Unlike dedicated machines that produce only one profile, this unit is designed to manufacture both W-beam (2-wave) and 3-wave (thrie beam) guardrails. The key difference lies in the rolling tools, which are compatible with both profiles. During a changeover, only the last few forming stations are adjusted or made ineffective, and the cutting dies are swapped. This saves the cost and floor space of purchasing and operating two separate machines.

According to the machine specifications listed, the equipment processes galvanized steel strips. The material width can be either 480mm or 750mm–with a note that it is ‘subject to final design’–and the listed thickness range in the specification table is 2.5–4mm. Note that the descriptive text mentions 1.8–3.5mm, so the acceptable range depends on your final roller and machine configuration. Please confirm exact strip width and thickness requirements with MTC for your specific project.

The punching system is located at the feeding section of the machine, before forming. It uses a Yl32-315 type hydraulic plus pneumatic punching machine with 4 pillars. The punching dies can accommodate different hole compositions, meaning the machine can produce various hole patterns for different guardrail standards. Punching shares the same hydraulic system as the cutting unit. Specific punch force values are not listed, so please contact MTC for details on hole size, spacing, and patterns available.

The listed forming speed is 0–20 meters per minute, excluding cutting and punching time. Because cutting is a ‘stop and cut’ operation (the hydraulic cutting tool stops the line to make the cut), the actual final production rate depends on several factors: the guardrail length you are producing, the number and type of punching operations per piece, and the acceleration/deceleration settings of the PLC. Typically, longer guardrail sections yield higher effective line speeds per piece. For a specific hourly output estimate, you should compare your part length and punch pattern with the 20 m/min forming capability.

The control system uses a Panasonic PLC with Inverter drives, a CHNT transformer, and Omron encoders. The machine’s electricity standard is 380V, 50Hz, 3-phase. Total connected power is the sum of the main forming motors (2x22KW), the hydraulic power for punching/cutting (18.5KW), the smaller hydraulic power unit for other functions (5.5KW per specification, though text mentions 4KW motor power for another unit), plus the leveler/feeding unit motor (4KW). Always verify your incoming power supply capacity and local electrical codes before installation, and coordinate with MTC for exact single-machine connection requirements.

Yes, the machine is designed with material width adjust-ability in mind. The descriptive text states the machine makes guardrails from steel strips with ‘480mm and 750mm widths adjustable.’ However, the specification table lists material width only as ‘480 & 738mm’ and adds ‘subject to final design.’ This means the adjustable range on your specific unit should be confirmed before ordering. In general, the rollers and punching dies are arranged to accept these two standard width ranges for W-beam and 3-wave profiles, but exact adjustability must be confirmed with MTC for your project.

The complete line includes (1) a manual decoiler, (2) a feeding unit, (3) a hydraulic cutting tool, (4) a roll forming unit, (5) a transmission unit (gear-boxes and universal joint shafts), (6) a cutting unit, (7) a hydraulic unit for powering cutting and punching, (8) a control system (PLC based), and (9) run-out tables for collecting finished guardrails. This is a fully integrated line from coil to finished cut-to-length guardrail sections. Additional or optional auxiliary equipment like powered decoilers or automatic stackers can be discussed with MTC based on your production requirements.
