The profiles produced on this production line are all in U-shaped forms, specifically the U post and spacer block within the guardrail system. The spacer block serves as a resistance block installed between the post and guardrail beam, providing cushioning upon impact.
Typically, U posts and spacer blocks are made of 5mm cold-rolled or hot-rolled steel, with hole punching preceding the forming process. These holes are reserved for screw and nut installation.

Real case-Description
Hydraulic decoiler
Engineered with efficiency and safety in mind, the hydraulic decoiler is driven by a powerful hydraulic station. Featuring an outward coil retainer, it prevents the steel coil from slipping off, while the press arm firmly secures the coil, ensuring worker safety by preventing unexpected springs up.
Leveler
By alleviating internal stress within the coils, it optimizes them for punching and forming. Integrated with the forming machine base, the leveler saves valuable floor space and reduces land costs in your production line setup.
Hydraulic punch
The hydraulic punch is capable of punching holes in steel coils up to 5mm thick, ready for screw installations. Connected to the roll forming machine base, it ensures precise operations, albeit requiring brief pauses during punching.
For increased production speeds, standalone hydraulic punch solution is also available.
Roll forming machine
At the heart of the production line lies the roll forming machine. Its robust cast-iron structure effortlessly handles 5mm thick steel coil forming. All roll forming rollers are driven by the gearbox system, crafted from Gcr15, the high-carbon chromium-bearing steel rollers offer exceptional hardness and wear resistance, further enhanced by chrome plating. Meanwhile, heat-treated 40Cr shafts guarantee durability and reliability even under the most demanding conditions.
Encoder & PLC
Precision meets control with the encoder and PLC system. Seamlessly converting steel coil length into electrical signals, the encoder provides accurate feedback to the PLC control cabinet. The production speed, quantity per cycle, cutting lengths can all be set on the PLC control cabinet, and limit the cutting errors within ±1mm. Customers can set the cutting length according to their needs through the operation panel.
Hydraulic cut
Each cut leaves behind smooth, burr-free edges, eliminating waste while ensuring impeccable precision. This way, it can save costs for customers. It should be noted that the roll forming machine pauses during each cutting operation.
We also offer one higher speed solution that the roll forming machine doesn't stop when cutting if you need.
Hydraulic station
Efficiency meets reliability with our state-of-the-art hydraulic station. Equipped with cooling electric fans, it efficiently dissipates heat, maintaining optimal working temperatures for prolonged operations. With minimal failure rates, our hydraulic stations guarantee durability and longevity, ensuring uninterrupted production workflows.
