Products
Roll Forming Products We Manufacture
We make custom metal profiles based on your drawing, sample or application requirement. Common roll forming products include:
Closed Profiles & Welded Tubes
Round tubes, square tubes, rectangular tubes and special welded profile shapes.
Panel Profiles
Custom panel profiles for equipment, enclosures, frames, covers and industrial products.
Special-Shaped Sections
Non-standard profiles with custom geometry, hole patterns, welded features or secondary forming. For cold drawing/ extrusion of steel, click here.
Post-Forming Operations
Hole punching, welding, pipe bending, surface coating, galvanizing, powder coating and assembly.
Tube & Profile Projects
OEM profile projects can be supplied as individual parts, welded assemblies or packed export-ready components.
Process
Continuous Roll Forming for Repeatable Metal Profiles
Roll forming is ideal when your product needs a long, consistent cross-section with repeatable dimensions. A flat strip or coil is gradually bent through a series of roll stations, then cut to the required length.
For suitable projects, CSMFG can integrate multiple steps into one production flow:
- Coil feeding
- Cold roll forming
- Hole punching
- Online welding
- Cut-to-length production
- Surface repair or coating preparation
- Final inspection and packing
This matters because continuous roll forming can reduce secondary operations, improve repeatability and lower unit cost once the profile is validated.

Aluminum capability
Aluminum Roll Forming & Aluminum Profile Projects
Need lighter parts or better corrosion resistance? CSMFG supports aluminum profile projects through roll forming, extrusion, welding, machining and surface finishing.
Aluminum is attractive for frames, covers, channels, trims, equipment panels and lightweight assemblies because it can weigh about one third of an equivalent steel part and naturally forms a protective oxide layer that helps resist corrosion.
Aluminum behaves differently from steel. High-strength aluminum can have more springback and lower formability, so good tooling design and process planning are critical before production.
For projects where extrusion is a better route than roll forming, CSMFG can also support aluminum extrusion profiles. Our aluminum extrusion capability lists material options including 6063, 6060, 6005, 6061, 6082, 2024, 3003, 5052, 7003 and 7075, with finishes such as anodizing and Teflon coating.
Not sure whether to use aluminum roll forming or extrusion? Send us the profile drawing. We will suggest the practical manufacturing route.
For aluminum roll forming, our engineers review:
- Alloy and temper
- Bend radius
- Springback risk
- Surface appearance requirements
- Scratching and handling control
- Profile geometry
- Annual volume and tooling economics

Why CSMFG
Why Choose CSMFG as Your Roll Forming Supplier in China
Choosing a roll forming supplier in China is not just about the lowest unit price. The real risk is miscommunication, unstable quality, tooling mistakes, late delivery and parts that do not fit during assembly.
CSMFG is built for custom manufacturing projects that need engineering discussion, supplier coordination and export execution.
Engineering-Led Communication
Our English-speaking project managers and engineers help review drawings, tolerances, materials and production risks before quoting.
One-Stop Manufacturing
Roll forming can be combined with welding, tube bending, machining, coating, assembly and packing under one coordinated supply chain.
Quality Control Process
We use SOPs, material checks, dimensional inspection, coating checks, salt spray testing, weld testing and third-party labs where required.
China Cost Advantage Without Losing Control
We combine factory-direct pricing with engineering review, QC documentation and export support.
Prototype to Production
We can support early engineering samples, pilot runs and repeated production after the roll forming process is stable.

FAQ
Roll Forming FAQ
What is cold roll forming?
Cold roll forming is a metal forming process where strip or coil material is gradually bent at room temperature through multiple roll stations to create a long, consistent profile. It is suitable for custom channels, tubes, rails, panels and structural sections.
What is continuous roll forming?
Continuous roll forming means the strip is continuously fed through the roll forming line, shaped by multiple roll stations and then cut to length. Punching, notching, welding and other operations can often be integrated into the line.
Do you make aluminum roll formed profiles?
Yes, we can evaluate aluminum profile projects for roll forming. Aluminum is useful when weight reduction, corrosion resistance or appearance matters. Because aluminum can have greater springback than mild steel, we review alloy, temper, geometry and tolerance before quoting.
When is aluminum extrusion better than aluminum roll forming?
Extrusion is often better for thick, complex or enclosed aluminum profiles. Roll forming is usually better for thinner sheet or coil-based profiles with a consistent cross-section and production volume. Send us the drawing and we will suggest the more practical route.
What roll forming products do you supply?
We supply custom roll formed products such as U channels, steel tubes, rectangular tubes, panel profiles, welded profiles and special-shaped metal sections.
Can you combine roll forming with welding and coating?
Yes. Depending on the design, we can combine roll forming with hole punching, online welding, cut-to-length, pipe bending, surface coating, galvanizing, powder coating and assembly.
Are you a roll forming supplier in China?
Yes. CSMFG is a China-based contract manufacturer supplying custom roll formed metal profiles and related manufacturing services for overseas OEM buyers.
