
- Pack quantities and the delivery location
These details allow the manufacturer to evaluate the finished component rather than quote only the formed profile.
What Happens After You Request a Quote?
After receiving the request, the manufacturer reviews the part design, material, quantity, tolerances, secondary operations, and delivery requirements. The team may ask for clarification, recommend a drawing review, or determine whether an existing profile could meet the project’s needs.
New custom components may require engineering or tooling evaluation before final pricing can be prepared. Projects with complete specifications may move through the review more quickly, although questions can still arise when drawings, purchasing specifications, and quality requirements do not align.
The customer brings knowledge of the application and performance requirements. The roll former evaluates how those requirements can be translated into a repeatable manufacturing process. Clear information on both sides creates a stronger foundation for the quote.
