Guard Rail Roll Forming Machine

Hangzhou IUWON Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of guard rail roll forming machine in China. With abundant experience, we warmly welcome you to buy high quality guard rail roll forming machine from our factory. Good service and reasonable price are available.

Corrugated Beam Structure

The characteristic corrugation of a guard rail increases the section's structural rigidity compared with a flat steel plate. During forming, the steel strip passes through dedicated stations that progressively establish the waves and longitudinal edges.

The forming sequence must maintain the relationship between the corrugated body and mounting holes. If hole positions shift relative to the beam centerline, installation with posts, spacers, and bolts can become difficult. The machine therefore combines profile forming with controlled punching and length measurement.

The tooling can be designed for different beam standards and dimensions, including profiles with different wave depths, beam widths, and material thicknesses.

Guard Rail Machine Parameters

Punching, Forming & Cut-Off in One Line

Guard rail beams normally require repeated mounting holes along their length. These holes allow the beam to be attached to posts through bolts, spacers, and other connecting hardware.

The punching section can be positioned before or after the main forming operation according to the beam design. For flat-strip punching, the hole pattern can be processed before the corrugation is created. This approach can provide stable hole positioning when multiple fixing holes are arranged across the strip width.

After forming, the continuous beam is cut into specified lengths. The PLC records the production length through an encoder and coordinates the punching and cutting sequence.

Production Line Configuration

Road Safety Barrier Applications

The finished guard rail beams are installed horizontally along roads and connected to vertical posts. Depending on the road design, the barrier can be positioned along the outer edge of a roadway, central median, bridge approach, ramp, or other hazardous section.

Common applications include:

Highway roadside barriers

Expressway safety barriers

Central median guard rails

Bridge approach barriers

Tunnel safety barriers

Road curve protection

Ramp and interchange barriers

Industrial road safety systems

Parking and traffic separation areas

The production line can be configured for different beam lengths and hole patterns according to the installation system. Additional components such as spacer blocks, terminal sections, and connection parts can be manufactured separately or through dedicated equipment.

Guard Rail Standards & Production Matching

Road safety projects may specify particular beam dimensions, hole spacing, material thickness, galvanizing requirements, and impact-performance classifications. These requirements should be established before the forming rolls and punching tooling are designed.

For this reason, the machine configuration can be matched to the required guard rail specification, including:

For heavy-gauge highway barriers, the forming section, shafts, transmission, and machine frame can be reinforced to handle the higher forming load. The final configuration should be established from the required guard rail drawing and applicable road-safety specification so that the produced beam is compatible with its posts, connectors, and installation hardware.
