Automatic Angle Bead Roll Forming Machine for Light Steel Frame Systems Up to 70 m/min

Modern light steel frame systems and drywall construction require accurate components for wall finishing, corner protection, and interior partition applications. Our Automatic Angle Bead Roll Forming Machine is designed to manufacture galvanized steel angle beads and perforated drywall corner beads used in light steel frame, drywall, plastering, and wall finishing systems.

The production line integrates decoiling, punching, roll forming, and cutting into one continuous process. With automatic PLC control and high-speed forming technology, it helps manufacturers achieve consistent corner bead dimensions, efficient production, and reliable product quality.

Angle Bead for Light Steel Frame and Drywall Construction

Angle bead is an important finishing component used with drywall and light steel frame construction systems. It protects external wall corners and helps create straight, clean, and durable edges.

The profile normally consists of a central metal nose and two wings. Depending on the application, the wings can be perforated or expanded to improve bonding with plaster, joint compound, or other finishing materials.

Galvanized steel angle beads are widely used for interior construction because they provide a good balance of strength, corrosion resistance, and cost.

Typical applications include:

• Light steel frame buildings

• Drywall partition systems

• Plasterboard walls

• Interior wall finishing

• Suspended ceiling systems

• Residential construction

• Commercial buildings

• Modular construction projects

Galvanized Steel Angle Bead Production

The angle bead roll forming machine processes galvanized steel or Galvalume strips into accurately shaped corner bead profiles.

During production, the steel strip is first loaded onto the decoiler and then continuously fed into the punching section. The punching system creates the required perforation pattern on the wings.

After punching, the material enters the roll forming section. Multiple forming stations gradually shape the flat strip into the required angle bead profile without damaging the galvanized surface.

Finally, the automatic cutting system cuts the formed profile to the preset length.

The complete production process can be arranged as:

Decoiling → Feeding → Punching → Roll Forming → Cutting → Finished Product

This continuous configuration reduces manual handling and improves production efficiency.

Perforated Drywall Corner Bead

Perforated drywall corner bead is commonly used on external corners of gypsum board and plasterboard walls.

The holes distributed along the wings allow plaster or joint compound to pass through the profile, creating a strong mechanical connection after installation. This helps maintain a straight corner while reducing the risk of cracking and edge damage.

Depending on the customer's requirements, the machine can be configured for different:

• Profile dimensions

• Wing widths

• Hole patterns

• Hole spacing

• Material thickness

• Finished lengths

This flexibility allows manufacturers to supply different corner bead specifications for various construction markets.

Expanded Metal Corner Bead

In addition to perforated profiles, the production solution can be designed for expanded metal angle bead applications.

Expanded metal wings provide a larger open area for plaster bonding and can be suitable for certain wall finishing systems and uneven surfaces.

Depending on the required application, corner beads can be manufactured using galvanized steel or other suitable materials.

Common finished lengths include 2400 mm, 2700 mm, and 3000 mm, while profile dimensions can be customized according to project requirements.

High-Speed Angle Bead Roll Forming Machine

The Automatic Angle Bead Roll Forming Machine is designed for continuous and efficient production.

The machine integrates several processes into one production line, including automatic decoiling, high-speed rotary punching, precision roll forming, and automatic cutting.

A PLC control system manages production parameters such as forming length, production quantity, and batch operation. This allows operators to quickly adjust production requirements while maintaining stable output.

The forming speed can reach up to 70 m/min, depending on the material, profile size, punching pattern, and machine configuration.

Accurate Profiles for Light Steel Frame Projects

Although angle beads are mainly finishing components, their dimensional accuracy is important for achieving professional results in light steel frame and drywall construction.

A precisely formed corner bead provides a straight reference edge for plastering and finishing work. Consistent dimensions also make downstream installation easier and reduce unnecessary adjustment during construction.

The automatic roll forming process helps maintain stable profile geometry throughout continuous production, making the equipment suitable for manufacturers supplying large quantities of construction profiles.

Automatic Production for Higher Efficiency

Traditional manual production methods require multiple processing stages and considerable labor. An automated corner bead production line combines these operations into a continuous manufacturing process.

The main advantages include:

• Continuous production

• Automatic punching

• Accurate roll forming

• Automatic length cutting

• PLC-controlled operation

• Stable profile dimensions

• Reduced manual handling

• High production efficiency

For manufacturers serving the light steel frame and drywall construction market, this configuration can help improve production capacity while maintaining consistent product quality.

Flexible Solutions for Different Markets

Construction standards and corner bead specifications vary between markets. Therefore, the machine can be customized according to different production requirements.

Available options may include customized profile dimensions, punching patterns, material thickness, cutting lengths, electrical configurations, and machine layouts.

For customers producing multiple specifications, suitable tooling solutions can also be developed to improve production flexibility.
