Technologies for Sheet Metal Processing

Sheet metal processing represents a high–added-value industrial sector, continuously evolving and requiring precision, production continuity and the ability to adapt to different markets.

For over 70 years, Gasparini S.p.A. has stood out in the development of roll forming lines and integrated sheet metal processing systems, delivering tailor-made solutions based on high quality standards to improve productivity, precision and industrial flexibility.

Each system is designed around a specific customer requirement and integrates the technologies needed to achieve the final configuration of the required profile.

Sheet metal processing technologies

Sheet metal processing technologies include the set of techniques, processes and machines used to transform coils or strips into the desired final cross-section, through forming and transformation actions.

The main technologies include:

• Cold roll forming
• Bending
• Cutting
• Punching
• Clinching
• Deep drawing
• Curving
• Welding
• Stacking and unloading

Cold roll forming: the core of Gasparini production

Cold roll forming is a sheet metal processing technique that enables the production of complex, high-precision profiles through a sequence of shaped rollers. It is ideal for mass production thanks to high speed, repeatability and reduced scrap.

Gasparini is a roll forming specialist and, as a global reference company, designs and manufactures roll forming lines and auxiliary technologies, delivering complete production systems.

The high quality and precision of Gasparini roll forming are the result of strict internal standards for roll and component design and manufacturing, supported by an organizational model based on lean production principles. This approach enables the development of customized roll forming machines, engineered according to specific profile design requirements and customer production needs.

The experience and know-how of our designers, technicians and assembly teams have enabled Gasparini to specialize in a wide range of auxiliary technologies required to obtain the finished product.

Innovation in roll forming: interchangeable cassettes, TWIN and REVOLVER

Technological evolution has led to the development of systems designed to increase flexibility and productivity:

• Interchangeable cassettes: enabling format changes for the roll forming of structural profiles, door and sectional door frames, and other applications.
• TWIN system: roll forming technology designed for maximum flexibility and high automation in the production of supermarket and industrial shelving, structural profiles, cable trays and other metal profiles.
• REVOLVER system: a fully automated roll forming system for roofing and cladding, developed for multi-profile production.

Most commonly used materials in sheet metal processing

In roll forming, material selection directly determines profile performance. Gasparini roll forming systems process a wide range of materials:

• pickled hot-rolled steels
• galvanized, pre-painted and stainless steels
• high-strength steels

Each material requires specific roll forming parameters: cold-rolled steels ensure dimensional accuracy, stainless steel guarantees long-term durability, while pre-painted materials provide finished surfaces directly at the line exit.

Choosing the right material means balancing strength, corrosion protection and formability. Gasparini roll forming lines automatically adapt to variable thicknesses – from 0.1 to 12 mm / from 39 gauge to 0.47 in – maintaining maximum precision even with different mechanical properties. Gasparini turns material versatility into a competitive advantage – delivering profiles that combine performance, design and efficiency.

Digitalization and automation in sheet metal processing

For Gasparini, digitalization is a key element in making our lines flexible and fully connected.

Our approach integrates:

• Advanced and customizable PLCs to increase operational efficiency and manage production changeovers or adjustments even during operation
• Intuitive and connected HMIs to dynamically respond to production variations
• Real-time data exchange between PLCs, HMIs and ERP systems
• Automated handling processes and robotic palletizing

TWIN and REVOLVER roll forming systems enable fully automatic profile changeovers, while the digital synchronization of downstream operations (punching, cutting, bending) ensures production continuity and reduced setup times.

Applications across different industrial sectors

Gasparini roll forming lines serve multiple sectors: logistics, construction, electrical distribution, solar, road infrastructure and automotive. Among the most requested applications are roll forming systems for supermarket shelving and warehouse storage, cable trays, wall and roofing cladding, and structural profiles for buildings and solar installations.

Each sector has different priorities – precision for floor decking profiles, aesthetics for façades and gutters, tight tolerances for profile coupling, strength for pallet racking or lightweight structures for supermarket shelving.

Thanks to flexible automation and customized tooling, Gasparini enables rapid transitions between product families, responding effectively to market demands. Compared to traditional press lines, roll forming offers higher repeatability, integration of secondary operations (clinching, welding, bending) and optimized logistics through in-line automation.

Quality control and internal production monitoring

Quality is verified at every stage of the process, from design to final testing.
Thanks to the Digital Twin, Gasparini can simulate, analyze and optimize the internal production cycle, ensuring:

• faster project development
• greater flexibility and precision in customization
• constant monitoring of work progress
• dimensional and geometrical control of profiles
• continuous verification across all phases and reliable delivery times.

This approach ensures reliability, traceability and consistent quality over time. Likewise, to ensure profile compliance, we use measuring equipment that guarantees dimensional and geometrical verification, tolerance compliance and repeatability of results, thus validating each new system during the final testing phase.
