How a Galvanized Sheet Roll Forming Machine Works

Whether you’re working with carbon steel, stainless or aluminum, a galvanized sheet roll forming machine can help you create the right components to meet your design specifications.galvanized sheet roll forming machine This type of forming process is one of the fastest for producing constant-profile parts, and it’s also able to shape metal that has already been painted or plated. It can even be done at room temperature, unlike hot forming, which can result in warping or distortion.

The forming process begins when a coil or long individual strip is fed through a roll forming line, which transforms flat metal into contoured cross-sectional profiles. The line consists of consecutive bending stations, each of which nudges the metal towards its targeted profile. The forming lines can also incorporate additional operations like notching or punching, which allows you to add features such as mounting holes, notches and grooves. The bending stations can be symmetrical or non-symmetrical, depending on the desired profile.

Each station consists of a series of precision-contoured metal dies called rollers, which progressively bend the incoming strip of metal to form it into a particular profile. The bending stations are connected by powered drive rolls, which move the strip of metal in coordination with the rollers. The system can also include a shear, which cuts the shaped strip to its ordered product length. This can be located before or after the forming line, depending on the size and complexity of the profile being produced.

After the final bending station, the strip of metal is sheared to its finished length. A shear can be either manually operated or automated with a flying cut-off. This style of cutting allows the shear to operate while the system continues to shape the strip, increasing processing efficiency and throughput. The shear can also be used to shear off pieces of the metal that are too small to be useful, such as stubs or trimmings.

The resulting shaped metal can be used for a variety of applications, including building construction, industrial fabrication and storage systems, and residential roofing and siding. The material is often chosen for its resistance to corrosion, especially in environments that experience high levels of moisture. Galvanized metal is especially well-suited for use in building structures, as it provides a durable protective coating against the elements. The coating is typically zinc, which provides a level of protection that prevents the metal from rusting and decaying over time.
